Dotclear is an open-source web publishing platform for LAMP. This guide explains how to install Dotclear on a Vultr Ubuntu 20.04 cloud server.


Before starting this guide:

You can also use Vultr's Ubuntu 20.04 LAMP Marketplace application.

1. Install Dependencies

  1. SSH to your server and update the package information index.

     $ sudo apt update
  2. Install the required PHP extensions for Dotclear.

     $ sudo apt install libapache2-mod-php
  3. Restart Apache to load the extensions.

     $ sudo systemctl restart apache2

2. Create the Database and User Account

  1. Log in to your database server as root.

    $ sudo mysql -u root -p

  2. Create a dot_clear database and a dot_clear_user account. Replace EXAMPLE_PASSWORD with a strong password.

    If you use MySQL:

     mysql> CREATE DATABASE dot_clear;
            CREATE USER 'dot_clear_user'@'localhost' IDENTIFIED WITH mysql_native_password BY 'EXAMPLE_PASSWORD';
            GRANT ALL PRIVILEGES ON dot_clear.* TO 'dot_clear_user'@'localhost';           

    If you use MariaDB:

     MariaDB> CREATE DATABASE dot_clear;
              GRANT ALL PRIVILEGES on dot_clear.* TO 'dot_clear_user'@'localhost' identified by 'EXAMPLE_PASSWORD';
  3. Exit the database server.

     mysql> QUIT;

3. Create the Directory Structure

  1. Create a dot_clear directory under the web root.

     $ sudo mkdir -p /var/www/dot_clear
  2. Take ownership of the directory.

     $ sudo chown -R $USER:$USER /var/www/dot_clear
  3. Change to the directory.

     $ cd /var/www/dot_clear
  4. Download the installation script.

     $ wget
  5. Change the ownership of the /var/www/dot_clear directory to the Apache user www-data.

     $ sudo chown -R www-data:www-data /var/www/dot_clear

4. Create a Virtual Host File

  1. Disable the default virtual host configuration.

     $ sudo a2dissite 000-default.conf
  2. Create a new virtual host configuration file.

     $ sudo nano /etc/apache2/sites-available/dot_clear.conf
  3. Paste the information below into the file. Replace with your server's public IP address or domain name.

     <VirtualHost *:80>
         DocumentRoot "/var/www/dot_clear"
         <Directory "/var/www/dot_clear">
             Require all granted
             Options Indexes FollowSymLinks
             AllowOverride All
             Order allow,deny
             Allow from all
     ErrorLog ${APACHE_LOG_DIR}/error.log
     CustomLog ${APACHE_LOG_DIR}/access.log combined
  4. Save and exit the file.
