3修改配置文件如下

[root@M128 ~]# vim /etc/keepalived/keepalived.conf

global_defs {

? ? notification_email {

?jikaituo@126.com

? ? }

? ? notification_email_from jikaituo@126.com

? ? ? smtp_server smtp.126.com ? # 郵件服務(wù)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宕掉重啟haproxy服務(wù)] ?

? ? interval ? ? ? ?5 ? ? ? ? ? ? ? ? ? ? # 腳本執(zhí)行間隔 ?

? ? weight ? ? ? ? -5 ? ? ? ? ? ? ? ? ? ?# 執(zhí)行腳本后優(yōu)先級變更：5表示優(yōu)先級+5;-5則表示優(yōu)先級-5

}

vrrp_instance VI_A {

? ? state MASTER ? ? ? ? ? ? ? ? ? ?# 主上此值為MASTER,從上為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(shù)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

? ? }

}
