Tung mediawiki conf

Instruction

1. Install php: yum install php
2. Install MediaWiki, downloaded size 72M, installed size 209 M: yum install mediawiki
3. Edit MediaWiki's httpd configuration file: /etc/httpd/conf.d/mediawiki.conf. Uncomment the first two Alias lines
4. Restart Apache server: service httpd restart
5. Access http://localhost/wiki from a brower. The welcome page should display.
6. Before clicking the setup link, you need to add context httpd_sys_script_rw_t type to /var/www/wiki/config directory. It allows MediaWiki to read and write files inside config directory. Otherwise, crazy selinux will block the write process, and you will get error message “Can't write config file, aborting”.
   • Add context: semanage fcontext -at httpd_sys_script_rw_t "/var/www/wiki/config(/.*)?"
   • Apply context: restorecon -vRF "/var/www/wiki/config"
