主主模式就是需要两个VIP,即两个haproxy节点都同时在提供服务,

当有一个haproxy挂掉后,它的vip资源就会漂到另一个haproxy节点上(此时它将有两个vip都在提供服务),故障转移无感知.

`[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"`

`}`
