RedHat安裝yum+配置國內yum源解決redhat須要註冊才能更新源

YUM是Redhat Linux在線安裝更新及軟件的工具，可是這是RHEL的收費功能，若是沒有購買Redhat的服務時不能使用RHEL的更新源的，會提示註冊。 
在這種狀況下，想使用Redhat系統，還想用yum源來在線安裝軟件，有沒有辦法？ 
解決辦法:

1.卸載現有的yum

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

下載Centos的yum安裝包 
http://mirrors.163.com/centos/6/os/x86_64/Packages/ 
http://mirrors.163.com/centos/6/os/i386/Packages/

我這裏安裝的是x86_64的 
查看本身版本的方法：

cat /etc/redhat-release
uname -m

而後下載：

x86-64:

wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-3.2.29-81.el6.centos.noarch.rpm
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-41.el6.noarch.rpm
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/python-urlgrabber-3.9.1-11.el6.noarch.rpm

i386:

wget http://mirrors.163.com/centos/6/os/i386/Packages/yum-3.2.29-81.el6.centos.noarch.rpm
wget http://mirrors.163.com/centos/6/os/i386/Packages/yum-metadata-parser-1.1.2-16.el6.i686.rpm
wget http://mirrors.163.com/centos/6/os/i386/Packages/yum-plugin-fastestmirror-1.1.30-41.el6.noarch.rpm
wget http://mirrors.163.com/centos/6/os/i386/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm
wget http://mirrors.163.com/centos/6/os/i386/Packages/python-urlgrabber-3.9.1-11.el6.noarch.rpm
(這裏的地址不必定對)若是404?直接到http://mirrors.163.com/centos/6/os/上本身找就OK了

安裝yum

rpm -ivh python-iniparse-0.3.1-2.1.el6.noarch.rpm
rpm -ivh yum-metadata-parser-1.1.2-16.el6.x86_64.rpm 
rpm -ivh yum-3.2.29-81.el6.centos.noarch.rpm  yum-plugin-fastestmirror-1.1.30-41.el6.noarch.rpm
//rpm -ivh yum和yum-plugin-fastestmirror有相依性,因此要一塊兒裝

更新repo

在 /etc/yum.repos.d/下面把舊的*.repo備份一下（把文件後綴.repo改爲.bk，一來做備份，而來不刪除原來的repo文件，下載軟件的時候仍是會出問題，我認爲是仍是會去原來的repo文件挨個查找） 
開始使用了原做者的配置，後來發現裝軟件的時候仍是有問題 

[base] 
name=CentOS-6 - Base - 163.com 
baseurl=http://mirrors.163.com/centos/6/os/i386/ 
gpgcheck=1 
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6 
[updates] 
name=CentOS-6 - Updates - 163.com 
baseurl=http://mirrors.163.com/centos/6/updates/i386/ 
gpgcheck=1 
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6 
[extras] 
name=CentOS-6 - Extras - 163.com 
baseurl=http://mirrors.163.com/centos/6/extras/i386/ 
gpgcheck=1 
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6 
[centosplus] 
name=CentOS-6 - Plus - 163.com 
baseurl=http://mirrors.163.com/centos/6/centosplus/i386/ 
gpgcheck=1 
enabled=0 
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6 
[contrib] 
name=CentOS-6 - Contrib - 163.com 
baseurl=http://mirrors.163.com/centos/6/contrib/i386/ 
gpgcheck=1 
enabled=0 
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6 

後來換了一個網易的源

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

文件中releasever和releasever和basearch這兩個變量,必定要先確認這兩個環境變量是否存在,(echo一下) 
若是不存在,就要用數字6和i386替換,6是版本號（不要改成6.4）

    %s/$releasever/6/g

不然會出現錯誤： 
http://mirror.centos.org/centos/%24releasever/os/i386/repodata/repomd.xml: [Errno 14] PYCURL ERROR 22 - 「The requested URL returned error: 404」

最後一步

yum clean all 
yum makecache

(其實最後在yum安裝Heartbeat3.0的時候仍是安裝出錯，應該是源的問題)
