Centos8 yum源
1、环境
运行环境：VMware16pro + centos8.3
2、配置步骤
❶创建挂载点
[root@centos1905 ~]# mkdir -p /mnt/cdrom
❷挂载ISO镜像文件
（1） VMware Workstation接入ISO镜像文件
（2） 进行光驱挂载
[root@centos1905 ~]# mount /dev/cdrom /mnt/cdrom
mount: /mnt/cdrom: WARNING: device write-protected, mounted read-only.
（3）验证挂载
[root@centos1905 ~]# ls /mnt/cdrom/
AppStream BaseOS EFI images isolinux media.repo TRANS.TBL
❸编写本地yum源仓库文件
在编写之前，先将yum配置文件进行备份！
[root@centos1905 ~]# cd /etc/yum.repos.d/
[root@centos1905 yum.repos.d]# mkdir repo_bak
[root@centos1905 yum.repos.d]# mv *.repo repo_bak/
编写本地yum仓库文件
[root@centos1905 yum.repos.d]# vi /etc/yum.repos.d/centos8.repo
[c8-media-AppStream]
name=AppStream
baseurl=file:///mnt/cdrom/AppStream
gpgcheck=0
enabled=1
[c8-media-BaseOS]
name=BaseOS
baseurl=file:///mnt/cdrom/BaseOS
gpgcheck=0
enabled=1
❹清空并重建cache
[root@centos1905 yum.repos.d]# yum clean all
0 files removed
[root@centos1905 yum.repos.d]# yum makecache
AppStream 58 MB/s | 5.2 MB 00:00
BaseOS 44 MB/s | 2.2 MB 00:00
Metadata cache created.
❺写入配置文件
[root@centos1905 yum.repos.d]# echo "/dev/cdrom /mnt/cdrom iso9660 defaults 0 0" >> /etc/fstab
❻测试
[root@centos1905 yum.repos.d]# yum install gnome-tweaks

3、卸载步骤
❶切换至配置文件目录
[root@centos1905 ~]# cd /etc/yum.repos.d/
❷将本地yum源转存备份
[root@centos1905 yum.repos.d]# mkdir local_yum
[root@centos1905 yum.repos.d]# mv centos8.repo local_yum/
❸还原yum源
[root@centos1905 yum.repos.d]# cd /etc/yum.repos.d/repo_bak
[root@centos1905 repo_bak]# mv *.repo /etc/yum.repos.d
❹安装测试
[root@centos1905 ~]# cd /etc/yum.repos.d/
[root@centos1905 yum.repos.d]# ls -al
total 20
drwxr-xr-x. 3 root root 42 Mar 11 11:31 .
drwxr-xr-x. 134 root root 8192 Mar 11 10:47 ..
-rw-r--r--. 1 root root 179 Mar 11 11:31 centos8.repo
drwxr-xr-x. 2 root root 4096 Mar 6 13:29 repo_bak
[root@centos1905 yum.repos.d]# mkdir local_yum
[root@centos1905 yum.repos.d]# mv centos8.repo local_yum/
[root@centos1905 yum.repos.d]# cd /etc/yum.repos.d/repo_bak
[root@centos1905 repo_bak]# mv *.repo /etc/yum.repos.d
[root@centos1905 repo_bak]# yum install mysql
CentOS-8 - AppStream 543 kB/s | 6.3 MB 00:11

略
Centos7 yum源
1、进入yum配置文件目录
cd /etc/yum.repos.d/
2、创建新配置文件
vim centos7.repo
3、按照参数路径挂载
mkdir -p /media/cdrommount /dev/cdrom /media/cdrom
4、挂载信息写入配置文件
vim /etc/fstabmount -a
[root@localhost ~]# cd /etc/yum.repos.d/
[root@localhost yum.repos.d]# vim centos7.repo
[centos7]
name=centos7
baseurl=file:///media/cdrom
enabled=1
gpgcheck=0
[root@localhost yum.repos.d]# mkdir -p /media/cdrom
[root@localhost yum.repos.d]# mount /dev/cdrom /media/cdrom
mount: /dev/sr0 写保护，将以只读方式挂载
[root@localhost yum.repos.d]# vim /etc/fstab
/dev/cdrom /media/cdrom iso9660 defaults 0 0
[root@localhost yum.repos.d]# mount -a
[root@localhost yum.repos.d]# yum install httpd
Centos6 yum源
运行环境：VMware16pro + centos6.6
1、进入yum配置文件目录
[root@www nginx-1.6.3]# cd /etc/yum.repos.d/
2、备份配置文件
[root@www yum.repos.d]# mv CentOS-Base.repo CentOS-Base.repo.bak
3、创建新的配置文件
[root@www yum.repos.d]# vim CentOS-Base.repo
# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
