从Hudson运行时，Tomcat脚本不起作用

Question

I'm trying to run a script which stops and starts Tomcat on linux.

When I run it from the command line it works fine. But it does not seem to work when I run the same script from the "Execute Shell" build step in a Jenkins/Hudson job. Jenkins doesn't report any errors but if I try going to the tomcat page then I get a page not found error.

So Jenkins seems able to stop the server, but not bringing it back up.

I'd be grateful for any help.

Answer 1

Try unsetting the BUILD_ID in your 'shell execute' block. You might even not need to use nohup in this case

BUILD_ID=
./your_hudson_script_that_starts_tomcat.sh

Answer 2

Without seeing your script it is difficult to give an exact answer. However you could try adding the following to the start of your script (assuming it is a bash script):

# Trace executed commands.
set -x

# Save stdout / stderr in files
exec >/tmp/my_script.stdout
exec 2>/tmp/my_script.stderr

You could also try adding

set -e

to make the shell exit immediately if a command returns an error status.

If it looks as though Hudson is killing off Tomcat then you might want to run it within nohup (if you're not already doing that):

nohup bin/startup.sh >/dev/null 2>&1 &
