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
