Red Hat Linux安裝CentOS的yum源

導讀	RedHat憑藉其卓越的穩定性和強大的服務佔領着企業linux大部分市場，系統自己免費，可是其服務倒是收費的，例如其軟件包管理服務yum。不想出錢那就本身配置yum源就行了，由於yum在線更新是收費的，未註冊則不能使用，這個是要填序列號激活的，解決辦法是更換爲CentOS的yum。

設置步驟

1. 查詢原有的yum

[root@orcl ~]# rpm -qa |grep yum 
yum-plugin-fastestmirror-1.1.30-37.el6.noarch 
yum-metadata-parser-1.1.2-16.el6.i686 
yum-utils-1.1.30-37.el6.noarch 
yum-plugin-security-1.1.30-37.el6.noarch 
yum-3.2.29-75.el6.centos.noarch 
yum-rhn-plugin-0.9.1-43.el6.noarch

2. 刪除原有的yum

[root@orcl ~]# rpm -aq|grep yum|xargs rpm -e –nodeps 
[root@orcl ~]# rpm -qa |grep yum 
[root@orcl ~]#

3. 查詢原有yum配置

[root@orcl ~]# whereis yum 
yum: /etc/yum 
[root@orcl ~]# rm -fr /etc/yum

4. 下載須要的安裝包
http://mirrors.163.com/centos/6.8/os/i386/Packages/
系統爲32的，因此我選擇i386。64的自行查找x86_64。
能夠使用

wget http://mirrors.163.com/centos/6.8/os/i386/Packages/yum-3.2.29-73.el6.centos.noarch.rpm

下載

yum-3.2.29-73.el6.centos.noarch.rpm 
yum-plugin-fastestmirror-1.1.30-37.el6.noarch.rpm 
yum-metadata-parser-1.1.2-16.el6.i686.rpm 
Python-iniparse-0.3.1-2.1.el6.noarch.rpm

5. 安裝python

[root@orcl ~]# rpm -ivh python-iniparse-….noarch.rpm 
warning: python-iniparse-0.4-9.el7.noarch.rpm: Header V3 RSA/SHA256 Signature, key ID f4a80eb5: NOKEY 
error: Failed dependencies: 
python(abi) = 2.7 is needed by python-iniparse-0.4-9.el7.noarch

當前安裝版本與服務器不兼容，退後一個版本再試。
查看當前發行版本號

cat /etc/issue

 

遇到的錯誤

系統位數與安裝程序包位數不一致 file /bin/ls

error: Failed dependencies:

從新下載32位程序包

[root@orcl ~]# rpm -ivh python-iniparse-0.3.1-2.1.el6.noarch.rpm 
Preparing… ########################################### [100%] 
package python-iniparse-0.3.1-2.1.el6.noarch is already installed 
[root@orcl ~]# rpm -ivh yum-metadata-parser-1.1.2-16.el6.i686.rpm 
Preparing… ########################################### [100%] 
1:yum-metadata-parser ########################################### [100%] 
[root@orcl ~]# rpm -ivh yum-3.2.29-73.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-37.el6.noarch.rpm 
Preparing… ########################################### [100%] 
1:yum-plugin-fastestmirro########################################### [ 50%] 
2:yum ########################################### [100%] 
[root@orcl ~]#

注意最後兩個包必需同時安裝，不然會相互依賴
更改yum源（使用網易的CentOS鏡像源）

[root@localhost yum]# cd /etc/yum.repos.d/ 
[root@localhost yum.repos.d]# rm -rf * 
[root@localhost yum.repos.d]# wget http://mirrors.163.com/.help/CentOS6-Base-163.repo 
[root@localhost yum.repos.d]# vi CentOS6-Base-163.repo

將全部 $releasever 修改成具體的版本號，我這裏寫的是6.8，這個本身打開（http://mirrors.163.com/centos）找一下就能夠。

# 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.

清理yum緩存

yum clean all

顯示已安程序包及可安程序包

yum list

能夠按要求更新程序包或安裝

yum update / yum install 包名

到此結束了，親們
