Supervisord是用Python实现的一款非常实用的进程管理工具，类似于monit，monit和supervisord的一个比较大的差异是supervisord管理的进程必须由supervisord来启动，monit可以管理已经在运行的程序；supervisord还要求管理的程序是非daemon程序，supervisord会帮你把它转成daemon程序，因此如果用supervisord来管理nginx的话，必须在nginx的配置文件里添加一行设置daemon off让nginx以非daemon方式启动。(此段话引用链接：http://feilong.me/2011/03/monitor-processes-with-supervisord)

注意：如果用supervisorctlstart nginx启动nginx显示错误nginx: ERROR(abnormal termination)，查看日志说是nginx已经启动，这就是因为nginx本身是daemon程序，要在nginx的配置文件中把它转为非daemon程序.

1.Supervisor安装：

 # 安装

 easy_install supervisor

也可采用离线安装的方式：

安装python
安装meld3-0.6.8.tar.gz

安装elementtree-1.2.6-20050316.tar.gz
安装supervisor-3.0a12.tar.gz

官方安装文档：
http://supervisord.org/installing.html

依赖软件：

 setuptools (latest) from http://pypi.python.org/pypi/setuptools.

 meld3 (latest) from http://www.plope.com/software/meld3/.

 elementtree (latest) from http://effbot.org/downloads#elementtree.  
2.生成默认配置文件：
 # 生成默认配置文件

 echo_supervisord_conf > /etc/supervisord.conf

 mkdir /etc/supervisord.conf.d

3.修改配置文件

 include区段修改为：

 [include]

 files = /etc/supervisord.conf.d/*.conf  
 每个需要管理的进程分别写在一个文件里面，放在/etc/supervisord.conf.d/目录下，便于管理。例如：test.conf

 [program:sqlparse]

 directory = /var/local/python

 command = /use/bin python test.py  


4.把supervisord服务设为开机自启动，把下面程序复制下来生成supervisord文件放到/etc/init.d/目录下面：


CentOS环境下：

 #

 # /etc/rc.d/init.d/supervisord

 # allows its users to monitor and control a

 # number of processes on UNIX-like operating

 # systems.

 # Source init functions

 . /etc/init.d/functions  

 RETVAL=

 prog="supervisord"

 pidfile="/tmp/supervisord.pid"

 lockfile="/var/lock/subsys/supervisord"  

 start()

 {

         echo -n $"Starting $prog: "

         daemon --pidfile $pidfile supervisord -c /etc/supervisord.conf

         RETVAL=$?

         echo

         [ $RETVAL -eq  ] && touch ${lockfile}

 }  

 stop()

 {

         echo -n $"Shutting down $prog: "

         killproc -p ${pidfile} /usr/bin/supervisord

         RETVAL=$?

         echo

         if [ $RETVAL -eq  ] ; then

                 rm -f ${lockfile} ${pidfile}

         fi

 }  

 case "$1" in  

   start)

     start

   ;;  

   stop)

     stop

   ;;  

   status)

         status $prog

   ;;  

   restart)

     stop

     start

   ;;  

   *)

     echo "Usage: $0 {start|stop|restart|status}"

   ;;  

 esac

用root用户执行下面命令把supervisord服务设为开机自启动：


CentOS系统下：




 chmod +x /etc/init.d/supervisord

 chkconfig supervisord on

 service supervisord start




Ubuntu系统下：




 chmod +x /etc/init.d/supervisord

 update-rc.d supervisord defaults




5.supervisord管理


Supervisord安装完成后有两个可用的命令行supervisor和supervisorctl，命令使用解释如下：


  • supervisord，初始启动Supervisord，启动、管理配置中设置的进程。
    • 

  • supervisorctl stop programxxx，停止某一个进程(programxxx)，programxxx为[program:chatdemon]里配置的值，这个示例就是chatdemon。
    • 

  • supervisorctl start programxxx，启动某个进程
    • 

  • supervisorctl restart programxxx，重启某个进程
    • 

  • supervisorctl stop groupworker: ，重启所有属于名为groupworker这个分组的进程(start,restart同理)
    • 

  • 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 reload，载入最新的配置文件，停止原有进程并按新的配置启动、管理所有进程。
    • 

  • 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。
    • 

  • 注意：显示用stop停止掉的进程，用reload或者update都不会自动重启。

7.管理实例


7.1.测试一个简单的python程序：


在/etc/supervisord.conf.d/目录下生成testsupervisor.conf文件




 [program:testsupervisor]

 directory = /opt/testsupervisor

 command = /usr/local/bin/python testsupervisor.py

 priority=

 numprocs=

 autostart=true

 autorestart=true  




directory表示testsupervisor.py所在的工作目录


command表示执行的命令，注意python要用绝对路径：/usr/local/bin/python


priority表示优先级，用supervisord管理的程序会按优先级从高到低依次启动，数字越多，优先级越高


autostart表示自动启动


autorestart表示自动重启


7.2.用supervisord管理 redis程序：


在/etc/supervisord.conf.d/目录下生成redis.conf文件






 [program:redis]

 directory=/usr/local/src/redis-2.6.

 command=/usr/local/src/redis-2.6./src/redis-server redis.conf  

 stdout_logfile=/tmp/redis_access.log

 stderr_logfile=/tmp/redis_error.log

 autostart=true

 autorestart=true

 startsecs=  

 ; Need to wait for currently executing tasks to finish at shutdown.

 ; Increase this if you have very long running tasks.

 stopwaitsecs =   

 ; if rabbitmq is supervised, set its priority higher

 ; so it starts first

 priority=  






7.3.用supervisord管理nginx程序，因为nginx默认就是以daemon方式启动的，所以如果用supervisord来管理nginx的话，必须在nginx的配置文件里添加一行设置daemon off让nginx以非daemon方式启动。(supervisord还要求管理的程序是非daemon程序，supervisord会帮你把它转成daemon程序)


在/usr/local/nginx/conf/目录下面修改nginx.conf文件：






 worker_processes ;

 daemon off;

 events {

 #use epoll;

 worker_connections ;

 }

 http{

         #gzip on;

         #gzip_min_length  ;

         #gzip_vary on;  

         upstream 192.168.56.11 {

 startsecs=  

 ; Need to wait for currently executing tasks to finish at shutdown.

 ; Increase this if you have very long running tasks.

 stopwaitsecs =   

 ; if rabbitmq is supervised, set its priority higher

 ; so it starts first

 priority=  

 ;process_name = %(program_name)s-%(process_num)d

 ;numprocs=  






在/etc/supervisord.conf.d/目录下生成celeryd_beat.conf文件,django环境下的心跳服务






 ; ==============================================

 ;  celery worker supervisor example for Django

 ; if rabbitmq is supervised, set its priority higher

 ; so it starts first

 priority=  

 ;process_name = %(program_name)s-%(process_num)d

 ;numprocs=  






 


7.6.用supervisord管理venus服务(启了四个进程):


在/etc/supervisord.conf.d/目录下生成venux.conf文件






 [program:venus-]

 directory=/usr/local/workspace_eclipse3.7.2/venus

 command=/usr/local/bin/python main.py --port=

 stdout_logfile=/tmp/venus_8003.log

 stderr_logfile=/tmp/venus_8003.log

 autostart=true

 autorestart=true

 priority=  

 [program:venus-]

 directory=/usr/local/workspace_eclipse3.7.2/venus

 command=/usr/local/bin/python main.py --port=

 stdout_logfile=/tmp/venus_8004.log

 stderr_logfile=/tmp/venus_8004.log

 autostart=true

 autorestart=true

 priority=  

 [program:venus-]

 directory=/usr/local/workspace_eclipse3.7.2/venus

 command=/usr/local/bin/python main.py --port=

 stdout_logfile=/tmp/venus_8005.log

 stderr_logfile=/tmp/venus_8005.log

 autostart=true

 autorestart=true

 priority=  

 [program:venus-]

 directory=/usr/local/workspace_eclipse3.7.2/venus

 command=/usr/local/bin/python main.py --port=

 command=/usr/local/bin/python receiver_cmpp.py  

 stdout_logfile=/tmp/receiver_cmpp.log

 stderr_logfile=/tmp/receiver_cmpp.log

 autostart=true

 autorestart=true

 startsecs=  

 ; Need to wait for currently executing tasks to finish at shutdown.

 ; Increase this if you have very long running tasks.

 stopwaitsecs =   

 ; if rabbitmq is supervised, set its priority higher

 ; so it starts first

 priority=  






在/etc/supervisord.conf.d/目录下添加新的配置文件后，执行命令：






 supervisorctl update  






就会把新添加的服务启动起来，且不会影响正在运行的 服务。
