Keepalive+Nginx搭建主從負載服務器

keepalive+nginx搭建主從負載服務器

keepalive配置文件 從：

! Configuration File for keepalived
global_defs {
   notification_email {
   [email protected]
        }
   notification_email_from [email protected]
   smtp_server mail.yaoshi.com
   smtp_connect_timeout 30
   router_id LVS_DEVEL
}
vrrp_instance VI_1 {
    state MASTER
    interface eth0
    virtual_router_id 51
    mcast_src_ip 192.168.11.39
    priority 80
    advert_int 1
    authentication {
        auth_type PASS
        auth_pass chtopnet
    }
    virtual_ipaddress {
        192.168.11.208
    }
}

keepalive 主：

        }
   notification_email_from [email protected]
   smtp_server mail.yaoshi.com

   router_id LVS_DEVEL
}
vrrp_instance VI_1 {
    state MASTER
    interface eth0
    virtual_router_id 51
    mcast_src_ip 192.168.11.27
    priority 100
    advert_int 1
    authentication {
        auth_type PASS
        auth_pass chtopnet
    }
    virtual_ipaddress {
        192.168.11.208
    }
}
