Openfire is an open source real-time collaboration (instant messaging) server, built on the XMPP protocol and available for multiple platforms. This guide will help you get started with Openfire on your Debian 6 (Squeeze) Linux VPS.
If you haven't done so already, please follow the steps outlined in our getting started guide before following these instructions, and make sure your system is fully updated. Initial configuration steps will be performed through the terminal; please make sure you're logged into your Linode as root via SSH.
Before you begin installing and configuring the components described in this guide, please make sure you've followed our instructions for setting your hostname. Issue the following commands to make sure it is set properly:
hostname hostname -f
The first command should show your short hostname, and the second should show your fully qualified domain name (FQDN).
Openfire requires a Java runtime engine (JRE). This tutorial uses the version provided by Oracle. Please note that although alternate Java runtime engines are available, Openfire may not work well with them.
Examine your /etc/apt/sources.list file to make sure you have the non-free repository enabled. You can use an editor like nano to edit configuration files through the shell; you would issue the command "nano /etc/apt/sources.list" to edit this one. Please consult the nano manual page for information on using the editor. Your file should look similar to the following.
deb http://mirrors.kernel.org/debian/ squeeze main contrib non-free deb-src http://mirrors.kernel.org/debian/ squeeze main contrib non-free deb http://security.debian.org/ squeeze/updates main contrib non-free deb-src http://security.debian.org/ squeeze/updates main contrib non-free
If you had to add the non-free repository to your sources, issue the following command to update your package database:
apt-get update apt-get upgrade
Issue the following command to install prerequisite packages on your server:
apt-get install sun-java6-jre
The Java6 JRE will be installed, along with a series of dependencies it requires. You will be prompted to accept a licensing agreement for before proceeding.
If you employ a firewall to specify what ports can be accessed on your VPS, please make sure you have the following ports open:
Additional ports may need to be opened later to support more advanced XMPP services, but these are the ports that Openfire will use by default.
Visit the download page for the Openfire RTC server and click the link for the Debian package. You will be taken to another page, which will start the download to your workstation. You may cancel this download, as a manual download link will be presented that you may copy to your clipboard. Use wget on your Linode to retrieve the package (substitute the link for the current version in the command below). You may need to install wget first using the command "apt-get install wget".
Install the software using dpkg as follows:
dpkg -i *openfire*.deb
Next, edit the configuration file /etc/openfire/openfire.xml, inserting your Linode's public IP address in the <interface> section, and removing the "<!-- -->" comment markers that surround this section.
Restart Openfire with the following command:
This completes the initial installation steps for Openfire. Next, we'll continue with configuration through a web browser.
Before proceeding, reboot your Linode. Once it has come back online, direct your browser to its IP address or FQDN (fully qualified domain name, if an entry in DNS points to your Linode's IP) on port 9090. As an example, if your Linode's IP address were "126.96.36.199", you would visit http://188.8.131.52:9090 in your web browser. You will be presented with a language selection screen similar to this:
Next, you'll be asked to configure your domain and ports for administration. Use the fully qualified domain name you have assigned to your Linode in DNS (more infomation: configuring DNS with the Linode Manager).
You may choose to use Openfire's embedded database for account management, or you may connect to an external database. Most users will want to choose the built-in option.
User profiles may be stored in the server database, or they may be pulled from LDAP or Clearspace. Most users will want to choose the default option.
Enter the email address of the default administrative user and select a strong password.
After the initial web-based configuration is complete, restart the Openfire server before attempting to log in with the default "admin" user account.
If you're experiencing difficulty using the credentials you just created to log in, please use "admin/admin" as the username/password. You'll need to update your credentials immediately afterward for security purposes. Congratulations! You've successfully installed the Openfire RTC server on Debian Linux!
