centos8发行版通过 BaseOS 和应用流 (AppStream) 仓库发布，AppStream 是对传统 rpm 格式的全新扩展，为一个组件同时提供多个主要版本

centos8 自带封装了NGINX，这篇文章给大家介绍CentOS8 配置本地yum源，具体内容如下所示：

1、创建目录

mkdir /mnt/cdrom

2.挂载你的cdrom文件。

2、光驱方式

采用光驱的方式，对于vmware用户来说，可以直接用镜像，如图所示

然后进入目录，只要能够列出如下的文件说明挂载成功。

3、 进入/etc/yum.repos.d目录

4、编辑 CentOS-Linux-Media.repo

文件按照如下的方式修改，修改有6个地方
baseurl ，指定挂载的目录下的BaseOS 以及AppStream目录
gpgcheck 即不校验
enabled 启用该镜像

5、屏蔽默认的镜像

vim进入如下的3个文件,然后修改enabled=0；

大概如下所示 ：如果日后希望使用网络的方式安装包，记得重新把这里修改为1 即重新启用。

6、清空cache，并重新创建cache

7、验证结果

7、开机自动挂盘

为了避免重启后，镜像源无法访问的问题。我们需要将挂盘的操作配置在我们的/etc/fstab文件中

7.1 使用mount -l 查看我们挂的盘的信息

从上面可以得到5个信息

/dev/cdrom /mnt/cdrom iso9660 defaults 0 0

其实也可以写成这样

/dev/cdrom /mnt/cdrom autodefaults 0 0

设备名是我经过链接过的，这里可以填写sr0就好了,但是我还是写/dev/cdrom

7.2 将信息配置入/etc/fstab文件中
