centosredhat安装yum源

废话几句： Red Hat的yum在线更新是收费的，未注册则不能使用，这个是要填序列号激活的，解决办法是更换为centos的yum。

查询原有的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

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

查询原有yum配置 [root@orcl ~]# whereis yum yum: /etc/yum [root@orcl ~]# rm -fr /etc/yum

下载需要的安装包 http://mirrors.163.com/centos/6.8/os/i386/Packages/ 系统为32的，所以我选择i386。64的自行查找x86_64。可以使用 wget http://mirrors.163.com/centos/6.8/os/i386/Packages/yum-3.2.29-73.el6.centos.noarch.rpm 下载 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

安装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 当前安装版本与服务器不兼容，退后一个版本再试。查看当前发行版本号 cat /etc/issue

重新下载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 ~]# 注意最后两个包必需同时安装，否则会相互依赖

更改yum源（使用网易的CentOS镜像源） [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 将所有 $releasever 修改为具体的版本号，我这里写的是6.8，这个自己打开（http://mirrors.163.com/centos）找一下就可以。

清理yum缓存 yum clean all

显示已安程序包及可安程序包 yum list

可以按要求更新程序包或安装 yum update / yum install 包名

到此结束了，亲们。
