Supervisor 安装与配置

[Supervisor]

http://supervisord.org/

[Python]

如果没有,自己去装吧,一般 linux 自带了.

[easy_install]

[root@vm source]# wget https://bootstrap.pypa.io/ez_setup.py -O - | python

[安装superviosr]

[root@vm source]# easy_install supervisor

[状态]

[root@vm source]# python
Python 2.6.6 (r266:84292, Jan 22 2014, 09:37:14) 
[GCC 4.4.7 20120313 (Red Hat 4.4.7-4)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import supervisor
>>>

[配置文件]

[root@vm source]# echo_supervisord_conf > /etc/supervisord.conf

[监视一个程序]

; The [include] section can just contain the "files" setting.  This
; setting can list multiple files (separated by whitespace or
; newlines).  It can also contain wildcards.  The filenames are
; interpreted as relative to this file.  Included files *cannot*
; include files themselves.

[include] /**我是注释，一定要把前面的分号;去掉，不然不会开启include功能，太傻了**/
files = /etc/supervisor/*.ini

在 /etc/supervisor/ 目录下建立 redis.ini 文件

[program:redis]
command=/usr/bin/redis-server /usr/local/redis/redis.conf
autorstart=true
autorestart=true
stdout_logfile=/tmp/supervisor.log

[Web配置]

[inet_http_server]         ; inet (TCP) server disabled by default
port=*:9001        ; (ip_address:port specifier, *:port for all iface)
;username=user              ; (default is no username (open server))
;password=123               ; (default is no password (open server))

如果配置了用户名和密码，就需要输入用户名和密码才能进入web界面。

[启动supervisord]

[root@vm source]# supervisord

可能会输出一堆信息出来

/usr/lib/python2.6/site-packages/supervisor-3.1.3-py2.6.egg/supervisor/options.py:296: UserWarning: Supervisord is running as root and it is searching for its configuration file in default locations (including its current working directory); you probably want to specify a "-c" argument specifying an absolute path to a configuration file for improved security.
  'Supervisord is running as root and it is searching '
/usr/lib/python2.6/site-packages/supervisor-3.1.3-py2.6.egg/supervisor/options.py:383: DeprecationWarning: Parameters to load are deprecated.  Call .resolve and .require separately.
  return pkg_resources.EntryPoint.parse("x="+spec).load(False)

不用管它

  [root@vm source]# ps -ef ｜grep supervisord
  root     20041     1  0 03:21 ?        00:00:00 /usr/bin/python /usr/bin/supervisord

  [root@vm source]# ps -ef| grep redis
  root     20074 20073  0 03:23 ?        00:00:00 /usr/bin/redis-server *:6379

有上述进程，就表明成功了。

[WEB管理界面]

[命令行管理工具]

[root@vm source]# supervisorctl status
redis                            RUNNING   pid 20074, uptime 0:13:25
