How to Install XWiki on Arch Linux

XWiki is an open-source software platform that allows users to create and share collaborative content. This tutorial will guide you through the process of installing XWiki on Arch Linux.

Prerequisites

Before we begin, make sure you have the following prerequisites:

• A server running Arch Linux
• Root access to the server
• Basic knowledge of Linux commands and shell

Step 1: Install Java

XWiki requires Java to run. Install the latest version of Java using the following command:

sudo pacman -S jre-openjdk

Step 2: Install a Database

Next, you need to install a database. XWiki supports several databases, including MySQL and PostgreSQL. In this tutorial, we will use PostgreSQL.

Install the PostgreSQL database using the following command:

sudo pacman -S postgresql

Once installed, initialize the database:

sudo -u postgres initdb --locale $LANG -E UTF8 -D '/var/lib/postgres/data'

Finally, start the PostgreSQL service:

sudo systemctl start postgresql

Step 3: Install XWiki

With the prerequisites out of the way, let's install XWiki:

1. Download and extract the XWiki software:

   wget https://dl.xwiki.com/xwiki/download/releases/xwiki-enterprise-<version>.zip
   unzip xwiki-enterprise-<version>.zip
   

2. Move the extracted directory to /opt:

   sudo mv xwiki-enterprise-<version> /opt
   

3. Add a dedicated user for XWiki:

   sudo useradd xwiki -d /opt/xwiki
   

4. Change the ownership of the XWiki directory to the new user:

   sudo chown -R xwiki:xwiki /opt/xwiki
   

5. Create a symlink to the XWiki directory:

   sudo ln -s /opt/xwiki/xwiki-enterprise-<version> /opt/xwiki/current
   

Step 4: Configure XWiki

Now that XWiki is installed, let's configure it:

1. Create a new PostgreSQL user and database for XWiki:

   sudo -u postgres createuser xwiki
   sudo -u postgres createdb -O xwiki xwikidb
   

2. Copy the hibernate.cfg.xml file to XWiki's configuration directory:

   sudo cp /opt/xwiki/current/WEB-INF/hibernate.cfg.xml /opt/xwiki/current/WEB-INF/hibernate.cfg.xml.original
   sudo cp /opt/xwiki/current/WEB-INF/hibernate.cfg.xml.postgres /opt/xwiki/current/WEB-INF/hibernate.cfg.xml
   

3. Edit the hibernate.cfg.xml file and enter the PostgreSQL database details:

   sudo nano /opt/xwiki/current/WEB-INF/hibernate.cfg.xml
   

   Replace <USER> and <PASSWORD> with the PostgreSQL user and password you created earlier.

4. Start XWiki:

   sudo -u xwiki /opt/xwiki/current/startup.sh
   

   Wait for XWiki to start up. You may see a message in the console that says Tomcat started.

5. Access XWiki from a web browser:

   Navigate to http://<server-ip>:8080/xwiki/ in your web browser to access XWiki.

   Note: By default, XWiki runs on port 8080. If you wish to change the port, edit the server.xml file located at /opt/xwiki/current/jetty/

Conclusion

Congratulations! You have installed XWiki on Arch Linux. You can now create and share collaborative content using XWiki.

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!

Alternatively, for the best virtual desktop, try Shells!
