PHP监测Memcache服务端的运行状况

PHP监测Memcache服务端的运行状况

代码如下,代码为memcache官方代码,引用在此,做一下简单的说明:

1、设置用户名和密码

define(‘ADMIN_USERNAME’,’admin’); // Admin Username
define(‘ADMIN_PASSWORD’,’123456′);  // Admin Password

2、配置服务器及其端口,可以配置多台

$MEMCACHE_SERVERS[] = ‘localhost:11211’; // add more as an array
$MEMCACHE_SERVERS[] = ‘localhost:11212’; // add more as an array
