supervisor安装部署和使用实例

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：

 #!/bin/sh
 #
 # /etc/rc.d/init.d/supervisord
 #
 # Supervisor is a client/server system that
 # allows its users to monitor and control a
 # number of processes on UNIX-like operating
 # systems.
 #
 # chkconfig: -

 # 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_buffers      16k;
         #gzip_http_version 1.0;
         #gzip_comp_level ;
         #gzip_types       text/plain application/x-javascript text/css application/xml;
         #gzip_vary on;  
 
         upstream 192.168.56.11 {
         #这里指定多个源服务器，ip:端口,80端口的话可写可不写

 }  

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

 [program:nginx]
 command=/usr/local/nginx/sbin/nginx  
 
 stdout_logfile=/tmp/nginx.log
 stderr_logfile=/tmp/nginx.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=  

7.4.用supervisord管理celery服务(python环境下)：

celery官方链接：https://github.com/celery/celery/tree/3.0/extra/supervisord

在/etc/supervisord.conf.d/目录下生成celeryd.conf文件,启了两个worker,配置文件中要注意celeryconfig.py的路径:

 ; ============================
 ;  celeryd supervisor example
 ; ============================  
 
 ; NOTE: If you're using Django, you shouldn't use this file.
 ; Use
 ; http://github.com/celery/django-celery/tree/master/extra/supervisord/celeryd.conf
 ; instead!  
 
 [program:celery]
 command=/usr/local/bin/celery worker --loglevel INFO --queues=low_send_task_queue,high_send_task_queue  
 
 process_name = %(program_name)s-%(process_num)d  
 
 ; Set PYTHONPATH to the directory containing celeryconfig.py
 environment=PYTHONPATH=/usr/local/workspace_eclipse3.7.2/venus  
 
 directory=/usr/local/workspace_eclipse3.7.2/venus  
 
 numprocs=
 stdout_logfile=/tmp/celery_sendsms_access.log
 stderr_logfile=/tmp/celery_sendsms_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=  

7.5.用supervisord管理celery服务(django环境下)：

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

 ; ==============================================
 ;  celery worker supervisor example for Django
 ; ==============================================  
 
 [program:celeryworker]
 command=/usr/local/bin/python manage.py celery worker --loglevel=INFO --queues=db_write_back_queue
 directory=/usr/local/workspace_eclipse3.7.2/sms_web  
 
 numprocs=
 stdout_logfile=/tmp/celeryworker.log
 stderr_logfile=/tmp/celeryworker.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=  
 
 ;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
 ; ==============================================  
 
 [program:celerybeat]
 command=/usr/local/bin/python manage.py celery beat -s /var/log/sms_web/celerybeat-schedule --loglevel=INFO
 directory=/usr/local/workspace_eclipse3.7.2/sms_web  
 
 numprocs=
 stdout_logfile=/tmp/celerybeat.log
 stderr_logfile=/tmp/celerybeat.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=  
 
 ;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=
 stdout_logfile=/tmp/venus_8006.log
 stderr_logfile=/tmp/venus_8006.log
 autostart=true
 autorestart=true
 priority=
 ~        

7.7.用supervisord管理接收短信的服务：

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

 [program:receiver-cmpp]
 directory=/usr/local/workspace_eclipse3.7.2/sms_tool
 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。
