How To Install Composr CMS on Ubuntu 18.04 LTS

In this tutorial, we will show you how to install Composr CMS on Ubuntu 18.04 LTS. For those of you who didn’t know, For those of you who didn’t know, Composr CMS is an open-source content management system for next-generation websites written in PHP with advanced social, interactive, and dynamic functionality. The installation process is fairly easy and it takes only a couple of minutes.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of Composr CMS on an Ubuntu 18.04 (Bionic Beaver) server.

Prerequisites

• A server running one of the following operating systems: Ubuntu 18.04, 16.04, and any other Debian-based distribution like Linux Mint.
• It’s recommended that you use a fresh OS install to prevent any potential issues.
• SSH access to the server (or just open Terminal if you’re on a desktop).
• A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install Composr CMS on Ubuntu 18.04 LTS Bionic Beaver

Step 1. First, make sure that all your system packages are up-to-date by running the following apt-get commands in the terminal.

sudo apt-get update
sudo apt-get upgrade

Step 2. Install LAMP (Linux, Apache, MariaDB, PHP) server.

A Ubuntu 18.04 LAMP server is required. If you do not have LAMP installed, you can follow our guide here. Also, install all required PHP modules:

apt-get install php7.1-cli php7.1-gd php7.1-opcache php7.1-mysql php7.1-json php7.1-mcrypt php7.1-xml php7.1-curl

Step 3. Installing Composr Cms on Ubuntu 18.04 LTS.

First, download the latest stable version of Composr Cms:

wget http://compo.sr/site/dload.php?id=457 -O composr.zip
mkdir /var/www/html/composr
unzip composr.zip -d /var/www/html/composr

We will need to change some folders permissions:

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

Step 4. Configuring MariaDB for Composr Cms.

By default, MariaDB is not hardened. You can secure MariaDB using the mysql_secure_installation script. You should read and below each step carefully which will set a root password, remove anonymous users, disallow remote root login, and remove the test database and access to secure MariaDB.

mysql_secure_installation

Configure it like this:

- Set root password? [Y/n] y
- Remove anonymous users? [Y/n] y
- Disallow root login remotely? [Y/n] y
- Remove test database and access to it? [Y/n] y
- Reload privilege tables now? [Y/n] y

Next, we will need to log in to the MariaDB console and create a database for the Composr Cms. Run the following command:

mysql -u root -p

This will prompt you for a password, so enter your MariaDB root password and hit Enter. Once you are logged in to your database server you need to create a database for Composr Cms installation:

MariaDB [(none)]> CREATE DATABASE composrdb;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON composrdb.* TO 'composr'@'localhost' IDENTIFIED BY 'your_password' WITH GRANT OPTION;
MariaDB [(none)]> SET @@global.sql_mode= '';
MariaDB [(none)]> FLUSH PRIVILEGES;
MariaDB [(none)]> quit

Step 5. Configuring Apache web server for Composr Cms.

Create a new virtual host directive in Apache. For example, create a new Apache configuration file named ‘composr.conf’ on your virtual server:

sudo a2enmod rewrite
sudo a2ensite composr.conf
touch /etc/apache2/sites-available/composr.conf
ln -s /etc/apache2/sites-available/composr.conf /etc/apache2/sites-enabled/composr.conf
nano /etc/apache2/sites-available/composr.conf

Add the following lines:

<VirtualHost *:80>
ServerAdmin admin@yourdomain.com
DocumentRoot /var/www/html/composr
ServerName your-domain.com
ServerAlias www.your-domain.com
<Directory /var/www/html/composr/>
Options FollowSymLinks
AllowOverride All
Order allow,deny
allow from all
</Directory>
ErrorLog /var/log/apache2/your-domain.com-error_log
CustomLog /var/log/apache2/your-domain.com-access_log common
</VirtualHost>

Now, we can restart the Apache webserver so that the changes take place:

systemctl restart apache2.service

Step 6. Accessing Composr CMS.

Composr CMS will be available on HTTP port 80 by default. Open your favorite browser and navigate to http://your-domain.com/install.php or http://server-ip/install.php and complete the required steps to finish the installation. If you are using a firewall, please open port 80 to enable access to the control panel.
