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。

然后进入目录,只要能够列出如下的文件说明挂载成功。

Centos8 配置本地yum源_CentOS_02


3、 进入/etc/yum.repos.d目录


Centos8 配置本地yum源_centos_03


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

Centos8 配置本地yum源_ci_04

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。

# baseurl line instead.

6、清空cache,并重新创建cache

Centos8 配置本地yum源_centos_05

7、验证结果

Centos8 配置本地yum源_CentOS_06



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

Centos8 配置本地yum源_centos_07

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

Centos8 配置本地yum源_CentOS_08
