stop Tomcat instances

Hello.

im unable to stop Tomcat instances with Ansible.
in the shell, i just need to type /etc/init.d/tomcat7_stop instance01

i found this .yml file and it’s written

  • name: stop tomcat
    service: name=tomcat state=stopped pattern={{instance}} args={{instance}}

but i don’t know what i supposed to fill in the “pattern” and in “args”

thanks

​"pattern" is a literal pattern on which you would grep on a full ps output.
That could be 'java', but you probably want to note something more
specific, depending on the full command line​ which starts your tomcat.

Given that tomcat sometimes doesn't stop, as in hangs or as in takes a long
time to stop, I combine this with a custom module i wrote, that has
different options to check on a process, whether it stopped, and to kill it
nicely, or later on not so nicely:

HTH,

not sure i quite understand…

when i did vi /etc/init.d/tomcat7_stop instance01 … this is how it stops the service:

instance01)
su tomcat7_01 -c “/var/tomcat7_instances/instance01/bin/shutdown.sh”
pkill -9 -u tomcat7_01
;;

and when i type ps -aux | grep java … the output is:

I would also point out that "/etc/init.d/tomcat7_stop instance01"
does not look like a standard init script, this will not work with the
service module.

I've used multi instance tomcat scripts before but they were either:
/etc/init.d/tomcat7_instance01 stop
works using tomcat7_instance01 as service name

or
/etc/init.d/tomcat7 stop instance01
which is supported by the arguments parameter arguments=instance01

i was able to run it like this:

  • name: stop tomcat
    sudo: yes
    command: /etc/init.d/tomcat7_stop instance01

but failed to run the second command: pkill -9 -u tomcat7_01
received this output:

FATAL: all hosts have already failed – aborting

how could i write it the write way?
or is it better to fill the previous command? tomcat state=stopped pattern={{instance}} args={{instance}}

thanks!

Hi Sharon,

As this is a user-level question, can you please continue this over on ansible-project list?

Thanks!
