Linux supervisor 安裝與使用

1，安裝：pip install supervisor

2，生成配置文件：echo_supervisord_conf > /etc/supervisord.conf

3，編輯配置文件：vim /etc/supervisord.conf

修改最后兩行，去掉前面的分號。

[include]

files = /etc/supervisord/*.conf

這是存放進被管理的進程的配置文件

4，開啟web控制台：找到如下幾行，去掉注釋

[inet_http_server] 　　; inet (TCP) server disabled by default

port=0.0.0.0:9001 　　; ip_address:port specifier, *:port for all iface

username=admin 　　; default is no username (open server)

password=123456 　　; default is no password (open server)

 

之后可以通過web界面登錄管理，查看日志等

 

5，添加管理進程的配置文件

mkdir /etc/supervisord/

vim /etc/supervisord/test1.conf

[program:test1]
user=root
directory=/usr/local/test/
command=/usr/local/bin/python /usr/local/test/test.py
autostart=true
autorestart=true
loglevel=debug
log_stderr=true
stdout_logfile=/var/log/test1.log
redirect_stderr=true

如需管理多個進程，那就配置多個文件

6，啟動superv

supervisord -c /etc/supervisord.conf

 

7, 查看管理進程的狀態

supervisorctl status　　（被管理的進程會隨着supervisor主進程的啟動而啟動）

 

8，關閉，啟動，重啟

supervisorctl stop|start|restart test1

 

9，關閉supervisor

ps -ef | grep super，然后kill -9 殺進程

 

10，注意，直接殺掉supervisor的主進程，被管理的進程仍然運行狀態，所以記得先stop被管理的進程。

如果修改了各個配置文件，都需要重啟supervisor。

 

補充：添加supervisord服務，設置開機啟動

上面安裝的沒有生成supervisord這個服務，自己參考改一個

文件如下：vim /etc/init.d/supervisord

#!/bin/sh
##
## /etc/rc.d/init.d/supervisord
##
#supervisor is a client/server system that
# allows its users to monitor and control a
# number of processes on UNIX-like operating
# systems.
#
# chkconfig: - 64 36
# description: Supervisor Server
# processname: supervisord

# Source init functions
. /etc/rc.d/init.d/functions

prog="supervisord"
prefix="/usr/local/"
exec_prefix="${prefix}"
PIDFILE="/var/run/supervisord.pid"
CONFIG="/etc/supervisord.conf"
prog_bin="${exec_prefix}bin/supervisord -c $CONFIG "

function log_success_msg() {
        echo "$@" "[ OK ]"
}

function log_failure_msg() {
        echo "$@" "[ OK ]"
}

start()
{
       #echo -n $"Starting $prog: "
       #daemon $prog_bin --pidfile $PIDFILE
       #[ -f $PIDFILE ] && success $"$prog startup" || failure $"$prog failed"
       #echo
        if [ ! -r $CONFIG ]; then
                log_failure_msg "config file doesn't exist (or you don't have permission to view)"
                exit 4
        fi

        if [ -e $PIDFILE ]; then
                PID="$(pgrep -f $PIDFILE)"
                if test -n "$PID" && kill -0 "$PID" &>/dev/null; then
                        # If the status is SUCCESS then don't need to start again.
                        log_failure_msg "$NAME process is running"
                        exit 0
                fi
        fi

        log_success_msg "Starting the process" "$prog"
        daemon $prog_bin --pidfile $PIDFILE
        log_success_msg "$prog process was started"

}
stop()
{
       echo -n $"Shutting down $prog: "
       [ -f $PIDFILE ] && killproc $prog || success $"$prog shutdown"
       echo
}

case "$1" in

 start)
   start
 ;;

 stop)
   stop
 ;;

 status)
       status $prog
 ;;

 restart)
   stop
   start
 ;;

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

esac

 

文件中的prefix和config變量記得檢查下

給文件執行權限

chmod -R 755 /etc/init.d/supervisord

添加服務

chkconfig --add supervisord

設置開機啟動

chkconfig  supervisord on

 

測試：

測試前先把之前啟動的supervisord進程和子進程殺掉，kill -9

然后

service supervisord start

service supervisord stop

管理的子進程也會一並起來和殺死
