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 --2015-10-09 14:33:10-- http://mirrors.163.com/.help/CentOS5-Base-163.repo Resolving mirrors.163.com... 123.58.173.186,123.58.173.185 Connecting to mirrors.163.com|123.58.173.186|:80...connected. HTTP request sent, awaiting response... 200 OK Length: 2341 (2.3K) [application/octet-stream] Saving to: `CentOS5-Base-163.repo' 100%2,341 --.-K/s in 0s 2015-10-09 14:33:22 (108 MB/s) -`CentOS5-Base-163.repo' saved [2341/2341]
2.修改repo文件(根据红帽版本)
[root@localhost~]# mv CentOS5-Base-163.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-163.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. 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 addons | 1.9 kB 00:00 addons/filelists_db | 570 B 00:00 addons/other_db | 554 B 00:00 addons/primary_db | 1.1 kB 00:00 base | 1.1 kB 00:00 base/filelists | 3.7 MB 00:11 base/other | 14 MB 01:04 base/group | 1.1 MB 00:03 base/primary | 1.3 MB 00:06 epel | 3.6 kB 00:00 epel/filelists_db | 4.1 MB 00:16 epel/updateinfo | 510 kB 00:02 epel/other_db | 1.6 MB 00:05 epel/primary_db | 2.9 MB 00:14 extras | 2.1 kB 00:00 extras/filelists_db | 224 kB 00:00 extras/other_db | 442 kB 00:01 extras/group | 9.7 kB 00:00 extras/primary_db | 173 kB 00:00 updates | 1.9 kB 00:00 updates/filelists_db | 2.1 MB 00:09 updates/other_db | 11 MB 00:29 updates/primary_db | 531 kB 00:00 base 3667/3667 base 3667/3667 base 3667/3667 Metadata 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 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.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++
