centos中yum采用光盘为软件安装源
在某些环境下不能访问外网,这时采用完全版光盘为安装源也是一个选择,
环境:CentOS release 5.5 (Final)
1,挂载系统盘(DVD版CentOS-5.5-i386-bin-DVD.iso)光驱:
mkdir /media/cdrom mount /dev/cdrom /media/cdrom
2,保留安装库文件:
/etc/yum.repos.d/CentOS-Media.repo
# CentOS-Media.repo # # This repo is used to mount the default locations for a CDROM / DVD on # CentOS-5. 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=c5-media [command] # # or for ONLY the media repo, do this: # # yum --disablerepo=\* --enablerepo=c5-media [command] [c5-media] name=CentOS-$releasever - Media baseurl=file:///media/cdrom/ gpgcheck=1 enabled=0 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5
3,测试yum安装源:
[root@localhost cdrom]# yum --enablerepo=c5-media info vsftpd Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile Installed Packages Name : vsftpd Arch : i386 Version : 2.0.5 Release : 16.el5_4.1 Size : 285 k Repo : installed Summary : vsftpd - 非常安全 Ftp 守护进程 URL : http://vsftpd.beasts.org/ License : GPL Description: vsftpd 是一个非常安全 FTP 守护进程。它是完全从零开始 : 编写的。
4,常用yum命令:
删除CentOS5的图形界面软件包:
yum --enablerepo=c5-media --disableplugin=fastestmirror groupremove "GNOME Desktop Environment"
yum --enablerepo=c5-media --disableplugin=fastestmirror groupremove "X Window System"
安装中文环境语言相关包:
yum --enablerepo=c5-media --disableplugin=fastestmirror groupinstall "chinese-support"
