centos9ISO镜像及yum源配置文件
配置CentOS的Yum源包括使用默认的官方源或替换为第三方源。以下是配置Yum源的基本步骤:
1. 备份原有的yum源配置文件:
```bash
sudo mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
```
2. 创建一个新的Yum源配置文件:
```bash
sudo vi /etc/yum.repos.d/CentOS-Base.repo
```
3. 在新配置文件中添加你选择的Yum源信息。这里以阿里云的CentOS镜像源为例:
```ini
[base]
name=CentOS-$releasever - Base
baseurl=http://mirrors.aliyun.com/centos/$releasever/os/$basearch/
gpgcheck=1
gpgkey=http://mirrors.aliyun.com/centos/RPM- Updates
baseurl=http://mirrors.aliyun.com/centos/$releasever/updates/$basearch/
gpgcheck=1
gpgkey=http://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-Official
[extras]
name=CentOS-$releasever - Extras
baseurl=http://mirrors.aliyun.com/centos/$releasever/extras/$basearch/
gpgcheck=1
gpgkey=http://mirrors.aliyun.com/centos/RPM- Plus
baseurl=http://mirrors.aliyun.com/centos/$releasever/centosplus/$basearch/
gpgcheck=1
enabled=0
gpgkey=http://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-Official
[contrib]
name=CentOS-$releasever - Contrib
baseurl=http://mirrors.aliyun.com/centos/$releasever/contrib/$basearch/
gpgcheck=1
enabled=0
gpgkey=http://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-Official
```
注意:请根据你的实际需求选择合适的Yum源,并替换上述URL为相应源的URL。
4. 清理Yum缓存,并生成新的缓存,以确保新的源能够被正确使用:
```bash
sudo yum clean all
sudo yum makecache
```
配置完成之后,你可以使用`yum repolist`命令来查看当前配置的Yum源,并进行包管理操作。
