為了搞學習核心編譯,需要安裝一些開發工具包,索性把CD光牒鏡像設定成本地yum源,這樣更快些!以下是一些基本步驟:
1、首先挂載CD光牒到/mnt/cd下,mount /dev/cdrom /mnt/cd,這個就不多說了;
2、 進入/etc/yum.repos.d/目錄下,把原來的yum源備份,我給它重新命名了。
mv CentOS-Vault.repo CentOS-Vault.repo.bak
mv CentOS-Debuginfo.repo CentOS-Debuginfo.repo.bak
mv CentOS-Base.repo CentOS-Base.repo.bak
3、建立一個CD光牒源
vim CentOS-Media.repo
# CentOS-Media.repo
#
# This repo can be used with mounted DVD media, verify the mount point for
# CentOS-6. You can use this repo and yum to install items directly off the
# DVD ISO that we release.
# To use this repo, put in your DVD and use it with the other repos too:
# yum --enablerepo=c6-media [command]
#
# or for ONLY the media repo, do this:
# yum --disablerepo=\* --enablerepo=c6-media [command]
[c6-media]
name=CentOS-$releasever - Media
baseurl=file:///mnt/cd
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
儲存退出
4、yum clean all(清除緩存)
5、yum makecache (建立新緩存)
