How to Install and Configure Mediawiki on Ubuntu-16.04

Introduction

Mediawiki is a free and open source software package written in PHP, developed by the Wikimedia Foundation. Mediawiki runs on many websites such as Wikipedia, Wiktionary and Wikimedia Commons. Mediawiki also known as a wiki engine is software that allows users to create and edit pages via a web browser.

In this tutorial, we will learn how to install and configure Mediawiki on Ubuntu-16.04 server.

Requirements

  • A server runing Ubuntu-16.04.
  • A non-root user with sudo privileges setup on your server.

Getting Started

Before starting, update your system with the following command:

sudo apt-get update -y sudo apt-get upgrade -y

Once system is up-to-date, you will need to install LAMP stack on your server.

You can install it with the following command:

sudo apt-get install apache2 mariadb-server php7.0-mysql php-xml php7.0-curl php7.0-json php7.0-cgi php7.0 libapache2-mod-php7.0 imagemagick php7.0-intl php7.0-gd php7.0-mbstring

Once installation is complete, you will need to enable Apache rewrite module.

You can do this by running the following command:

sudo a2enmod rewrite

Now, restart the Apache service for the changes to take effect:

sudo systemctl restart apache2

Installing Mediawiki

Before starting, you will need to download the latest version of Mediawiki from https://www.mediawiki.org/wiki/Download.

You can download Mediawiki using wget command as follows:

cd /opt/ sudo wget https://releases.wikimedia.org/mediawiki/1.27/mediawiki-1.27.1.tar.gz sudo tar -xvzf mediawiki-1.27.1.tar.gz

Next, move mediawiki-1.27.1 to Apache document root directory:

sudo mv /opt/mediawiki-1.27.1 /var/www/html/mediawiki

Change the ownership of mediawiki directory to www-data:

sudo www-data:www-data -R /var/www/html/mediawiki

Configuring the Database

Default Mariadb installation is not secure, so you will need to secure it first. You can secure it using mysql_secure_installation script:

sudo mysql_secure_installation

Answer all the questions as follows:

    NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
          SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we'll need the current password for the root user. If you've just installed MariaDB, and you haven't set the root password yet, the password will be blank, so you should just press enter here.

Enter current password for root (enter for none): OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MariaDB root user without the proper authorisation.

You already have a root password set, so you can safely answer 'n'.

Change the root password? [Y/n] n ... skipping.

By default, a MariaDB installation has an anonymous user, allowing anyone to log into MariaDB without having to have a user account created for them. This is intended only for testing, and to make the installation go a bit smoother. You should remove them before moving into a production environment.

Remove anonymous users? [Y/n] Y

Normally, root should only be allowed to connect from 'localhost'. This ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] Y ... Success!

By default, MariaDB comes with a database named 'test' that anyone can access. This is also intended only for testing, and should be removed before moving into a production environment.

Remove test database and access to it? [Y/n] Y - Dropping test database... ... Success! - Removing privileges on test database... ... Success!

Reloading the privilege tables will ensure that all changes made so far will take effect immediately.

Reload privilege tables now? [Y/n] Y ... Success!

Cleaning up...

All done! If you've completed all of the above steps, your MariaDB installation should now be secure.

Thanks for using MariaDB!

Next, you will need to login MariaDB console and create a Database for the Mediawiki. You can do this by running the following command:

mysql -u root -p

Enter the password for root user, you should see the following output:

    Welcome to the MariaDB monitor.  Commands end with ; or g.
    Your MariaDB connection id is 106
    Server version: 10.0.27-MariaDB-0ubuntu0.16.04.1 Ubuntu 16.04

Copyright (c) 2000, 2016, Oracle, MariaDB Corporation Ab and others.

Type 'help;' or 'h' for help. Type 'c' to clear the current input statement.

MariaDB [(none)]>

Once you are logged in to MariaDB console, create a database and user with the following command:

MariaDB [(none)]> CREATE DATABASE mediawikidb;
    Query OK, 1 row affected (0.00 sec)
MariaDB [(none)]> CREATE USER 'user'@'localhost' IDENTIFIED BY 'password';
    Query OK, 0 rows affected (0.06 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON wikidb.* TO 'user'@'localhost';
    Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.01 sec)
MariaDB [(none)]> exit

Configure Apache for Mediawiki

Once database is configured, you will need to configure Apache for Mediawiki. So, you will need to create new virtual host file for Mediawiki:

sudo nano /etc/apache2/sites-available/mediawiki.conf

Add the following lines:


ServerAdmin admin@yourdomain.com DocumentRoot /var/www/html/mediawiki/ ServerName 192.168.15.189

Options FollowSymLinks AllowOverride All Order allow,deny allow from all

ErrorLog /var/log/apache2/mediawiki-error_log CustomLog /var/log/apache2/mediawiki-access_log common

Save and close the file when you are finished.

Next, you will need to enable mediawiki site and disable 000-default site.

You can do this by running the following command:

sudo a2ensite mediawiki sudo a2dissite 000-default

Next, reload apache service with the following command:

systemctl restart apache2

Accessing Mediawiki

Once everything is setup properly, it's time to access Mediawiki.

Open your favourite web browser and type the URL http://your-server-ip, and hit Enter button, you should see the following page:

Next, click on the set up the wiki hyperlink and follow the instructions on the screen and fill up the necessary information as required.

Select your language and the Wiki language. On the next page, click continue , then enter the following information:

    Database Host: localhost
    Database name: mediawikidb
    Database username: user
    Database password: password

Next, click on the Continue, and select:

    Storage engine: InnoDB
    Database character set: UTF-8

Next, click on Continue and enter the name of Wiki which will appear in the title bar of the web browser and other places, create an administrator account and install the Wiki.

The configuration process will prompt you to download a LocalSettings.php, so download it and save it to /var/www/html/mediawiki directory.

Also, if you want to improve the speed and performance of your MediaWiki installation, add the following lines at the end of the LocalSettings.php file :

sudo /var/www/html/mediawiki/LocalSettings.php

Add the following lines:

    # Speed improvements
    $wgUseGzip = true;
    $wgUseFileCache = true;

# Performance settings $wgDisableCounters = true; $wgMiserMode = true;

Once you are finished, open your web browser and type the URL http://your-server-ip to see your new wiki:

Conclusion

Congratulations! You have successfully installed MediaWiki on your Ubuntu-16.04 server. You can now easily create your own wiki page using Mediawiki.
