supervisor 安装和配置

supervisor 是由python语言编写、基于linux操作系统的一款服务器管理工具，用以监控服务器的运行，发现问题能立即自动预警及自动重启等功能。

1.首先必须先安装好python环境，linux已经自带python，建议安装python2.7.5.先在终端输入python查看python版本，能正常显示则表明没问题，输入exit()退出python环境。

root@debian-lege-pro:~# python
Python 2.7.3 (default, Mar 13 2014, 11:03:55) 
[GCC 4.7.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>>

2.在终端输入 easy_install supervisor 并回车，linux会自动联网并下载supervisor源码解压并安装。

root@debian-lege-pro:~# easy_install supervisor

3.安装成功后显示finished,我们再次进行python环境，输入import supervisor ，如果没提示错误则表示安装成功。

root@debian-lege-pro:~# python
Python 2.7.3 (default, Mar 13 2014, 11:03:55) 
[GCC 4.7.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import supervisor
>>>

4.接下来是对supervisor配置,首先我们要生成配置文件，在shell终端输入 echosupervisordconf > /etc/supervisord.conf

root@debian-lege-pro:~# echo_supervisord_conf > /etc/supervisord.conf

5.接着编辑配置文件 vim /etc/supervisord.conf 在最底部添加如下参数 [program:app] command=python /usr/local/app/web/app.py autorstart=true stdout_logfile=/tmp/hello.log 编辑完成后保存退出

root@debian-lege-pro:~# vim /etc/supervisord.conf
....
[program:app]
command=python /usr/local/app/web/app.py
autorstart=true
stdout_logfile=/tmp/hello.log

6.ps命令查看运行情况，应用现在已经自动运行了。

root@debian-lege-pro:~# ps -ef | grep super
root 12  2  0 03:15 ?00:00:00 [sync_supers]
root   3625   3138  0 04:40 pts/000:00:00 grep super
