<h2>7、主机清理</h2>

按这里提供的脚本,把主机环境清理
熹先生:
@Ksd 刚才是几个机器同名,忘记改了,现在改过来重启过。 还是刚才的状态,集群没有建立起来,还有什么地方有问题吗?
以前测试过,一个机器安装3个功能,然后其余机器都装worker,是正常的
现在想试试用3台机器只做ETCD CONTROL两个角色的集群,没成功
Ksd:
@熹先生 如果可以的话,按照 <a href="https://docs.rancher.cn/docs/rancher2/cluster-admin/cleaning-cluster-nodes/_index/">https://docs.rancher.cn/docs/rancher2/cluster-admin/cleaning-cluster-nodes/_index/</a> 里提供的脚本,把主机环境清理下
因为你修改了主机名,然后再重启的,可能会有一些数据链对不上了
Ksd:
但清理前得看看脚本,以免删除了你需要的数据
熹先生:
我直接恢复快照改好名字再测试下
王明阳:
改了主机名,,签发的证书就对不上了,只能清理系统,重新安装</p>
<h2>8、将 Kubernetes 证书文件全部清空了咋办?在线等!</h2>
