Start Stop Script for FreeBSD

[ALHSLeo 10]

Standart start script for arma2 linux server correctly don't work under FreeBSD, server starts, but don't stops.

This is changed startup script - working under FreeBSD :

This script kill by process name all processes, and normally stop arma2 server. But : if you start different arma 2 servers from 1 user shell - then better create different users for different arma 2 servers, or rename binaries, and change line : SERVER_BIN, becouse this scripts kills other arma 2 servers running under this user.

Script version 0.2 - added email to admin if server restarts, added normal killing of processes with watchdog - if central server process died ( reason - on the FreeBSD - if the centrall process died - server try to create another processes, but don't kill other running processes - and server can't start after crash).

P.S. If you wanna bind processes for cpecified cores of cpu - change the folloving line :

from :
${SERVER} >>${LOGFILE} 2>&1 -server -cfg=${CFG} -config=${CONFIG} -port=${PORT} -pid=${PIDFILE} -mod=${MODS}
to :
/usr/bin/cpuset -l 0,1,2 -s armaserv ${SERVER} >>${LOGFILE} 2>&1 -server -cfg=${CFG} -config=${CONFIG} -port=${PORT} -pid=${PIDFILE} -mod=${MODS} -cpuCount=3

Awesome ! Is there anything like this available for Windows dedicated Servers ? Already searching for a while but I can't find anything....:(

[calo_mir 10]

Nice to see someone else doing it.

Ever tried djb's daemontools? Handles process supervision very cleanly. I've not got around to setting up the server on FreeBSD yet but I expect that's the way I'd go about it.

[ALHSLeo 10]

/usr/ports/sysutils/daemontools/ - this daemon in ports available, but i don;t see, how always, reason to installing another daemon for checking needed daemon, who checks daemontools then ? :)

P.S. Better to insert some changes in standart Linux startup script for FreeBSD usage ( on the freebsd for one arma 2 server i have 6 processes on quad core cpu, standart Linux script kill only first process ), and check server with it, without installing another program.
