lvs+keepalived配置方法

作用我就不多解释，大家百度查，直接切入正题！

环境：

Centos 5.4

LVS-master: 172.16.17.134

LVS-backup: 172.16.17.135

VIP: 172.16.17.133

web1: 172.16.17.136

web2: 172.16.17.137

在LVS-master和LVS-backup上进行如下：

安装ipvsadm:

先要做一个连接文件： ln -s /usr/src/kernels/2.6.18-308.8.1.el5-i686/ /usr/src/linux/

注意：如果ll /usr/src/kernels/ 目录下没东西，则 yum -y install kernel-devel解决

wget http://www.linuxvirtualserver.org/software/kernel-2.6/ipvsadm-1.24.tar.gz
tar -zxvf ipvsadm-1.24.tar.gz

cd ipvsadm-1.24

make

make install

安装keepalived:

wget http://www.keepalived.org/software/keepalived-1.1.15.tar.gz
tar -zxvf keepalived-1.1.15.tar.gz

cd keepalived-1.1.15

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

make

make install

设置开机启动，添加到服务

cp /usr/local/keepalived/sbin/keepalived /usr/sbin/

cp /usr/local/keepalived/etc/sysconfig/keepalived /etc/sysconfig/

cp /usr/local/keepalived/etc/rc.d/init.d/keeplived /etc/init.d/

mkdir /etc/keepalived

vim /etc/keepalived/keepalived.conf --------------配置文件内容可复制已建好文档

vim /usr/local/keepalived/etc/keepalived/keepalived.conf ---------这个是最初配置文件

后端服务器配置realserver（所有后端都同样配置）：

vim lvs-realserver.sh ------------内容可复制建好文档

chmod 755 lvs-realserver.sh

开启服务：

在LVS-master和LVS-backup上执行： service keepalived start

在web1和web2上执行 /root/lvs-realserver.sh start

停掉master上的keepalived，vip就已经绑定到backup上了

停掉任何一台web都能正常访问
