Rocky Linux 更新本地镜像源

要将 Rocky Linux 的本地镜像源更新为阿里云，你可以按照以下步骤进行操作：

打开终端或 SSH 连接到 Rocky Linux 的服务器。
进入 /etc/yum.repos.d/ 目录，该目录包含 Rocky Linux 的 yum 配置文件。
```
cd /etc/yum.repos.d/
```
备份当前的 yum 配置文件，以防万一需要还原。
```
sudo cp *.repo *.repo.bak
```
使用文本编辑器（如 vi 或 nano）打开 Rocky Linux 的 yum 配置文件。
```
sudo vi Rocky.repo
```
如果你使用的是 Rocky Linux 8，那么配置文件的名称可能是 rocky8.repo。
在打开的文件中，找到以 [base] 开头的部分，通常是一个名为 rocky-base.repo 或类似的节。
在该节中，找到 baseurl 行，并将其注释掉（在行前面添加 #）。
```
# baseurl=http://...
```
在注释掉的 baseurl 行下方添加阿里云的镜像源地址。你可以根据你所在的地区选择合适的镜像源地址。以下是一些常用的阿里云镜像源地址：
- 阿里云中国大陆镜像源：
```
baseurl=http://mirrors.aliyun.com/rocky/$releasever/BaseOS/$basearch/os/
```
请注意，上述地址中的 $releasever 和 $basearch 是变量，会被实际的版本号和架构替换。
保存并关闭文件。
清除 yum 缓存。
```
sudo yum clean all
```
更新 yum 缓存并安装软件包。
```
sudo yum update
```

#
# The mirrorlist system uses the connecting IP address of the client and the
# update status of each mirror to pick current mirrors that are geographically
# close to the client.  You should use this for Rocky updates unless you are
# manually picking other mirrors.
#
# If the mirrorlist does not work for you, you can try the commented out
# baseurl line instead.
