redhat下yum源的配置

由於Redhat的yum在線更新是收費的，如果沒有註冊的話是不能使用的，即不能在線安裝軟件。我們可以藉助於centos系統開源包來給我們的yum工具做相應配置就可以使用了。

1、刪除redhat原有的yum源

#rpm -aq | grep yum|xargs rpm -e --nodeps

2、下載新的yum安裝包

　　這裏我們使用CentOS的yum源

從網絡下載一個文件並保存在當前目錄

#wgethttp://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、安裝yum軟件包

#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：最後兩個安裝包要放在一起同時安裝，否則會提示相互依賴，安裝失敗。

4、更改yum源 #我們使用網易的CentOS鏡像源

#cd /etc/yum.repos.d/

#wget http://mirrors.163.com/.help/CentOS6-Base-163.repo

#vi CentOS6-Base-163.repo

編輯文件，把文件裏面的$releasever全部替換爲版本號，即6 最後保存！或者直接把下面的內存拷貝到CentOS6-Base-163.repo文件中即可（已經修改好）

:%s/$releasever/6/g

#CentOS-Base.repo

#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 CentOSupdates

#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緩存

#yum clean all

#yum makecache #將服務器上的軟件包信息緩存到本地,以提高搜索安裝軟件的速度

#yum install vim* #測試域名是否可用

　　至此，Redhat6可以使用CentOS的yum源在線安裝軟件了！

本地yum源配置
1、掛載iso文件
#mount -t iso9660 /dev/cdrom /mnt/iso/

注：也可自己創建個目錄把光盤上的rpm包cp到自己建的目錄下。關於createrepo -p 自己建的目錄,然後ls *repo*查看該目錄下生成的文件，createrepo --update 自己建的目錄（如果有新rpm包扔進來需要更新）。前提是需要一個工具createrepo，使用yum安裝：yum -y install createrepo，此爲場外話

2、修改yum配置文件
#vi /etc/yum.repo.d/iso
===============
[base]
name=locale
baseurl=file:///mnt/iso/Server
enabled=1 ---開啓本地更新模式
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、清理緩存
#yum clean all
