supervisor安装部署和使用实例

發(fā)布時(shí)間：2023/12/31 编程问答 28 豆豆

生活随笔收集整理的這篇文章主要介紹了 supervisor安装部署和使用实例小編覺(jué)得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.

Supervisord是用Python實(shí)現(xiàn)的一款非常實(shí)用的進(jìn)程管理工具，類(lèi)似于monit，monit和supervisord的一個(gè)比較大的差異是supervisord管理的進(jìn)程必須由supervisord來(lái)啟動(dòng)，monit可以管理已經(jīng)在運(yùn)行的程序；supervisord還要求管理的程序是非daemon程序，supervisord會(huì)幫你把它轉(zhuǎn)成daemon程序，因此如果用supervisord來(lái)管理nginx的話，必須在nginx的配置文件里添加一行設(shè)置daemon off讓nginx以非daemon方式啟動(dòng)。(此段話引用鏈接：http://feilong.me/2011/03/monitor-processes-with-supervisord)

注意：如果用supervisorctlstart nginx啟動(dòng)nginx顯示錯(cuò)誤nginx: ERROR(abnormal termination)，查看日志說(shuō)是nginx已經(jīng)啟動(dòng)，這就是因?yàn)閚ginx本身是daemon程序，要在nginx的配置文件中把它轉(zhuǎn)為非daemon程序.

1.Supervisor安裝：

1 # 安裝 2 easy_install supervisor

也可采用離線安裝的方式：

安裝python
安裝meld3-0.6.8.tar.gz

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

官方安裝文檔：
http://supervisord.org/installing.html

依賴(lài)軟件：

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.生成默認(rèn)配置文件： 1 # 生成默認(rèn)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區(qū)段修改為： 2 [include] 3 files = /etc/supervisord.conf.d/*.conf 1 如需要訪問(wèn)web控制界面，inet_http_server區(qū)段修改為： 2 [inet_http_server] 3 port=0.0.0.0:9001 4 username=username ; 你的用戶名 5 password=password ; 你的密碼 1 每個(gè)需要管理的進(jìn)程分別寫(xiě)在一個(gè)文件里面，放在/etc/supervisord.conf.d/目錄下，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服務(wù)設(shè)為開(kāi)機(jī)自啟動(dòng)，把下面程序復(fù)制下來(lái)生成supervisord文件放到/etc/init.d/目錄下面：

CentOS環(huán)境下：

1 #!/bin/sh 2 # 3 # /etc/rc.d/init.d/supervisord 4 # 5 # Supervisor is a client/server system that 6 # allows its users to monitor and control a 7 # number of processes on UNIX-like operating 8 # systems. 9 # 10 # chkconfig: - 64 36 11 # description: Supervisor Server 12 # processname: supervisord 13 14 # Source init functions 15 . /etc/init.d/functions 16 17 RETVAL=0 18 prog="supervisord" 19 pidfile="/tmp/supervisord.pid" 20 lockfile="/var/lock/subsys/supervisord" 21 22 start() 23 { 24 echo -n $"Starting $prog: " 25 daemon --pidfile $pidfile supervisord -c /etc/supervisord.conf 26 RETVAL=$? 27 echo 28 [ $RETVAL -eq 0 ] && touch ${lockfile} 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用戶執(zhí)行下面命令把supervisord服務(wù)設(shè)為開(kāi)機(jī)自啟動(dòng)：

CentOS系統(tǒng)下：

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

Ubuntu系統(tǒng)下：

1 chmod +x /etc/init.d/supervisord 2 update-rc.d supervisord defaults

5.supervisord管理

Supervisord安裝完成后有兩個(gè)可用的命令行supervisor和supervisorctl，命令使用解釋如下：

supervisord，初始啟動(dòng)Supervisord，啟動(dòng)、管理配置中設(shè)置的進(jìn)程。
supervisorctl stop programxxx，停止某一個(gè)進(jìn)程(programxxx)，programxxx為[program:chatdemon]里配置的值，這個(gè)示例就是chatdemon。
supervisorctl start programxxx，啟動(dòng)某個(gè)進(jìn)程
supervisorctl restart programxxx，重啟某個(gè)進(jìn)程
supervisorctl stop groupworker: ，重啟所有屬于名為groupworker這個(gè)分組的進(jìn)程(start,restart同理)
supervisorctl stop all，停止全部進(jìn)程，注：start、restart、stop都不會(huì)載入最新的配置文件。
supervisorctl reload，載入最新的配置文件，停止原有進(jìn)程并按新的配置啟動(dòng)、管理所有進(jìn)程。
supervisorctl update，根據(jù)最新的配置文件，啟動(dòng)新配置或有改動(dòng)的進(jìn)程，配置沒(méi)有改動(dòng)的進(jìn)程不會(huì)受影響而重啟。
注意：顯示用stop停止掉的進(jìn)程，用reload或者update都不會(huì)自動(dòng)重啟。

7.管理實(shí)例

7.1.測(cè)試一個(gè)簡(jiǎn)單的python程序：

在/etc/supervisord.conf.d/目錄下生成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所在的工作目錄

command表示執(zhí)行的命令，注意python要用絕對(duì)路徑：/usr/local/bin/python

priority表示優(yōu)先級(jí)，用supervisord管理的程序會(huì)按優(yōu)先級(jí)從高到低依次啟動(dòng)，數(shù)字越多，優(yōu)先級(jí)越高

autostart表示自動(dòng)啟動(dòng)

autorestart表示自動(dòng)重啟

7.2.用supervisord管理 redis程序：

在/etc/supervisord.conf.d/目錄下生成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?yàn)閚ginx默認(rèn)就是以daemon方式啟動(dòng)的，所以如果用supervisord來(lái)管理nginx的話，必須在nginx的配置文件里添加一行設(shè)置daemon off讓nginx以非daemon方式啟動(dòng)。(supervisord還要求管理的程序是非daemon程序，supervisord會(huì)幫你把它轉(zhuǎn)成daemon程序)

在/usr/local/nginx/conf/目錄下面修改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 #這里指定多個(gè)源服務(wù)器，ip:端口,80端口的話可寫(xiě)可不寫(xiě) 18 server 127.0.0.1:8003; 19 server 127.0.0.1:8004; 20 server 127.0.0.1:8005; 21 server 127.0.0.1:8006; 22 23 } 24 server { 25 listen 8010; 26 location / { 27 #rewrite ^/smmp/servletsendmoremsg\.do$ /send last; 28 proxy_redirect off; 29 proxy_set_header Host $host; 30 proxy_set_header X-Forwarded-For $remote_addr; 31 proxy_pass http://192.168.56.11; 32 33 } 34 35 } 36 37 # server { 38 # listen 443; 39 # ssl on; 40 # ssl_certificate server.crt; 41 # ssl_certificate_key server.key; 42 # 43 # ssl_session_timeout 5m; 44 # 45 # ssl_protocols SSLv2 SSLv3 TLSv1; 46 # ssl_ciphers HIGH:!aNULL:!MD5; 47 # ssl_prefer_server_ciphers on; 48 # location / { 49 # proxy_redirect off; 50 # proxy_set_header Host $host; 51 # proxy_set_header X-Forwarded-For $remote_addr; 52 # proxy_pass http://192.168.56.11; 53 # 54 # } 55 # 56 # } 57 }

在/etc/supervisord.conf.d/目錄下生成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服務(wù)(python環(huán)境下)：

在/etc/supervisord.conf.d/目錄下生成celeryd.conf文件,啟了兩個(gè)worker,配置文件中要注意celeryconfig.py的路徑:

1 ; ============================ 2 ; celeryd supervisor example 3 ; ============================ 4 5 ; NOTE: If you're using Django, you shouldn't use this file. 6 ; Use 7 ; http://github.com/celery/django-celery/tree/master/extra/supervisord/celeryd.conf 8 ; instead! 9 10 [program:celery] 11 command=/usr/local/bin/celery worker --loglevel INFO --queues=low_send_task_queue,high_send_task_queue 12 13 process_name = %(program_name)s-%(process_num)d 14 15 ; Set PYTHONPATH to the directory containing celeryconfig.py 16 environment=PYTHONPATH=/usr/local/workspace_eclipse3.7.2/venus 17 18 directory=/usr/local/workspace_eclipse3.7.2/venus 19 20 numprocs=2 21 stdout_logfile=/tmp/celery_sendsms_access.log 22 stderr_logfile=/tmp/celery_sendsms_error.log 23 autostart=true 24 autorestart=true 25 startsecs=10 26 27 ; Need to wait for currently executing tasks to finish at shutdown. 28 ; Increase this if you have very long running tasks. 29 stopwaitsecs = 600 30 31 ; if rabbitmq is supervised, set its priority higher 32 ; so it starts first 33 priority=998

7.5.用supervisord管理celery服務(wù)(django環(huán)境下)：

在/etc/supervisord.conf.d/目錄下生成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 7 directory=/usr/local/workspace_eclipse3.7.2/sms_web 8 9 numprocs=1 10 stdout_logfile=/tmp/celeryworker.log 11 stderr_logfile=/tmp/celeryworker.log 12 autostart=true 13 autorestart=true 14 startsecs=10 15 16 ; Need to wait for currently executing tasks to finish at shutdown. 17 ; Increase this if you have very long running tasks. 18 stopwaitsecs = 600 19 20 ; if rabbitmq is supervised, set its priority higher 21 ; so it starts first 22 priority=15 23 24 ;process_name = %(program_name)s-%(process_num)d 25 ;numprocs=2

在/etc/supervisord.conf.d/目錄下生成celeryd_beat.conf文件,django環(huán)境下的心跳服務(wù)

1 ; ============================================== 2 ; celery worker supervisor example for Django 3 ; ============================================== 4 5 [program:celerybeat] 6 command=/usr/local/bin/python manage.py celery beat -s /var/log/sms_web/celerybeat-schedule --loglevel=INFO 7 directory=/usr/local/workspace_eclipse3.7.2/sms_web 8 9 numprocs=1 10 stdout_logfile=/tmp/celerybeat.log 11 stderr_logfile=/tmp/celerybeat.log 12 autostart=true 13 autorestart=true 14 startsecs=10 15 16 ; Need to wait for currently executing tasks to finish at shutdown. 17 ; Increase this if you have very long running tasks. 18 stopwaitsecs = 600 19 20 ; if rabbitmq is supervised, set its priority higher 21 ; so it starts first 22 priority=14 23 24 ;process_name = %(program_name)s-%(process_num)d 25 ;numprocs=2 ?

7.6.用supervisord管理venus服務(wù)(啟了四個(gè)進(jìn)程):

在/etc/supervisord.conf.d/目錄下生成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 4 stdout_logfile=/tmp/venus_8003.log 5 stderr_logfile=/tmp/venus_8003.log 6 autostart=true 7 autorestart=true 8 priority=50 9 10 [program:venus-8004] 11 directory=/usr/local/workspace_eclipse3.7.2/venus 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管理接收短信的服務(wù)：

在/etc/supervisord.conf.d/目錄下生成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/目錄下添加新的配置文件后，執(zhí)行命令：

1 supervisorctl update

就會(huì)把新添加的服務(wù)啟動(dòng)起來(lái)，且不會(huì)影響正在運(yùn)行的服務(wù)。?
