进行yum本地源配置之前,需要在虚拟机设置中将本地光盘设置为已连接状态
一旦关机仍需重新挂载(指令挂载)
su - root切换到管理员并切换到其家目录
[root@localhost ~]# mkdir /tmp/dvd [root@localhost ~]# mount /dev/cdrom /tmp/dvd mount: /dev/sr0 写保护,将以只读方式挂载 [root@localhost ~]# cd /tmp/dvd [root@localhost dvd]# cd Packages [root@localhost Packages]# cd /etc/yum.repos.d/ [root@localhost yum.repos.d]# ls CentOS-Base.repo CentOS-Debuginfo.repo CentOS-Media.repo CentOS-Vault.repo CentOS-CR.repo CentOS-fasttrack.repo CentOS-Sources.repo CentOS-x86_64-kernel.repo [root@localhost yum.repos.d]# cat 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. # # [base] name=CentOS-$releasever - Base mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os&infra=$infra #baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/ gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 #released updates [updates] name=CentOS-$releasever - Updates mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates&infra=$infra #baseurl=http://mirror.centos.org/centos/$releasever/updates/$basearch/ gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 #additional packages that may be useful [extras] name=CentOS-$releasever - Extras mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras&infra=$infra #baseurl=http://mirror.centos.org/centos/$releasever/extras/$basearch/ gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 #additional packages that extend functionality of existing packages [centosplus] name=CentOS-$releasever - Plus mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=centosplus&infra=$infra #baseurl=http://mirror.centos.org/centos/$releasever/centosplus/$basearch/ gpgcheck=1 enabled=0 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
[root@localhost Packages]# cd /etc/yum.repos.d/
[root@localhost ~]# cd /etc
[root@localhost etc]# cp -r yum.repos.d yum.repos.d_copy
[root@localhost etc]# cd yum.repos.d
[root@localhost yum.repos.d]# rm -f *
[root@localhost yum.repos.d]# ls
[root@localhost yum.repos.d]# vim dvd.repo
下面是dvd.repo内容:
[dvd]
name=dvd
baseurl=file:///tmp/dvd
gpgcheck=0
按下i进入插入模式,ESC退出插入模式,:wq保存退出
[root@localhost yum.repos.d]# yum list
[root@localhost yum.repos.d]# yum install gcc-c++
已加载插件:fastestmirror, langpacks
Loading mirror speeds from cached hostfile
软件包 gcc-c++-4.8.5-44.el7.x86_64 已安装并且是最新版本
无须任何处理
如果是备份过目录之后又重新做了一遍,可能会出现Cannot find a valid baseurl for repo: dvd这种问题,可以参考一下下面的文章请点这里
