CentOS环境PHP下安装memcache扩展

 
 1、安装libmemcached库 

 
    yum install libmemcached 

 
 2、下载并解压memcache文件 

 
   wget http://pecl.PHP.net/get/memcache-3.0.8.tgz  

 
   tar xzvf memcache-3.0.8.tgz  

 
   cd memcache-3.0.8 

 
 3、执行PHPize扩展安装程序，假设PHPzie的路径为/usr/local/PHP/bin/PHPize,具体的路径得根据自己的环境修改。 

 
 [root@naginx memcache-3.0.8]# /usr/local/PHP/bin/PHPize 

 
 Configuring for: 

 
 PHP Api Version:     20100412 

 
 Zend Module Api No:   20100525 

 
 Zend Extension Api No:  220100525 

 
 4、开始安装扩展memcache 

 
 [root@naginx memcache-3.0.8]# ./configure --enable-memcache \ 

 
  --with-PHP-config=/usr/local/PHP/bin/PHP-config --with-zlib-dir \ 

 
 make && make install  

 
 安装完成后，提示 

 
 Build complete. 

 
 Don't forget to run 'make test'. 

 
 Installing shared extensions:   /usr/local/PHP/lib/PHP/extensions/no-debug-non-zts-20100525/ 

 
 5、最后修改PHP.ini文件，在zend之前加入如下代码。 

 
 vim /usr/local/PHP/lib/PHP.ini 

 
 extension=/usr/local/PHP/lib/PHP/extensions/no-debug-non-zts-20100525/memcache.so 

 
 6、重新启动PHP-fpm 

 
 kill -QUIT pid 

 
 /etc/rc.d/init.d/PHP-fpm restart 

 
 7、通过PHPinfo（）可以查看memcached信息 

 
 8、启动memecached 

 
  
 ./memcached -d -m 100 -l 192.168.1.120 -p 11211 -u root 

 
 9、测试 

 
 附PHP的memcache测试代码： 

 
 <?PHP 

 
 $mem = new Memcache; 

 
 $mem->connect("192.168.1.120",11211) or die("Could not connect"); 

 
 $version = $mem->getVersion(); 

 
 echo "Server's version: ".$version."<br/>\n"; 

 
 $mem->set('hellokey','Hello World',600) or die("Failed to save data at the memcached server"); 

 
 echo "Store data in the cache (data will expire in 600 seconds)<br/>\n"; 

 
 $get_result = $mem->get('hellokey'); 

 
 echo "$get_result is from memcached server.";     

?>

 
 查看命中结果 

 
 telnet 192.168.1.120 11211 

 
 输入命令：status
