linux7下配置yum源,在redhat6.7下配置yum源的使用
有好多朋友使用linux
redhat版本是不是还在为rpm包的安装而烦恼，yum工具的使用无意是解决这一难题的好工具，他可以解决包安装中依赖问题，但是对于redhat版本的系统来说如果想使用yum的在线安装功能是需要银子的，那有没有在redhat下不要银子就可以使用yum呢，回答是肯定的可以使用，我们可以借助于centos系统开源包来给我们的yum工具做相应配置就可以使用了。配置如下：
1、删除redhat原有的yum源
# rpm -aq | grep yum|xargs rpm -e --nodeps
2、下载新的yum安装包
这里我们使用CentOS的yum源
# wget
http://mirror.centos.org/centos/6.7/os/i386/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm
# wget
http://mirror.centos.org/centos/6.7/os/i386/Packages/yum-metadata-parser-1.1.2-16.el6.i686.rpm
#wget
http://mirror.centos.org/centos/6.7/os/i386/Packages/yum-3.2.29-69.el6.centos.noarch.rpm
# wget
http://mirror.centos.org/centos/6.7/os/i386/Packages/yum-plugin-fastestmirror-1.1.30-30.el6.noarch.rpm
3、安装yum软件包
# rpm
-ivhpython-iniparse-0.3.1-2.1.el6.noarch.rpm
# rpm
-ivhyum-metadata-parser-1.1.2-16.el6.i686.rpm
# rpm
-ivhyum-3.2.29-69.el6.centos.noarch.rpm
yum-plugin-fastestmirror-1.1.30-30.el6.noarch.rpm
注意：最后两个安装包要放在一起同时安装，否则会提示相互依赖，安装失败。
4、更改yum源#我们使用网易的CentOS镜像源
# cd /etc/yum.repos.d/
#
wgethttp://mirrors.163.com/.help/CentOS6-Base-163.repo
# vi CentOS6-Base-163.repo
编辑文件，把文件里面的$releasever全部替换为版本号，即6最后保存！或者直接把下面的内存拷贝到CentOS6-Base-163.repo文件中即可(已经修改好)
:%s/$releasever/6/g

# 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.

5、清理yum缓存
# yum clean all
# yum
makecache#将服务器上的软件包信息缓存到本地,以提高搜索安装软件的速度
二、本地yum源配置
1、挂载iso文件
#mount -t auto /dev/cdrom /mnt/cdrom
挂载光盘设备至/mnt/cdrom目录,若无目录请创建
2、修改yum配置文件
#vi
/etc/yum.repo.d/iso
修改如下内容后保存
[yum-local-source] #自定名称
name=RHEL6.7 #自定义名称
baseurl=file:///mnt/cdrom #光盘挂载路径
enabled=1 #启用该源
gpgcheck=0 #不启用GPG-KEY检查
接着执行如下命令
#yum clean all
#yum makecache
注意：报错处理
yum安装rpm包时遇到“warning: rpmts_HdrFromFdno: Header V3
DSA signature: NOKEY”的解决办法
在Redhat
Linux下用yum安装rpm时有时候会出现下面错误导致安装失败warning: rpmts_HdrFromFdno: Header V3 DSA signature: NOKEY, key ID*****
这是由于yum安装了旧版本的GPG
keys造成的，解决办法是可以运行下面命令：$ sudo rpm --import /etc/pki/rpm-gpg/RPM*
