所需软件包
libmemcached-1.0.9 https://launchpad.net/libmemcached/1.0/1.0.9/+download/libmemcached-1.0.9.tar.gz
memcached-2.1.0 http://pecl.php.net/get/memcached-2.1.0.tgz （注意上一版本即memcached-2.0.1.tgz 这个包有bug）
系统升级如下：
CentOS release 5.5
CPU = 64-bit, OS = 64-bit
Compiler GNU CC version 4.1.2 20080704 (Red Hat 4.1.2-48)
注意：之前已经安装了libmemcached-1.0.2及php和php的扩展memcached-1.0.2
一、安装libmemcached-1.0.9
[root@niutian365 packages]# tar zxvf libmemcached-1.0.9.tar.gz
[root@niutian365 packages]# cd libmemcached-1.0.9
[root@niutian365 libmemcached-1.0.9]# ./configure --prefix=/usr/local/libmemcached --with-memcached
升级libmemcached从1.0.2升级到1.0.9编译出错如下提示：

处理如下：
[root@niutian365 libmemcached-1.0.9]# yum install gcc44 gcc44-c++ libstdc++44-devel
[root@niutian365 libmemcached-1.0.9]# export CC=/usr/bin/gcc44
[root@niutian365 libmemcached-1.0.9]# export CXX=/usr/bin/g++44
重新编译安装libmemcached-1.0.9
[root@niutian365 libmemcached-1.0.9]# ./configure --prefix=/usr/local/libmemcached --with-memcached
[root@niutian365 libmemcached-1.0.9]# make
[root@niutian365 libmemcached-1.0.9]# make install
二、升级安装php的memcached扩展memcached-2.1.0
[root@niutian365 packages]# tar zxvf memcached-2.1.0.tgz
[root@niutian365 packages]# cd memcached-2.1.0
[root@niutian365 memcached-2.1.0]# /usr/local/php/bin/phpize
[root@niutian365 memcached-2.1.0]# ./configure --with-php-config=/usr/local/php/bin/php-config --with-libmemcached-dir=/usr/local/libmemcached
[root@niutian365 memcached-2.1.0]# make
[root@niutian365 memcached-2.1.0]# make install
