一、memcached服务端的安装
1.安装前需要先安装libevent:
下载地址：
http://www.monkey.org/~provos/libevent/
安装 libevent-1.4.13-stable.tar.gz
#默认安装在/usr/local/lib/
2. memcached安装:
下载地址：
http://memcached.org/
安装 memcached-1.4.5.tar.gz
#默认安装在/usr/local/bin/
3.测试时候发现会出现以下错误信息：
/usr/local/memcached/bin/memcached: error while loading shared libraries: libevent-1.4.so.2: cannot open shared object file: No such file or directory
错误的原因是未在系统中注册Libevent. 解决方法如下:
vi /etc/ld.so.conf.d/libevent-i386.conf
输入：
/usr/local/lib/
最后不要忘了
ldconfig
4.CentOS Memcached运行
/web/memcached/bin/memcached -m 512 -u nobody -vv
会看到如下信息：

memcached运行正常。
二、memcached的基本设置：
1、启动Memcached的服务器端：
/web/memcached/bin/memcached -d -m 64 -u nobody -l 127.0.0.1 -p 11211 -c 1024 -P /tmp/memcached.pid
-d选项是启动一个守护进程，
-m是分配给Memcache使用的内存数量，单位是MB
-u是运行Memcache的用户
-l是监听的服务器IP地址，IP地址127.0.0.1
-p是设置Memcache监听的端口，默认为11211
-c选项是最大运行的并发连接数，默认是1024
-P是设置保存Memcache的pid文件，/tmp/memcached.pid，这个选项加不加无所谓
2、如果要结束memcached进程，执行：
kill `cat /tmp/memcached.pid`
或者
killall -9 /web/memcached/bin/memcached
也可以启动多个守护进程，不过端口不能重复。
3、重启apache，service httpd restart
memcached环境测试：
运行下面的php文件，如果有输出This is a test!，就表示环境搭建成功。
$mem = new Memcache;
$mem->connect("127.0.0.1",11211);
$mem->set('key', "This is tell you: memcached rum success!", 0, 60);
$val = $mem->get('key');
echo $val;
?>
三、安装memcached的PHP扩展
1、在http://pecl.php.net/package/memcache 选择相应想要下载的memcache版本。
2、安装PHP的memcache扩展
tar vxzf memcache-2.2.5.tgz
我的php安装在/web/php
确保编译参数为以下：
/web/php/bin/phpize
./configure --with-php-config=/web/php/bin/php-config
3、安装完后会有类似这样的提示：
Installing shared extensions: /web/php/lib/php/extensions/no-debug-zts-20060613/
4、把php.ini中的extension_dir = "./"修改为
extension_dir = "/web/php/lib/php/extensions/no-debug-zts-20060613/"
5、添加一行来载入memcache扩展：extension=memcache.so
1.安装前需要先安装libevent:
下载地址：
http://www.monkey.org/~provos/libevent/
安装 libevent-1.4.13-stable.tar.gz
#默认安装在/usr/local/lib/
