What do you get when you type in the following command:

java -version

Uninstall again and this time try the rpm installer.

You either have Wowza running twice or FMS and Wowza running at the same time. Try rebooting. Then see what you get when you execute the command:

ps -ef | grep java

If you see Wowza is already running then it is running as a service and you don’t need to start it standalone.

</div>

Which installer did you use (rpm, deb, tar)? What Linux distro are you running?

Also, try editing bin/startup.sh and adding echo to the last line in the file:

```auto
from:
$_EXECJAVA $JAVA_OPTS $JMXOPTIONS -Dcom.wowza.wms.AppHome="$WMSAPP_HOME" -Dcom.wowza.wms.ConfigURL="$WMSCONFIG_URL" -Dcom.wowza.wms.ConfigHome="$WMSCONFIG_HOME" -cp $WMSAPP_HOME/bin/wms-bootstrap.jar com.wowza.wms.bootstrap.Bootstrap start
to:
echo $_EXECJAVA $JAVA_OPTS $JMXOPTIONS -Dcom.wowza.wms.AppHome="$WMSAPP_HOME" -Dcom.wowza.wms.ConfigURL="$WMSCONFIG_URL" -Dcom.wowza.wms.ConfigHome="$WMSCONFIG_HOME" -cp $WMSAPP_HOME/bin/wms-bootstrap.jar com.wowza.wms.bootstrap.Bootstrap start

```

Then run ./startup.sh and send me the result. I want to see the command line that is being executed.

Wait, I see the problem. The installation path is wrong. It is:

/usr/local/WowzaMediaServerPro/WowzaMediaServerPro-1.7.2/bin

It should just be:

/usr/local/WowzaMediaServerPro/bin

Where:

/usr/local/WowzaMediaServerPro

Is a symbolic link to:

/usr/local/WowzaMediaServerPro-1.7.2

So something got messed up in the install. Do you have any idea what might have gone wrong with the install?
