【多进程】php实现 master

<?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);        $pid = pcntl_fork();        if($pid &g创业经验t; 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; $i < lf::$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();

执行命令 kill 65，杀死进程 65 则master_pro化学实验室工作总结cess 进程会再自动开启一个子进程
