bash - Monit fails to start process -
i've written scrip works fine start , stop server.
#!/bin/bash pid_file='/var/run/rserve.pid' start() { touch $pid_file eval "/usr/bin/r cmd rserve" pid=$(ps aux | grep rserve | grep -v grep | awk '{print $2}') echo "starting rserve pid $pid" echo $pid > $pid_file } stop () { pkill rserve rm $pid_file echo "stopping rserve" } case $1 in start) start ;; stop) stop ;; *) echo "usage: rserve {start|stop}" ;; esac exit 0 if start running
rserve start and start monit correctly capture pid , server:
the monit daemon 5.3.2 uptime: 0m remote host 'localhost' status online services monitoring status monitored port response time 0.000s localhost:6311 [default via tcp] data collected mon, 13 may 2013 20:03:50 system 'system_gauss' status running monitoring status monitored load average [0.37] [0.29] [0.25] cpu 0.0%us 0.2%sy 0.0%wa memory usage 524044 kb [25.6%] swap usage 4848 kb [0.1%] data collected mon, 13 may 2013 20:03:50 if stop it, kill process , unmonitor it. if start again, won't start server again:

i had problem start or stop process via shell too. 1 solution might add "/bin/bash" in config this:
start program = "/bin/bash /urs/bin/rserv start" stop program = "/bin/bash /urs/bin/rserv stop" it worked me.
