一、更改配置yum源

??? 1.備份：mv

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

??? 2.下載阿里源：wget -O

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

??? 3.緩存：yum makecache

二、安裝lrzsz

??? 1.yum -y install lrzsz

三、安裝keepalived

1.yum -y install keepalived

2.創(chuàng)建目錄

??mkdir /data/UnicomSMS/Keepalived

? mkdir /data/UnicomSMS/Keepalived/lock

? mkdir /data/UnicomSMS/Keepalived/lock/subsys

四、修改配置文件

Master

[if !vml]

[endif]

Slave

[if !vml]

[endif]

Nginx檢查腳本

[if !vml]

[endif]

五、啟動測試

/etc/init.d/keepalived

start

[if !vml]

[endif]

六、VIP漂移測試

正常情況

[if !vml]

[endif]

停到主上的keepalived vip地址會飄向備

[if !vml]

[endif]

在把主上的keepalived啟動vip會搶占到主

[if !vml]

[endif]

七、方便管理

1.ln -s /var/lock/subsys/keepalived /data/UnicomSMS/Keepalived/lock/subsys/

2.ln -s /etc/keepalived/keepalived.conf /data/UnicomSMS/Keepalived/

3.ln -s /etc/keepalived/nginx_check.sh/data/UnicomSMS/Keepalived/
