• 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.

    Note: For more information about how to run multiple instances of the same version of Wowza Media Server on the same computer, see How to run multiple instances of Wowza Media Server on one computer.
    Each different version of Wowza Media Server is installed to a folder with a unique folder name. For example:

    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

    Windows configuration

    To switch between installed versions on Windows platforms, you must update the following environment variables to point to the required installation version:

    • WMSAPP_HOME

    • WMSCONFIG_HOME

    For example, to switch from Wowza Media Server 3.1.2 to Wowza Media Server 3.6.1, do the following:

    1. Open System Properties (Start > Control Panel > System and Security > System > Advanced system settings).

    2. On the Advanced tab, click Environment Variables.

    3. In System Variables, edit the WMSAPP_HOME variable value and then click OK:

      Change:
      C:\Program Files (x86)\Wowza Media Systems\Wowza Media Server 3.1.2
      To:
      C:\Program Files (x86)\Wowza Media Systems\Wowza Media Server 3.6.1
    4. In System Variables, edit the WMSCONFIG_HOME variable value and then click OK:

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

    5. On the Advanced tab, click Apply.

    The server can then be started normally.
