3修改配置文件如下
[root@M128 ~]# vim /etc/keepalived/keepalived.conf
global_defs {
notification_email {
}
notification_email_from [email protected]
smtp_server smtp.126.com # 郵件服務器地址
smtp_connect_timeout 30 # 連接超時時間
router_id LVS_Master
}
vrrp_script chk_http_port {
script "/etc/keepalived/check_haproxy.sh" # haproxy運行檢測腳本[haproxy宕掉重啓haproxy服務]
interval 5 # 腳本執行間隔
weight -5 # 執行腳本後優先級變更：5表示優先級+5;-5則表示優先級-5
}
vrrp_instance VI_A {
state MASTER # 主上此值爲MASTER,從上爲BACKUP
interface eth0
virtual_router_id 50 # 此值主從必須一致
priority 100
advert_int 1
authentication { # authentication兩個參數值,主從也必須一致
auth_type PASS
auth_pass yiban
}
track_script {
chk_http_port
}
virtual_ipaddress {
192.168.78.220
}
}
5啓動keepalived
