3、安装libmemcached 

[root@phpdragon home]# tar -zxvf libmemcached-1.0.18.tar.gz
[root@phpdragon home]# cd libmemcached-1.0.18
[root@phpdragon libmemcached-1.0.18]# whereis memcached //获取memcached的安装目录
memcached: /usr/local/bin/memcached

[root@phpdragon home]# ./configure -prefix=/usr/local/libmemcached -with-memcached=/usr/local/bin/memcached
[root@phpdragon libmemcached-1.0.18]# make && make install

[root@phpdragon libmemcached-1.0.18]# whereis libmemcached  //获取libmemcached的安装目录
libmemcached: /usr/local/libmemcached

4、安装php-memcached 

[root@phpdragon home]# tar -zxvf php_memcached-2.2.0.tgz
[root@phpdragon home]# cd memcached-2.2.0/
[root@phpdragon memcached-2.2.0]# phpize  //显示没有安装phpize
