[root@localhost home]# tar -zxvf keepalived-1.1.19.tar.gz
[root@localhost home]# cd keepalived-1.1.19
[root@localhost keepalived-1.1.19]# ./configure --prefix=/usr/local/keepalived
[root@localhost keepalived-1.1.19]# make && make install
[root@localhostkeepalived-1.1.19] cp/usr/local/keepalived/etc/rc.d/init.d/keepalived etc/rc.d/init.d/
[root@localhostkeepalived-1.1.19]# cp /usr/local/keepalived/etc/sysconfig/keepalived /etc/sysconfig/
[root@localhost keepalived-1.1.19]# mkdir /etc/keepalived
[root@localhostkeepalived-1.1.19]#cp /usr/local/keepalived/etc/keepalived/keepalived.conf /etc/keepalived/
[root@localhost keepalived-1.1.19]# cp /usr/local/keepalived/sbin/keepalived /usr/sbin/
1、修改MASTER配置文件
[root@localhost keepalived-1.1.19]# vi /etc/keepalived/keepalived.conf
vrrp_instance VI_1 {
state MASTER
interface eth0
virtual_router_id 51
priority 100

authentication {
auth_type PASS
auth_pass 1111
}
virtual_ipaddress {
192.168.1.20
}
}
virtual_server 192.168.1.20 80 {
delay_loop 6
lb_algo rr
lb_kind NAT

}
real_server 192.168.1.4 80 {

}
connect_timeout 3

}
}
}
2、修改BACKUP配置文件
vrrp_instance VI_1 {
state BACKUP
interface eth0
virtual_router_id 51
priority 50
advert_int 1
authentication {
auth_type PASS
auth_pass 1111
}
virtual_ipaddress {

}
}
virtual_server 192.168.1.20 80 {
delay_loop 6
lb_algo rr
lb_kind NAT
nat_mask 255.255.255.0
persistence_timeout 50
protocol TCP
real_server 192.168.1.3 80 {

}
url {

digest 9b3a0c85a887a256d6939da88aabd8cd
}
connect_timeout 3
nb_get_retry 3
delay_before_retry 3
}
}
}
real_server 192.168.1.4 80 {
weight 1
HTTP_GET {
url {
path /testurl/test.jsp
digest 640205b7b0fc66c1ea91c463fac6334d
