Linux学习-通过光盘配置本地yum源

本例通过虚拟机Centos6系统完成

1. 先确认光驱已存在光盘，并且设备的状态是已连接。
   
2. 挂载光盘到本地目录

#挂载光盘到本地目录
[root@localhost ~]# mount /dev/sr0 /mnt
mount: block device /dev/sr0 is write-protected, mounting read-only

3. 进入到/etc/yum.repos.d目录，配置repo文件

[root@localhost mnt]# cd /etc/yum.repos.d
[root@localhost yum.repos.d]# 
[root@localhost yum.repos.d]# mkdir bak
[root@localhost yum.repos.d]# mv *.repo bak
[root@localhost yum.repos.d]# vi local.repo
#local.repo文件内容
[CentOS-dvd]
name=Centos $releasever - DVD
baseurl=file:///mnt/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/REM-GPG-KEY-CentOS-6
#复制REM-GPG-KEY-CentOS-6文件到/etc/pki/rpm-gpg/目录
[root@localhost mnt]# cp RPM-GPG-KEY-CentOS-6 /etc/pki/rpm-gpg/REM-GPG-KEY-CentOS-6
[root@localhost yum.repos.d]# yum makecache

4. 安装软件测试

[root@localhost mnt]# yum install -y man
