linux基础——在redhat6下配置yum源的使用
转自 http://blog.itpub.net/23890223/viewspace-757724/
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:
由于Redhat的yum在线更新是收费的,如果没有注册的话是不能使用的,即不能在线安装软件。在这种情况下,想使用Redhat系统,还想用yum源来在线安装软件,有没有办法?
答案是有办法,请往下看!
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/6.5/os/i386/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm
# wget http://mirror.centos.org/centos/6.5/os/i386/Packages/yum-metadata-parser-1.1.2-16.el6.i686.rpm
# wget http://mirror.centos.org/centos/6.5/os/i386/Packages/yum-3.2.29-40.el6.centos.noarch.rpm
# wget http://mirror.centos.org/centos/6.5/os/i386/Packages/yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm
3、安装yum软件包
# rpm -ivh python-iniparse-0.3.1-2.1.el6.noarch.rpm
# rpm -ivh yum-metadata-parser-1.1.2-14.1.el6.i686.rpm
# rpm -ivh yum-3.2.27-14.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.26-11.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/
# wget http://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
# yum install vim* #测试域名是否可用
至此,Redhat6可以使用CentOS的yum源在线安装软件了!
二、本地yum源配置
1、挂载iso文件
#mount -t iso9660 /dev/cdrom /mnt/iso/
2、修改yum配置文件
#vi /etc/yum.repo.d/iso
===============
[base]
name=locale
baseurl=file:///mnt/iso/Server
enabled=1 ---开启本地更新模式
gpgcheck=1
===============
redhat-6
====================================
[Server]
name=Server
baseurl=file:///mnt/cdrom/Server
enabled=1
gpgcheck=0
[HighAvailability]
name=HighAvailability
baseurl=file:///mnt/cdrom/HighAvailability
enabled=1
gpgcheck=0
[LoadBalancer]
name=LoadBalancer
baseurl=file:///mnt/cdrom/LoadBalancer
enabled=1
gpgcheck=0
[LoadBalancer]
name=LoadBalancer
baseurl=file:///mnt/cdrom/LoadBalancer
enabled=1
gpgcheck=0
3、清理缓存
#yum clean all
注意:报错处理
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*
