How to Install RainLoop on Debian 11

It’s better to check your Debian version with the help of the following command:

lsb_release -ds

Now update your system by entering the following command:

apt update

apt upgrade -y

Then you should install the necessary packages by running the following command:

apt install -y sudo dirmngr wget curl vim

You can create a non-root user account with sudo access by executing the following command:

adduser lindaevanty --gecos "Linda Evanty"
usermod -aG sudo lindaevanty
su - lindaevanty

Tip: Remember to replace your username with “lindaevanty”.

Now you should setup the timezone by executing the following command:

sudo dpkg-reconfigure tzdata

In this step, you should download and install PHP and the necessary extensions by entering the following command:

sudo apt install -y php7.0 php7.0-cli php7.0-fpm php7.0-curl php7.0-json php7.0-mbstring php7.0-mysql php7.0-pgsql php7.0-sqlite3 php7.0-common php7.0-xml

To check the PHP version just run the following command:

php --version

In this step, you can install MariaDB by executing the following command:

sudo apt install -y mariadb-server

To check the MariaDB version just enter the following command:

mysql --version

You can run the following command to improve the security of the MariaDB installation:

sudo mysql_secure_installation

Then you should log into MariaDB as the root user by entering the following command:

sudo mysql -u root -p
# Enter password:

Now you should create a MariaDB database by executing the following command:

CREATE DATABASE dbname;

Then you need to create a MariaDB user. To do this just enter the following command:

CREATE USER 'username'@'localhost' IDENTIFIED BY 'password';
GRANT ALL ON 'dbname'.*TO 'username'@'localhost';
FLUSH PRIVILEGES;
EXIT;

Next, you need to install Nginx using the following command:

sudo apt install -y nginx

You can check the Nginx version by executing the following command:

sudo nginx -v

Now you should configure Nginx for RainLoop. To do this first enter the following command:

sudo vim /etc/nginx/sites-available/rainloop.conf

And then enter the following configuration:

server {

  listen 80;

  server_name example.com;
  root /var/www/rainloop;

  index index.php;

  location / {
    try_files $uri $uri/ /index.php?$query_string;
  }

  location ~ \.php$ {
    fastcgi_index index.php;
    fastcgi_split_path_info ^(.+\.php)(.*)$;
    fastcgi_keep_conn on;
    include fastcgi_params;
    fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
  }

  location ~ /\.ht {
    deny all;
  }

  location ^~ /data {
     deny all;
  }

}

Now you need to activate the new rainloop.conf configuration. To do this link the file to the sites-enabled directory:

sudo ln -s /etc/nginx/sites-available/rainloop.conf /etc/nginx/sites-enabled

You can test the configuration with the help of the following command:

sudo nginx -t

Finally, reload Nginx with the following command:

sudo systemctl reload nginx.service

You need to create a document root directory before downloading Rainloop:

sudo mkdir -p /var/www/rainloop

Then you should change the ownership of the /var/www/rainloop directory to your name as shown below:

sudo chown -R lindaevanty:lindaevanty /var/www/rainloop

If you do not have the unzip app, you can install it with the following command:

sudo apt install -y unzip

Now it’s time to download Rainloop. To do this, just run the following command:

cd /var/www/rainloop
wget http://www.rainloop.net/repository/webmail/rainloop-latest.zip

Then you should unzip it with the following command:

unzip rainloop-latest.zip -d /var/www/rainloop
rm rainloop-latest.zip

Finally, you have to change the ownership of the /var/www/rainloop directory to www-data:

sudo chown -R www-data:www-data /var/www/rainloop
