由于Redhat的yum在線更新是收費(fèi)的，如果沒有注冊(cè)的話是不能使用的，即不能在線安裝軟件。所以yum install 命令每次都安裝失敗

下面介紹一種更改yum源的方式：

系統(tǒng)說明：

系統(tǒng)：Red Hat Enterprise Linux Server 6.3

內(nèi)核：Linux 2.6.32-279.el6.x86_64

1、刪除RHEL原有的yum
?? ? rpm -aq|grep yum|xargs rpm -e --nodeps? #刪除

?

2、下載新的yum安裝包? #這里我們使用CentOS的yum源
?????? 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/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm

wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-3.2.29-60.el6.centos.noarch.rpm?

wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-30.el6.noarch.rpm

?(提示：如果下載時(shí)提示404找不到錯(cuò)誤，請(qǐng)?jiān)L問http://mirrors.163.com/centos/6/os/x86_64/Packages/，手動(dòng)查找上面四個(gè)包，有時(shí)候版本會(huì)有點(diǎn)小偏差)

3、安裝yum軟件包

rpm -ivh? python-iniparse-0.3.1-2.1.el6.noarch.rpm

rpm -ivh? yum-metadata-parser-1.1.2-16.el6.x86_64.rpm

rpm -ivh ?yum-3.2.29-60.el6.centos.noarch.rpm???yum-plugin-fastestmirror-1.1.30-30.el6.noarch.rpm

?? ? (這里要注意的是：最后兩個(gè)安裝包要放在一起同時(shí)安裝，否則會(huì)提示相互依賴，安裝失敗。)

4、更改yum源? #我們使用網(wǎng)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

把文件里面的$releasever全部替換為版本號(hào)，即6 最后保存！

?

或者直接把下面的內(nèi)存拷貝到CentOS6-Base-163.repo文件中即可

（已經(jīng)修改好，不用下載直接新建CentOS6-Base-163.repo 也???? 可以）

?

# 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 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、收尾，測(cè)試YUM 是否可用

yum clean all???? #清理yum緩存

yum makecache???? #將服務(wù)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(cè)試yum是否可用
