windows 64bit 环境下安装
下载 memcache 安装包 ：http://pan.baidu.com/s/1pLcjTzl
解压到d盘任意位置 , cmd(以管理员身份运行，否则安装失败) 执行命令
没有报错说明我们已经安装成功
下载 php_memcache.dll : https://pecl.php.net/package/memcache/3.0.8/windows
我的是5.6的版本 所以下载 64位 TS版本
将dll扩展放入php扩展文件夹中
在php.ini 中添加 extension=php_memcache.dll
然后重启wampserver
注意：apache文件夹中的php.ini 是用于浏览器访问 php文件夹中的php.ini 是适用于命令行运行php脚本
php测试代码 (我的是命令行测试)
linux 安装 （centos 64bit）
安装环境说明：
操作系统：Centos 6.5 -64bit
安装路径：/usr/local/memcached
安装编译需要的扩展包
yum install libevent libevent-devel
下载memcached tgz包 到home文件夹
[root@localhost home]# wget http://memcached.org/files/memcached-1.4.25.tar.gz
解压并编译memcached
tar zxvf memcached-1.4.25.tar.gz
-
打开文件夹 指定安装路径 并编译
cd memcached-1.4.25
./configure --prefix=/usr/local/memcached
make && make install

[root@localhost home]# ./configure --prefix=/usr/local/libevent/
[root@localhost libevent-2.0.21-stable]# make && make install -
重新编译安装memcached服务，并配置libevent
[root@localhost home]# cd memcached-1.4.25
[root@localhost memcached-1.4.25]# ./configure --prefix=/usr/local/memcache/ --with-libevent=/usr/local/libevent/
[root@localhost memcached-1.4.25]# make && make install -
下载 libmemcached tgz包 并编译安装
安装SASL相关环境 yum install cyrus-sasl-plain cyrus-sasl cyrus-sasl-devel cyrus-sasl-lib 官网：http://libmemcached.org/libMemcached.html [root@localhost home]# wget https://launchpadlibrarian.net/165454254/libmemcached-1.0.18.tar.gz [root@localhost home]# tar zxf libmemcached-1.0.18.tar.gz [root@localhost home]# cd libmemcached-1.0.18 [root@localhost libmemcached-1.0.18]# ./configure --prefix=/usr/local/libmemcached --with-memcached --enable-sasl [root@localhost libmemcached-1.0.18] make [root@localhost libmemcached-1.0.18] make install -
下载php memcached 扩展 tgz包
[root@localhost home]# wget https://pecl.php.net/get/memcached-2.2.0.tgz
[root@localhost home]# tar zxf memcached-2.2.0.tgz
[root@localhost home]# cd memcached-2.2.0

./configure --with-php-config=/usr/local/php/bin/php-config
--with-libmemcached-dir=/usr/local/libmemcached --enable-memcached-sasl（注意这个参数）
如果提示下面错误信息 说明我们要安装 libsasl2-dev 
yum直接搜索是没有对应的package的 我们用笨方法
[root@localhost home]# yum search sasl | grep dev
[root@localhost home]# yum install cyrus-sasl-devel

继续编译
./configure --with-php-config=/usr/local/php/bin/php-config --with-libmemcached-dir=/usr/local/libmemcached --enable-memcached-sasl（注意这个参数） make make install# 安装成功后会输出这个地址，这是php扩展模块文件夹
