XWiki is a free and open-source advanced wiki software platform written in Java. It runs on servlet containers like JBoss, Tomcat, etc. which uses a database such as MySQL or PostgreSQL to store its information.<\/p>\n<p>We will use a VPS with CentOS 7 but you should be able to install XWiki following this tutorial on all Red hat based Linux distributions. Installing XWiki on CentOS 7 is a fairly easy task and it shouldn\u2019t take more than 20 minutes to finish it.<\/p>\n<p><!--more--><\/p>\n<p>XWiki comes with tons of useful features such as the following:<\/p>\n<ul>\n<li>BLog<\/li>\n<li>Page editing<\/li>\n<li>Content organization<\/li>\n<li>Forums<\/li>\n<li>Create your own applications<\/li>\n<li>File Manager<\/li>\n<li>Tasks<\/li>\n<li>Different translations of the documents<\/li>\n<li>Meetings<\/li>\n<li>Version control<\/li>\n<li>Content imports<br \/>\nand much more\u2026<\/li>\n<\/ul>\n<h2>Log in to your CentOS 7 server<\/h2>\n<p>Log in to your VPS via SSH as a sudo user:<\/p>\n<pre>ssh userame@IP_Address<\/pre>\n<p>Once you are logged in, issue the following commands to make sure all installed packages are up to date:<\/p>\n<pre>sudo yum update<\/pre>\n<h2><span id=\"Install-Java\" class=\"ez-toc-section\"><\/span>Install Java<\/h2>\n<p>XWiki is a Java-based application so the first step is to install Java on your server. Use the following command to install OpenJDK 8 JRE using yum:<\/p>\n<pre>sudo yum install java-1.8.0-openjdk<\/pre>\n<p>Verify the installation by running:<\/p>\n<pre>java -version<\/pre>\n<p>The command above should print something like the following:<\/p>\n<pre>openjdk version \"1.8.0_181\"\r\nOpenJDK Runtime Environment (build 1.8.0_181-b13)\r\nOpenJDK 64-Bit Server VM (build 25.181-b13, mixed mode)\r\n<\/pre>\n<h2><span id=\"2-Download-Tomcat-8\" class=\"ez-toc-section\"><\/span>2.
