This brief tutorial is going to show students and new users how to install Dotclear on Ubuntu 16.04 / 18.10 and 18.04 LTS.

To get started with installing Dotclear, follow the steps below:

Step 1: Install Nginx HTTP Server

Dotclear requires a web server and Nginx HTTP server is probably the second most popular open source web server available today. To install Nginx server, run the commands below:

sudo apt update
sudo apt install nginx

After installing Nginx, the commands below can be used to stop, start and enable Nginx service to always start up with the server boots.

sudo systemctl stop nginx.service
sudo systemctl start nginx.service
sudo systemctl enable nginx.service

Now that Nginx is installed. to test whether the web server is working, open your browser and browse to the URL below.

http://localhost

If you see the page above, then Nginx is successfully installed.

Step 2: Install MariaDB Database Server

Dotclear also requires a database server to store its content. If you’re looking for a truly open source database server, then MariaDB is a great place to start. To install MariaDB run the commands below:

sudo apt-get install mariadb-server mariadb-client

After installing MariaDB, the commands below can be used to stop, start and enable MariaDB service to always start up when the server boots.

Run these on Ubuntu 16.04 LTS

sudo systemctl stop mysql.service
sudo systemctl start mysql.service
sudo systemctl enable mysql.service

Run these on Ubuntu 18.10 and 18.04 LTS

sudo systemctl stop mariadb.service
sudo systemctl start mariadb.service
sudo systemctl enable mariadb.service

Next, run the commands below to secure the database server with a root password if you were not prompted to do so during the installation.

sudo mysql_secure_installation

When prompted, answer the questions below by following the guide.

Enter current password for root (enter for none): Just press the Enter
Set root password? [Y/n]: Y
New password: Enter password
Re-enter new password: Repeat password
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

Now that MariaDB is installed, to test whether the database server was successfully installed, run the commands below.

sudo mysql -u root -p

type the root password when prompted.

If you see a similar screen as shown above, then the server was successfully installed.

Step 3: Install PHP 7.2-FPM and Related Modules

Dotclear is a PHP based CMS and PHP is required. However, PHP 7.2-FPM may not be available in Ubuntu default repositories. To run PHP 7.2-FPM on Ubuntu 16.04 and previous, you may need to run the commands below:

sudo apt-get install software-properties-common
sudo add-apt-repository ppa:ondrej/php

Then update and upgrade to PHP 7.2-FPM

sudo apt update

Next, run the commands below to install PHP 7.2-FPM and related modules.

sudo apt install php7.2-fpm php7.2-common php7.2-mysql php7.2-gmp php7.2-curl php7.2-intl php7.2-mbstring php7.2-xmlrpc php7.2-gd php7.2-xml php7.2-cli php7.2-zip

After installing PHP 7.2, run the commands below to open PHP default configuration file for Nginx.

sudo nano /etc/php/7.2/fpm/php.ini

The lines below is a good settings for most PHP based CMS. Update the configuration file with these and save.

file_uploads = On
allow_url_fopen = On
short_open_tag = On
memory_limit = 256M
cgi.fix_pathinfo = 0
upload_max_filesize = 100M
max_execution_time = 360
date.timezone = America/Chicago

Everytime you make changes to PHP configuration file, you should also restart Nginx web server. To do so, run the commands below:

sudo systemctl restart nginx.service

Now that PHP is installed, to test whether it’s functioning, create a test file called phpinfo.php in Nginx default root directory. ( /var/www/html/)

sudo nano /var/www/html/phpinfo.php

Then type the content below and save the file.

<?php phpinfo( ); ?>

Next, open your browser and browse to the server’s hostname or IP address followed by phpinfo.php

http://localhost/phpinfo.php

You should see PHP default test page.

Step 4: Create Dotclear CMS Database

Now that you’ve installed all the packages that are required for Dotclear to function, continue below to start configuring the servers. First run the commands below to create a blank Dotclear database.

To logon to MariaDB database server, run the commands below.

sudo mysql -u root -p

Then create a database called dotclear

CREATE DATABASE dotclear;

Create a database user called dotclearuser with a new password

CREATE USER 'dotclearuser'@'localhost' IDENTIFIED BY 'new_password_here';

Then grant the user full access to the database.

GRANT ALL ON dotclear.* TO 'dotclearuser'@'localhost' IDENTIFIED BY 'user_password_here' WITH GRANT OPTION;

Finally, save your changes and exit.

FLUSH PRIVILEGES;
EXIT;

Step 5: Download Dotclear Latest Release

To get Dotclear latest release you may want to go and download from its download page. Or use the commands below to use wget and get it downloaded.

Once downloaded extract the downloaded content into the newly created Dotclear directory.

cd /tmp
wget http://download.dotclear.org/latest.tar.gz
tar xvf latest.tar.gz
sudo mv dotclear /var/www/html/dotclear

Next, run the commands below to set the correct permissions for Dotclear root directory and give Nginx control.

sudo chown -R www-data:www-data /var/www/html/dotclear/
sudo chmod -R 755 /var/www/html/dotclear/

Step 6: Configure Nginx

Finally, configure Nginx site configuration file for Dotclear. This file will control how users access Dotclear content. Run the commands below to create a new configuration file called dotclear

sudo nano /etc/nginx/sites-available/dotclear

Then copy and paste the content below into the file and save it. Replace the highlighted line with your own domain name and directory root location.

server {
    listen 80;
    listen [::]:80;
    root /var/www/html/dotclear;
    index  index.php index.html index.htm;
    server_name  example.com www.example.com;

    client_max_body_size 100M;

     location / {
                root /var/www/html/dotclear;
                if (!-e $request_filename) {
                        rewrite ^/(.*)$ /index.php?q=$1 last;
                }
        }

    location ~ \.php$ {
         include snippets/fastcgi-php.conf;
         fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
         fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
         include fastcgi_params;
    }

     location ^~ /data {
         deny all;
      }
}

Save the file and exit.

Step 7: Enable the Dotclear and Rewrite Module

After configuring the VirtualHost above, enable it by running the commands below

sudo ln -s /etc/nginx/sites-available/dotclear /etc/nginx/sites-enabled/
sudo systemctl restart nginx.service

Then open your browser and browse to the server domain name. You should see Dotclear setup wizard to complete. Please follow the wizard carefully.

http://example.com

Then follow the on-screen instruction to complete the setup. On the first screen, type in the database name, database user and password. and click Continue.
