memcached是一款缓存软件，他是基于C/S模式架构的软件

首先需要搭建好LAMP,LNMP环境

服务端需要安装memcached守护进程，客户端则需要启用memcache进程

服务端安装的软件：

tar -zxvf libevent-1.4.13-stable.tar.gz 

cd libevent-1.4.13-stable

./configure --prefix=/usr/local/libevent

make

make install

cd ..

tar -zxvf memcached-1.4.13.tar.gz 

cd memcached-1.4.13

./configure --prefix=/usr/local/memcached

./configure --prefix=/usr/local/memcached --with-libevent=/usr/local/libevent/

echo $?

make

make install

echo "/usr/local/lib" >>/etc/ld.so.conf

ldconfig

which memcached

/usr/local/memcached/bin/memcached -p 11211 -u root -m 16m -c 10240 -d

lsof -i :11211

pkill memcached

lsof -i :11211

/usr/local/memcached/bin/memcached -p 11211 -u root -m 16m -c 10240 -d

lsof -i :11211

iptables -L




客户端安装的软件：

tar -zxvf libevent-1.4.13-stable.tar.gz 

cd libevent-1.4.13-stable

./configure --prefix=/usr/local/libevent

make && make install

cd ..

tar -zxvf memcache-2.2.5.tgz 

cd memcache-2.2.5

/application/php/bin/phpize 

./configure --enable-memcache --with-php-config=/application/php/bin/php-config --with-zlib-dir

make 

make install

ll  /application/php5.3.27/lib/php/extensions/no-debug-non-zts-20090626/

vim /application/php/etc/php.ini 

killall php-fpm

killall nginx

/application/nginx/sbin/nginx 

/application/php/sbin/php-fpm 

cd /application/nginx/html/

vim index.php

vim ../conf/nginx.conf

/application/nginx/sbin/nginx -s reload

cd /application/php/etc/

mv php.ini /application/php/lib/

cd /application/php/lib/

vim php.ini         客户端需要更改的四个配置

####session.save_handler = memcached

####session.save_path = "tcp://172.16.1.219:11211"

####extension_dir = "/application/php5.3.27/lib/php/extensions/no-debug-non-zts-20090626/"

####extension = memcache.so

killall php-fpm

/application/php/sbin/php-fpm 

/application/nginx/sbin/nginx -t

/application/nginx/sbin/nginx -s reload
