keepalived主主模式

keepalived主主模式

proxy1 192.168.146.130

proxy2 192.168.146.131

VIP1 192.168.146.100

VIP2 192.168.146.101

实现原理就是两个虚拟ip分别再两台主机上 （如图）

proxy1做主 proxy做从

proxy2做主 proxy做从

配置proxy1

[root@master keepalived]# cat keepalived.conf
! Configuration File for keepalived

global_defs {
notification_email {
acassen@firewall.loc
failover@firewall.loc
sysadmin@firewall.loc
}
notification_email_from Alexandre.Cassen@firewall.loc
smtp_server 192.168.200.1
smtp_connect_timeout 30
router_id proxy1
vrrp_skip_check_adv_addr
vrrp_strict
vrrp_garp_interval 0
vrrp_gna_interval 0
vrrp_mcast_group4 224.1.1.1
}

vrrp_instance VI_1 {
state MASTER
interface ens33
virtual_router_id 51
priority 100
advert_int 1
authentication {
auth_type PASS
auth_pass 1111
}
virtual_ipaddress {
192.168.146.100
}
}
vrrp_instance VI_2 {
state BACKUP
interface ens33
virtual_router_id 52
priority 50
advert_int 1
authentication {
auth_type PASS
auth_pass 654321
}
virtual_ipaddress {
192.168.146.101
}
}

配置proxy2

[root@backup keepalived]# cat keepalived.conf
! Configuration File for keepalived

global_defs {
notification_email {
acassen@firewall.loc
failover@firewall.loc
sysadmin@firewall.loc
}
notification_email_from Alexandre.Cassen@firewall.loc
smtp_server 192.168.200.1
smtp_connect_timeout 30
router_id proxy2
vrrp_skip_check_adv_addr
vrrp_strict
vrrp_garp_interval 0
vrrp_gna_interval 0
vrrp_mcast_group4 224.1.1.1
}

vrrp_instance VI_1 {
state BACKUP
interface ens33
virtual_router_id 51
priority 50
advert_int 1
authentication {
auth_type PASS
auth_pass 1111
}
virtual_ipaddress {
192.168.146.100
}
}
vrrp_instance VI_2 {
state MASTER
interface ens33
virtual_router_id 52
priority 100
advert_int 1
authentication {
auth_type PASS
auth_pass 654321
}
virtual_ipaddress {
192.168.146.101
}
}

测试 （双主ip）

192.168.146.130

192.168.146.131

优先级都是100

关闭192.168.146.130 keepalive

另一台主服务器已经接管VIP

测试另一台主机 （关闭proxy1）

成功！哈哈
