MediaWiki is a free open source wiki software which is written in PHP and allows everyone to create their own wiki sites.

1. Install operating system packages

# dnf install httpd php php-mysqlnd php-gd php-xml mariadb-server mariadb php-mbstring php-json

2. Database configuration

# systemctl start mariadb
# systemctl enable mariadb

Secure MariaDB and log in to it:

# mysql_secure_installation
# mysql -u root -p

Create the database and database user:

> CREATE DATABASE wiki_database; 
> CREATE USER 'wiki_user'@'localhost' IDENTIFIED BY 'PASSWORD';

Grant privileges to newly created DB:

>GRANT ALL PRIVILEGES ON wiki_database.* TO 'wiki_user'@'localhost';
> FLUSH PRIVILEGES;

3. Apache configuration

Create a virtual host

# cd /etc/httpd/conf.d
# nano domain.conf
<VirtualHost *:80>
ServerName www.domain.name
DocumentRoot /var/www/domain.name/www
ServerAlias domain.name
ErrorLog /var/www/domain.name/error.log
CustomLog /var/www/domain.name/requests.log combined
</VirtualHost>

Start Apache and enable it so that will automatically start after a reboot

# systemctl start httpd
# systemctl enable httpd

Create a folder document root where files will be stored.

# mkdir -p /var/www/domain.name/www

Grant permissions

# chown -R apache: /var/www/domain.name
