配置Nacos + Nginx + Spring Cloud出的问题

在没有加入nginx前,我的nacos启动是以单机模式启动
这是Linux的这个ip地址

img

在idea启动微服务,测试数据的时候用的是这个IP地址发送请求。

开启nginx后,我的nacos启动是以集群模式启动
启动微服务经常报这个错,而且我Nacos页面可以成功访问,就是偶尔注册不了服务,经常报下面的错,偶尔又好了

还有一个问题就是,注册服务成功后,下面图中ip是我本地电脑的ip,而不是LInux的ip地址

img

我在测试数据时原本用192.168.46.130失效了,必须用192.168.46.1才能访问发送请求
这是为什么?哪怕我用spring.cloud.nacos.discovery.ip=192.168.46.130,把上述图ip改成192.168.46.130,启动就直接报错了,求解?

以下是我的各种配置文件的配置,我配置了3个nacos端口不同
它们的application.properties文件是这样的

img


它们的cluster.conf文件都是这样的

img

而nginx的配置文件是这样的

img

刚开始接触这些,不晓得哪里错了,根据教程一点点摸索,但就是不明白。
1.就是为什么报错?而且有时候好了,有时候又一直不行。
2.为什么单机模式下ip一致都是linux的,而集群模式下,访问ip就变成我本地的

    关注

    1.如果访问ip要于linux系统的一致,需要在本地修改hosts文件绑定.
    2.你的nacos以集群模式启动,你看看你的配置文件中有没有配置集群模式,Nginx有没有负载均衡
