install memcache for php

本想說這東西就yum一下就好了...
沒想到重裝時，還真卡住了，想不起來怎麼裝的
還是乖乖寫筆記吧

• 架memcache server
  
  1. 事前準備
     yum install libevent
     yum install libmemcached libmemcached-devel
  2. 裝memcache server
     yum install memcached
  3. Start Memcached server
     memcached -d -m 512 -l 127.0.0.1 -p 11211 -u nobody
     d = daemon, m = memory, u = user, l = IP to listen to, p = port)
     
• php存取memcache
  1. 事前準備
     利用pecl安裝，如果沒有的...
     yum install php-pear
  2. 安裝memcache
     pecl install memcache
  3. 設定php.ini
     將extension寫入php.ini
     extension=memcache.so
  4. 設定memcache server位置
     

     $memcache = new Memcache; 
     $memcache->connect('127.0.0.1', 11211) or die ("Could not connect"); //connect to memcached server   
     $mydata = "i want to cache this line"; //your cacheble data   
     $memcache->set('key', $mydata, false, 100); //add it to memcached server   $get_result = $memcache->get('key'); //retrieve your data   
     var_dump($get_result); //show it

就這麼簡單...
