PHP 连接 Memcached 需要先安装 memcache 扩展模块：

cd /usr/local/srcwget http://www.apelearn.com/bbs/data/attachment/forum/memcache-2.2.3.tgztar xf memcache-2.2.3.tgzcd memcache-2.2.3/usr/local/php/bin/phpize./configure --with-php-config=/usr/local/php/bin/php-configmake && make installecho ‘extension = "memcache.so"‘ >> /usr/local/php/etc/php.ini

[root@localhost ~]# /usr/local/php/bin/php -m | grep memcachememcache

测试 PHP 是否连接 Memcached：

[root@localhost ~]# curl http://www.apelearn.com/study_v2/.memcache.txt > 1.php

[root@localhost ~]# /usr/local/php/bin/php 1.php //看到如下输出则表示连接成功Get key1 value: This is first value<br>Get key1 value: This is replace value<br>Get key2 value: Array( [0] => aaa [1] => bbb [2] => ccc [3] => ddd)
