## 1.换源

```bash
CentOS-AltArch的镜像地址为：https://repo.huaweicloud.com/centos-altarch/
1、备份配置文件：
cp -a /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak
2、下载新的CentOS-Base.repo文件到/etc/yum.repos.d/目录下（因gpgkey无法动态适配，已将gpgcheck设置为0，关闭校验，如需打开请设置为1，并修改gpgkey地址），执行如下命令：
wget -O /etc/yum.repos.d/CentOS-Base.repo https://repo.huaweicloud.com/repository/conf/CentOS-AltArch-7.repo
3、执行yum clean all清除原有yum缓存。
4、执行yum makecache（刷新缓存）或者yum repolist all（查看所有配置可以使用的文件，会自动刷新缓存）。

```

## 2.安装依赖

```bash
执行以下命令，安装图形桌面组件。
# yum groupinstall "Server with GUI" -y
说明：
如果安装结束后提示Failed : python -urllibs3.noarch 0:1.10.2-7.e17,可以执行以下命令：

mv /usr/lib/python2.7/site-packages/urllib3/packages/ssl_match_hostname /usr/lib/python2.7/site-packages/urllib3/packages/ssl_match_hostname.bak

yum install python-urllib3 -y

```
