Run it with option -P to store the PID in some temp file. For example:

/usr/local/bin/spawn-fcgi -a 127.0.0.1 -p 9000 -P /var/run/fcgi.pid

Then you can kill it by this pid:

kill -9 `cat /var/run/fcgi.pid`

And make sure that PID file is writable by spawned process (if you're using -u/-g options) or it will be empty – sendmoreinfo Aug 12 '12 at 13:22

Try this:

How was the process for spawn-fcgi started, was it by a command line (manually) or using a rc-script. In either case you can kill the process by first finding the PID

Use the command ps aux | grep spawn-fcgi to locate the process and the command kill -9 PID

I recommend slashdot's recommendation of using the rc-script to start and end your spawn-fcgi process.

Update: This answer randomly failed on me (I'm not sure why) but I'm leaving this here because it might help someone.

killall -9 -w php-cgi

The "-w" waits. Because if you try to (re)start spawn-fcgi too soon (without a delay) spawn-fcgi always gave me error, something like "...already in use." (I don't remember the exact error, sorry.) However, "-w" doesn't work 100% of the time if you plan to put this in cron. After months of random php failures I decided to switch to php-fpm, which has its own unique problems--proceed with caution.

I actually prefer to do this kind of process management by using supervisor: http://supervisord.org/

Supervisor will "hang on to your processes": it will restart as necessary, manage the stdout/stderr logging and give you an explicit command for managing the processes without having to mess with PID files etc.

restart spawn-fcgi
