离线安装报这个错误，麻烦帮忙看下什么问题？

看样子是pip源的问题
如果没有用glusterfs的话，可以在kubesphere/roles/prepare/nodes/tasks/main.yaml中注释掉glusterfs相关的任务。

v3.0.0已发布，可以试试

      Cauchy 感谢回复！但尝试注释以后得到了同样的结果。
      umount: /kubeinstaller/yum_repo/iso: mountpoint not found这行提示是否提示我未将镜像文件放到yum_repo中呢？

          fnag_huna

          这个只是说明umount的时候没有对应的挂载点。
          还是那个pip | Installing pip报错吗？注释掉的话应该就不会执行那个task了呀。

              Cauchy 我没有找到您说的这一行在哪里，我的报错信息一直是这样的

                  fnag_huna

                  那应该是不支持的，可以尝试把Repos/centos-7.7-amd64.iso改成centos-7.8-amd64.iso试试。
                  如果不行的话就装v3.0.0吧。

                      Cauchy 改成7.8以后成功开始安装了，非常感谢！但是现在出现了这样的状况，是在拉镜像拉不下来吗？我用的代理，wget能通网，但不知道为什么这里的镜像无法拉取，望解惑
                      又仔细看了一眼地址，感觉是在本地拉取的镜像？那为何无法拉取呢？

                          fnag_huna
                          可以执行docker info看下docker的配置，是不是这个本地仓库的地址没有加到docker的insecure_registries中。

                              Cauchy 看了一下，里面是有本地仓库地址的：Insecure Registries: 192.168.2.32:5000 127.0.0.0/8这是什么原因呢

                                  fnag_huna
                                  先docker ps | grep registry检查下这个仓库服务是否正常，然后push个镜像试下是否能成功。

                                      Cauchy 顺带一提，我现在安装的是 all-in-one 单节点模式的，之前尝试安装多节点时出现了这样的情况
                                      我的hosts.ini配置是这样的：
                                      请问是哪里出问题了？

                                        fnag_huna
                                        看起来是registry服务不正常，可以重启下这个容器试试。
                                        上边那个ssh连接不到远程机器的问题应该是机器上留存了旧的连接信息。可以把/.ssh/known_hosts删掉试试。
