1、安装keepalived。
tar xvf keepalived-1.2.7.tar.gz cd keepalived-1.2.7 ./configure --prefix=/usr/local/keepalived ##可能会提示安装popt-devel包，yum即可 make && make install
2、整理配置文件与脚本
mkdir /etc/keepalived ##keepalived默认配置文件从/etc/keepalived下读取 cp /usr/local/keepalived/sbin/keepalived /usr/sbin/ ##就一个二进制文件，直接拷贝过去即可，多的话就更改PATH吧 cp /usr/local/keepalived/etc/sysconfig/keepalived /etc/sysconfig/ ##脚本的额外配置文件读取位置 cp /usr/local/keepalived/etc/rc.d/init.d/keepalived /etc/init.d/ ##启动脚本你懂得 cp /usr/local/keepalived/etc/keepalived/keepalived.conf /etc/keepalived/ ##我们关键的keepalived配置文件
3、修改server1的/etc/keepalived/keepalived.conf
! Configuration File for keepalived
global_defs {
notification_email {
[email protected] ##出故障发送邮件给谁
}
notification_email_from keepalived@localhost ##故障用哪个邮箱发送邮件
smtp_server 127.0.0.1 ##SMTP_Server IP
smtp_connect_timeout 30 ##超时时间
router_id LVS_DEVEL ##服务器标识
}
vrrp_instance VI_1 {
state BACKUP
##状态，都为BACKUP，它们会推选Master，如果你写MASTER，它就会是Master，
##当Master故障时Backup会成为Master,当原来的Master恢复后，原来的Master会成为Master
interface eth0 ##发送VRRP的接口，仔细看你的是不是eth0
virtual_router_id 51 ##虚拟路由标识，同一个组应该用一个，即Master与Backup同一个
priority 100 ##重要的优先级哦
nopreempt ##不抢占，一个故障时，重启后恢复后不抢占意资源
advert_int 1 ##同步间隔时长
authentication { ##认证
auth_type PASS ##认证方式
auth_pass www.laoguang.me ##密钥
}
virtual_ipaddress {
192.168.1.18 ##VIP
}
}
##后面的删除吧，LVS上才有用拷贝到server2上一份，只修改priority 90 即可
