echo_supervisord_conf > supervisord.conf
sudo cp supervisord.conf /etc/supervisord.conf
sudo mkdir /etc/supervisord.d/
sudo vi /etc/supervisord.conf
# 把下面的这两行的注释去掉，如果没有加上即可。
[include]
files = /etc/supervisord.d/*.conf

创建一个配置文件到/etc/supervisord.d/ 比如 /etc/supervisord.d/shadowsocks.conf

[program: ] (  is name of program)
command=/bin/  //Execute command
process_name=%(program_name)s //if your numprocs is more than 1 it should be %(program_name)s_%(process_num)02d 
numprocs=1 //Number of your concurrent process Perfect for gearman
directory=/tmp //cd this directory before running
priority=999 //priority or program maximum is 999
autostart=true
autorestart=true
startretries=3 //number of retrying times if process is die
stopwaitsecs=10 //waiting xx second before before stop
user=chrism //exec by user should be “root”
//Log control 
stdout_logfile=/a/path
stdout_logfile_maxbytes=1MB

start()

       echo -n $"Starting $prog: "
       daemon $prog_bin --pidfile $PIDFILE -c /etc/supervisord.conf
       [ -f $PIDFILE ] && success $"$prog startup" || failure $"$prog startup"
       echo

       echo
}

case "$1" in

   start

 stop)
   stop

 status)
       status $prog
 ;;

 restart)
   stop
   start

 *)
   echo "Usage: $0 {start|stop|restart|status}"

sudo chkconfig --add supervisord
sudo chkconfig supervisord on
sudo service supervisord start

网页界面查看

修改/etc/

把

2
;[inet_http_server]         ; inet (TCP) server disabled by default
;port=*:9001        ; (ip_address:port specifier, *:port for all iface)

改为(即去掉注释）

2
[inet_http_server]         ; inet (TCP) server disabled by default
port=*:9001        ; (ip_address:port specifier, *:port for all iface)

在浏览器输入http://Host:9001 就可以查看了。
