初入职场,给linux redhat安装环境的时候,遇到这么个问题

[root@localhost ~]# yum -y install gccLoaded plugins: katello, product-id, security, subscription-managerUpdating certificate-based repositories.Unable to read consumer identitySetting up Install ProcessNo 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.repoResolving mirrors.163.com... 123.58.173.186,123.58.173.185Connecting to mirrors.163.com|123.58.173.186|:80...connected.HTTP request sent, awaiting response... 200 OKLength: 2341 (2.3K) [application/octet-stream]Saving to: `CentOS6-Base-163.repo'100%2,341    --.-K/s  in 0s   2015-10-09 14:33:22 (108 MB/s) -`CentOS6-Base-163.repo' saved [2341/2341]

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 allLoaded plugins: katello, product-id, security, subscription-managerUpdating certificate-based repositories.Unable to read consumer identityCleaning up Everything

4.获取yum列表

[root@localhost yum.repos.d]# yum makecacheLoaded plugins: katello, product-id, security, subscription-managerUpdating certificate-based repositories.Unable to read consumer identityaddons                                                 | 1.9 kB   00:00   addons/filelists_db                                          | 570 B   00:00   ................base                                                        3667/3667base                                                        3667/3667base                                                        3667/3667Metadata Cache Created

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 GCCgcc-gfortran.x86_64 : Fortran 95 supportgcc-gnat.x86_64 : Ada 95 support for GCCgcc-java.x86_64 : Java support for GCCgcc-objc++.x86_64 : Objective-C++ support for GCCgcc-objc.x86_64 : Objective-C support for GCCgcc44.x86_64 : GNU Compiler Collection version 4.4gcc44-c++.x86_64 : C++ support for GCC version 4.4gcc44-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
