Supervisor服务开机自启动

要解决的问题

在机器上部署自己编写的服务时候,我们可以使用Supervisor作为进程检活工具,用来自动重启服务。
但是当机器重启后,Supervisor却不能自动重启,那么谁来解决这个问题呢?

答案就是linux的service。

总体思路

编写一个脚本,然后把它放在/etc/init.d这个目录下,再用service + 脚本名字 运行即可。如果是要开机自动启动那就得用chkconfig命令了。

话不多说,上手做吧!

安装方法

增加service配置

[root@hdx9whvy init.d]# vim /etc/init.d/supervisor

内容为

#!/bin/bash
#
# supervisord   This scripts turns supervisord on
#
# Author:       Mike McGrath <[email protected]> (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

设置脚本为可执行

[root@hdx9whvy init.d]# chmod +x /etc/init.d/supervisor

设置服务开机启动

  • service这个命令往往是即时生效,不用开关机,但是重启后服务会回到默认状态。
  • chkconfig是用于把服务加到开机自动启动列表里,只要启动它,就能自动启动,重启后永久生效
[root@hdx9whvy init.d]# chkconfig supervisor on

启停命令

[root@hdx9whvy init.d]# service supervisor start
Starting supervisord:                                      [  OK  ]

[root@hdx9whvy init.d]# service supervisor stop
Stopping supervisord:                                      [  OK  ]

[root@hdx9whvy ~]# service supervisor restart
Stopping supervisord:                                      [  OK  ]
Starting supervisord:                                      [  OK  ]
