小编使用的是在ESXI上挂载的虚拟机 (VsPhereClient5.5),挂载光驱比较简单。
如阅读者使用其它软件安装的虚拟机,请自行百度查询挂载光驱方式。
(小编就不在阐述VsPhere挂载光驱的方式,直接上正文!!!)
挂载光驱及永久保存步骤:
[[email protected] ~]# mkdir cdrom 先建立一份空目录
[[email protected] ~]# ls -l /dev/sr* 查询系统是否其它的外置设备 (*):是通配符
brw-rw----. 1 root cdrom 11, 0 Feb 23 10:15 /dev/sr0
[[email protected] ~]# mount /dev/sr0 cdrom/ 挂载到cdrom目录下
mount: /dev/sr0 is write-protected, mounting read-only 挂载光驱只有读取的权限
[[email protected] ~]#
[[email protected] ~]# df -T 查询所有磁盘信息包括系统类型
Filesystem Type 1K-blocks Used Available Use% Mounted on
/dev/mapper/centos-root xfs 17811456 998352 16813104 6% /

tmpfs tmpfs 188392 0 188392 0% /run/user/0
/dev/sr0 iso9660 4414592 4414592 0 100% /root/cdrom 这个是刚才小编挂载的光驱
系统重新启动后挂载的光驱就会失效,想要一直保存下去,需要更改 /etc/fstab 这份配置文件
[[email protected] ~]# vi /etc/fstab
#

/dev/sr0 /cdrom iso9660 defaults 0 0
外部装置名称 挂载的目录 系统类型 默认值 再不济,可以照葫芦画瓢也能画出来O(∩_∩)O哈哈~
目前,永久保存挂载点的信息已经修改完成, 接下来进入使用本地光驱制作yum源
使用本地光驱制作yum源步骤:
1: 建议备份 /etc/yum.repos.d 目录下的所有文件。
2: 删除 /etc/yum.repos.d目录下的所有文件。
3: 在 /ect/yum.repos.d目录下建议一份尾缀名为 .repo的文件,进行编辑。
[[email protected] ~]# cp -r /etc/yum.repos.d/ /
[[email protected] ~]# ls /
bin boot dev etc home ifcfg-ens160 lib lib64 media mnt opt proc root run sbin srv sys tmp usr var yum.repos.d
[[email protected] ~]# rm -rf /etc/yum.repos.d/*
[[email protected] ~]# touch /etc/yum.repos.d/dvd.repo
[[email protected] ~]# vi /etc/yum.repos.d/dvd.repo
[ABC]
name=install ABC
baseurl=file:///cdrom
enabled=1
gpgcheck=0
回到Shell 输入:yum makecache 刷新repos生成缓存
可是尝试重新启动系统后再shell中输入: df -T 去查询光驱是否存在
[[email protected] ~]# yum install gcc 可以安装这个包试试看有没有成功
