  • 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:

    1 # 安装  
    2 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:

    1 setuptools (latest) from http://pypi.python.org/pypi/setuptools.  
    2 meld3 (latest) from http://www.plope.com/software/meld3/.  
    3 elementtree (latest) from http://effbot.org/downloads#elementtree.  
    2.生成默认配置文件:
    1 # 生成默认配置文件  
    2 echo_supervisord_conf > /etc/supervisord.conf  
    3 mkdir /etc/supervisord.conf.d  

    3.修改配置文件

    1 include区段修改为:  
    2 [include]  
    3 files = /etc/supervisord.conf.d/*.conf  
    1 如需要访问web控制界面,inet_http_server区段修改为:  
    2 [inet_http_server]  
    3 port=0.0.0.0:9001  
    4 username=username ; 你的用户名  
    5 password=password ; 你的密码  
     
    1 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  
    2 [program:sqlparse]  
    3 directory = /var/local/python  
    4 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:

    29 }  
    30   
    31 stop()  
    32 {  
    33         echo -n $"Shutting down $prog: "  
    34         killproc -p ${pidfile} /usr/bin/supervisord  
    35         RETVAL=$?  
    36         echo  
    37         if [ $RETVAL -eq 0 ] ; then  
    38                 rm -f ${lockfile} ${pidfile}  
    39         fi  
    40 }  
    41   
    42 case "$1" in  
    43   
    44   start)  
    45     start  
    46   ;;  
    47   
    48   stop)  
    49     stop  
    50   ;;  
    51   
    52   status)  
    53         status $prog  
    54   ;;  
    55   
    56   restart)  
    57     stop  
    58     start  
    59   ;;  
    60   
    61   *)  
    62     echo "Usage: $0 {start|stop|restart|status}"  
    63   ;;  
    64   
    65 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:

    1 chmod +x /etc/init.d/supervisord  
    2 chkconfig supervisord on  
    3 service supervisord start


    Ubuntu系统下:

    1 chmod +x /etc/init.d/supervisord  
    2 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。

    6.supervisord的配置文件(/etc/supervisord.conf)

    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

    1 [program:testsupervisor]  
    2 directory = /opt/testsupervisor  
    3 command = /usr/local/bin/python testsupervisor.py  
    4 priority=1  
    5 numprocs=1  
    6 autostart=true  
    7 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

     1 [program:redis]  
     2 directory=/usr/local/src/redis-2.6.16  
     3 command=/usr/local/src/redis-2.6.16/src/redis-server redis.conf  
     4   
     5 stdout_logfile=/tmp/redis_access.log  
     6 stderr_logfile=/tmp/redis_error.log  
     7 autostart=true  
     8 autorestart=true  
     9 startsecs=10  
    10   
    11 ; Need to wait for currently executing tasks to finish at shutdown.  
    12 ; Increase this if you have very long running tasks.  
    13 stopwaitsecs = 600  
    14   
    15 ; if rabbitmq is supervised, set its priority higher  
    16 ; so it starts first  
    17 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:

     
     1 worker_processes 2;  
     2 daemon off;  
     3 events {  
     4 #use epoll;  
     5 worker_connections 1024;  
     6 }  
     7 http{  
     8         #gzip on;  
     9         #gzip_min_length  100;  
    10         #gzip_buffers     4 16k;  
    11         #gzip_http_version 1.0;  
    12         #gzip_comp_level 2;  
    13         #gzip_types       text/plain application/x-javascript text/css application/xml;  
    14         #gzip_vary on;  
    15   
    16         upstream 192.168.56.11 {  
    17         #这里指定多个源服务器,ip:端口,80端口的话可写可不写    
    18                 server 127.0.0.1:8003;  
    19                 server 127.0.0.1:8004;

    24         server {  
    25                 listen 8010;  
    26                 location / {  
    27                         #rewrite ^/smmp/servletsendmoremsg.do$ /send last;

    32   
    33                 }  
    34   
    35         }  
    36   
    37 #       server {  
    38 #               listen 443;

    47 #               ssl_prefer_server_ciphers   on;  
    48 #               location / {  
    49 #                        proxy_redirect off;

    55 #                 
    56 #       }    
    57 }  

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

     1 [program:nginx]  
     2 command=/usr/local/nginx/sbin/nginx  
     3   
     4 stdout_logfile=/tmp/nginx.log  
     5 stderr_logfile=/tmp/nginx.log  
     6 autostart=true  
     7 autorestart=true  
     8 startsecs=10  
     9   
    10 ; Need to wait for currently executing tasks to finish at shutdown.  
    11 ; Increase this if you have very long running tasks.  
    12 stopwaitsecs = 600  
    13   
    14 ; if rabbitmq is supervised, set its priority higher  
    15 ; so it starts first  
    16 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:

     1 ; ============================  
     2 ;  celeryd supervisor example  
     3 ; ============================  
     4   
     5 ; NOTE: If you're using Django, you shouldn't use this file.

    31 ; if rabbitmq is supervised, set its priority higher  
    32 ; so it starts first  
    33 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

     1 ; ==============================================  
     2 ;  celery worker supervisor example for Django  
     3 ; ==============================================  
     4   
     5 [program:celeryworker]  
     6 command=/usr/local/bin/python manage.py celery worker --loglevel=INFO --queues=db_write_back_queue

    22 priority=14  
    23   
    24 ;process_name = %(program_name)s-%(process_num)d  
    25 ;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

     1 [program:venus-8003]  
     2 directory=/usr/local/workspace_eclipse3.7.2/venus  
     3 command=/usr/local/bin/python main.py --port=8003

    12 command=/usr/local/bin/python main.py --port=8004  
    13 stdout_logfile=/tmp/venus_8004.log  
    14 stderr_logfile=/tmp/venus_8004.log  
    15 autostart=true  
    16 autorestart=true  
    17 priority=51  
    18   
    19 [program:venus-8005]  
    20 directory=/usr/local/workspace_eclipse3.7.2/venus  
    21 command=/usr/local/bin/python main.py --port=8005  
    22 stdout_logfile=/tmp/venus_8005.log  
    23 stderr_logfile=/tmp/venus_8005.log  
    24 autostart=true  
    25 autorestart=true  
    26 priority=52  
    27   
    28 [program:venus-8006]  
    29 directory=/usr/local/workspace_eclipse3.7.2/venus  
    30 command=/usr/local/bin/python main.py --port=8006  
    31 stdout_logfile=/tmp/venus_8006.log  
    32 stderr_logfile=/tmp/venus_8006.log  
    33 autostart=true  
    34 autorestart=true  
    35 priority=53  
    36 ~        

    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

     1 [program:receiver-cmpp]  
     2 directory=/usr/local/workspace_eclipse3.7.2/sms_tool  
     3 command=/usr/local/bin/python receiver_cmpp.py  
     4   
     5 stdout_logfile=/tmp/receiver_cmpp.log  
     6 stderr_logfile=/tmp/receiver_cmpp.log  
     7 autostart=true  
     8 autorestart=true  
     9 startsecs=10  
    10   
    11 ; Need to wait for currently executing tasks to finish at shutdown.  
    12 ; Increase this if you have very long running tasks.  
    13 stopwaitsecs = 600  
    14   
    15 ; if rabbitmq is supervised, set its priority higher  
    16 ; so it starts first  
    17 priority=21  

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

    1 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。
