使用Supervisor监管LaravelS

Supervisor 是一个 Python 写的进程管理工具，有时一个进程需要在后台运行，并且意外挂掉后能够自动重启，就需要这么一个管理进程的工具。

安装

• 使用 pip 工具进行安装：

[root@caoxl ~]# sudo pip install supervisor

• Ubuntu 系统使用 apt-get

sudo apt-get install supervisor

• 检查是否安装完成

[root@caoxl ~]# supervisord --help
supervisord -- run a set of applications as daemons.

Usage: /usr/bin/supervisord [options]

Options:
-c/--configuration FILENAME -- configuration file path (searches if not given)
-n/--nodaemon -- run in the foreground (same as 'nodaemon=true' in config file)
-h/--help -- print this usage message and exit
-v/--version -- print supervisord version number and exit
-u/--user USER -- run supervisord as this user (or numeric uid)
-m/--umask UMASK -- use this umask for daemon subprocess (default is 022)
...

配置

运行这个命令可以生成一个默认的配置文件：

echo_supervisord_conf > /etc/supervisord/supervisord.conf

生成成功后，打开编辑这个文件，把最后的 include 块的注释打开，并修改如下：

[include]
files = /etc/supervisor/*.conf

新增的 Supervisor 配置文件放在 /etc/supervisor 目录下，并且以 conf 结尾。

这时我们使用新的配置文件来启动 Supervisor：

supervisord -c /etc/supervisord.conf

• 如果提示已经有进程在运行，那么先 kill 掉它。

[root@caoxl ~]# supervisord -c /etc/supervisord.conf 
Error: Another program is already listening on a port that one of our HTTP servers is configured to use.  Shut this program down first before starting supervisord.
For help, use /usr/bin/supervisord -h

• 找到旧进程, kill掉

[root@caoxl ~]# ps -ef | grep supervisord
root       551 31716  0 10:53 pts/3    00:00:00 grep --color=auto supervisord
root     32156     1  0 10:18 ?        00:00:00 /usr/bin/python2 /usr/bin/supervisord -c ./supervisor/supervisord.conf
[root@caoxl ~]# kill -9 32156

使用

Supervisor管理LaravelS进程

• 新增 /etc/supervisor/supervisord.conf 配置文件

[program: laravel6]
command=/usr/local/php/php72/bin/php /var/www/laravel6/bin/laravels start -i
directory=/var/www/laravel6
process_name=%(process_num)s
autorestart=true
autostart=true
stderr_logfile=/var/www/laravel6/storage/logs/supervisord-stderr.log
stdout_logfile=/var/www/laravel6/storage/logs/supervisord-stdout.log
user=root
numprocs=1
startsecs=1

• 说明
• command: 运行程序的命令
• directory: 命令执行的目录
• autorestart: 程序意外退出是否自动重启
• autostart: 是否自动启动
• stderr_logfile: 错误日志文件
• stdout_logfile: 输出日志文件
• user: 进程执行的用户身份
• numprocs: 进程数量
• startsecs: 自动重启间隔

一切就绪后，我们使用如下命令就可以启动进程的监听了：

[root@caoxl ~]# sudo supervisorctl reread
laravel6: changed

[root@caoxl ~]# sudo supervisorctl update
laravel6: stopped
laravel6: updated process group

[root@caoxl ~]# sudo supervisorctl start laravel6:*

• 检查开启成功

[root@caoxl ~]# ps -ef | grep laravels
root      2258   593  0 11:15 ?        00:00:00 /var/www/laravel6 laravels: master process
root      2269  2258  0 11:15 ?        00:00:00 /var/www/laravel6 laravels: manager process
root      2275  2269  0 11:15 ?        00:00:00 /var/www/laravel6 laravels: task worker process 4
root      2276  2269  0 11:15 ?        00:00:00 /var/www/laravel6 laravels: task worker process 5
root      2277  2269  0 11:15 ?        00:00:00 /var/www/laravel6 laravels: task worker process 6
root      2278  2269  0 11:15 ?        00:00:00 /var/www/laravel6 laravels: task worker process 7
root      2279  2269  0 11:15 ?        00:00:00 /var/www/laravel6 laravels: worker process 0
root      2280  2269  0 11:15 ?        00:00:00 /var/www/laravel6 laravels: worker process 1
root      2281  2269  0 11:15 ?        00:00:00 /var/www/laravel6 laravels: worker process 2
root      2282  2269  0 11:15 ?        00:00:00 /var/www/laravel6 laravels: worker process 3
root      2337  1412  0 11:16 pts/4    00:00:00 grep --color=auto laravels

• 检查LaravelS进程

[root@caoxl laravel6]# php bin/laravels info
