GearmanWorker失敗，'失敗，設置異常選項'

我試圖建立一個使用德語的分佈式處理環境，但我在第一步失敗。我的設置： PHP 5.6.4-1~dotdeb.1 gearman support => enabled libgearman version => 1.1.12 gearman-server-0.6.2.jar GearmanWorker失敗，'失敗，設置異常選項'

樣品工人

<?php 
$worker= new GearmanWorker(); 
echo "worker options: " . $worker->options() . PHP_EOL; 
$worker->setOptions(1); 
echo "worker options: " . $worker->options() . PHP_EOL; 
$worker->addServer("192.168.130.16"); 
$worker->addFunction("reverse", "my_reverse_function"); 
while ($worker->work()); 

function my_reverse_function($job) 
{ 
    return strrev($job->workload()); 
} 
?>

嘗試運行的工作人員出現錯誤時：

[email protected]:~$ php worker.php 
PHP Fatal error: Uncaught exception 'GearmanException' with message 'Failed to set exception option' in /home/vagrant/worker.php:3 
Stack trace:

以下是有關該問題的舊版[bug]（https://bugs.launchpad.net/gearmand/+bug/1043324）報告。使用Java版Gearman服務器的任何特定原因？什麼是Gearman PECL擴展版本使用？ – 2015-02-08 10:25:57

Gearman PECL => gearman 1.1.2穩定。就服務器而言，我想使用java版本，因爲它只需要JVM，所以我可以很容易地在不同的機器上測試它。 – 2015-02-08 21:52:29

原來，這是服務器中的一個錯誤。在提交bug report後，John修復了服務器。版本0.8.10-SNAPSHOT
解決了這個問題，並且像魅力一樣工作。
