参考：haproxy+keepalived(主从模式)实现高可用环境的简单配置     https://blog.51cto.com/sf1314/2357735 

[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 服务监控脚本                    

   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服务器上的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"

}
