Installing XWiki on Elementary OS

XWiki is a powerful open-source enterprise wiki platform that lets you create, manage, and share wiki pages and applications. In this tutorial, we will guide you through the steps of installing XWiki on Elementary OS Latest.

Prerequisites

Before we start with the installation process, make sure that you have the following:

• A user account with sudo privileges
• Java 8 or higher
• MySQL or PostgreSQL database server
• Apache Tomcat or another servlet container

Step 1: Install Java

XWiki requires Java to run. If you don't have Java installed on your system, execute the following command to install the default version of Java:

sudo apt-get install default-jdk

Step 2: Install and configure the database server

XWiki requires a database server to store data. You can choose between MySQL or PostgreSQL. In this tutorial, we will be using MySQL.

Install MySQL

You can install MySQL from the default repository using the following command:

sudo apt-get install mysql-server

Configure MySQL

Once MySQL is installed, you'll need to create a database and a user for XWiki:

1. Log in to the MySQL shell as the root user:

   sudo mysql -u root
   

2. Create a database for XWiki. Replace xwiki_db with the name of your choice:

   CREATE DATABASE xwiki_db;
   

3. Create a user and grant them privileges for the new database. Replace xwiki_user and xwiki_password with your preferred credentials:

   CREATE USER 'xwiki_user'@'localhost' IDENTIFIED BY 'xwiki_password';
   GRANT ALL PRIVILEGES ON xwiki_db.* TO 'xwiki_user'@'localhost' WITH GRANT OPTION;
   

4. Exit the MySQL shell:

   EXIT;
   

Step 3: Install and configure Apache Tomcat

Apache Tomcat is a widely used servlet container that can be used to deploy Java web applications like XWiki.

Install Apache Tomcat

You can install Apache Tomcat from the default repository using the following command:

sudo apt-get install tomcat9

Configure Apache Tomcat

Once Tomcat is installed, you'll need to modify some configuration files to make XWiki work properly:

1. Open the Tomcat configuration file:

   sudo nano /etc/tomcat9/server.xml
   

2. Add the following lines inside the <Host> element:

   <Context path="/xwiki" docBase="/usr/share/xwiki" unpackWAR="false" />
   <Valve className="org.apache.catalina.valves.RemoteIpValve" protocolHeader="X-Forwarded-Proto" />
   

3. Save and close the file.

Step 4: Download and install XWiki

You can download the latest version of XWiki from the official website: https://www.xwiki.org/xwiki/bin/view/Main/Download

Once you have downloaded the xwiki-web-*.war file, move it to the Tomcat webapps directory:

sudo mv xwiki-web-*.war /var/lib/tomcat9/webapps/xwiki.war

Restart the Tomcat service to apply the changes:

sudo systemctl restart tomcat9

Step 5: Launch XWiki

Open a web browser and navigate to http://localhost:8080/xwiki. The XWiki installation wizard should start automatically.

Follow the instructions to complete the installation process.

Congratulations! You have successfully installed XWiki on Elementary OS Latest.
