通過掛載系統光盤鏡像搭建本地YUM倉庫

掛載系統光盤鏡像的兩種方式

1、通過光驅掛載
2、通過ISO鏡像掛載

[root@aiqu1 ~]# mkdir /mnt/cdrom   #創建掛載目錄
[root@aiqu1 ~]# mount /dev/cdrom /mnt/cdrom   //掛載光盤
或
[root@aiqu1 ~]# mount -o loop -t iso9660 /home/hj/CentOS-7-x86_64-DVD-1804.iso /var/www/html/CentOS7 #掛載ISO鏡像文件
[root@aiqu1 ~]# cd /etc/yum.repos.d/    #進入YUM庫所在目錄
將yum庫目錄中的文件修改後綴名，保留CentOS-Media.repo 文件，方便yum庫索引，純內網下提高效率
[root@aiqu1 yum.repos.d]# mv CentOS-Base.repo CentOS-Base.repo.bak
[root@aiqu1 yum.repos.d]# mv CentOS-Debuginfo.repo CentOS-Debuginfo.repo.bak
[root@aiqu1 yum.repos.d]# mv CentOS-Vault.repo CentOS-Vault.repo.bak
[root@aiqu1 yum.repos.d]# mv CentOS-CR.repo CentOS-CR.repo.bak
[root@aiqu1 yum.repos.d]# mv CentOS-fasttrack.repo CentOS-fasttrack.repo.bak
[root@aiqu1 yum.repos.d]# mv CentOS-Sources.repo CentOS-Sources.repo.bak
[root@aiqu1 yum.repos.d]# cp CentOS-Media.repo CentOS-Media.repo.bak #備份CentOS-Media.repo 文件
[root@aiqu1 yum.repos.d]# cat /etc/yum.repos.d/CentOS-Base.repo  #修改YUM庫

[root@aiqu1 ~]# yum -y install httpd ##一方面測試YUM庫能否安裝軟件，一方面需要一個web服務器，支持本地系統使用本地YUM源
[root@aiqu1 ~]# ln -s /mnt/cdrom/ /var/www/html/CentOS7 //掛載之後創建軟鏈接到/var/www/html
或
[root@aiqu1 ~]# mkdir -p /var/www/html/CentOS
[root@aiqu1 ~]# cp -R /var/www/html/CentOS7 /var/www/html/CentOS

執行 yum repolist 查看yum源信息

[root@aiqu1 ~]# yum repolist
