In this tutorial, you will learn how to install Openfire, a real-time collaboration server, on Alpine Linux Latest.
Before we begin, you need:
It is always a good practice to update the system before installing any new software. Use the following command to update your system:
sudo apk update && sudo apk upgrade
Openfire requires Java 8 or later to run. To install OpenJDK on Alpine Linux, run the following command:
sudo apk add openjdk8
Use wget to download the Openfire tarball from the official website:
sudo wget https://www.igniterealtime.org/downloadServlet?filename=openfire/openfire-4.6.4.tar.gz -O openfire-4.6.4.tar.gz
After the download is complete, extract the tarball to the /opt directory:
sudo tar zxvf openfire-4.6.4.tar.gz -C /opt
Create a new user and group for Openfire to run under:
sudo addgroup -S openfire
sudo adduser -S -G openfire openfire
Change the ownership of the Openfire directory to the openfire user and group:
sudo chown -R openfire:openfire /opt/openfire
To start the Openfire server, run the following command:
sudo su - openfire -s /bin/sh -c "/opt/openfire/bin/openfire start"
The Openfire server should now be running.
Configure firewall rules to allow external clients to connect to the Openfire server. Openfire uses port 5222 for client-to-server communication and port 5269 for server-to-server communication.
If you are using the default firewall on Alpine Linux, run the following commands:
sudo iptables -A INPUT -p tcp --dport 5222 -j ACCEPT
sudo iptables -A INPUT -p tcp --dport 5269 -j ACCEPT
In this tutorial, you learned how to install Openfire on Alpine Linux Latest. You also learned how to configure the firewall rules to allow external clients to connect to the Openfire server.
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!
