How to install different versions of Wowza Media Server on one computer

This article describes how to install different versions of Wowza Media Server™ on one computer for testing and comparison purposes. Only one version should be running at any time to avoid network port conflicts. All installed Wowza Media Server versions must be properly licensed.

Linux

• /usr/local/WowzaMediaServer-3.1.2
• /usr/local/WowzaMediaServer-3.6.1

Windows

• C:\Program Files (x86)\Wowza Media Systems\Wowza Media Server 3.1.2
• C:\Program Files (x86)\Wowza Media Systems\Wowza Media Server 3.6.1

Linux configuration

The Linux installer creates a symbolic link in /usr/local named WowzaMediaServer that points to the most recent installation. The same symbolic link is used by all versions, so if version 3.1.2 was previously installed and version 3.6.1 is installed later, the link will point to the version 3.6.1 installation. You must update the symbolic link to point to the version that you want to run before starting the server. For example, if version 3.6.1 is required, update the link as follows:

sudo ln -s /usr/local/WowzaMediaServer-3.6.1 /usr/local/WowzaMediaServer
