This?
I have no idea how to read it, it's clearly meant to be parsed and filled in before use. I don't know how to interpret %%JAVA_CMD%% for instance.

yeah, cause when I build my port it gets parsed. %%JAVA_CMD%%=/usr/local/openjdkX/bin/java
I assume you would just have

Code:

command="/usr/local/bin/mono"
command_args="whatever.exe >$LOGFILE 2>&1 &"

The '>LOGFILE 2>&1 &' would redirect the errors and output to a logfile instead of the terminal

if you define a pidfile (which I see you already did), all of your functions (pre/post)start, (pre/post) stop, would be done by the subroutines that the init system provides.

OK, I already did the logfile actually. I'll try it out. Thanks.

By the way, any idea how I get the logfile to rotate daily?

 

[tofagerl]

Well, that worked really well, except now the pidfile isn't there, yet service status still works.

hmm, actually now that i remember.. pidfile is only defined in your rc script. but it expects you program to actually create it. If you don't need a pidfile then don't define one. the init can figure our what process it is by looking at the user + command + command_args

EDIT
yup,looking at my subsonic script i don't define one. I do in most of my other sciprts cause the programs create their own pid, but with subsonic I just let the init figure it out.

 

[tofagerl]

Right, I need it for monit, but I can edit the monit config so it finds the pid from ps and grep.

ahh, i see. maybe monit could ask the init file for the current status.

 

[tofagerl]

Nah, it needs an actual pidfile as it turns out, so I would need to create a wrapper script, which would fuck up the rc script... Sigh...

i think you could just define the pidfile in a prestart command like you were doing before.

 

[tofagerl]

Maybe, but can I create just the poststart, which I assume you meant, and not the start and stop commands? Hell, why ask, I'll just try it. Faster that way ;)

yup, poststart is where it should go. was up way too late last night =P
I sometimes define prestart commands if a program can't deal with a stale pidfile on it's own.

 

[tofagerl]

That works, except the poststop command doesn't delete the pidfile like I told it to.
Nevermind, I forgot to designate the stop_postcmd var.

Thanks a lot for your help, I'm about ready to publish this on the nzbdrone forum. here's the final file for your amusement:

mind posting what you currently have?

Can you please post your final working script tofagerl. Thanks.

Edit: nvm found it on the NZBDRONE forums, thanks for the script!

Looks good. Mind checking if my changes works

Changes I made

• I simplified nzbdrone_poststart() to utlize a built in variable
• no need deleting a stale pidfile then overwriting it. just overwriting it would do the same thing.
• utilized nzbdrone_dir

Future changes

• can you specify "nzbdrone_data_dir" as a commandline flag to nzbdrone? if so maybe we should specify it to something like /usr/local/etc/nzbdrone (but this directory would need to be owned by nzbdrone_user). otherwise the variable can be deleted, it's not being used.
• if the above is implemented we might want to specify a user other than nobody to own the config files. it would need to either be a built in account, or people would need to add it. (though this is something a port maintainer would need to think about, not something that needs to be taken care of in this script)

I cannot seem to get the service started with the script using any user except root. When I attempt to load the service it does not start. If I change the user to root in the rc script it will start. I have made sure that the user/group has been created and that the user has access to the NzbDrone folder/files. I am probably missing something obvious here, just not sure what.

the user probably needs a home directory to create it's config directory. might be a possible issue.

Is that not created by default?
