在一个新的Linux服务器上安装nginx的时候，命令都不能解析，缺少gcc编辑器，安装gcc的命令也出错。
[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
没有gcc的软件包的，
最终找到一个解决办法
检查版本：
[root@localhost ~]# cat /etc/issue
Red Hat Enterprise Linux Server release 5.7 (Tikanga)
Kernel \r on an \m
解决过程：
1.下载163安装源
[root@localhost~]# wget http://mirrors.163.com/.help/CentOS5-Base-163.repo
---- ::-- http://mirrors.163.com/.help/CentOS5-Base-163.repo

2.修改repo文件(根据红帽版本)
[root@localhost~]# mv CentOS5-Base-.repo /etc/yum.repos.d/
*** 把$releasever替换成5 （红帽6版本以上的改为6）
[root@localhost yum.repos.d]# sed -i 's#$releasever#5#g' ./CentOS5-Base-.repo
3.清除原有缓存
[root@localhost yum.repos.d]# yum clean all
Loaded plugins: katello, product-id, security, subscription-manager
Updating certificate-based repositories.

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.

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 support
gcc-gnat.x86_64 : Ada 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.x86_64 : GNU Compiler Collection version 4.4
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。
但是当我安装pcre-8.39 执行./configure的时候出现错误
configure: error: You need a C++ compiler for C++ support
解决办法：
yum install -y gcc gcc-c++
