最近搭建keepalived双机热备, 在网上博采众之所长, 整理一下自己的笔记!

在新搭建的centos6.x下最好下载一下阿里云源:

　　centos：http://mirrors.aliyun.com/help/centos

1、备份

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

2、下载新的CentOS-Base.repo 到/etc/yum.repos.d/

CentOS 5

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-5.repo

或者

curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-5.repo

CentOS 6

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo

或者

curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo

CentOS 7

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

或者

curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

3、之后运行yum makecache生成缓存

　　准备2台电脑来做这个实验:

　　192.168.232.137        web服务器　　keepalived nginx
　　192.168.232.138        web服务器　　keepalived nginx\

　　虚拟IP (VIP)：192.168.232.17

　　虚拟IP (VIP)：192.168.232.18

137上面:

　　vim /etc/sysconfig/network-scripts/ifcfg-eth0

keepalive+双机热备+nginx
