Hi,
I'm trying to deal with a rc script I'm writing to launch a deamon.
I wrote it based on the hanbook rc script sample. It works pretty
well but I have some (strange to me) warning message.
Your script looks pretty good, but it needs a little work. :) I
assume that you wrote this based on the handbook examples for the
base. You should probably take a look at the one for ports too:
http://www.freebsd.org/doc/en_US.ISO8859-1/books/porters-handbook/rc-scripts.html
Fisrt a short explanation about what i'm doing : The application is
a python script deamon started by a shell script located in
/usr/local/sbin/ntlmaps. The shell script launch the application
and write the pid file if require
So, the rc script (ntlmapsd)
The name of the script, the $name value, and the REQUIRE: value should
all match. So you should either name them all ntlmapsd, or ntlmaps.
There is no conflict between the script name and the binary in
/usr/local/sbin/, FYI.
calls the shell script with the right
arguments to start the application, then performs a 'kill -KILL' to
stop it based on the pid file information.
The thing is stopping the application I receive a message saying:
./ntlmapsd: WARNING: $command_interpreter -b != /bin/sh
This is a tricky one because what you did looks totally reasonable
since the script you're calling does use /bin/sh. However the
command_interpreter value for rc.d needs to be what the _process_ is
running, which in this case is /usr/local/bin/python.
I've attached an example script that might work for you. Personally I
would not make the pidfile stuff optional, in which case you could
simplify things to the one in -v2. Whatever you decide, please test it
thoroughly first.
In addition to the web pages another good resource is to read through
the comments in /etc/rc.subr.
hth,
Doug
