这类问题归根到底就是软件源问题，Linux下安装软件不像windows。Linux软件管理知识参考：https://www.cnblogs.com/kelamoyujuzhen/category/1283689.htmlnode
问题描述python
RedHat Enterprise Linux 6.4，64位。使用yum命令安装软件时候出现如下错误：linux
This system is not registered to Red Hat Subscription Management.You can use subscription-manager to register.windows
缘由centos
使用redhat的yum源是须要注册付费的。缓存
解决办法less
卸载原有yum包，替换centos 6.4的yum包ide
卸载yum包测试
rpm -aq|grep yum|xargs rpm -e --nodeps
下载centos6.4的yum包，下载路径http://vault.centos.org/6.4/os/x86_64/Packages/
依次执行
rpm -ivh yum-metadata-parser-1.1.2-16.el6.x86_64.rpm rpm -ivh yum-3.2.29-40.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm python-urlgrabber-3.9.1-8.el6.noarch.rpm
更换yum源，使用163的源
打开http://mirrors.163.com/.help/centos.html，在里面下载对应版本的repo文件，好比我下载的是CentOS6-Base-163.repo文件，而后把它放到/etc/yum.repos.d/下。还须要打开CentOS6-Base-163.repo文件修改$releasever为版本号6。
# 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.

清除原有缓存
使用命令 yum clean all 清除原来的缓存。
从新创建缓存
使用命令 yum makecache 重建缓存。
测试安装一个man，成功
yum install man -y
下面介绍方法二：
将ISO插入到虚拟机光驱
在/mnt下面建立目录cdrom，权限默认的就行。
将虚拟机光驱里面的光盘挂载到刚刚建立的目录
mount /dev/cdrom /mnt/cdrom/
查看挂载后的文件

以安装traceroute为例
在/mnt/cdrom/Packages目录下搜索
[root@51cto Packages]# pwd /mnt/cdrom/Packages [root@51cto Packages]# find -name "*traceroute*" ./traceroute-2.0.14-2.el6.x86_64.rpm
找到traceroute对应的rpm包
[root@51cto Packages]# rpm -i traceroute-2.0.14-2.el6.x86_64.rpm warning: traceroute-2.0.14-2.el6.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID fd431d51: NOKEY
如今traceroute命令就能够使用了
下面介绍方法三：
与方法一相似，只不过不是替换yum元配置文件而是修改yum源配置文件。Redhat最小化安装后/etc/yum.repos.d目录下默认配置文件rhel-source.repo。这里面指向的都是Redhat的yum源站点，咱们能够指向本地。先把/dev/cdrom挂载到/mnt/cdrom
而后rhel-source.repo文件中加上几句话
[rhel-source-local] name=Red Hat Enterprise Linux $releasever Beta - $basearch - Source baseurl=file:///mnt/cdrom/Server enabled=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-beta,file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
enabled=1 表示启用yum源
gpgcheck=1 检查数字签名，须要Redhat的公钥
gpgkey=XXXX 指定公钥位置
