不小心删除了kubesphere的mysql，导致kubesphere访问不了，如何恢复kubesphere，或者kubesphere如何重装，不影响k8s

    Forest-L 不好意思，没太明白你说的，我没有ks-installer这个pod，我是用kubekey安装的，您能说详细点么

        jwangkun

        kubectl -n kubesphere-system rollout restart deploy ks-installer

            [root@node1 hngc]# kubectl get deployment -n kubesphere-system
            NAME READY UP-TO-DATE AVAILABLE AGE
            etcd 0/1 1 0 86d
            ks-apiserver 1/3 1 1 86d
            ks-console 3/3 3 3 86d
            ks-controller-manager 3/3 3 3 86d
            ks-installer 1/1 1 1 86d
            minio 1/1 1 1 86d

            jwangkun
            1、kubectl edit cc -n kubesphere-system ks-installer 把mysql状态信息都删除，如mysql字样等下面三行内容删除。

            status:
  alerting:
    enabledTime: 2020-12-09T17:53:10CST
    status: enabled
  mysql:
    enabledTime: 2020-11-30T16:36:10CST
    status: enabled

            2、再执行如下语句，kubectl -n kubesphere-system rollout restart deploy ks-installer

                kubectl delete deployment mysql -n kubesphere-system
                kubectl delete deployment redis-ha-haproxy -n kubesphere-system
                kubectl delete minio redis-ha-haproxy -n kubesphere-system
                执行过这个三个

                  jwangkun 你删除这些干啥呢，redis mysql minio 都是集群依赖的数据库啊，这些删除了当然启动不了了

                      hongming [root@node1 hngc]# kubectl logs -f ks-apiserver-85445c576d-vcpq7
                      Error from server (NotFound): pods “ks-apiserver-85445c576d-vcpq7” not found

                        Jeff 这些启动报错，没想到是他系统依赖的，现在如何恢复呢

                            6 node(s) had volume node affinity conflict 看看这个，错误提示已经很清楚了
