每次用rpm包安装软件是总有依赖包的出现，今天我搭建了本地yum仓库，使用yum从光盘安装软件可以解决包的依赖关系，具体操作如下:
1.挂载光盘镜像
[root@centos ~]# mkdir /mnt/cdrom
[root@centos ~]# mount /dev/cdrom /mnt/cdrom/
mount: block device /dev/sr0 is write-protected, mounting read-only
[root@centos ~]# vim /etc/yum.repos.d/CentOS-Media.repo
[c6-media]
name=CentOS-$releasever - Media --仓库名
baseurl=file:///mnt/cdrom --软件包路径
gpgcheck=1 --启用包检查
enabled=1 --启用这个仓库
gpgkey=file:///mnt/cdrom/RPM-GPG-KEY-CentOS-6
2.测试仓库
[root@centos ~]# yum clean all --清除所有包
Loaded plugins: fastestmirror, refresh-packagekit
Cleaning repos: c6-media
Cleaning up Everything
Cleaning up list of fastest mirrors
[root@centos ~]# yum repolist --查找有几个仓库
Loaded plugins: fastestmirror, refresh-packagekit
Determining fastest mirrors
c6-media | 4.0 kB 00:00 ...
c6-media/primary_db | 3.5 MB 00:00 ...
repo id repo name status
c6-media CentOS-6 - Media 4,802
repolist: 4,802
[root@centos ~]#
3.安装软件
[root@centos ~]# yum install gpm --安装软件
Loaded plugins: fastestmirror, refresh-packagekit
Loading mirror speeds from cached hostfile

4.常用yum基本命令
yum --help --帮助信息
yum list --列出软件包
yum repolist --查看有多少仓库
yum info 软件包 --软件包的信息
yum install 软件包 --安装软件包
yum update 软件包 --更新软件包
yum provides 命令 --用命令查找要安装的软件包
yum reinstall 软件包 --覆盖安装软件包
yum remove 软件包 --删除软件
yum clean 软件包 --清除软件包
yum grouplist --查看软件组
yum groupinstall "软件组" --安装软件组
yum install info "软件组" --查看软件组的信息
yum remove “组件组" --删除软件组
yum search 软件包 --检测是否有软件包
yum install * --nogpgcheck --跳过KEY安装软件包
