 进入 Linux 系统，编辑配置文件
 
+**Centos 7 的配置文件一般在 `/etc/sysconfig/network-scripts` 下，Centos 9 的在 `/etc/NetworkManager/system-connections`，具体的配置名可使用 `ip addr` 查看就行**
+
+### Centos 7
+
 ```bash
 vi /etc/sysconfig/network-scripts/ifcfg-ens33
 ```
 
 1. 将 `BOOTPROTO="dncp"` 改为 `BOOTPROTO="static"`
 2. 新增下图的四个配置
 
-- dhcp：表示自动获取IP
-- static：静态IP
-- IPADDR：IP地址，就是常规访问的ip，必须保证在前面所设置的 192.168.xx.0 ~ 192.168.xx.254 之间
+- dhcp：表示自动获取 IP
+- static：静态 IP
+- IPADDR：IP 地址，就是常规访问的 ip，必须保证在前面所设置的 192.168.xx.0 ~ 192.168.xx.254 之间
 - NETMASK：子网掩码，必须为 255.255.255.0
 - GATEWAY：网关，与刚才 NAT 设置中的网关 IP 保持一致
 - DNS1：域名解析服务器，与网关保持一致即可

+## 设置镜像 yum 源
+
+### Centos 7
+
+参照 https://www.cnblogs.com/kohler21/p/18331060 即可

+先找到配置 yum 源的文件
+
+```bash
+cd /etc/yum.repos.d
+ls
+```
+
+拷贝两个文件以防万一
+
+```bash
+cp /etc/yum.repos.d/centos.repo /etc/yum.repos.d/centos.repo.backup-20250827
