## 进程详解 ##

进程就是正在运行程序的一个实例

## 开启进程 ##

### Process.php ###

<?php
    
    $process = new Swoole\Process('callback_function', true);
    
    $pid = $process->start();
    
    function callback_function(Swoole\Process $worker)
    {
        
        $worker->exec('/www/server/php/71/bin/php', array(__DIR__.'/../http_server.php'));
    }
    echo $pid.PHP_EOL;
    Swoole\Process::wait();

### http\_server.php ###

<?php
    
    $http=new swoole_http_server("0.0.0.0",8812);
    
    $http->set(
      [
        'enable_static_handler'=>true,
        'document_root'=>"/www/wwwroot/test.cc",
      ]
    );
    
    //绑定request请求
    $http->on('request',function($request,$response){
        
      //print_r($request->get);
      //$response->end("<h1>HTTPserver</h1>");
      $response->cookie("willem","chenweiguang",time()+1800);
      $response->end("sss".json_encode($request->get));
    });
    
    $http->start();

### 跟踪查看父进程 ###

[root@bogon swoole]# ps aux | grep Process.php 
    root      4948  0.1  0.3 254648 15344 pts/1    S+   18:04   0:00 php Process.php
    root      4975  0.0  0.0 112812   984 pts/0    S+   18:04   0:00 grep --color=auto Process.php
    
    [root@bogon swoole]# pstree -p 4948
    php(4948)───php(4949)─┬─php(4950)─┬─php(4953)
                          │           └─php(4954)
                          ├─{php}(4951)
                          └─{php}(4952)

### 查看开启的子进程 ###

linux网络状态，一般会用netstat -anp命令查看

### 树形目录查看进程master，work进程分析 ###

[root@bogon test.cc]# ps aft | grep http_server.php 
     4949 pts/1    Sl+    0:00      \_ /www/server/php/71/bin/php /www/wwwroot/test.cc/swoole/../http_server.php

     4953 pts/1    S+     0:00              \_ /www/server/php/71/bin/php /www/wwwroot/test.cc/swoole/../http_server.php

     5715 pts/0    S+     0:00  \_ grep --color=auto http_server.php
    [root@bogon test.cc]#

### exec执行服务端 ###

Process.php

<?php
    
    $process = new Swoole\Process('callback_function', true);
    
    $pid = $process->start();
    
    function callback_function(Swoole\Process $worker)
    {
        
        $worker->exec('/www/server/php/71/bin/php', array(__DIR__.'/redis.php'));
    }
    echo $pid.PHP_EOL;
    Swoole\Process::wait();

[root@bogon swoole]# php Process.php 
    4293

redis.php

<?php
    use Swoole\Coroutine\Redis;
    use function Swoole\Coroutine\run;
    
    run(function () {
        
        $redis = new Redis();
        $redis->connect('127.0.0.1', 6379);
        $redis->auth('123456');
        $val = $redis->set('name','process');
    
        print_r($val);
    });
