supervisor php-fpm,使用supervisor管理你的nginx、php-fpm进程

supervisor

前言:出处

零、supervisor是什么

Supervisor是用Python开发的一套通用的进程管理程序,能将一个普通的命令行进程变为后台daemon,并监控进程状态,异常退出时能自动重启。它是通过fork/exec的方式把这些被管理的进程当作supervisor的子进程来启动,这样只要在supervisor的配置文件中,把要管理的进程的可执行文件的路径写进去即可。也实现当子进程挂掉的时候,父进程可以准确获取子进程挂掉的信息的,可以选择是否自己启动和报警。

一、安装

apt -y install supervisor

yum -y install supervisor

二、配置

[unix_http_server]

file=/var/run/supervisor.sock

chmod=0700

[inet_http_server]

port=0.0.0.0:7020

username=root

password=xxxxxx

[supervisord]

logfile=/var/log/supervisor/supervisord.log

pidfile=/var/run/supervisord.pid

childlogdir=/var/log/supervisor

[rpcinterface:supervisor]

supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface

[supervisorctl]

serverurl=unix:///var/run/supervisor.sock

[include]

files = /etc/supervisor/conf.d/*.conf

三、管理服务

需要前台运行交于supervisor控制,原理是fork一个守护进程进行监控

program 标识,比如php-fpm,可以在后台supervisorctl中进行start/stop/restart操作

command 命令,需要加上sleep 1,防止进程还没退出supervisor就去检测,还挺好用

1、管理php-fpm

[program:php-fpm]

command=bash -c "sleep 1 && sudo /usr/local/php7.4/sbin/php-fpm"

process_name=%(program_name)s

autostart=true

autorestart=true

startretries=5

exitcodes=0,2,70

stopsignal=QUIT

stopwaitsecs=2

stdout_logfile=/var/log/supervisor/php-fpm.log

ps -ef|grep php-fpm

root 23034 22175 0 23:37 ? 00:00:00 sudo /usr/local/php7.4/sbin/php-fpm

root 23043 23034 0 23:37 ? 00:00:00 php-fpm: master process (/usr/local/php7.4/etc/php-fpm.conf)

www-data 23044 23043 0 23:37 ? 00:00:00 php-fpm: pool www

www-data 23045 23043 0 23:37 ? 00:00:00 php-fpm: pool www

2、管理nginx

[program:nginx]

command=bash -c "sleep 1 && sudo /usr/local/nginx/sbin/nginx -g 'daemon off;'"

process_name=%(program_name)s

autostart=true

autorestart=true

startretries=5

exitcodes=0,2,70

stopsignal=INT

stopwaitsecs=2

stdout_logfile=/var/log/supervisor/nginx.log

ps -ef|grep nginx

root 22613 22175 0 23:35 ? 00:00:00 sudo /usr/local/nginx/sbin/nginx -g daemon off;

root 22616 22613 0 23:35 ? 00:00:00 nginx: master process /usr/local/nginx/sbin/nginx -g daemon off;

www-data 22617 22616 0 23:35 ? 00:00:00 nginx: worker process

www-data 22618 22616 0 23:35 ? 00:00:00 nginx: worker process

www-data 22619 22616 0 23:35 ? 00:00:00 nginx: worker process

www-data 22620 22616 0 23:35 ? 00:00:00 nginx: worker process

3、管理Laravel job

[program:queue]

command=bash -c "cd /var/www/laravel && sudo /usr/bin/php artisan queue:work --timeout=60 --tries=3"

process_name=%(program_name)s

autostart=true

autorestart=true

startretries=5

exitcodes=0,2,70

stopsignal=INT

stopwaitsecs=2

stdout_logfile=/var/log/supervisor/queue.log

ps -ef|grep queue

root 30755 22175 0 Sep30 ? 00:00:00 sudo /usr/bin/php artisan queue:work --timeout=60 --tries=3

root 30756 30755 0 Sep30 ? 00:01:08 /usr/bin/php artisan queue:work --timeout=60 --tries=3

四、supervisorctl

supervisorctl

supervisor> status

nginx RUNNING pid 22613, uptime 0:03:40

php-fpm RUNNING pid 23034, uptime 0:01:43

supervisor> ?

default commands (type help ):

=====================================

add exit open reload restart start tail

avail fg pid remove shutdown status update

clear maintail quit reread signal stop version
