centos8(linux): 安装使用supervisor管理laravel队列

一，什么是supervisor

Supervisor是一个进程控制系统，它使用户能够监视和控制类unix操作系统进程。
它通过提供基于配置或事件启动、停止和重新启动进程的机制，帮助管理应该在系统中连续运行的进程。
对于需要控制和监视Linux或其他类unix操作系统上多个进程的状态的开发人员和系统管理员来说，Supervisor非常有效。

二，安装/管理supervisor

1，用yum从命令行安装:

[root@blog ~]# yum install supervisor 

2，查看版本:

[lhdop@blog ~]$ supervisord --version
4.2.2

3,查看帮助:

[lhdop@blog ~]$ supervisord --help

[lhdop@blog ~]$ supervisorctl -h

4,查看服务状态:

[root@blog ~]# systemctl status supervisord.service
● supervisord.service - Process Monitoring and Control Daemon
   Loaded: loaded (/usr/lib/systemd/system/supervisord.service; disabled; vendor preset: disabled)
   Active: inactive (dead)

5，配置自启动

# 开机自启动
# systemctl enable supervisord 

6，启动服务

# 启动supervisord服务
# systemctl start supervisord 

7, 输出默认配置:

[lhdop@blog ~]$ echo_supervisord_conf 

8, 查看配置文件:

[lhdop@blog etc]$ more /etc/supervisord.conf

三，用supervisor管理php的laravel队列消费者

1,创建指定进程的配置文件

[root@blog ~]# cd /etc/supervisord.d/
[root@blog supervisord.d]# vi laravel-work.ini 

代码:

[root@blog supervisorlogs]# more /etc/supervisord.d/laravel-work.ini
[program:laravel-work]
process_name=%(program_name)s_%(process_num)02d
command=/usr/local/soft/php7/bin/php /data/work/laraveltest/dignews/artisan queue:work --daemon --quiet --delay=3 --sleep=3 --tries=1
autostart=true
autorestart=true
user=root
#numprocs=8
redirect_stderr=true
stdout_logfile=/data/logs/supervisorlogs/queue.log

2, 启动服务

[root@blog supervisord.d]# systemctl status supervisord.service
● supervisord.service - Process Monitoring and Control Daemon
   Loaded: loaded (/usr/lib/systemd/system/supervisord.service; disabled; vendor preset: disabled)
   Active: inactive (dead)
[root@blog supervisord.d]# systemctl start supervisord.service
[root@blog supervisord.d]# systemctl status supervisord.service
● supervisord.service - Process Monitoring and Control Daemon
   Loaded: loaded (/usr/lib/systemd/system/supervisord.service; disabled; vendor preset: disabled)
   Active: active (running) since Mon 2024-07-08 09:16:05 CST; 3s ago
  Process: 23525 ExecStart=/usr/bin/supervisord -c /etc/supervisord.conf (code=exited, status=0/SUCCESS)
 Main PID: 23528 (supervisord)
    Tasks: 2 (limit: 26213)

3，测试效果:

访问生产消息的controller后可以看到日志中的输出内容

[root@blog supervisord.d]# cd /data/logs/supervisorlogs/
[root@blog supervisorlogs]# more queue.log
