redhat6.x配置使用163源
新安装了redhat6安装后，登录系统，使用yum update 更新系统。提示：
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
无法更新。
redhat 默认自带的 yum 源需要注册，才能更新。我们想不花钱也可以更新，需要替换掉redhat的yum源。
1.检查是否安装yum包
查看RHEL是否安装了yum，若是安装了，那么又有哪些yum包：
[root@localhost ~]# rpm -qa |grep yum
yum-metadata-parser-1.0-8.fc6
yum-3.0.1-5.el5
yum-rhn-plugin-0.4.3-1.el5
yum-updatesd-3.0.1-5.el5
2 删除redhat自带的yum包
卸载上面显示的所有yum包：
[root@localhost ~]# rpm -qa|grep yum|xargs rpm -e --nodeps（不检查依赖，直接删除rpm包）
再用
[root@localhost ~]# rpm -qa |grep yum
[root@localhost ~]#
查看，无信息显示表示已经卸载完成。
3.下载新的yum包。使用Centos6.x的yum包:
登入：http://mirrors.163.com/centos/6/os/x86_64/Packages/，下载以下包的最新版本：
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
安装以上包：
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 python-urlgrabber-3.9.1-11.el6.noarch.rpm yum-3.2.29-81.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-40.el6.noarch.rpm --force
4.更换yum源。使用163的源
1 2 3 | # cd /etc/yum.repos.d/# wget http://mirrors.163.com/.help/CentOS6-Base-163.repo# vi CentOS6-Base-163.repo |
编辑文件，如把文件里面的$releasever全部替换为版本号，即6.5最后保存！或者直接把下面的内存拷贝到CentOS6-Base-163.repo文件中即可（已经修改好）
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 |

5.清除原有缓存
1 | # yum clean all |
重建缓存，以提高搜索安装软件的速度
1 | # yum makecache |
6.更新系统
1 | # yum update |
