LVS+keepalived简单搭建(二)

在LVS1的基础上进行搭建 https://www.cnblogs.com/hikoukay/p/12860476.html
keeplived主机 用node01,node04两台
先清掉原先node01的配置
　　ipvsadm -C 清掉原先配置
　　ifconfig eth0:8 down down掉原先配置
 node01,node04安装镜像源
　　yum install keepalived ipvsadm -y
完成之后做如下配置
    cd  /etc/keepalived/
    cp keepalived.conf keepalived.conf.bak
    vi keepalived.conf
        node01:
        vrrp：虚拟路由冗余协议！
            vrrp_instance VI_1 {
                state MASTER         //  node04设为  BACKUP
                interface eth0
                virtual_router_id 51
                priority 100         //     node04设为     50
                advert_int 1
                authentication {
                    auth_type PASS
                    auth_pass 1111
                }
                virtual_ipaddress {
                    192.168.65.110/24 dev eth0 label  eth0:3
                }
            }
        virtual_server 192.168.65.110 80 {
            delay_loop 6
            lb_algo rr
            lb_kind DR
            nat_mask 255.255.255.0
            persistence_timeout 0
            protocol TCP
 
            real_server 192.168.65.20 80 {
                weight 1
                HTTP_GET {
                    url {
                      path /
                      status_code 200
                    }
                    connect_timeout 3
                    nb_get_retry 3
                    delay_before_retry 3
                }
            }
            real_server 192.168.65.30 80 {
                weight 1
                HTTP_GET {
                    url {
                      path /
                      status_code 200
                    }
                    connect_timeout 3
                    nb_get_retry 3
                    delay_before_retry 3
                }
            }
　　　　　　}
        scp  ./keepalived.conf  root@node04: /etc/keepalived/keepalived.conf 远程复制,从node01将node01的keeplived配置文件复制到node04并改部分配置

配置好之后就可以启动了

　　service keepalived start

启动之后就可以访问了

　　用虚拟ip去访问 我这里是192.168.65.110

可以将主keepalived下线测试故障转移

　　访问确实不受影响
