一、挂载本地镜像做yum源（环境：RHEL6.5 64位 VM11）
1、进入/etc/yum.repos.d目录，
[root@localhost yum.repos.d]# ls
packagekit-media.repo rhel-source.repo
备份文件：
# cp rhel-source.repo rhel-source.repo.bak
# cp packagekit-media.repo packagekit-media.repo.bak
[root@localhost yum.repos.d]# ls
packagekit-media.repo rhel-source.repo
packagekit-media.repo.bak rhel-source.repo.bak
修改.repo文件，
# vim rhel-source.repo
在末尾加上如下内容（这里注意：不要添加中文注释，否则会报错）：
[Server]
name=Red Hat Enterprise Linux Server
baseurl=file:///mnt/dcrom #本地iso的挂载路径
enabled= #可以使用yum
gpgcheck= #设置不检查gpgkey
gpgkey=file:///mnt/dcrom/RPM-GPG-KEY-RedHat-release # 配置gpgkey的路径
2、修改yumRepo.py配置文件
方法一：直接修改文件
[root@localhost yum.repos.d]# cd /usr/lib/python2./site-packages/yum
[root@localhost yum]# vim yumRepo.py
找到第802行，修改代码
802 # remote = url + '/' + relative #原代码
803 remote = "/mnt/dcrom" + '/' + relative
方法二：执行命令
# sed -i "s#remote = url +'/' + relative#remote = '/mnt/dcrom' + '/' + relative#g" /usr/lib/python2./site-packages/yum/yumRepo.py
3、在VM设置中添加镜像文件并挂载
在终端中进行如下操作：
# mkdir /mnt/dcrom
# mount /dev/cdrom1 /mnt/dcrom/
4、导入导入rpm的签名信息并清除缓存
# rpm --import /mnt/dcrom/RPM-GPG-KEY-redhat-release#yum clean all
5、测试yum(系统默认没有安装ftp):
[root@localhost yum]# yum list | grep vsftpd
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
vsftpd.x86_64 2.2.-.el6_4. @Server
[root@localhost yum]# yum install vsftpd
6、可能遇到的错误及解决方法：
错误一：进程锁定，不能清除缓存
# yum clean all
Loaded plugins: product-id, refresh-packagekit, security, subscription-manager
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
Existing lock /var/run/yum.pid: another copy is running as pid .
Another app is currently holding the yum lock; waiting for it to exit...
The other application is: PackageKit
Memory : M RSS ( MB VSZ)
Started: Sat Nov :: - : ago
State : Sleeping, pid:
解决方法：
# kill - 2267
# yum clean all
错误二：yum损坏
# yum clean

解决方法：卸载yum,并重新安装
# rpm -qa|grep yum #查询yum有关的包
# rpm -e yum-utils #类似用"rpm -e 包的名字"方式卸载
然后通过挂载的镜像文件找到对应的包，”# rpm -ivh 包的名字“安装即可
错误三：字符集错误
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe4 in position 0: ordinal not in range(128)
解决方法：
#yum clean all
#rm -f /var/lib/rpm/__db*
#rpm --rebuilddb
#yum update
# vim /etc/yum.conf
找到下面一行：
plugins= #替换为plugins=
错误四：yum不能用了
# rpm -qa|grep yum

CentOS7下配置本地yum源
修改自网址：http://my.oschina.net/jast90/blog/292726#OSC_h2_4
系统：CentOS7 everything
1、挂载光盘
# mkdir /mnt/data
# mount /dev/cdrom /mnt/data/
2、创建本地仓库
# mkdir -p /yumrepo/local
# cp -rvf /mnt/data/Packages /yumrepo/local/
3、安装createrepo
# rpm -ivh createrepo-0.9.9-23.el7.noarch.rpm #在镜像文件Packages目录下
4、创建repo文件
# cd etc/yum.repos.d/
# vi myrepo.repo
添加内容如下：
[myrepo]
name=This is my repo
enabled=
gpgcheck=
baseurl=file:///mnt/data
5、假如yum group到刚刚创建的本地仓库
# createrepo -g /mnt/data/repodata/2bc0054a9f0f4cd3d2806d983edbe3d0dfc484d9f275d12be79eb67a040ba942-c7-x86_64-comps.xml /srv/my/repo/
6、测试grouplist
# yum grouplist
Loaded plugins: fastestmirror, langpacks
There is no installed groups file.
Maybe run: yum groups mark convert (see man yum)
