php实现 master

具体代码如下所示：

<?phpclass worker{  public static $count = 2;  public static function runall(){    static::runmaster();    static::moniprocess();  }  //开启主进程  public static function runmaster(){    //确保进程有最大操作权限    unmask(0);    $pid = pcntl_fork();her什么意思    if($pid 名著小说推荐> 0){      echo "主进程进程 $pid \n";      exit;      }el if($pid == 0){      if(-1 === posix_tsid()){          throw new exception("tsid fail");      }      for ($i=0; $i < s快乐作文网elf::$count; $i++) {        static::runworker();      }      @cli_t_process_title("master_process");    }el{      throw new exception("创建主进程失败");    }  }   //开启子进程  public static function runworker(){    unmask(0);    $pid = pcntl_fork();    if($pid > 0){      // echo "创建子进程 $pid \n";    }el if($pid == 0){      if(-1 === posix_tsid()){        throw new exception("tsid fail");      }      @cli_t_process_title("worker_process");      while(1){        sleep(1);      }    }el{      throw new exception("创建子进程失败");    }  }  //监控worker进程  public function moniprocess(){    while( $pid = pcntl_wait($status)){      if($pid == -1){        break;      }el{        static::runworker();      }    }  }}worker::runall();

ps -auxur    pid %cpu %mem  vsz  rss tty   stat start  time commandroot     1 0.0 0.0 18200 3076 pts/0  ss+ 14:05  0:00 bashroot     6 0.0 0.0 18208 3252 pts/1  ss  14:06  0:00 bashroot    19 0.0 0.0 18204 3248 pts/2  ss+ 14:11  0:00 bashroot    64 0.0 0.2 348488 8320 ?    ss  15:32  0:00 master_processroot    65 0.0 0.2 348488 8400 ?    ss  15:32  0:00 worker_processroo绵阳职业技术学校t    66 0.0 0.2 348488 8400 ?    ss  15:32  0:00 worker_processroot    67 0.0 0.0 36640 2804 pts/1  r+  15:32  0:00 ps -aux

执行命令 kill 65，杀死进程 65 则master_process 进程会再自动开启一个子进程

ur    pid %cpu %mem  vsz  rss tty   stat start  time commandroot     1 0.0 0.0 18200 3076 pts/0  ss+ 14:05  0:00 bashroot     6 0.0 0.0 18208 3252 pts/1  ss  14:06  0:00 bashroot    19 0.0 0.0 18204 3248 pts/2  ss+ 14:11  0:00 bashroot    64 0.0 0.2 348488 8320 ?    ss  15:32  0:00 master_processroot    66 0.0 0.2 348488 8400 ?    ss  15:32  0:00 worker_processroot    68 0.0 0.1 348488 5796 ?    ss  15:34  0:00 worker_processroot    69 0.0 0.0 36640 2728 pts/1  r+  15:34  0:00 ps 尖的组词-aux
