redhat6下安装centos的yum源

因为redhat中的yum是收费的，未注册时不允许使用的，下面是挂载光盘后的情况，未挂载是没有yum命令。但是下面即便挂载了也是需要验证的

[root@localhost /]# yum install openssl
Loaded plugins: product-id, refresh-packagekit, security, subscription-manager
Updating certificate-based repositories.
Unable to read consumer identity
Setting up Install Process
Nothing to do

所以最好是去使用centos的yum源，免费的。

推文：RedHat6使用CentOS yum源 换yum

安装步骤：

一：查看原来的yum源，删除原有yum源

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

二：下载centos的yum安装包

这里使用网易的yum源即可，快些

http://mirrors.163.com/centos/6/os/x86_64/Packages/　　#修改前面的6可以修改centos版本　　注意（x86_64是64位系统，i386是32位）

安装yum源的相关依赖包

http://mirrors.163.com/centos/6/os/x86_64/Packages/python-urlgrabber-3.9.1-11.el6.noarch.rpm
http://mirrors.163.com/centos/6/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm

yum源包

http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-3.2.29-81.el6.centos.noarch.rpm
http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-40.el6.noarch.rpm
http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-updateonboot-1.1.30-40.el6.noarch.rpm
http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-utils-1.1.30-40.el6.noarch.rpm

注意：在上面yum源包中yum=metadata-parser是需要系统版本要求，需要64位，这里我们的系统是32位，会出现错误

error: Failed dependencies:
        libc.so.6()(64bit) is needed by yum-metadata-parser-1.1.2-16.el6.x86_64
        libc.so.6(GLIBC_2.2.5)(64bit) is needed by yum-metadata-parser-1.1.2-16.el6.x86_64
        libglib-2.0.so.0()(64bit) is needed by yum-metadata-parser-1.1.2-16.el6.x86_64
        libpthread.so.0()(64bit) is needed by yum-metadata-parser-1.1.2-16.el6.x86_64
        libpython2.6.so.1.0()(64bit) is needed by yum-metadata-parser-1.1.2-16.el6.x86_64

        libxml2.so.2(LIBXML2_2.4.30)(64bit) is needed by yum-metadata-parser-1.1.2-16.el6.x86_64

所以我们需要再去下载一个32位的包,原来的删掉

http://mirrors.163.com/centos/6/os/i386/Packages/yum-metadata-parser-1.1.2-16.el6.i686.rpm

[root@localhost yum]# rm -rf yum-metadata-parser-1.1.2-16.el6.x86_64.rpm 

三：上传安装包

[root@localhost yum]# ls
python-iniparse-0.3.1-2.1.el6.noarch.rpm
python-urlgrabber-3.9.1-11.el6.noarch.rpm
yum-3.2.29-81.el6.centos.noarch.rpm
yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
yum-plugin-fastestmirror-1.1.30-40.el6.noarch.rpm
yum-updateonboot-1.1.30-40.el6.noarch.rpm
yum-utils-1.1.30-40.el6.noarch.rpm

四：先安装python依赖包

[root@localhost yum]# rpm -ivh python-iniparse-0.3.1-2.1.el6.noarch.rpm 
warning: python-iniparse-0.3.1-2.1.el6.noarch.rpm: Header V3 RSA/SHA256 Signature, key ID c105b9de: NOKEY
Preparing...                ########################################### [100%]
        package python-iniparse-0.3.1-2.1.el6.noarch is already installed

[root@localhost yum]# rpm -ivh python-urlgrabber-3.9.1-11.el6.noarch.rpm 
warning: python-urlgrabber-3.9.1-11.el6.noarch.rpm: Header V3 RSA/SHA1 Signature, key ID c105b9de: NOKEY
Preparing...                ########################################### [100%]
        file /usr/lib/python2.6/site-packages/urlgrabber/grabber.py from install of python-urlgrabber-3.9.1-11.el6.noarch conflicts with file from package python-urlgrabber-3.9.1-8.el6.noarch
        file /usr/lib/python2.6/site-packages/urlgrabber/grabber.pyc from install of python-urlgrabber-3.9.1-11.el6.noarch conflicts with file from package python-urlgrabber-3.9.1-8.el6.noarch
        file /usr/lib/python2.6/site-packages/urlgrabber/grabber.pyo from install of python-urlgrabber-3.9.1-11.el6.noarch conflicts with file from package python-urlgrabber-3.9.1-8.el6.noarch
        file /usr/lib/python2.6/site-packages/urlgrabber/progress.pyc from install of python-urlgrabber-3.9.1-11.el6.noarch conflicts with file from package python-urlgrabber-3.9.1-8.el6.noarch
        file /usr/lib/python2.6/site-packages/urlgrabber/progress.pyo from install of python-urlgrabber-3.9.1-11.el6.noarch conflicts with file from package python-urlgrabber-3.9.1-8.el6.noarch

这里发现：安装python-urlgrabber与原来的python中的插件冲突（已经安装了一个低版本的，我们要先去卸载他）

[root@localhost yum]# rpm -qa|grep python-url　　查看已安装的旧版本python-urlgrabber

python-urlgrabber-3.9.1-8.el6.noarch

[root@localhost yum]# rpm -e --nodeps python-urlgrabber-3.9.1-8.el6.noarch　　#强制卸载
[root@localhost yum]# rpm -qa|grep python-url
[root@localhost yum]# 

再次去安装新的python-urlgrabber

[root@localhost yum]# rpm -ivh python-urlgrabber-3.9.1-11.el6.noarch.rpm 
warning: python-urlgrabber-3.9.1-11.el6.noarch.rpm: Header V3 RSA/SHA1 Signature, key ID c105b9de: NOKEY
Preparing...                ########################################### [100%]
   1:python-urlgrabber      ########################################### [100%]

成功！！

五：开始安装yum源

[root@localhost yum]# ls
yum-3.2.29-81.el6.centos.noarch.rpm
yum-metadata-parser-1.1.2-16.el6.i686.rpm
yum-plugin-fastestmirror-1.1.30-40.el6.noarch.rpm
yum-updateonboot-1.1.30-40.el6.noarch.rpm
yum-utils-1.1.30-40.el6.noarch.rpm

[root@localhost yum]# rpm -ivh yum-*

注意：有可能你之前有安装过其他的yum包，没有卸载干净，这时我们需要先去卸载掉原有的

[root@localhost yum]# rpm -qa| grep yum
yum-updateonboot-1.1.30-40.el6.noarch
yum-3.2.29-30.el6.noarch
yum-utils-1.1.30-14.el6.noarch
yum-rhn-plugin-0.9.1-40.el6.noarch
PackageKit-yum-0.5.8-20.el6.i686
yum-plugin-security-1.1.30-14.el6.noarch
yum-plugin-fastestmirror-1.1.30-40.el6.noarch
yum-metadata-parser-1.1.2-16.el6.i686
PackageKit-yum-plugin-0.5.8-20.el6.i686

将所有的卸载掉

[root@localhost yum]# rpm -e --nodeps yum-3.2.29-30.el6.noarch
[root@localhost yum]# rpm -e --nodeps yum-updateonboot-1.1.30-40.el6.noarch
[root@localhost yum]# rpm -e --nodeps yum-plugin-fastestmirror-1.1.30-40.el6.noarch
[root@localhost yum]# rpm -e --nodeps yum-metadata-parser-1.1.2-16.el6.i686
[root@localhost yum]# rpm -e --nodeps yum-utils-1.1.30-14.el6.noarch
[root@localhost yum]# rpm -e --nodeps yum-plugin-security-1.1.30-14.el6.noarch
[root@localhost yum]# rpm -e --nodeps PackageKit-yum-plugin-0.5.8-20.el6.i686
[root@localhost yum]# rpm -e --nodeps yum-rhn-plugin-0.9.1-40.el6.noarch

重新安装：

[root@localhost yum]# rpm -ivh yum-*
warning: yum-3.2.29-81.el6.centos.noarch.rpm: Header V3 RSA/SHA1 Signature, key ID c105b9de: NOKEY
Preparing...                ########################################### [100%]
   1:yum-metadata-parser    ########################################### [ 20%]
   2:yum-plugin-fastestmirro########################################### [ 40%]
   3:yum                    ########################################### [ 60%]
   4:yum-updateonboot       ########################################### [ 80%]
   5:yum-utils              ########################################### [100%]

安装完成！！

六：修改yum的repo配置文件

[root@localhost yum]# cd /etc/yum.repos.d/
[root@localhost yum.repos.d]# ls
epel.repo  epel-testing.repo  packagekit-media.repo  rhel-source.repo
[root@localhost yum.repos.d]# rm -rf *

下载centos的repo文件，放到上面的文件夹下

[root@localhost yum.repos.d]# wget http://mirrors.163.com/.help/CentOS6-Base-163.repo  #没有网可以直接下载，再去上传

[root@localhost yum.repos.d]# ls
CentOS6-Base-163.repo

修改配置文件：将baseurl中的$releasever修改为centos版本号，这里使用6既可以

# 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.
#
