一、安装

下载最新的supervisor安装包：https://pypi.python.org/pypi/supervisor

cd /usr/local/src

wget https://pypi.python.org/packages/7b/17/88adf8cb25f80e2bc0d18e094fcd7ab300632ea00b601cbbbb84c2419eae/supervisor-3.3.2.tar.gz

tar -zxvf supervisor-3.3.2.tar.gz

cd supervisor-3.3.2

python setup.py install

Tips：错误1：error: Could not find suitable distribution for Requirement.parse(‘meld3>=0.6.5‘)，安装meld扩展

 wget https://pypi.python.org/packages/45/a0/317c6422b26c12fe0161e936fc35f36552069ba8e6f7ecbd99bbffe32a5f/meld3-1.0.2.tar.gz#md5=3ccc78cd79cffd63a751ad7684c02c91
 tar zxvf meld3-1.0.2.tar.gz
cd meld3-1.0.2
 python setup.py install

Tips：本地python版本为python3以上

二、配置

1.生成配置文件

echo_supervisord_conf > /etc/supervisord.conf

2.启动

supervisord -c /etc/supervisord.conf

##查看 supervisord 是否在运行：

ps aux | grep supervisord

3.基础配置

（1）打开配置文件

vim /etc/supervisord.conf

（2）在配置文件底部，配置include

[include]
files=/etc/supervisor/*.conf  #若你本地无/etc/supervisor目录，请自建

（3）用supervisor管理进程，配置如下：

cd /etc/supervisor
vim ossfs.conf # 这里的文件名称自定义

（4）加入以下内容：

; 设置进程的名称，使用 supervisorctl 来管理进程时需要使用该进程名
[program:your_program_name] 
command=python server.py --port=9000
;numprocs=1                 ; 默认为1
;process_name=%(program_name)s   ; 默认为 %(program_name)s，即 [program:x] 中的 x
directory=/home/python/tornado_server ; 执行 command 之前，先切换到工作目录
user=oxygen                 ; 使用 oxygen 用户来启动该进程
; 程序崩溃时自动重启，重启次数是有限制的，默认为3次
autorestart=true            
redirect_stderr=true        ; 重定向输出的日志
stdout_logfile = /var/log/supervisord/tornado_server.log
loglevel=info

（5）这里是启动要配置的参数，请根据自己的项目自定义添加
更改了supervisor配置文件，需要重启,运行以下指令：

supervisorctl reload

（6）服务启动

supervisord -c /etc/supervisord.conf 

（7）用浏览器来管理进程配置
打开配置文件

vim /etc/supervisord.conf

配置 inet_http_server

[inet_http_server]       
port=127.0.0.1:9001; 服务器ip
username=username ;自定义
password=password ;自定义

三、supervisorctl的用法

supervisord : 启动supervisor

supervisorctl reload :修改完配置文件后重新启动supervisor

supervisorctl status :查看supervisor监管的进程状态

supervisorctl start all | 进程名 ：启动全部或某进程

supervisorctl stop all | 进程名 ：停止全部或某进程

supervisorctl stop all：停止进程，注：start、restart、stop都不会载入最新的配置文件。

supervisorctl update：根据最新的配置文件，启动新配置或有改动的进程，配置没有改动的进程不会受影响而重启

四、设置开机启动

（1）添加开机脚本

vim /etc/init.d/supervisord

脚本如下：

#! /bin/sh
### BEGIN INIT INFO
# Provides:          supervisord
# Required-Start:    $remote_fs
# Required-Stop:     $remote_fs
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: Example initscript
# Description:       This file should be used to construct scripts to be
#                    placed in /etc/init.d.
### END INIT INFO

# Do NOT "set -e"

#
do_start()
{
    # Return

    start-stop-daemon --start --quiet --pidfile $PIDFILE --exec $DAEMON --test > /dev/null \
        || return 1

}

#
# Function that stops the daemon/service
#
do_stop()
{
    # Return
    #   0 if daemon has been stopped
    #   1 if daemon was already stopped
    #   2 if daemon could not be stopped
    #   other if a failure occurred
    start-stop-daemon --stop --quiet --retry=TERM/30/KILL/5 --pidfile $PIDFILE --name $NAME
    RETVAL="$?"
    [ "$RETVAL" = 2 ] && return 2
    # Wait for children to finish too if this is a daemon that forks
    # and if the daemon is only ever run from this initscript.
    # If the above conditions are not satisfied then add some other code
    # that waits for the process to drop all resources that could be
    # needed by services started subsequently.  A last resort is to
    # sleep for some time.
    start-stop-daemon --stop --quiet --oknodo --retry=0/30/KILL/5 --exec $DAEMON
    [ "$?" = 2 ] && return 2
    # Many daemons don't delete their pidfiles when they exit.
    rm -f $PIDFILE
    return "$RETVAL"
}

#
# Function that sends a SIGHUP to the daemon/service
#
do_reload() {
    #
    # If the daemon can reload its configuration without
    # restarting (for example, when it is sent a SIGHUP),
    # then implement that here.
    #
    start-stop-daemon --stop --signal 1 --quiet --pidfile $PIDFILE --name $NAME
    return 0
}

case "$1" in
  start)
    [ "$VERBOSE" != no ] && log_daemon_msg "Starting $DESC" "$NAME"
    do_start
    case "$?" in
        0|1) [ "$VERBOSE" != no ] && log_end_msg 0 ;;
        2) [ "$VERBOSE" != no ] && log_end_msg 1 ;;

    do_stop
    case "$?" in
      0|1)
        do_start
        case "$?" in
            0) log_end_msg 0 ;;
            1) log_end_msg 1 ;; # Old process is still running
            *) log_end_msg 1 ;; # Failed to start
        esac

    #echo "Usage: $SCRIPTNAME {start|stop|restart|reload|force-reload}" >&2
    echo "Usage: $SCRIPTNAME {start|stop|restart|force-reload}" >&2
    exit 3
    ;;
esac
:

（2）设置该脚本为可以执行

sudo chmod +x /etc/init.d/supervisord

（3）设置为开机自动运行

sudo update-rc.d supervisord defaults

（4）试一下，是否工作正常

service supervisord stop

service supervisord start

若报错：insserv: warning: script 'service' missing LSB tags and overrides，请执行:

sudo apt-get remove insserv

五、错误排查

1、unix:///var/run/supervisor/supervisor.sock no such file

问题描述：安装好supervisor没有开启服务直接使用supervisorctl报的错
解决办法：启动服务

supervisord -c /etc/supervisord.conf 

2、启动了多个supervisord服务，导致无法正常关闭服务

问题描述：多次运行supervisord -c /etc/supervisord.conf 或supervisord，导致有些进程被多个superviord管理，无法正常关闭进程。
解决办法：kill相关的进程。

ps -fe | grep supervisord    #查看所有启动过的supervisord服务

kill -9 PID                           #kill相关进程
