redhat6.9 安装yum
redhat6.9 使用yum安装出现如下问题：
[root@redhat6 ~]# yum install -y gcc gcc-c++
已加载插件：product-id, refresh-packagekit, search-disabled-repos, security, subscription-manager
This system is not registered with an entitlement server. You can use subscription-manager to register.
设置安装进程
No package gcc available.
No package gcc-c++ available.
错误：无须任何处理
原因： 此系统没有注册到授权服务器。您可以使用订阅管理器进行注册。
Red Hat Enterprise Linux Server(RHEL) 的yum服务是付费的，因为没有付费，所以无法使用yum安装软件。
解决办法：
1.查看该系统版本：
[root@redhat6 ~]# cat /etc/issue&& uname -a
Red Hat Enterprise Linux Server release 6.9 (Santiago)
Kernel \r on an \m
Linux redhat6.9 2.6.32-696.el6.x86_64 #1 SMP Tue Feb 21 00:53:17 EST 2017 x86_64 x86_64 x86_64 GNU/Linux
2. 查看自带的yum安装包 并删除
[root@redhat6 ~]# rpm -qa|grep yum
yum-rhn-plugin-0.9.1-60.2.el6_8.noarch
yum-3.2.29-81.el6.noarch
PackageKit-yum-plugin-0.5.8-26.el6.x86_64
yum-utils-1.1.30-40.el6.noarch
yum-plugin-security-1.1.30-40.el6.noarch
PackageKit-yum-0.5.8-26.el6.x86_64
yum-metadata-parser-1.1.2-16.el6.x86_64
[root@redhat6 yumdir]# rpm -qa|grep yum|xargs rpm -e --nodeps
[root@redhat6 yumdir]# rpm -qa|grep yum
3. 安装yum
[root@redhat6 yao]# cd yumdir/
[root@redhat6 yumdir]# pwd
/root/yao/yumdir
[root@redhat6 yumdir]# wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yumarser-1.1.2-16.el6.x86_64.rpm
[root@redhat6 yumdir]# wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-3.2.29-81.el6.centos.noarch.rpm
[root@redhat6 yumdir]#
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-41.el6.noarch.rpm
[root@redhat6 yumdir]# ls
yum-3.2.29-81.el6.centos.noarch.rpm
yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
yum-plugin-fastestmirror-1.1.30-41.el6.noarch.rpm
[root@redhat6 yumdir]# rpm -ivh yum-*

[root@redhat6 yumdir]# rpm -qa|grep yum
yum-metadata-parser-1.1.2-16.el6.x86_64
yum-3.2.29-81.el6.centos.noarch
yum-plugin-fastestmirror-1.1.30-41.el6.noarch
[root@redhat6 yumdir]# cd /etc/yum.repos.d/
[root@redhat6 yum.repos.d]# ls
local.repo redhat.repo rhel-source.repo
[root@redhat6 yum.repos.d]# wget http://mirrors.163.com/.help/CentOS6-Base-163.repo
[root@redhat6 yum.repos.d]# vim CentOS6-Base-163.repo
将该文件中的所有 $releaserver 修改为 相应的系统版本 。例如我的版本号为 “6 ”
不然会出现如下错误：
Cannot retrieve repository metadata (repomd.xml) for repository: base. Please verify its path and try again
[root@redhat6 yum.repos.d]# yum clean all
[root@redhat6 yum.repos.d]# yum makecache
更新yum
[root@redhat6 yum.repos.d]# yum -update -y

[root@redhat7 yumdir]# rpm -ivh yum-*
出现问题如下：

[root@redhat7 yumdir]# rpm -ivh yum-* --force --nodeps
继续安装：
[root@redhat7 yum.repos.d]# wget http://mirrors.163.com/.help/CentOS7-Base-163.repo
[root@redhat7 yum.repos.d]# vim CentOS7-Base-163.repo
将该文件中的所有 $releaserver 修改为 相应的系统版本 。例如我的版本号为 “7”
[root@redhat6 yum.repos.d]# yum clean all
[root@redhat6 yum.repos.d]# yum makecache
更新yum
[root@redhat6 yum.repos.d]# yum -update -y
测试 使用： yum install -y gcc gcc-c++
现实安装成功
