前言：由于服务器资源有限，keepalived未配主主、只配了一个VIP。本人在香港机房生产环境部署的实际案例，从2013年9月开始运行，服务从未挂过。由于涉及到生产环境，系统展示就不贴出来了。希望大家给予意见！Webserver部署的是lnmp环境，采用我自己写的一键编译安装脚本，安装目录在/data/webserver/。如大家想借鉴我的编译安装脚本，请留言向我索取。
一、架构规划
1、服务器IP地址规划 VIP：192.168.1.6 real_server1:192.168.1.7 real_server2:192.168.1.8 WebServer1:192.168.1.9 WebServer2:192.168.1.10 memcache: 192.168.1.11 mysql主：192.168.1.12 mysql从：192.168.1.2 2、服务器操作系统 所使用的操作系统均为CentOS 6.4 3、网络拓扑图
二、负载服务器配置
1.LVS主服务器配置 安装yum install keepalived ipvsadm
chkconfig keepalived on vim /etc/ keepalived/keepalived.conf 1

四、Memcache服务器部署
1.安装memcached

| yum -y install libevent libevent-devel make gcc gcc-c++ build-essential make
memcached (){
pwd
wget -c http://42.120.20.242/memcached-1.4.15.tar.gz
tar zxvf memcached-1.4.15.tar.gz
cd memcached-1.4.15/
./configure --with-libevent=/usr/local --prefix=/usr/local/memcached
make &&make install
cd ../
|
2.开启memcached实例，本项目中开了两个实例。如下
memcached -d -m 2500 -u root -l 192.168.1.13 -p 11211 -c 20480 -P /tmp/memcached.pid –v memcached -d -m 2500 -u root -l 192.168.1.13 -p 11212 -c 20480 -P /tmp/memcached2.pid –v
