php判断进程是否存在

//计划任务定时检测master进程是否存在,不存在则启动,以root用户运行  
public function checkMaster()
  
{
  
$cmd = 'ps axu|grep "UctDataWorker masterRun"|grep -v "grep"|wc -l';
  
$ret = shell_exec("$cmd");
  

  
$ret = rtrim($ret, "\r\n");
  

  
if($ret === "0") {
  
$path = dirname(__FILE__) . '/index.php';
  
$php_path = Config::$php_path;
  
$start_master_cmd = "nohup ".$php_path." ".$path." UctDataWorker masterRun >> /data/log/uctWorker.log 2>&1 &";
  
$ret = shell_exec("$start_master_cmd");
  
}
  
}
