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
