multiprocess

  • [readme in english]
  • 基于swoole的脚本管理，用于多进程和守护进程管理；
  • 可轻松让普通脚本变守护进程和多进程执行；
  • 进程个数可配置，可以根据配置一次性执行多条命令；
  • 子进程异常退出时,主进程收到信号，自动拉起重新执行；
  • 支持子进程平滑退出，防止重启服务对业务造成影响；
  • 不限定编程语言，PHP/Python/Java/Golang/C#等脚本都可以管理
  • PHP/python/js等脚本需要跑一个或多个脚本消费队列/计算等任务
  • 实现脚本退出后自动拉起，防止消费队列不工作，影响业务
  • 其实supervisor可以轻松做个事情，这个只是PHP的另一种实现，不需要换技术栈

4. 配置实例

  • 一次性执行多个命令
    'logPath'   => __DIR__ . '/log',
    'exec'      => [
        [
            'name'      => 'kcloze-test-1',
            'bin'       => '/usr/bin/php',
            'binArgs'   => [__DIR__ . '/test/test.php', 'oop', '123'],
            'workNum'   => 3,
        ],
        [
            'name'      => 'kcloze-test-2',
            'bin'       => '/usr/bin/php',
            'binArgs'   => [__DIR__ . '/test/test2.php', 'oop', '456'],
            'workNum'   => 5,
        ],
        [
            'name'      => 'kcloze-test-3',
            'bin'       => '/usr/bin/python',
            'binArgs'   => [__DIR__ . '/test/test3.py', 'oop', '369'],
            'workNum'   => 2,
        ],
    ],

5.1 启动

  • chmod -R u+r log/
  • php multiprocess.php start >> log/system.log 2>&1

5.2 平滑停止服务，根据子进程执行时间等待所有服务停止

  • php multiprocess.php stop

5.3 强制停止服务[慎用]

  • php multiprocess.php exit

5.4 强制重启

  • php multiprocess.php restart >> log/system.log 2>&1

5.5 监控

  • ps -ef|grep 'multi-process'

5.6 启动参数说明

6. 服务管理

启动和关闭服务,有两种方式:

6.1 php脚本(主进程挂了之后,需要手动启动)

./multiprocess.php start|stop|exit|restart

6.2 使用systemd管理(故障重启、开机自启动)

更多systemd介绍

1. 根据自己项目路径,修改 systemd/multiprocess.service
2. sudo cp -f systemd/multiprocess.service /etc/systemd/system/
3. sudo systemctl --system daemon-reload
4. 服务管理
#启动服务
sudo systemctl start multiprocess.service
#reload服务
sudo systemctl reload multiprocess.service
#关闭服务
sudo systemctl stop multiprocess.service
