你们对这个有什么想法吗?
Do you guys have any idea about this?
推荐答案
在/etc/hosts 文件中添加nimbus"作为 127.0.0.1 和 localhost 的别名.
Add "nimbus" to /etc/hosts file as alias to 127.0.0.1 and localhost.
确保 iptables 不是您所在主机的问题尝试运行或很可能你的 ~/.storm/storm.yaml 有问题
Make sure iptables is not the issue from the host you aretrying to run or Most likely there is something wrong in your ~/.storm/storm.yaml
