1、安裝keepalived。
tar xvf keepalived-1.2.7.tar.gz cd keepalived-1.2.7 ./configure --prefix=/usr/local/keepalived ##可能會提示安裝popt-devel包，yum即可 make && make install
2、整理配置文件與腳本
mkdir /etc/keepalived ##keepalived默認配置文件從/etc/keepalived下讀取 cp /usr/local/keepalived/sbin/keepalived /usr/sbin/ ##就一個二進制文件，直接拷貝過去即可，多的話就更改PATH吧 cp /usr/local/keepalived/etc/sysconfig/keepalived /etc/sysconfig/ ##腳本的額外配置文件讀取位置 cp /usr/local/keepalived/etc/rc.d/init.d/keepalived /etc/init.d/ ##啓動腳本你懂得 cp /usr/local/keepalived/etc/keepalived/keepalived.conf /etc/keepalived/ ##我們關鍵的keepalived配置文件
3、修改server1的/etc/keepalived/keepalived.conf
! Configuration File for keepalived
global_defs {
notification_email {
[email protected] ##出故障發送郵件給誰
}
notification_email_from keepalived@localhost ##故障用哪個郵箱發送郵件
smtp_server 127.0.0.1 ##SMTP_Server IP
smtp_connect_timeout 30 ##超時時間
router_id LVS_DEVEL ##服務器標識
}
vrrp_instance VI_1 {
state BACKUP
##狀態，都爲BACKUP，它們會推選Master，如果你寫MASTER，它就會是Master，
##當Master故障時Backup會成爲Master,當原來的Master恢復後，原來的Master會成爲Master
interface eth0 ##發送VRRP的接口，仔細看你的是不是eth0
virtual_router_id 51 ##虛擬路由標識，同一個組應該用一個，即Master與Backup同一個
priority 100 ##重要的優先級哦
nopreempt ##不搶佔，一個故障時，重啓後恢復後不搶佔意資源
advert_int 1 ##同步間隔時長
authentication { ##認證
auth_type PASS ##認證方式
auth_pass www.laoguang.me ##密鑰
}
virtual_ipaddress {
192.168.1.18 ##VIP
}
}
##後面的刪除吧，LVS上纔有用拷貝到server2上一份，只修改priority 90 即可
