Installing Openfire on Ubuntu 18.04 | Ubuntu 16.04

Installation of Openfire on Ubuntu 18.04 is a pretty straightforward process. Follow steps below to have Openfire installed and configured on your system.

Step 1: Update system packages:

Ensure all packages on your Ubuntu 18.04 system are up to date:

sudo apt-get update
sudo apt-get upgrade

Step 2: Install JAVA JDK

Once the packages are updated, install openjdk-8-jdk or 9 if you wish. openjdk-8-jdk package is available on Ubuntu official repositories. Installing by running the command:

$ sudo apt-get install openjdk-8-jdk
$ java -version
openjdk version "1.8.0_171"
OpenJDK Runtime Environment (build 1.8.0_171-8u171-b11-0ubuntu0.18.04.1-b11)
OpenJDK 64-Bit Server VM (build 25.171-b11, mixed mode)

Step 3: Install MySQL/MariaDB or PostgreSQL Database server

You can choose a database from supported database servers. For this setup, we’ll Install  MariaDB or MySQL.

sudo apt install mariadb-server

Create database user:

Create database for openfire:

$ sudo mysql -u root
CREATE DATABASE openfire;
GRANT ALL PRIVILEGES ON openfire.* TO openfire@localhost IDENTIFIED BY 'StrongP@ssword123!';
FLUSH PRIVILEGES;
QUIT

Later we will import Openfire database data.

Step 4: Download and Install Openfire

Download Openfire package. You can get the latest version from the Download link. As of this writing, the latest version is Openfire 4.5.2.

wget https://www.igniterealtime.org/downloadServlet?filename=openfire/openfire_4.5.2_all.deb -O openfire.deb

Let’s now install it:

sudo  dpkg -i openfire.deb 

Check application status:

$ systemctl status openfire

Import Openfire database schema:

$ mysql -u root -p
Enter password:

mysql> use openfire;
Database changed
mysql> source /usr/share/openfire/resources/database/openfire_mysql.sql;
mysql> show tables;

Step 5: Configure Firewall and Access Openfire UI

If you have an active firewall service, you need to allow ports for Openfire. My Ubuntu 18.04 system runs ufw:

$ sudo ufw enable
$ for i in 9090 9091 5222 7777; do 
sudo ufw allow $i; done

To access GUI, you’ll use Server’s ip address and the port 9090:

http://<server-ip|domain>:9090

You will get Openfire configuration window:

Select your default language then click Continue.  On Server setup window, set your domain and click Continue button.

We’ll use the following Configuration Parameters.
Database Driver Presets:MySQL
JDBC Driver Class: com.mysql.jdbc.Driver
Database URL:jdbc:mysql://127.0.0.1/openfire?useUnicode=true&characterEncoding=UTF-8&characterSetResults=UTF-8
Username: openfire
Password: password123!

Click Continue and use Default option on Profile Settings; You can later add external authentication mechanisms like LDAP

Set admin user email address and password:

Click Continue to finish configuration. You’ll get a login page, login with admin as username and provide password  configured above.

If everything went well, you should get Openfire Management interface:
