Memcached使用与实践

1. ubuntu下：sudo apt-get update,sudo apt-get install mysql-server php5-mysql php5 memcached php5-memcached php5-memcache
2. 或者centos:yum update yum install memcached 开启服务:systemctl restart memcached,systemctl enable memcached,查看服务状态：systemctl status memcached
3. 简单使用：
   $mem = new Memcache();
   $mem->connect('localhost',11211); //default port is 11211
   $mem->set('key','value',$timeout);
   $mem->get('key');
