MediaWiki is a free software open source wiki package written in PHP, originally for use on Wikipedia.The software is optimized to correctly and efficiently handle projects of all sizes, including the largest wikis, which can have terabytes of content and hundreds of thousands of hits per second.Because Wikipedia is one of the world's largest websites, achieving scalability through multiple layers of caching and database replication has also been a major concern for developers. Wikipedia and other Wikimedia projects continue to define a large part of the requirement set for MediaWiki. I'm describing about the installation of mediawiki on a CentOS server.
Download mediawiki into /usr/local/src
Extract mediawiki and move into DocumentRoot
#tar xvzf mediawiki-1.22.3.tar.gz
#mv mediawiki-1.22.3 /var/www/html/mediawiki
Create Database and User in mysql
Enter into mysql as root
You need to enter mysql root password to enter in to mysql.
#mysql -u root -p
You will get mysql command terminal.We need to create Database, User for mediawiki.
I'm going to set database name, username , and password as 'mediawiki'.You can change it as per your wish.
mysql> create database mediawiki;
mysql> create user mediawiki@localhost;
Set password for mysql user
mysql> set password for mediawiki@localhost = password ('mediawiki');
Allow Grant privileges to the user
mysql>GRANT ALL PRIVILEGES ON mediawiki.* to mediawiki@localhost identified by 'mediawiki';
mysql> flush privileges;
Now all the Activities in mysql is completed.You can simply logout from the mysql using quit
Set Ownership and permission in DocumentRoot
We need to set the Owner and group of mediawiki as apache.Set 755 permission to the /var/www/html/mediawiki folder
#chown -R apache:apache /var/www/html/mediawiki
#chmod -R 755 /var/www /html/mediawiki
Installation of mediawiki from the browser.
