我将 Ubuntu Natty 与 PHP 5.3.5 和 PECL Gearman 0.8.0 一起使用.这是版本信息:

我在尝试通过命令行运行 Gearman 客户端时遇到段错误(我已经让我的 worker 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 worker 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

看来段错误是由 Imagick 引起的。所以我做了以下事情来处理这个问题。

1. 删除 imagick dpkg --purge --force-all php5-imagick。我在设置 PHP 时已经安装了它
2. 重新启动 PHP(这可能会因您安装 php 的方式而异)
3. 重新启动 Gearman 作业服务器 /etc/init.d/gearman-job-server stop &&/etc/init.d/gearman-job-server

现在似乎一切正常。

最佳答案

因为段错误意味着您的安装有问题。运行 dmesg 以查看更多详细信息，某些可能被禁用的 php 扩展可能存在问题。
