Keepalived 主备
一、双机主备
global_defs {
router_id keep_171
}
vrrp_instance VI_1 {
# 主用机设置为 MASTER
state MASTER
interface ens33
virtual_rhouter_id 51
priority 100
advert_int 2
authentication {
auth_type PASS
auth_pass 1111
}
virtual_ipaddress {
# 注意:主备两台的vip都是一样的,绑定到同一个vip
192.168.1.161
}
}
global_defs {
router_id keep_172
}
vrrp_instance VI_1 {
# 备用机设置为BACKUP
state BACKUP
interface ens33
virtual_router_id 51
# 权重低于MASTER
priority 80
advert_int 2
authentication {
auth_type PASS
auth_pass 1111
}
virtual_ipaddress {
# 注意:主备两台的vip都是一样的,绑定到同一个vip
192.168.1.161
}
}
二、双主热备

priority 100
advert_int 1
authentication {
auth_type PASS
auth_pass 1111
}
virtual_ipaddress {
192.168.1.161
}
}
vrrp_instance VI_2 {
state BACKUP
interface ens33
virtual_router_id 52
priority 80
advert_int 1
authentication {
auth_type PASS
auth_pass 1111
}
virtual_ipaddress {
192.168.1.162
}
}
global_defs {
router_id keep_172
}
vrrp_instance VI_1 {
state BACKUP
interface ens33
virtual_router_id 51
priority 80
advert_int 1
authentication {
auth_type PASS
auth_pass 1111
}
virtual_ipaddress {
192.168.1.161
}
}
vrrp_instance VI_2 {
state MASTER
interface ens33
virtual_router_id 52
priority 100
advert_int 1
authentication {
auth_type PASS
auth_pass 1111
}
virtual_ipaddress {
192.168.1.162
}
}
