14.12.22更新：
此方法词库太大时效率很差，可以将词库以key->vale方式加载到内存，文章分词遍历再替换。

使用yum直接安装：

yum install gearmand

安装PHP扩展：

yum install libgearman re2c
wget http://pecl.php.net/get/gearman-1.1.2.tgz
tar zxvf gearman-1.1.2.tgz 
cd gearman-1.1.2
phpize 
./configure 
make && make install
echo "extension=gearman.so" >> /etc/php.ini

启动任务分发进程：

gearmand -d --keepalive --libtokyocabinet-file /tmp/gearmand.tch

PHP客户端，提交任务：

<?php  
   $client= new GearmanClient();  
   $client->addServer("127.0.0.1", 4730); 
   //发送任务到Job，处理函数和数据
   //echo $client->do("reverse", "Hello World!");  
   echo $client->doBackground("reverse", "Hello World!");  
?> 

PHP执行端：

<?php  
   $worker= new GearmanWorker();  
   $worker->addServer("127.0.0.1", 4730); 
   //处理接收到数据的回调函数
   $worker->addFunction("reverse", "reverse_function");  
   while ($worker->work());  
   function reverse_function($job)  
   {  
      for($i = 0; $i < 10; $i++){  
         sleep(1);  
         echo "{$i}\n";  
      }  
      return $job->workload();  
   }  
?>
