Activemq Artemis无法建立Netty连接

Question

当ActiveMQ Artemis试图建立Netty连接时，我会失败。我显示以下日志。我检查了主机是否可以解析，并且是。我的主人是一个kubernetes豆荚，我正在运行一组4个豆荚

Answer 1

java.net.unknownhostexception这里来自JVM本身：

java.base/java.net.InetAddress$CachedAddresses.get

Netty或ActiveMQ Artemis对此无能为力。根据 javadoc ：

投掷以表明无法确定主机的IP地址。

这个问题几乎可以肯定是环境的，尽管从技术上讲，这也可能是JVM中的错误。

Answer 2

尝试使用cmd ping hostName ping主机ping
如果ping不起作用，请执行以下步骤

1. 配置主机文件中存在的主机，该文件中存在的位置C：\ Windows \ system32 \ drivers \ etc etc

   例如 - 192.168.202.7 test.xyz.com

2. 在服务器端也这样做。
3. 重新启动服务器。
4. 尝试再次使用服务器。

通过遵循上述步骤，此问题将得到解决。
