XWiki is a free and open source wiki software written in Java runs on a servlet container like Tomcat, JBoss etc. XWiki uses databases such as MySQL or PostgreSQL to store its information. XWiki allows us to store structured data and execute the server script within wiki interface. You can host multiple blogs and manage or view your files and folders using XWiki.

XWiki comes with lots of features, some of them are listed below:

  • Supports version control and ACL.
  • Allows you to search the full wiki using wildcards.
  • Easily export wiki pages to PDF, ODT, RTF, XML and HTML.
  • Content organization and content import.
  • Page editing using WYSIWYG editor.

Requirements

  • A server running Ubuntu 16.04.
  • A non-root user with sudo privileges.

Update the System

Before starting, you will need to update the Ubuntu repository to the latest version. You can do this using the following command:

sudo apt-get update -y
sudo apt-get upgrade -y

Once the repository is updated, restart the system to apply all the updates.

Install Java

Xwiki is a Java-based application, so you will need to install Java 8 first. By default Java 8 is not available in the Ubuntu repository. You can install Java 8 by adding the webupd8team PPA repository to your system.

First, add the PPA by running the following command:

sudo add-apt-repository ppa:webupd8team/java

Next, update the repository with the following command:

sudo apt-get update -y

Once the repository is up to date, you can install Java 8 by running the following command:

sudo apt-get install oracle-java8-installer -y

After installing Java, you can check the version of Java with the following command:

java -version

You should see the following output:

Java version "1.8.0_91"
Java(TM) SE Runtime Environment (build 1.8.0_91-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.91-b14, mixed mode)

Download and Install Xwiki

Next, you will need to download the setup file provided by XWiki. You can download it using the following command:

wget http://download.forge.ow2.org/xwiki/xwiki-enterprise-installer-generic-8.1-standard.jar

Once the download is completed, you can install the downloaded package file using the java command as shown below:

sudo java -jar xwiki-enterprise-installer-generic-8.1-standard.jar
