How to Install Openfire on Fedora CoreOS Latest

Openfire is a free and open-source real-time collaboration server based on the XMPP (Jabber) protocol. It can be used for instant messaging, group chat, voice and video calls, and online collaboration. In this tutorial, we will show you how to install Openfire on Fedora CoreOS Latest.

Prerequisites

Before you begin, you'll need the following:

  • A server running Fedora CoreOS Latest.
  • An SSH client such as PuTTY (if you're using Windows).
  • A user account with sudo privileges.

Step 1: Update the System

Before installing any new package, it is always recommended to update the system packages to their latest versions. You can do this by running the following commands:

sudo dnf update

Step 2: Install Java

Openfire is a Java-based application, so you'll need to install Java on your server. Run the following command to install the latest version of OpenJDK:

sudo dnf install java-latest-openjdk

Verify that Java is installed by running the following command:

java -version

You should see output similar to the following:

openjdk version "1.8.0_312"
OpenJDK Runtime Environment (build 1.8.0_312-b07)
OpenJDK 64-Bit Server VM (build 25.312-b07, mixed mode)

Step 3: Download and Extract Openfire

Download the latest version of Openfire by visiting the following URL:

cd /tmp
curl -O https://www.igniterealtime.org/downloadServlet?filename=openfire/openfire-latest.tar.gz

Once the download is complete, extract the archive:

tar -xvf openfire-latest.tar.gz

This will create a new directory named openfire in the current directory.

Step 4: Move the Openfire Directory

To make Openfire available system-wide, move the openfire directory to the /opt directory:

sudo mv openfire /opt/

Step 5: Configure Firewalld

By default, Openfire runs on port 5222 (XMPP client connection) and 9090 (admin console HTTP port). To allow traffic on these ports, add them to the Firewalld firewall rules:

sudo firewall-cmd --add-port=5222/tcp --permanent
sudo firewall-cmd --add-port=9090/tcp --permanent
sudo firewall-cmd --reload

Step 6: Start Openfire

Start the Openfire service by running the following command:

sudo /opt/openfire/bin/openfire start

You can access the Openfire web console by navigating to http://<server-ip>:9090 in your web browser. You should see the following welcome screen:

Openfire welcome screen

Click the "Continue" button to proceed to the setup wizard.

Step 7: Setup Openfire

Follow the steps in the setup wizard to configure Openfire. You'll need to provide information such as the default language, database settings, administrator email address, and server name. Once you've entered all of the required information, click the "Continue" button to proceed.

Once the setup is complete, you'll be redirected to the Openfire admin console login page. Use the administrator username and password you created during the setup process to log in.

Step 8: Autostart Openfire

To ensure that Openfire automatically starts when your server boots up, create a new systemd service file:

sudo nano /etc/systemd/system/openfire.service

Add the following contents to the file:

[Unit]
Description=Openfire XMPP server
After=network.target

[Service]
Type=forking
ExecStart=/opt/openfire/bin/openfire start
ExecStop=/opt/openfire/bin/openfire stop
User=YOUR_USER
Group=YOUR_GROUP

[Install]
WantedBy=multi-user.target

Replace YOUR_USER and YOUR_GROUP with your own user and group names. Save and exit the file.

Now, reload the systemd daemon to pick up the new service file:

sudo systemctl daemon-reload

Enable the Openfire service to autostart on boot:

sudo systemctl enable openfire

Now, you can start, stop, and restart Openfire like any other systemd service:

sudo systemctl start openfire
sudo systemctl stop openfire
sudo systemctl restart openfire

Congratulations! You've successfully installed and configured Openfire on Fedora CoreOS Latest. You can now use it to provide real-time messaging and collaboration services to your users.
