关于RedHat Linux无法使用yum命令安装gcc-c++问题

初入职场，在给RedHat Linux安装环境的时候遇到这么个问题。

[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,不能使用这个命令,简直是种折磨

解决过程:

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

2.修改repo文件

[root@localhost~]# mv CentOS6-Base-163.repo /etc/yum.repos.d/

*** 把$releasever替换成6
[root@localhost yum.repos.d]# sed -i 's#$releasever#6#g' ./CentOS6-Base-163.repo

3.清除所有缓存

[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.搜索安装

[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,并且对于其他的编译环境也可以使用yum安装了。
