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
#
# Supervisor is a client/server system that
# allows its users to monitor and control a
# number of processes on UNIX-like operating
# systems.
#
# chkconfig: - 64 36
# 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

Ubuntu环境下：

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 {

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

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。
