RHEL6.5 移植使用CentOS 的YUM 步驟

標籤：http   sed   rsa   less   sig   header   軟體   system   extra   

問題：使用 Red Hat Enterprise Linux Server(RHEL) yum安裝軟體時顯示 This system is not registered with RHN. RHN support will be disabled. 

原因：

Red Hat Enterprise Linux Server(RHEL) 的yum服務是付費的，因為沒有付費，所以無法使用yum安裝軟體，如RHEL想安裝YUM，一種可行的辦法是移植使用CentOS的YUM。

解決方案：

步驟一：卸載RHEL的yum，並下載CentOS的對應軟體包

執行：rpm -qa|grep yum|xargs rpm -e --nodeps  將yum卸載掉

cat /etc/issue && uname -a 看一下系統版本號碼和系統位元

 

到 http://mirrors.kernel.org/centos/ 或 http://mirrors.163.com/centos/ 找對應系統版本號碼

 

如果系統是5.* 64位，則開啟http://mirrors.kernel.org/centos/5/os/x86_64/CentOS/
如果系統是5.* 32位，則開啟http://mirrors.kernel.org/centos/5/os/i386/CentOS/
如果系統是6.* 64位：http://mirrors.kernel.org/centos/6/os/x86_64/Packages/
如果系統是6.* 32位：http://mirrors.kernel.org/centos/6/os/i386/Packages/

 

下載的檔案包括：

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

python-urlgrabber-3.9.1-11.el6.noarch.rpm

yum-3.2.29-73.el6.centos.noarch.rpm

yum-metadata-parser-1.1.2-16.el6.i686.rpm

yum-plugin-fastestmirror-1.1.30-37.el6.noarch.rpm

 

步驟二：安裝CentOS的對應軟體包

安裝步驟：

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 python-urlgrabber-3.9.1-11.el6.noarch.rpm 

 

這一步可能出如下錯誤

warning: python-urlgrabber-3.9.1-11.el6.noarch.rpm: Header V3 RSA/SHA1Signature, key ID c105b9de: NOKEY

原因是包衝突，需要卸載原有的urlgrabber包：

[[email protected]]# rpm -qa |grep urlgrabber

python-urlgrabber-3.9.1-8.el6.noarch

 

[[email protected]]# rpm -e python-urlgrabber-3.9.1-8.el6.noarch

然後再安裝。

 

然後安裝yum

rpm -ivh yum-3.2.29-73.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-37.el6.noarch.rpm 

 

 

步驟三：產生yum.repos.d檔案

到http://mirrors.163.com的 centos協助文檔 中下載CentOS6-Base-163.repo檔案，存放到/etc/yum.repos.d中

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

改名為：CentOS6-Base.repo

 

然後把檔案裡的$releasever都改為你的Linux版本（6或者5），也就是檔案修改成如下即可：

# CentOS-Base.repo

#

# The mirror systemuses the connecting IP address of the client and the

# update status ofeach mirror to pick mirrors that are updated to and

# geographicallyclose to the client.  You should use this for CentOS updates

# unless you aremanually picking other mirrors.

#

# If themirrorlist= does not work for you, as a fall back you can try the

# remarked outbaseurl= line instead.

#

步驟四：重建緩衝

yum clean all 清除原有緩衝

yummakecache  擷取yum列表

等待，大約三分鐘後出現下面提示，表示yum更改完成：
