#easy_install
supervisor
#supervisord
--version
#vi
/etc/supervisord.conf

# echo_supervisord_conf > /etc/supervisord.conf
Running the service
#Touch /etc/rc.d/init.d/supervisord
Add below
scrip to above file
#!/bin/bash
.

if [ -f $PIDFILE ]; then
PID=`cat $PIDFILE`
echo supervisord already
running: $PID
exit 2;
else
daemon $DAEMON --pidfile=$PIDFILE -c
/etc/supervisord.conf
RETVAL=$?
echo
[ $RETVAL -eq 0 ] &&
touch /var/lock/subsys/supervisord
return $RETVAL
fi
}
stop()
{
echo -n "Shutting down

echo
killproc -p $PIDFILE supervisord
echo
rm -f /var/lock/subsys/supervisord

Creating process pools
Create pool
Group name: pool1
Programs: web4 / web5
vi /etc/supervisor/conf.d/pool1.conf
[group:pool1]
programs=web4,web5
[program:web4]
command=java
-jar stability-1.0-SNAPSHOT-jar-with-dependencies.jar dev
directory=/opt/85
autostart=true
autorestart=true
startretries=3
stderr_logfile=/var/log/web4/web4.err.log
stdout_logfile=/var/log/web4/web4.out.log
[program:web5]
command=java
-jar stability-1.0-SNAPSHOT-jar-with-dependencies.jar dev
directory=/opt/86
autostart=true
autorestart=true
startretries=3
stderr_logfile=/var/log/web5/web5.err.log
stdout_logfile=/var/log/web5/web5.out.log
After that restart the supervisord
# /etc/init.d/supervisord restart
