參考：haproxy+keepalived(主從模式)實現高可用環境的簡單配置? ? ?https://blog.51cto.com/sf1314/2357735?主主模式就是需要兩個VIP,即兩個haproxy節點都同時在提供服務,
當有一個haproxy掛掉后,它的vip資源就會漂到另一個haproxy節點上(此時它將有兩個vip都在提供服務),故障轉移無感知.

[root@Haproxy_Keepalived_Master ~]# vim /etc/keepalived/keepalived.conf
! Configuration File?for?keepalived
global_defs {
??notification_email {
????root@localhost
????}
?notification_email_from keepalived@localhost
smtp_server 127.0.0.1
smtp_connect_timeout 30
router_id HAproxy237
}
?vrrp_script chk_haproxy {???????????????????????????????????#HAproxy 服務監控腳本????????????????????
??script?"/etc/keepalived/check_haproxy.sh"
??interval 2
??weight 2
}
?vrrp_instance VI_1 {
??state MASTER
??interface eth0
??virtual_router_id 51
??priority 100
??advert_int 1
??authentication {
????auth_type PASS
????auth_pass 1111
}
??track_script {
????chk_haproxy
}
virtual_ipaddress {
????182.148.15.239
}
notify_master?"/etc/keepalived/clean_arp.sh 182.148.15.239"
}
vrrp_instance VI_2 {
??state BACKUP
??interface eth0
??virtual_router_id 52
??priority 99
??advert_int 1
??authentication {
????auth_type PASS
????auth_pass 1111
}
virtual_ipaddress {
??182.148.15.235
}
notify_master?"/etc/keepalived/clean_arp.sh 182.148.15.235"
}
??3）Haproxy_Keepalived_Backup服務器上的Keepalived配置如下：
[root@Haproxy_Keepalived_Backup ~]# /etc/keepalived/keepalived.conf /etc/keepalived/keepalived.conf-bak
[root@Haproxy_Keepalived_Backup ~]# vim /etc/keepalived/keepalived.conf
! Configuration File?for?keepalived
global_defs {
??notification_email {
????root@localhost
????}
?notification_email_from keepalived@localhost
smtp_server 127.0.0.1
smtp_connect_timeout 30
router_id HAproxy236
}
?vrrp_script chk_haproxy {????????????????????????????
??script?"/etc/keepalived/check_haproxy.sh"
??interval 2
??weight 2
}
?vrrp_instance VI_1 {
??state BACKUP
??interface eth0
??virtual_router_id 51
??priority 99
??advert_int 1
??authentication {
????auth_type PASS
????auth_pass 1111
}
??track_script {
????chk_haproxy
}
virtual_ipaddress {
????182.148.15.239
}
notify_master?"/etc/keepalived/clean_arp.sh 182.148.15.239"
}
vrrp_instance VI_2 {
??state MASTER
??interface eth0
??virtual_router_id 52
??priority 100
??advert_int 1
??authentication {
????auth_type PASS
????auth_pass 1111
}
virtual_ipaddress {
??182.148.15.235
}
notify_master?"/etc/keepalived/clean_arp.sh 182.148.15.235"
}
