supervisor 从安装到使用

**一、安装**

*  源码安装

先下载最新的supervisor安装包：[https://pypi.python.org/pypi/supervisor][https_pypi.python.org_pypi_supervisor] ， 如：

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 #本地python版本为python2.7
    # python2.7 setup.py install #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.配置

打开配置文件

vim /etc/supervisord.conf

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

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

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

*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

4.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 进程名 ：启动XXX进程
    supervisorctl stop 进程名 ：停止XXX进程
    supervisorctl stop all：停止全部进程，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

5.若不使用控制台来管理进程，用浏览器来管理，该如何配置？

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=xxx        ;自定义
    password=xxx        ;自定义

**三、设置开机启动**

vim /etc/init.d/supervisord

添加以下脚本

#! /bin/sh
    ### BEGIN INIT INFO
    # Provides: supervisord
    # Required-Start: $remote_fs
    # Required-Stop: $remote_fs
    # Default-Start: 2 3 4 5

    }

    do_stop()
    {

        # 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.

        [ "$?" = 2 ] && return 2

# 设置该脚本为可以执行
    sudo chmod +x /etc/init.d/supervisord
    # 设置为开机自动运行
    sudo update-rc.d supervisord defaults
    # 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
