Question

我不知道系统发生了什么，但是当我发出riak start时它突然不再启动了。我得到了这个输出。

如果我发出riak控制台，我对ping没有反应。我不知道该怎么做，所以请告知如何让系统恢复在线状态。

Answer 1

所以整个过程就是

由于某种原因，在机器riak上更改了IP
IP在/etc/riak/vm.args和/etc/riak/app.config

恢复的过程如下：

在上述文件中编辑和设置新IP
sudo rm -rf /var/lib/riak/ring/* # delete the riak ring
重启机器或执行以下步骤：
riak-admin cluster force-replace riak@127.0.0.1 riak@" hostname -i " # replace the name
riak start # start the node

此主题还与此问题相关联：Riak node no longer working after changing IP address

Answer 2

启动新的riak节点的简单方法是在riak容器bash上运行riak控制台。

1. If riak is a container in your docker then follow this procedure (MAC)
a. get riak image id <docker ps --all>
b. run bash command <docker exec -it "riak-container-id" bash>
c. run <riak console> this initiates a new riak node console
d. open another terminal and run <riak-shell>
e. run command<connect use your node created at step c> it will look like 
riak@10.1.0.216

你去了。
