How to Install PmWiki on CentOS 6.x

PmWiki is a free and an open source wiki application that is  lightweight. PmWiki was at first release in 2004. PmWiki is a wiki-based system for collaborative creation and maintenance of websites. The web-pages created using PmWiki looks like normal web pages, but they also have the edit link to modify existing pages and add new pages in the website.

In this article I will show you how to install PmWiki on CentOS 6.x system.

Features

• Custom look-and-feel: A site administrator can quickly change the appearance and functions of a PmWiki site by using different skins and HTML templates. If you can’t find an appropriate skin already made, you can easily modify one or create your own.
• Access control: PmWiki password protection can be applied to an entire site, to groups of pages, or to individual pages. Password protection controls who can read pages, edit pages, and upload attachments. PmWiki’s access control system is completely self-contained, but it can also work in conjunction with existing password databases, such as .htaccess, LDAP servers, and MySQL databases.
• Customization and plugin architecture: One principle of the PmWikiPhilosophy is to only include essential features in the core engine, but make it easy for administrators to customize and add new markup. Hundreds of features are already available by using extensions (called “recipes”) that are available from the PmWiki Cookbook. -PmWiki developer

Prerequisites

• LAMP Stack should be installed on the system.
