memcache在php中编译
#  wget http://mylinux.5d6d.com/userdirs/c/f/mylinux/memcache-2.2.3.tgz
# tar zxvf memcache-2.2.3.tgz
# cd memcache-2.2.3
# /usr/local/php/bin/phpize
# ./configure --with-php-config=/usr/local/php/bin/php-config
# make
# make install
# cp modules/memcache.so /usr/local/php/ext/
然后在php.ini 中添加
extension = memcache.so
修改扩展路径为：extension_dir = "/usr/local/php/ext"
保存后可以利用 /usr/local/php/bin/php-cgi -m  检测和查看具体的参数
