关于机器端口限制导致的 PUSH-FAIL 问题 #12697
Comments
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:

No more response from author for a long time, and this problem seems usage problem. |
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:
SubscribeService
,返回的 service A 相关的数据里,host
字段为空,其它字段正常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)
