大家好,又见面了,我是全栈君。
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。
安装环境
代码语言:javascript复制应该保证系统中安装了如下软件
gcc-4.4
make
autoconf
PECL安装
代码语言:javascript复制pecl install swoole
php.ini 配置
代码语言:javascript复制extension=swoole.so
查看是否安装成功
代码语言:javascript复制php -m | grep swoole
> swoole
swoole升级
查看当前版本
代码语言:javascript复制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
代码语言:javascript复制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
代码语言:javascript复制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
代码语言:javascript复制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
代码语言:javascript复制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");
}
});
代码语言:javascript复制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
