example

我们的环境里 service A,nacos 服务端, client a 都在不同的机器上部署,nacos 所在机器开放了对应的 8848,9848,9849 端口。目前遇到的问题是:

  1. client a 通过服务发现调用 service A 时,报错 service A 找不到。client a 的 nacos 日志里相关的错误是"do not have useful host"
  2. 本地手动调用 SubscribeService ,返回的 service A 相关的数据里,host 字段为空,其它字段正常
  3. 检查 service A 的 nacos 日志,未发现错误
  4. 检查 nacos 服务端的日志,在 naming-push.log 里发现了大量的 PUSH-FAIL,原因是超时

我主要有这两个疑问:
1. 根据以往的 issue 来看,应该是端口不通导致的 PUSH-FAIL。但为什么只有 host 字段没有数据呢?
2. service A 和 client a 所在的机器是否必须对 nacos 服务端所在的机器开放所有端口的访问权限?(因为服务重启后端口会改变,似乎没有固定端口的配置项)

host和服务实例相关,检查service A的实例是否健康

service A 服务是正常的,nacos sdk 的日志里健康检查相关的请求没有错误。还有那个方向可以排查下呢?

nacos控制台上能看到服务实例的host么?(一般是ip地址)

服务变成了下线的状态(原因还不确定),我们手动上线后可以调通了。请问 nacos 是否会自动下线服务呢?

nacos不会自动下线服务, 控制台看到他是下线就是两种情况:

  1. 注册的时候, 设置了instance的enabled=false
  2. 调用了更新实例接口,修改了enabled=false

No more response from author for a long time, and this problem seems usage problem.
