我正在使用ubuntu Natty和 PHP 5.3.5和 PECL Gearman 0.8.0.这是版本信息：

当我试图通过命令行运行Gearman客户端时,我遇到了分段错误(我已经让我的工作人员运行了).

这是我在命令行上得到的：

root@Local:~/sandBox# PHP PHP_gearman_client.PHP
Sending job
Segmentation fault

这是我的工人代码：

<?PHP

echo "Starting\n";

# Create our worker object.
$gmworker= new GearmanWorker();

# Add default server (localhost).
$gmworker->addServer();

# Register function "reverse" with the server. Change the worker function to
# "reverse_fn_fast" for a faster worker with no output.
$gmworker->adDFunction("reverse","reverse_fn");

PRint "Waiting for job...\n";
while($gmworker->work())
{
  if ($gmworker->returnCode() != GEARMAN_SUCCESS)
  {
    echo "return_code: " . $gmworker->returnCode() . "\n";
    break;
  }
}

function reverse_fn($job)
{
  echo "Received job: " . $job->handle() . "\n";

  $workload = $job->workload();
  $workload_size = $job->workloadSize();

  echo "Workload: $workload ($workload_size)\n";

  # This status loop is not needed,just showing how it works
  for ($x= 0; $x < $workload_size; $x++)
  {
    echo "Sending status: " . ($x + 1) . "/$workload_size complete\n";
    $job->sendstatus($x,$workload_size);
    sleep(1);
  }

  $result= strrev($workload);
  echo "Result: $result\n";

  # Return what we want to send back to the client.
  return $result;
}

# A much simpler and less verbose version of the above function would be:
function reverse_fn_fast($job)
{
  return strrev($job->workload());
}

?>

这是我的客户端代码：

<?PHP

# Create our client object.
$gmclient= new GearmanClient();

# Add default server (localhost).
$gmclient->addServer();

echo "Sending job\n";

# Send reverse job
do
{
  $result = $gmclient->do("reverse","Hello!");

  # Check for VARIoUs return packets and errors.
  switch($gmclient->returnCode())
  {
    case GEARMAN_WORK_DATA:
      echo "Data: $result\n";
      break;
    case GEARMAN_WORK_STATUS:
      list($numerator,$denominator)= $gmclient->DOStatus();
      echo "Status: $numerator/$denominator complete\n";
      break;
    case GEARMAN_WORK_FAIL:
      echo "Failed\n";
      exit;
    case GEARMAN_SUCCESS:
      break;
    default:
      echo "RET: " . $gmclient->returnCode() . "\n";
      exit;
  }
}
while($gmclient->returnCode() != GEARMAN_SUCCESS);

?>

编辑

似乎分段错误是由Imagick引起的.所以我做了以下处理这个问题.

>删除imagick dpkg –purge –force-all PHP5-imagick.我在设置PHP时安装了这个
>重启PHP(这可能会有所不同,具体取决于你安装PHP的方式)
>重启Gearman作业服务器/etc/init.d/gearman-job-server stop&& /etc/init.d/gearman-job-server

现在一切似乎都运转正常.
