Installing MediaWiki on Ubuntu 23.10

Hello,

In this week’s feature highlight, we look at How to Install MediaWiki on Ubuntu 23.10

MediaWiki is the free open-source wiki software used to power Wikipedia and thousands of other wikis. The contributions of hundreds of individual developers have helped make it a feature-rich, secure and scalable platform capable of powering some of the largest collaboratively edited reference projects in the world.

Update the System

apt update -y

apt upgrade -y 

Install LAMP Stack

Install Linux(Apache, PHP, and MySQL) on system using below command,

apt-get install apache2 mariadb-server php php-mysql libapache2-mod-php php-xml php-mbstring php-intl

Once the installation is complete, enable Apache, (to start automatically upon system boot), start the webserver, and verify the status using the commands below.

systemctl enable apache2

systemctl start apache2 

systemctl status apache2        

also, Enable the MariaDB server using below command,

systemctl enable mariadb

systemctl start mariadb

systemctl status mariadb

Download the MediaWiki

Check out MediaWiki’s Official Site to download the latest version,

cd /tmp/

wget https://releases.wikimedia.org/mediawiki/1.40/mediawiki-1.40.1.tar.gz

Extract the file in your Web Directory,

tar -xvzf /tmp/mediawiki-*.tar.gz

mkdir /var/lib/mediawiki

mv mediawiki-*/* /var/lib/mediawiki

Configuring Apache vHost

Now, create a new Apache configuration file dev.domainhere.info.conf for MediaWiki with the following command.

Replace dev.domainhere.info with the domain name of your own for all the below code examples:

vi /etc/apache2/sites-available/dev.domainhere.info.conf

Now, press i to go to INSERT mode and add the following configuration in the dev.domainhere.info.conf file.

<VirtualHost *:80>

    ServerName dev.domainhere.info
    ServerAlias dev.domainhere.info
    ServerAdmin admin@dev.domainhere.info
    DocumentRoot /var/www/html/mediawiki

    ErrorLog ${APACHE_LOG_DIR}/dev.domainhere.info_error.log
    CustomLog ${APACHE_LOG_DIR}/dev.domainhere.info_access.log combined

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

</VirtualHost>

Enable SSL and Rewrite:

a2enmod rewrite

a2ensite dev.domainhere.info

a2enmod rewrite ssl

Restart Apache:

systemctl restart apache2

Enable http and https ( 80/443 )

To enable http and https connection through the firewall, follow the commands:

ufw allow 80/tcp

ufw allow 443/tcp    

Configure MySQL

Create the MySQL user, database using below command,

mysql -u root -p 

CREATE DATABASE my_wiki;

CREATE USER 'mysql_user'@'localhost' IDENTIFIED BY 'Strong_Password';

GRANT ALL ON my_wiki.* TO 'mysql_user'@'localhost';

FLUSH PRIVILEGES;

EXIT

Replace Strong_Password with an actual password.

Configure PHP

Edit the PHP configuration file, php.ini. It is located at /etc/php/8.*/apache2/php.ini, depending on exact version of PHP,

Change the Maximum Upload File Size to 20 M

upload_max_filesize = 20M

To run the PHP script without errors change the Memory Limit to 128M,

memory_limit = 128M

If it is already set to 128M or more, Save the file and exit.

Configure MediaWiki

Create a symlink on /var/lib/mediawiki with the following command,

ln -s /var/lib/mediawiki /var/www/html/mediawiki

It will give you the issue like mbstring and xml are missing even you have to installed them, activate them using below command,

phpenmod mbstring

phpenmod xml

Restart the Apache Service using below command,

systemctl restart apache2.service

Navigate your browser to http://dev.domainhere.info, you’ll get the installation screen like below,
