For those of you who didn’t know, MediaWiki is a free and open source wiki software, used to power wiki websites such as Wikipedia, Wiktionary and Commons, developed by the Wikimedia Foundation and others. It is written in the PHP programming language and uses a backend database.
This article assumes you have at least basic knowledge of linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple. I will show you through the step by step installation MediaWiki on CentOS 7.
Step 1. First of all make sure that all packages are up to date.
yum -y update
Step 2. Install LAMP server and include some PHP extension.
yum install mariadb mariadb-server httpd php-common php-xml php-intl php-gd texlive
Start service Apache web server and MariaDB also enable it to start on boot of the server:
systemctl start httpd
systemctl start mariadb
systemctl enable httpd
systemctl enable mariadb
Step 3. Configuring MariaDB for MediaWiki.
By default, MariaDB is not hardened. You can secure MariaDB using the mysql_secure_installation script. you should read and below each steps carefully which will set 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 MediaWiki. 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 the MediaWiki software:
MariaDB > create database mediawiki;
MariaDB > grant all privileges on mediawiki.* to mwuser@localhost identified by 'your_password';
MariaDB > > flush privileges;
MariaDB > quit;
Step 4. Install MediaWiki.
Download the latest stable version of MediaWiki, At the moment of writing this article it is version 1.25.1:
tar xvzf mediawiki-*.tar.gz
mv mediawiki-1.25.1/* /var/www/html/
We will need to change some folders permissions:
chown -R apache:apache /var/www/html
chmod -R 755 /var/www/html
Restart the Apache service for the changes to take effect:
systemctl restart httpd
Step 6. Accessing MediaWiki.
MediaWiki will be available on HTTP port 80 by default. Open your favorite browser and navigate to http://yourdomain.com or http://server-ip and complete the required the steps to finish the installation. If you are using a firewall, please open port 80 to enable access to the control panel.
At the end of the installation, you will need to upload the file to /var/www/html. You can do that via FTP, but to speed up the process, just open the downloaded file with a text editor, copy all the content from it and paste it to a new LocalSettings.php file that you can create using the following command:
Congratulation’s! You have successfully installed MediaWiki. Thanks for using this tutorial for installing MediaWiki on CentOS 7 system.
