This platform is a great operating system that can be deployed on various systems like dedicated servers, cloud servers, or virtual machines. It can be said that one of the best solutions to secure the hosting environment on servers is to isolate the file system and keep the user’s process secret.

What is CloudLinux?

CloudLinux is an operating system that helps create a secure and stable platform for shared hosting. This cloud computing system is based on CentOS and Cause users to have more control over server resources:

Features of CloudLinux

– Isolation of user accounts prevents users from influencing each other.

– It prevents users from seeing each other’s configuration files or private information.

– Allows you to monitor and control limits such as RAM, CPU, and I/O.

– Monitor and implement MySQL usage.

– It provides CageFC, which is a type of file system.

– It allows users to choose between different versions of php

– Prevent symbolic link attacks

– It is compatible with all major control panels.

Install CloudLinux on a Dedicated Server

Now, it’s time to find out how to install CloudLinux on your dedicated server. To start and install CloudLinux on a dedicated server, you must have a dedicated server in the first step. Therefore, we suggest you visit the Cheap Dedicated Server plans presented on our website. So follow the instructions in this section carefully so that you can do the installation successfully.

The first step is to run the following command to download cldeploy script:
```
wget https://repo.cloudlinux.com/cloudlinux/sources/cln/cldeploy

Tutorial Install and Configure Cacti on AlmaLinux 8
Certainly, one of the important pillars of any network is having a monitoring system to check the structure of the network. Cacti is one of the free network monitoring software. If you want to compare the monitoring tools, Cacti is in a higher position in order to its open-source and availability of resources. If you follow this post until the end, you will learn how to Install and Configure Cacti on AlmaLinux 8 step by step.

What is Cacti?

Cacti make a connection to your devices using the SNMP protocol and analyze them during the interval. Cacti software is based on PHP/MySQL, which is basically installed on Linux Operating Systems and uses the RRDTool software to present its graphs. It should be noted that Cacti also allows you to provide a monitoring panel to your customers. In this software, you can specify which ports the subscriber will have access to after logging in. Cacti has made the monitoring process powerful by having a web-based management environment and various templates for different operating systems and devices.

Prerequisites

– A Linux VPS Server with AlmaLinux OS

– Apache Webserver

– MariaDB Database Server

– PHP and PHP extensions

– SNMP and RRDTool

Follow us in the continuation of this article by teaching how to install and configure Cacti on Almalinux.

How to Install Cacti on AlmaLinux 8

Cacti is a web-based tool, so you need to create an Apache web server on which to run Cacti. You can install the Apache web server by entering the following command:
```
sudo dnf install httpd -y
```
To start the Apache web server, execute the following command:
```
sudo systemctl start httpd
```
Now you should enter the following command to enable the Apache webserver:
```
sudo systemctl enable --now httpd
```
At this point, Cacti requires a database to store the collected data, which in this article uses the MariaDB database. To install the MariaDB database, execute the following command:
```
sudo dnf install -y mariadb-server mariadb
```
You should enter the following command to start the MariaDB database:
```
sudo systemctl start mariadb
```
Then you can use the following command to enable MariaDB to start on boot:
```
sudo systemctl enable mariadb
```
Since Cacti is written in PHP, PHP and PHP extensions should be installed. So use this command to add the Remi repository:
```
sudo dnf install dnf-utils http://rpms.remirepo.net/enterprise/remi-release-8.rpmmi
```
Then you should enable the DNF module for PHP installation by entering the following command:
```
sudo dnf module reset php
sudo dnf module enable php:remi-7.4
```
Now you can install PHP and PHP extensions by executing the following commands:
```
sudo dnf install @php
sudo dnf install -y php php-{mysqlnd,curl,gd,intl,pear,recode,ldap,xmlrpc,snmp,mbstring,gettext,gmp,json,xml,common}
```
Use the following command to enable the PHP-fpm service:
```
sudo systemctl enable --now php-fpm
```
In this step, you should install SNMP and RRDTool, which are needed to gather and analyze system metrics:
```
sudo dnf install -y net-snmp net-snmp-utils net-snmp-libs rrdtool
```
You can start it with the following command:
```
sudo systemctl start snmpd
```
Enter the following command to enable snmpd:
```
sudo systemctl enable snmpd
```
The next step is to create a database and user for the Cacti and then grant all the necessary privileges to the Cacti user. So, enter the following command:
```
mysql -u root -p

MariaDB [(none)]> CREATE DATABASE cactidb;
MariaDB [(none)]> GRANT ALL ON cactidb.* TO cacti_user@localhost IDENTIFIED  BY 'passwd123';
MariaDB [(none)]> FLUSH PRIVILEGES;
MariaDB [(none)]> EXIT;
```
Now you should import the mysql test data timezone.sql file into the MySQL database:
```
mysql -u root -p mysql < /usr/share/mariadb/mysql_test_data_timezone.sql
```
Now you should enter the following command to connect to the MySQL database and then provide the Cacti user access to the mysql.time zone name table:
```
MariaDB [(none)]> GRANT SELECT ON mysql.time_zone_name TO cacti_user@localhost;
MariaDB [(none)]> FLUSH PRIVILEGES;
MariaDB [(none)]> EXIT;
```
Then you should add the following configuration to the mariadb-server.cnf file under the [ mysqld ] section:
```
sudo vi /etc/my.cnf.d/mariadb-server.cnf
```
Remember to paste the following configuration.
```
collation-server=utf8mb4_unicode_ci
character-set-server=utf8mb4
max_heap_table_size=32M
tmp_table_size=32M
join_buffer_size=64M
# 25% Of Total System Memory
innodb_buffer_pool_size=1GB
# pool_size/128 for less than 1GB of memory
innodb_buffer_pool_instances=10
innodb_flush_log_at_timeout=3
innodb_read_io_threads=32
innodb_write_io_threads=16
innodb_io_capacity=5000
innodb_file_format=Barracuda
innodb_large_prefix=1
innodb_io_capacity_max=10000
```
You can exit after saving the changes.

Because the Cacti package is available in the EPEL (Extra Packages for Enterprise Linux) repository. First release it with the following command:
```
sudo dnf install epel-release -y
```
Now you can install the Cacti monitoring tool by executing the following command:
```
sudo dnf install cacti -y
```
Then you should verify the installation of Cacti with the following command:
```
rpm -qi cacti
```
Now to determine the default Cacti database path, execute the following command:
```
rpm -ql cacti | grep cacti.sql
```
Then you should import the default cacti database tables into the MariaDB cacti database using the following command:
```
mysql -u root -p cactidb < /usr/share/doc/cacti/cacti.sql
```
You should modify the cacti configuration file according to the following database details:
```
sudo vim /usr/share/cacti/include/config.php
```
Now you should change the database name, username, and password to reflect the name you have already created and then set the timezone in the php.ini file. Remember to change the following parameters:
```
date.timezone = Africa/Nairobi
memory_limit = 512M
max_execution_style = 60
```
At this point, you need to set the cron for Cacti. To do this, you should first edit the /etc/cron.d/cacti file:
```
sudo vim /etc/cron.d/cacti
```
To have a Cacti poll for data every 5 minutes, you can uncomment the following line:
```
*/5 * * * *   apache /usr/bin/php /usr/share/cacti/poller.php > /dev/null 2>&1
```
After saving the changes, you can exit the configuration file.

Modifying the Apache configuration file enables remote access to Cacti. To do this, enter the following command:
```
sudo vim /etc/httpd/conf.d/cacti.conf
```
Now you should change the following lines in the file:

– Modify Require host localhost to require all grants.

– Change Allow from localhost to Allow from network subnet.

– Specify your network subnet.

To apply the changes, just restart the Apache and PHP-fpm services with the following command:
```
sudo systemctl restart httpd
sudo systemctl restart php-fpm
```
Finally, you need to enable HTTP service on your Firewall by executing the following command:
```
sudo firewall-cmd --permanent --add-service=http
sudo firewall-cmd --reload
```
How to Configure Cacti on AlmaLinux 8

First, you should visit your server’s IP with the following command:
```
http://server-ip/cacti
```
After viewing the login page, you should log in with the default credentials:
```
Username: admin
Password: admin
```
Then click on Login:

Now you need to set the default Cacti admin login password:

Next, you should accept the GPL license agreement and then click on Begin:

Cacti execute pre-installation tests to ensure that the necessary PHP modules and database settings are installed. Then, click Next to continue:

Now you should choose the New Primary Server as the type of installation and then verify the database connection parameters are right:

At this point, you can check for directory issues and confirm that there are proper permissions. Then click on Next; but if there is a problem you should click on Previous and correct the problems:

Then the installation of binary paths of the required packages is checked by the installer:

Tutorial Set Up Time Synchronization on Rocky Linux
Accurate timekeeping is a critical component in the deployment of modern software. On the other hand, it should be noted that out-of-sync time can cause errors, data corruption, and other difficult debugging issues. By reading this article, you will learn how to Set Up Time Synchronization on Rocky Linux. Therefore, if you are interested in Rocky Linux distribution, we suggest that you stay with us until the end of this article.

What is Time Synchronization?

Time Synchronization is the process of synchronizing the time of independent clocks. Clocks will diverge without synchronization. Clocks and timepieces often use relatively low-cost components that are not accurate. Time Synchronization creates time accuracy between computer clocks in an Ethernet system.

A client’s time may be synchronized with another server, a reference time source such as a radio or satellite receiver, or a GPS time server. Typical time service configurations use additional servers and diverse network paths to provide high accuracy and reliability. In the continuation of this article, learn about the setup time synchronization on Rocky Linux.

How to Set Up Time Synchronization on Rocky Linux

First, you should buy a Linux VPS with the Rocky Linux Operating system. We recommend that you visit the quality and affordable plans on our website. In the beginning, you should list the available time zone by entering the following command:
```
sudo timedatectl list-timezones
```
Now you need to set the timezone of your location using the following command:
```
sudo timedatectl US/Canada
```
There are two types of NTP daemons including chronyd and ntpd. To avoid two NTP daemons from running on the same machine at a time, select one and use it.

In this article, you can synchronize time with the help of two NTP daemons:

1) Time Synchronization using chronyd which is suitable for virtual systems.

2) Time Synchronization using ntpd which is suitable for the network systems.

Time Synchronization Using chronyd

First, you can install the chronyd package with the following command:
```
sudo yum install chrony
```
chronyd can be used to manually synchronize Rocky Linux server time with the remote NTP server:
```
chronhyd -q 'server 0.europe.pool.ntp.org iburst'
```
Then run the following command to start the chronyd service:
```
sudo systemctl start chronyd
```
Now you should edit the configuration file:
```
sudo vi /etc/chrony.conf
```
Next, you should add the following lines:
```
server 0.centos.pool.ntp.org iburst
server 1.centos.pool.ntp.org iburst
server 2.centos.pool.ntp.org iburst
server 3.centos.pool.ntp.org iburst
```
```
server 0.rhel.pool.ntp.org iburst
server 1.rhel.pool.ntp.org iburst
server 2.rhel.pool.ntp.org iburst
server 3.rhel.pool.ntp.org iburst
```
Now save the file and exit and then restart the services by entering the following command to apply the changes:
```
sudo systemctl restart chronyd
```
You need to enable these services to run at every boot:
```
sudo systemctl enable chronyd
```
You can verify if your time system is synchronized or not with the following command:
```
chronyc tracking
```
Reference ID is the ID and name of the server with which your system time is currently synchronized. Stratum indicates the number of hops away from the server connected to the reference clock.

The following command can list information about the current time sources that chronyd uses:
```
chronyc sources
```
You can list information about drift speed and offset estimation of any source that uses chronyd with the following command:
```
chronyc sourcestats -v
```
Time Synchronization Using ntpd

First of all, install the ntpd package by executing the following command:
```
sudo yum install ntp
```
Next, you need to start the ntpd services using the following command:
```
sudo systemctl start ntpd
```
Now you should edit the configuration file.
```
sudo vi /etc/ntp.conf
```
Then you should add the following lines:
```
server 0.centos.pool.ntp.org iburst
server 1.centos.pool.ntp.org iburst
server 2.centos.pool.ntp.org iburst
server 3.centos.pool.ntp.org iburst
```
```
server 0.rhel.pool.ntp.org iburst
server 1.rhel.pool.ntp.org iburst
server 2.rhel.pool.ntp.org iburst
server 3.rhel.pool.ntp.org iburst
```
Save the file and exit.

Now you need to restart the services by executing the following command for the changes to take effect:
```
sudo systemctl restart ntpd
```
Finally, you should enable services using the following command to run them on every boot:
```
sudo systemctl enable ntpd
```
Conclusion

Time Synchronization is essential to determine certain activities of a computer. Every modern system has a mechanism that automatically sets the time of the machine. NTP is one of these mechanisms, and this article taught you how to synchronize time with your NTP server. In this article, you were taught how to set up Time Synchronization on Rocky Linux.

How To Install and Secure Memcached on Ubuntu 22.04
Memory object storage systems such as Memcached can optimize the performance of the backup database by temporarily storing information in memory and preserving frequently requested records. This will reduce the number of direct requests to your databases. We’ll look at how to add authentication to secure Memcached using Simple Authentication and Security Layer (SASL), as well as how to connect Memcached to a local or private network interface to make sure only on networks trusted by users. After reading this post, you will fully learn How To Install and Secure Memcached on Ubuntu 22.04. Therefore, we suggest you stay with us until the end of this article.

What is Memcached?

Memcached is a very powerful and free cache system that has been released as open source. Memcached is software for performing cache operations on Dynamic website servers that will make better and more efficient use of resources. Typically, it is using as a cache system to speed up applications by storing various objects from the results of database conversations.

This system is typically using to speed up websites that use the database, using data storage and objects in main memory (RAM) to reduce the number of times the data is read from an external data source (for example, the database). In the continuation of this article, you will learn about Install and Secure Memcached on Ubuntu 22.04

Prerequisites

A Linux VPS Ubuntu 22.04 server

– Non-root sudo user

– firewall enabled.

Install and Secure Memcached on Ubuntu 22.04

In this section, we are going to teach you step-by-step how to Install and Secure Memcached on Ubuntu 22.04. If you do not have Memcached installed on your server, install it from the official Ubuntu repositories. First, make sure your local package list is updated using the following command:
```
sudo apt update
```
Install the official package of memcached as follows:
```
sudo apt install memcached
```
You can install libmemcached-tools, which contain various tools that you can use to check, test, and manage your Memcached server. Add the package to the server using the following command:
```
sudo apt install libmemcached-tools
```
Memcached is installed as a service on your server, with tools that allow you to test its connectivity. To launch Memcached, run the systemctl command:
```
sudo systemctl start memcached
```
You can now go to secure the configuration settings.

How to Configure Memcached Network Settings

If the Memcached server only needs to support local IPv4 connections using TCP, you can skip this step and go to the next step. But if you want to configure Memcached to use UDP sockets, Unix domain sockets, or add support for IPv6 connections, follow the steps in this section.

First, make sure your Memcached instance listens to the local IPv4 127.0.0.1 Loopback interface. The current version of Memcached, which ships with Ubuntu and Debian, has its -l configuration parameter configured on the local interface to receive only connections from the server where Memcached runs.

Use the following command to verify that Memcached is currently connected to the local IPv4 127.0.0.1 interface and is listening for TCP connections:
```
sudo ss -plunt
```
The flags will alter ss output in the following ways:

-p adds the name of the process that is using a socket

-l limits the output to listening sockets only, as opposed to also including connected sockets to other systems

-u includes UDP-based sockets in the output

-n displays numeric values in the output instead of human-readable names and values

-t includes TCP-based sockets in the output

You should receive the output as follows:

This output verifies that Memcached is connected to the IPv4 Loopback address 127.0.0.1 using the TCP protocol. Now that it has been verified that Memcached is configured to support IPv4 with TCP connections only, you can edit /etc/memcached.conf to support UDP connections, Unix domain sockets, or IPv6.

How to Configuration IPv6 to Memcached

To enable IPv6 connections to Memcached, open the configuration file with Nano or other editors:
```
sudo nano /etc/memcached.conf
```
First, find the following command in the file:
```
. . .
-l 127.0.0.1
```
This line is where Memcached is configuring to listen to the local IPv4 interface. To add IPv6 support, add the IPv6 local loop address command (:: 1) as follows:
```
. . .
-l 127.0.0.1
-l ::1
```
Save and close the file by pressing CTRL+O, then ENTER to save, and then CTRL+X to exit Nano. Also, restart Memcached using the systemctl command:
```
sudo systemctl restart memcached
```
You can now check that Memcached also responds to IPv6 connections by repeating the ss command in the previous section:
```
sudo ss -plunt
```
You should receive the output as follows:
```
Output
Netid State Recv-Q Send-Q Local Address:Port Peer Address:Port Process 
. . .
tcp LISTEN 0 1024 127.0.0.1:11211 0.0.0.0:* users:(("memcached",pid=8889,fd=26)) 
. . .
tcp LISTEN 0 1024 [::1]:11211 [::]:* users:(("memcached",pid=8889,fd=27))
```
Output segments show that Memcached is now responding to TCP connections in the local IPv6 interface. If you want to disable IPv4 support and only listen to IPv6 connections, you can remove the -l 127.0.0.1 command from /etc/memcached.conf and restart the service using the systemctl command.

How to Configure UDP on Memcached

If you want to use Memcached with UDP sockets, enable UDP support by editing the configuration file and opening /etc/memcached.conf using the nano or custom editor, then add the following command to the bottom of the file do:
```
. . .
-U 11211
```
If you do not need TCP support, find the -p 11211 command and change it to -p 0 to disable TCP connections. After editing the file, save and close it by entering CTRL+O to save and then CTRL+X to exit.

Restart the Memcached service with the systemctl command to apply the changes:
```
sudo systemctl restart memcached
```
Memcached listens to UDP connections using the following command:
```
sudo ss -plunt
```
If you have disabled TCP support and enabled IPv6 connections, you should get the following output:
```
[secondary_label Output] 
Netid State Recv-Q Send-Q Local Address:Port Peer Address:Port Process 
. . .
udp UNCONN 0 0 127.0.0.1:11211 0.0.0.0:* users:(("memcached",pid=8889,fd=28))
udp UNCONN 0 0 [::1]:11211 [::]:* users:(("memcached",pid=8889,fd=29))
. . .
```
Note that if you only enable IPv4 connections and enable TCP connections, your output may be different.

How to Configure Unix Domain Sockets

If you want to use Memcached with Unix domain sockets, you can enable support by editing the configuration file. Note that if you configure Memcached to use the Unix domain socket, Memcached disables TCP and UDP support, so before enabling socket support, make sure your applications do not need to connect using those protocols. Open /etc/memcached.conf using Nano or other editors, then add the following commands to the bottom of the file:
```
. . .
-s /var/run/memcached/memcached.sock
-a 660
```
The -a flag specifies the permissions in the socket file. Make sure the user to connect to Memcached is part of the Memcache group on your server, otherwise, a permission message will reject when you try to access the socket. Then, restart the Memcached service with the following command to apply the changes:
```
sudo systemctl restart memcached
```
Make sure Memcached listens to Unix domain socket connections using the following command:
```
sudo ss -lnx | grep memcached
```
The -x flag restricts the ss output to display socket files. You should receive the outputs as follows:
```
Output
u_str LISTEN 0 1024 /var/run/memcached/memcached.sock 20234658 * 0
```
Now that you have configured the Memcached network settings, go to the next step, adding SASL for authentication to Memcached.

How to Add Authorized Users to Memcached

To add authentication users to the Memcached service, use Simple Authentication and Security Layer (SASL), which separates authentication procedures from application protocols. First, add SASL support to the server and configure the user with authentication. Also, enable SASL in the Memcached configuration file and verify that everything is working properly.

Adding a Verified User

To start adding SASL support, you must install the sasl2-bin package, which includes management programs for the SASL user database. This tool helps you create an authenticated user. To install this tool, run the following command:
```
sudo apt install sasl2-bin
```
Create a directory and file that Memcached checks the SASL configuration settings using the mkdir command:
```
sudo mkdir -p /etc/sasl2
```
Now create the SASL configuration file using nano or the editor:
```
sudo nano /etc/sasl2/memcached.conf
```
Add the following command:
```
log_level: 5
mech_list: plain
sasldb_path: /etc/sasl2/memcached-sasldb2
```
In addition to setting the report level, mech_list is set to plain, which indicates to Memcached that it must use its password file and confirm the plain text password. The last command you added specifies the path to the user database file that you will create in the next step. Save and close the file when done.

Now create a valid SASL database and use the saslpasswd2 command with the -c flag to create a new user entry in the SASL database. The user here will be Linda, but you can replace this name with your own. The -f flag specifies the path to the database. This is the path you set in /etc/sasl2/memcached.conf:
```
sudo saslpasswd2 -a memcached -c -f /etc/sasl2/memcached-sasldb2 linda
```
Give the SASL database ownership to the user and memcache group with the following chown command:
```
sudo chown memcache:memcache /etc/sasl2/memcached-sasldb2
```
You now have a SASL configuration that Memcached uses for authentication. Next, verify that Memcached is running with its default settings, then reconfigure it and verify that it works with SASL authentication.

How to Configure SASL Support of the Memcached

First test the connection of the Memcached instance with the memcstat command. This check helps determine if Memcached is running and properly configured before activating SASL and authenticating the user. After making changes to the configuration files, run the command again to check for different outputs. To verify that Memcached is enabled and running using the memcstat command, type the following:
```
memcstat --servers="127.0.0.1"
```
If you are using IPv6, replace :: 1 with IPv4 127.0.0.1. If you are using a Unix domain socket, use the socket path instead of the IP address, for example –servers =/var/run/memcached/memached.sock. When you run the memcstat command and successfully connect to Memcached, you should get the following output:
```
Output
Server: 127.0.0.1 (11211)
pid: 2299875
uptime: 2020
time: 1632404590
version: 1.5.22
. . .
```
Tip: If you are using Memcached with UDP support, the memcstat command cannot connect to the UDP port. Use the following netcat command to confirm the connection:
```
nc -u 127.0.0.1 11211 -vz
```
If Memcached responds, you should get the output as follows:
```
Output
Connection to 127.0.0.1 11211 port [udp/*] succeeded!
```
If you are using Memcached with IPv6 and UDP, the command should look like this:
```
nc -6 -u ::1 11211 -vz
```
Enable SASL now. Add the -S parameter to the configuration file. Reopen the file with Nano:
```
sudo nano /etc/memcached.conf
```
In the file, add the following command:
```
. . .
-S
```
Next, find and ignore the -vv option, which provides full output to /var/log/memcached. The command without comment should be as follows:
```
. . .
-vv
```
Save and close the file. Restart the Memcached service using the systemctl command below:
```
sudo systemctl restart memcached
```
Check the journalctl report for Memcached to make sure SASL support is enabled:
```
sudo journalctl -u memcached |grep SASL
```
You should receive the output command as follows to indicate that SASL support is enabled:
```
Output
Sep 23 17:00:55 memcached systemd-memcached-wrapper[2303930]: Initialized SASL.
```
Now try connecting to Memcached again. Despite SASL support and initialization, the following memcstat command must fail without valid authentication:
```
memcstat --servers="127.0.0.1"
```
The command should not generate output. Enter the following shell command to check the status as follows:
```
echo $?
```
$? Always returns the exit code of the last command that came out. Anything other than 0 indicates process failure. In this case, you should get exit status 1, which indicates the failure of the memcstat command. Re-running memcstat, with the username and password, verifies that the authentication process works.

If you use different credentials, replace the following command with the values linda and your_password:
```
memcstat --servers="127.0.0.1" --username=linda --password=your_password
```
You should receive the output as follows:
```
Output
Server: 127.0.0.1 (11211)
pid: 3831
uptime: 9
time: 1520028517
version: 1.4.25
. . .
```
Memcached is now configuring and executing with SASL support and user authentication.

Allowing Access Over the Private Network (Optional)

Memcached is configuring to listen only to the local loopback interface (127.0.0.1), which protects the Memcached interface from being exposed to outside parties. There may be times when you need permission to access from other servers. You can configure it to connect Memcached to a private network interface.

How to Restrict IP Access with a Firewall

Before configuring settings, set firewall rules to restrict machines that can connect to your Memcached server. You must first record the private IP address of each device you used to connect to Memcached. Once you have a private IP address, add the explicit firewall rule to allow the device to access Memcached. If you are using a UFW firewall, restrict access to the Memcached instance by entering the following commands in the Memcached server:
```
sudo ufw allow from client_system_private_IP/32 to any port 11211
```
If more than one system has access to Memcached over a private network, be sure to add the ufw rules for each device using the above rule as a template. Make changes to the Memcached service to connect to the server’s private network interface.

Memcached Connection to Private Network Interface

Now that your firewall is in place, configure Memcached to connect to the server’s private network interface instead of 127.0.0.1. Find the Memcached server’s private network interface using the IP command below.
```
ip -brief address show
```
Depending on the server network configuration, the output may differ.

Once you find the IP address or private addresses of the server, reopen the configuration file using Nano:
```
sudo nano /etc/memcached.conf
```
Find the -l 127.0.0.1 command that you previously checked or modified, and change the address to match the server’s private network interface:
```
. . .
-l memcached_servers_private_IP
. . .
```
If you want Memcached to listen to multiple addresses, add another similar instruction for each address, either IPv4 or IPv6 using the -l memcached_servers_private_IP format. Save and close the file after completing the steps. Then restart the Memcached service:
```
sudo systemctl restart memcached
```
Check the new settings with ss to confirm the change:
```
sudo ss -plunt
```
Test your external customer connection to make sure you can still access the service. Also, check the access of an unauthorized client (try connecting without a username and password) to make sure your SASL authentication works properly. Also, try connecting to Memcached from another server that is not allowed to connect to make sure the firewall rules created are effective.

Tutorial Add a New DNS Zone with WHM on Dedicated Server

In this tutorial, you will learn how to add a new DNS zone with WHM on the dedicated server. To explain this process with an example, we will assume that you have a DNS server with Cpanel permission. In order to be able to display your site on the internet, the only way is to setup the DNS server correctly. So you need to add a DNS zone for your address and run it in the right way.

What is the DNS Zone?

DNS is the domain name system and it has the role of converting domain names into IP addresses. In this way, allows browsers to access internet resources and websites. IP addresses are actually like site identifiers and other devices can use them to find your system location.

Prerequisite

– A Dedicated Server (We recommend you visit the Cheap Dedicated Server plans presented on our website and choose a plan.)

– Install cPanel on Dedicated Server

Buying Cpanel License is easy. Cpanel has a graphical interface and it is like you can manage your server even with little information as a beginner. Of course, you should have some knowledge to control and make changes to this control panel. Because, if you do not master what you are doing, then will disrupt the performance of your server.

How to Add a New DNS Zone with WHM on Dedicated Server

Actually, if you have a least Cpanel license, the process of adding a DNS zone is simple and easy. So as the first step, login WHM and follow the direction below:

Go to the DNS functions > Add a DNS Zone

Then go through the following steps to add a new DNS zone:

1- You should go to the Domain selection part and as you see the IP field enter the IP address.

2- Now you see the domain field. Enter your domain name.

3- At last click the add zone Button, and add a new zone on your server.

The Way to Edit an Existing Zone

In this way, again you should log in to WHM and find the Edit DNS Zone option:

Here, you will see the Choose a zone to edit option. In the box, type the domain name of your DNS zone to edit and then click the Edit button to start:

If you want to edit a zone, you should have basic information about your preferred parameters to change. The instructions to apply are from the developers, hosting, and internet service provider. This instruction is based on the model of replacing an entry with the new one.

For any DNS domain, NS and A records are critical. In this way, the nameservers are specific to the IP addresses that the DNS server responds to. Be careful not to change them randomly because if you make a mistake, your site will fail.

Conclusion

Here, we tried to show how you can add a DNS zone with WHM on dedicated server. We did this by using Cpanel. Keep in mind that, if you want to control and manage your WHM server, check to make sure the domain is pointing to your correct server IP.

FAQ

Where is the DNS storage location?
These files are stored on the DNS server and are used by the authoritative name server to perform DNS lookups for the domain.

Is it possible to delete the DNS zone?
Of course. First, select a domain name from the choose zones to delete menu. Then click delete on the next interface to confirm that you wish to delete the selected zone
