supervisor安装部署文档和管理实例

Supervisord是用Python实现的一款非常实用的进程管理工具,类似于monit(关于monit见我的博客:用monit监控系统关键进程),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


    如需要访问web控制界面,inet_http_server区段修改为:
    [inet_http_server]
    port=0.0.0.0:9001
    username=username ; 你的用户名
    password=password ; 你的密码


    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/www/python
    command = /bin/env 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
    #

    # allows its users to monitor and control a

    # description: Supervisor Server
    # processname: supervisord
     
    # Source init functions
    . /etc/init.d/functions
     
    RETVAL=0
    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 0 ] && touch ${lockfile}
    }
     
    stop()
    {
            echo -n $"Shutting down $prog: "
            killproc -p ${pidfile} /usr/bin/supervisord
            RETVAL=$?
            echo
            if [ $RETVAL -eq 0 ] ; 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=1
    numprocs=1
    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-2.6.16
    command=/usr/local/src/redis-2.6.16/src/redis-server redis.conf
     
    stdout_logfile=/tmp/redis_access.log
    stderr_logfile=/tmp/redis_error.log
    autostart=true
    autorestart=true
    startsecs=10
     
    ; Need to wait for currently executing tasks to finish at shutdown.
    ; Increase this if you have very long running tasks.
    stopwaitsecs = 600
     
    ; if rabbitmq is supervised, set its priority higher
    ; so it starts first
    priority=10


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 2;
    daemon off;
    events {
    #use epoll;
    worker_connections 1024;
    }
    http{
            #gzip on;
            #gzip_min_length  100;
            #gzip_buffers     4 16k;
            #gzip_http_version 1.0;
            #gzip_comp_level 2;
            #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  
                    server 127.0.0.1:8003;
                    server 127.0.0.1:8004;
                    server 127.0.0.1:8005;
                    server 127.0.0.1:8006;
     
            }
            server {
                    listen 8010;
                    location / {

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=10
     
    ; Need to wait for currently executing tasks to finish at shutdown.
    ; Increase this if you have very long running tasks.
    stopwaitsecs = 600
     
    ; if rabbitmq is supervised, set its priority higher
    ; so it starts first
    priority=55


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=2
    stdout_logfile=/tmp/celery_sendsms_access.log
    stderr_logfile=/tmp/celery_sendsms_error.log
    autostart=true
    autorestart=true
    startsecs=10
     
    ; Need to wait for currently executing tasks to finish at shutdown.
    ; Increase this if you have very long running tasks.
    stopwaitsecs = 600
     
    ; if rabbitmq is supervised, set its priority higher
    ; so it starts first
    priority=998


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=1
    stdout_logfile=/tmp/celeryworker.log
    stderr_logfile=/tmp/celeryworker.log
    autostart=true
    autorestart=true
    startsecs=10
     
    ; Need to wait for currently executing tasks to finish at shutdown.
    ; Increase this if you have very long running tasks.
    stopwaitsecs = 600
     
    ; if rabbitmq is supervised, set its priority higher
    ; so it starts first
    priority=15
     
    ;process_name = %(program_name)s-%(process_num)d
    ;numprocs=2


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=1
    stdout_logfile=/tmp/celerybeat.log
    stderr_logfile=/tmp/celerybeat.log
    autostart=true
    autorestart=true
    startsecs=10
     
    ; Need to wait for currently executing tasks to finish at shutdown.
    ; Increase this if you have very long running tasks.
    stopwaitsecs = 600
     
    ; if rabbitmq is supervised, set its priority higher
    ; so it starts first
    priority=14
     
    ;process_name = %(program_name)s-%(process_num)d
    ;numprocs=2



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-8003]
    directory=/usr/local/workspace_eclipse3.7.2/venus
    command=/usr/local/bin/python main.py --port=8003
    stdout_logfile=/tmp/venus_8003.log
    stderr_logfile=/tmp/venus_8003.log
    autostart=true
    autorestart=true
    priority=50
     
    [program:venus-8004]
    directory=/usr/local/workspace_eclipse3.7.2/venus
    command=/usr/local/bin/python main.py --port=8004
    stdout_logfile=/tmp/venus_8004.log
    stderr_logfile=/tmp/venus_8004.log
    autostart=true
    autorestart=true
    priority=51
     
    [program:venus-8005]
    directory=/usr/local/workspace_eclipse3.7.2/venus
    command=/usr/local/bin/python main.py --port=8005
    stdout_logfile=/tmp/venus_8005.log
    stderr_logfile=/tmp/venus_8005.log
    autostart=true
    autorestart=true
    priority=52
     
    [program:venus-8006]
    directory=/usr/local/workspace_eclipse3.7.2/venus
    command=/usr/local/bin/python main.py --port=8006
    stdout_logfile=/tmp/venus_8006.log
    stderr_logfile=/tmp/venus_8006.log
    autostart=true
    autorestart=true
    priority=53
    ~                               


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=10
     
    ; Need to wait for currently executing tasks to finish at shutdown.
    ; Increase this if you have very long running tasks.
    stopwaitsecs = 600
     
    ; if rabbitmq is supervised, set its priority higher
    ; so it starts first
    priority=21



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。
