Centos7（实验笔记）

Yum本地源
1．挂载Linux安装光盘到目录/mnt/cdrom
[root@centos ~]# mkdir /mnt/cdrom
[root@centos ~]# mount /dev/cdrom /mnt/cdrom
mount: /dev/sr0 is write-protected, mounting read-only
2．创建软件仓库配置文件/etc/yum.repos.d/CentOS.repo
[root@centos ~]# mkdir /etc/yum.repos.d/repo_bak
[root@centos ~]# mv /etc/yum.repos.d/*.repo /etc/yum.repos.d/repo_bak
// 将系统原有的软件仓库配置文件转移到目录/etc/yum.repos.d/repo_bak
[root@centos ~]# vi /etc/yum.repos.d/CentOS.repo
