### 超级管理工具supervisor ###

#### 安装supervisor的方式有很多, 如: ####

`pip install supervisor`

`yum, apt etc.`

### 创建一个配置文件 ###

一旦你安装好supervisor以后, 运行 `echo_supervisor_conf`会在你的terminal里面打印一个"sample"配置文件供你查看  
当你看到echo给你的文件以后, 可以使用命令 `echo_supervisor_conf > /etc/supervisord.conf`将配置文件定向输入到你指定的目录文件中, 当然这个操作需要root权限.

ww@ww-Lenovo-ideapad-Y700-14ISK:/etc$ echo_supervisord_conf
    ; Sample supervisor config file.
    ;
    ; For more information on the config file, please see:
    ; http://supervisord.org/configuration.html
    ;
    ; Notes:
    ;  - Shell expansion ("~" or "$HOME") is not supported.  Environment
    ;    variables can be expanded using this syntax: "%(ENV_HOME)s".
    ;  - Quotes around values are not supported, except in the case of
    ;    the environment= options as shown below.
    ;  - Comments must have a leading space: "a=b ;comment" not "a=b;comment".
    ;  - Command will be truncated if it looks like a config file comment, e.g.
    ;    "command=bash -c 'foo ; bar'" will truncate to "command=bash -c 'foo ".

如果你没有root权限, 或者你不想把`supervisord.conf`文件放到`/etc/supervisord.conf`, 你可以替换掉目录层级到当前目录`echo_supervisord_conf > supervisord.conf` 并且通过`supervisor -c xxx.conf` 去指定配置文件的位置.

### supervisor配置一 ###

### 启动 ###

`supervisord supervisord.conf` 或者 `supervisord -c /etc/supervisor/supervisord.conf`  
通过supervisor去管理这些所有的进程, 包括收集日志文件
