本文介绍了LINUX学习：关于RedHat Linux无法使用yum命令安装gcc-c++问题，希望对您有用。如果有疑问，可以联系我们。
初入职场,在给RedHat Linux安装情况的时候遇到这么个问题.
参考：
[root@localhost ~]# yum -y install gcc
Loaded plugins: katello, product-id, security, subscription-manager
Updating certificate-based repositories.
Unable to read consumer identity
Setting up Install Process
No package gcc available.
Nothing to do
对于习惯使用CentOS的人来说,不克不及使用这个命令,简直是种折磨
办理过程:
1.给linux redhat安装Centos镜像
[root@localhost~]# wget http://mirrors.163.com/.help/CentOS6-Base-163.repo
--2015-10-09 14:33:10-- http://mirrors.163.com/.help/CentOS6-Base-163.repo
Resolving mirrors.163.com... 123.58.173.186,123.58.173.185
Connecting to mirrors.163.com|123.58.173.186|:80...connected.

2015-10-09 14:33:22 (108 MB/s) -`CentOS6-Base-163.repo' saved [2341/2341]
2.改动repo文件
[root@localhost~]# mv CentOS6-Base-163.repo /etc/yum.repos.d/
淫乱 把$releasever替换成6
[root@localhost yum.repos.d]# sed -i 's#$releasever#6#g' ./CentOS6-Base-163.repo
3.肃清所有缓存
[root@localhost yum.repos.d]# yum clean all
Loaded plugins: katello, product-id, security, subscription-manager
Updating certificate-based repositories.
Unable to read consumer identity
Cleaning up Everything
4.获取yum列表
[root@localhost yum.repos.d]# yum makecache
Loaded plugins: katello, product-id, security, subscription-manager
Updating certificate-based repositories.
Unable to read consumer identity

5.搜刮安装
[root@localhost ~]# yum search gcc |grep --color '^gcc'
gcc.x86_64 : Various compilers (C, C++, Objective-C, Java, ...)
gcc-c++.x86_64 : C++ support for GCC
gcc-gfortran.x86_64 : Fortran 95 support
gcc-gnat.x86_64 : Ada 95 support for GCC
gcc-java.x86_64 : Java support for GCC
gcc-objc++.x86_64 : Objective-C++ support for GCC
gcc-objc.x86_64 : Objective-C support for GCC

gcc44-c++.x86_64 : C++ support for GCC version 4.4
gcc44-gfortran.x86_64 : Fortran support for GCC 4.4
6.安装gcc
[root@localhost yum.repos.d]# yum -y install gcc
至此,gcc安装完成,而且对于其他的编译环境也可以使用yum安装了.
