Redhat通过yum安装配置gcc_red hat11g使用yum install gcc 命令,为你的系统安装gcc工具。

说明：最近有个项目，客户要求服务器使用redhat，为了安全起见，自己要先演练演练看看有没有什么问题。公司网管装了虚拟机，拿到手装软件的时候发现make的时候报错，归因gcc工具没有。没有就安装咯。因为虚拟机不能直接上外网，申请开通上外网处理流程也麻烦，刚开始的想法是下载rpm安装。七搞八搞，废了九牛二虎之力，最终也没有搞好，原因包依赖太多，很多包下载源也找不到。

还是回到yum安装这条路上，不过RedHat 没有注册，使用yum install gcc的时候会出现This system is not registered with RHN；网上查了下可以通过更换源来进行相关更新：更改yum的源，即更换文件/etc/yum.repos.d/rhel-source.repo；网上其他文章说是rhel-debuginfo.repo，不过我的系统上只有rhel-source.repo，替换之后确实管用。

操作系统版本：

cat /etc/issue
Red Hat Enterprise Linux Server release 6.3 (Santiago)
Kernel \r on an \m

操作步骤：

步骤1：进入/etc/yum.repos.d/目录

cd /etc/yum.repos.d/

步骤2：终端输入以下命令，获取CentOS-Base.repo

wget http://mirrors.163.com/.help/CentOS6-base-163.repo

步骤3：切换到/etc/yum.repos.d目录，备份以前的repo文件，

cp rhel-source.repo rhel-source.repo.bak

步骤4：将CentOS-Base.repo改名为redhat的repo

mv CentOS-Base.repo rhel-source.repo

步骤5：因为网上已经不再6.7以前的版本提供了，因此将文件中的变量“$releaserver”替换为6.7，使用CentOS6.7文件

可以用vi工具编辑，也可以下载到pc上改完后再传上去，处理后文件如下

# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.

好了，直接yum可以正常使用了，执行 yum -y install gcc即可完成安装。

yum -y install gcc
