ubuntu - 节点 'riak@192.168.1.218' 未响应 ping

Question

我不知道系统发生了什么，但是当我突然发出 riak start它不再开始了。我得到这个输出。

如果我发出 riak 控制台，我不会收到任何 ping 响应。
我不知道该怎么办，所以请告知如何使系统重新联机。

所以这里的整个过程就是

出于某种原因，机器 riak

上的 IP 已更改

IP 被硬编码在/etc/riak/vm.args 和/etc/riak/app.config

复活的过程如下:

编辑并设置上述文件中的新 IP

sudo rm -rf /var/lib/riak/ring/* # delete the riak ring

重新启动机器或执行以下步骤:

riak-admin cluster force-replace riak@127.0.0.1 riak@"主机名-i " # replace the name

riak start # start the node
