2、开机启动

vim /etc/init.d/supervisord
加入以下内容

#!/bin/bash
#
# supervisord   This scripts turns supervisord on
#
# Author:       Mike McGrath <mmcgrath@redhat.com> (based off yumupdatesd)
#
# chkconfig:    - 95 04
#
# description:  supervisor is a process control utility.  It has a web based
#               xmlrpc interface as well as a few other nifty features.
# processname:  supervisord
# config: /etc/supervisor/supervisord.conf
# pidfile: /var/run/supervisord.pid
#

# source function library
. /etc/rc.d/init.d/functions

RETVAL=0

start() {
    echo -n $"Starting supervisord: "
    daemon "/usr/bin/supervisord -c /etc/supervisord.conf"
    RETVAL=$?
    echo
    [ $RETVAL -eq 0 ] && touch /var/lock/subsys/supervisord
}

stop() {
    echo -n $"Stopping supervisord: "
    killproc supervisord
    echo
    [ $RETVAL -eq 0 ] && rm -f /var/lock/subsys/supervisord
}

restart() {
    stop
    start
}

case "$1" in
  start)
    start
    ;;
  stop) 
    stop
    ;;
  restart|force-reload|reload)
    restart
    ;;
  condrestart)
    [ -f /var/lock/subsys/supervisord ] && restart
    ;;
  status)
    status supervisord
    RETVAL=$?
    ;;
  *)
    echo $"Usage: $0 {start|stop|status|restart|reload|force-reload|condrestart}"
    exit 1
esac

exit $RETVAL

chmod +x /etc/init.d/supervisord
chkconfig supervisord on

3、使用技巧

tail /etc/supervisord.conf -n 20

;[group:thegroupname]
;programs=progname1,progname2  ; each refers to 'x' in [program:x] definitions
;priority=999                  ; the relative start priority (default 999)

; The [include] section can just contain the "files" setting.  This
; setting can list multiple files (separated by whitespace or
; newlines).  It can also contain wildcards.  The filenames are
; interpreted as relative to this file.  Included files *cannot*
; include files themselves.

;[include]
;files = relative/directory/*.ini
[include]
files = /etc/supervisord.d/*.conf
