I will show you the step-by-step installation of Dotclear on an Ubuntu 18.04 bionic beaver.


  • A server running one of the following operating systems: Ubuntu 18.04, and any other Debian-based distribution like Linux Mint.
  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • An active internet connection. You’ll need an internet connection to download the necessary packages and dependencies for Dotclear.
  • 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 Dotclear 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 update
sudo apt upgrade

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

An 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 php7.2 libapache2-mod-php7.2 php7.2-common php7.2-mbstring php7.2-xmlrpc php7.2-soap php7.2-gd php7.2-xml php7.2-intl php7.2-mysql php7.2-cli php7.2-zip php7.2-curl

Step 3. Installing Dotclear on CentOS.

Download the latest stable version of Dotclear, At the moment of writing this article it is version 2.14.3:

cd /var/www/html

We will need to change some folders permissions:

chown -R www-data:www-data /var/www/html/

Step 4. Configuring MariaDB.

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.


Next, we will need to log in to the MariaDB console and create a database for Dotclear. 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 Dotclear installation:

MariaDB > CREATE DATABASE dotclear;
MariaDB > GRANT ALL PRIVILEGES ON dotclear.* TO dotclearuser@localhost IDENTIFIED BY 'Your_StrongPassword';
MariaDB > \q

Step 5. Configuring Apache.

To create the virtual host configuration file for your domain, run the following command:

nano /etc/apache2/sites-available/

Add the following lines:

<VirtualHost *:80>

DocumentRoot /var/www/html

<Directory /var/www/html>
     Options Indexes FollowSymLinks
     AllowOverride All
     Require all granted

ErrorLog ${APACHE_LOG_DIR}/your_domain.com_error.log 
CustomLog ${APACHE_LOG_DIR}/your_domain.com_access.log combined 

Save and close the file. We now need to enable the Virtual host configuration file. To enable the Virtual host, run the following command:

ln -s /etc/apache2/sites-available/ /etc/apache2/sites-enabled/

Step 5. Accessing Dotclear.

Dotclear will be available on HTTP port 80 by default. Open your favorite browser and navigate to:
