Answer 1

Try

mfp -d start

or

mfp -dd start

I got a different startup problem and I have no clues what happened because the prompt returned normally. Until I run mfp -d start to find out tools.jar is not in the classpath. Therefore, I updated %JAVA_HOME% and %PATH% variables and this resolved my problem.

You may also want to check logs with

mfp logs

Update #1 Per your comment, it seems that the JVM somehow failed to start with exit code = 1. I would check that area first. For example, a simple search hits similar issues not specific to MFP and seems to point to a defect in JDK on Mac OS X. https://stackoverflow.com/a/20807657/2821355

Hope this helps

Answer 2

Update:

Download the latest CLI iFix relese from IBM Fix Central (June 6th 2015 and above) as it contains fixes (That at least for me) allow for the server to properlly start.

Uninstall the current CLI installation Download the latest CLI from IBM Fix Central website Install new version and try again

Are you also using MobileFirst Studio? You might have a server process still running.

Try this, from Terminal:

1. lsof -i :10080
2. If you get a list of process, then
3. kill -9 number-of-process
