swoole是事件驱动的,server.php一直监听端口,当客户端有数据流过去,则进行监听读取,并进处理。本文将分享给大家swoole教程之进程操作!
安装环境
应该保证系统中安装了如下软件
gcc-4.4+ make autoconf
PECL安装
pecl install swoole
php.ini 配置
extension=swoole.so
查看是否安装成功
php -m | grep swoole > swoole
swoole升级
查看当前版本
php --ri swoole | grep Version #结果 > Version => 1.9.6
pecl升级
pecl upgrade swoole
swoole进程初识
swoole 默认是多进程模式
Master进程 / Manager进程 / Worker进程 / Task进程
server实例代码
server-process.php
$serv = new swoole_server('127.0.0.1', 9501); $serv->set([ 'worker_num' => 2, 'task_worker_num' => 1, ]); $serv->on('Connect', function ($serv, $fd) { }); $serv->on('Receive', function ($serv, $fd, $fromId, $data) { }); $serv->on('Close', function ($serv, $fd) { }); $serv->on('Task', function ($serv, $taskId, $fromId, $data) { }); $serv->on('Finish', function ($serv, $taskId, $data) { }); $serv->start();
对实例代码 进行pstree进程关系
pstree的结果有5个进程,因为swoole的进程模型是(Master-Manager-Worker),5个进程 = master进程(1个) + manager进程(1个) + worker_num(2个) + task_worker_num(1个)
$ pstree | grep server-process | | \-+= 02548 php server-process.php | | \-+- 02549 php server-process.php | | |--- 02550 php server-process.php | | |--- 02551 php server-process.php | | \--- 02552 php server-process.php | \--- 02572 grep server-process
从结果可以看出:
02548 是Master进程,它处于“root”层级
02549 是Manager进程
Worker进程和Task进程就是 02550、02551和02552
设置进程名称备注,再进行pstree进程关系
Master进程:
启动:onStart
关闭:onShutdown
Manager进程:
启动:onManagerStart
关闭:onManagerStop
Worker进程:
启动:onWorkerStart
关闭:onWorkerStop
mac下不支持swoole_set_process_name函数,可以用centos进行测试
$serv->on("start", function ($serv){ swoole_set_process_name('server-process: master'); }); // 以下回调发生在Manager进程 $serv->on('ManagerStart', function ($serv){ swoole_set_process_name('server-process: manager'); }); $serv->on('WorkerStart', function ($serv, $workerId){ if($workerId < $serv->setting['worker_num']) { // $workerId = 0~worker_num之间,则为worker进程 swoole_set_process_name("server-process: worker"); } else { // $workerId >= worker_num之间,则为task进程 swoole_set_process_name("server-process: task"); } });
ps出来的结果
# ps aux | grep server-process root 27546 xxx... server-process: master root 27547 xxx... server-process: manager root 27549 xxx... server-process: task worker root 27550 xxx... server-process: worker root 27551 xxx... server-process: worker root 27570 xxx... grep --color=auto simple
