CCE使用node节点使用VIP

背景：想在节点上使用VIP，将nodeport服务做到高可用。启动VIP后发现访问失败

启动服务

-- 30007集群nodeport服务，8080 NGINX，任意一个节点启动# 测试结果如下
-- RIP
10.1.0.60:80 OK
10.1.0.60:30007 OK-- VIP
10.1.0.88:80 OK
10.1.0.88:30007 NOT OK

检查发现node节点并没有监听30007端口，而是通过ipvs添加了被负载均衡的虚拟地址。

[root@recovery-test-28141 ~]# ipvsadm -Ln | grep 30007 -A3
