In this tutorial, we will show you how to install Friendica with Apache and Let's Encrypt SSL on Ubuntu 20.04.

Prerequisites

A server running Ubuntu 20.04.
A valid domain name pointed with your server IP.
A root password is configured the server.

Getting Started

Before starting, you will need to update your system packages to the latest version. You can update them using the following command:

apt-get update -y

Once your server is updated, you can proceed to the next step.

Install LAMP Server

Friendica runs on webserver, written in PHP and uses MySQL as a database backend. So the LAMP stack must be installed in your system. If not installed, you can install it with the following command:

apt-get install apache2 mariadb-server php libapache2-mod-php php-common php-gmp php-curl php-intl php-mbstring php-xmlrpc php-mysql php-gd php-imagick php-xml php-cli php-zip php-sqlite3 curl git -y

Once all the packages are installed, edit the php.ini file and make some changes:

nano /etc/php/7.4/apache2/php.ini

Change the following lines:

memory_limit = 256M
upload_max_filesize = 100M
max_execution_time = 300
max_input_vars = 1500
date.timezone = Asia/Kolkata

Save and close the file when you are finished.

Create a Friendica Database

Next, you will need to create a database and user for Friendica. First, connect to the MySQL with the following command:

mysql

Once connected, create a database and user with the following command:

MariaDB [(none)]> CREATE DATABASE friendicadb;
MariaDB [(none)]> CREATE USER 'friendica'@'localhost' IDENTIFIED BY 'password';

Next, grant all the privileges to the Friendica database with the following command:

MariaDB [(none)]> GRANT ALL ON friendicadb.* TO 'friendica'@'localhost' WITH GRANT OPTION;

Next, flush the privileges and exit from the MySQL with the following command:

MariaDB [(none)]> FLUSH PRIVILEGES;
MariaDB [(none)]> EXIT;

Once you are finished, you can proceed to the next step.

Download Friendica

Before downloading Friendica, you will need to install Composer in your system. You can install it with the following command:

apt-get install composer -y

Once installed, change the directory to Apache web root and download the latest version of Friendica from the Git repository:

cd /var/www/html
git clone https://github.com/friendica/friendica.git

Once the download is completed, change the directory to friendica and install the required PHP dependencies with the following command:

cd friendica
composer install --no-dev

Next, download the Friendica addons with the following command:

git clone https://github.com/friendica/friendica-addons.git

Next, set proper ownership and permission to the friendica directory:

chown -R www-data:www-data /var/www/html/friendica/
chmod -R 755 /var/www/html/friendica/

Once you are finished, you can proceed to the next step.

Configure Apache for Friendica

Next, you will need to create an Apache virtual host configuration file to host Friendica. You can create it with the following command:

nano /etc/apache2/sites-available/friendica.conf

Add the following lines:

<VirtualHost *:80>
     ServerAdmin [email protected]
     DocumentRoot /var/www/html/friendica
     ServerName friendica.example.com


     <Directory /var/www/html/friendica/>
        Options +FollowSymlinks
        AllowOverride All
        Require all granted
     </Directory>

     ErrorLog ${APACHE_LOG_DIR}/error.log
     CustomLog ${APACHE_LOG_DIR}/access.log combined

</VirtualHost>

Save and close the file then enable the Apache virtual host and rewrite module with the following command:

a2ensite friendica.conf
a2enmod rewrite

Next, reload the Apache service to apply the changes:

systemctl restart apache2

You can verify the status of the Apache service with the following command:

systemctl status apache2

You should get the following output:

Secure Friendica with Let's Encrypt SSL

apt-get install python3-certbot-apache -y

Once the Certbot is installed, run the following command to secure your website with Let's Encrypt SSL:

certbot --apache -d friendica.example.com
