Hi,

Does anyone have a script running as daemon on Linux/Unix (variants) as part
of your PHP application? If so, what are you using to schedule the script
to run? cron?

Thanks,
Tommy

cron is one way to do it for scripts you schedule. for real daemon
processes though ive recently deployed a php script on gentoo by leveraging
the init scripts. essentially my program runs a while(true) and uses
pcntl_fork() to create worker children. the parent process listens for
signals which are sent by an init script. theres also a really nice
start-stop-daemon function in the init script library which backgrounds the
process for me and creates a pid lockfile. really slick.

now i have an interface to my script like

/etc/init.d/php-service start

etc. plus it ties right into the runlevel scripts, i just run

rc-update add php-service default

and the script will start when the box hits runlevel 3!

Yeah that's what I do too. Of course systemd will change everything
"initscript" related, but I don't expect it to hit production servers
for a while.

Could easily be years - the init-sequence is only interesting at
boot-time, and server runs for years (wel, mine certainly do).
