centos5.4安装gcc

不能上网，利用光盘安装 gcc 和 gcc-c++的方法如下：

首先把光盘放入光驱内，虚拟机内的话就用 iso 光盘镜像就可以了。

然后如下：

[root@localhost ~]# more gcc_install.sh

#!/bin/bash
mount /dev/cdrom /mnt
cd /mnt/CentOS/
rpm -ivh glibc-common-2.5-42.i386.rpm
rpm -ivh kernel-headers-2.6.18-164.el5.i386.rpm
rpm -ivh libgcc-4.1.2-46.el5.i386.rpm
rpm -ivh glibc-2.5-42.i686.rpm
rpm -ivh cpp-4.1.2-46.el5.i386.rpm
rpm -ivh libgomp-4.4.0-6.el5.i386.rpm
rpm -ivh nscd-2.5-42.i386.rpm
rpm -ivh glibc-headers-2.5-42.i386.rpm
rpm -ivh glibc-devel-2.5-42.i386.rpm
rpm -ivh gcc-4.1.2-46.el5.i386.rpm
echo "gcc is installed successful!!!"
rpm -ivh libstdc++-4.1.2-46.el5.i386.rpm
rpm -ivh libstdc++-devel-4.1.2-46.el5.i386.rpm
rpm -ivh gcc-c++-4.1.2-46.el5.i386.rpm
echo "gcc-c++ is installed successful!!!"

[root@localhost ~]# chmod +x gcc_install.sh

[root@localhost ~]# ./gcc_install.sh

这样就成功了，注意我这里用的是CentOS 5.4， 假如你用的CentOS是其他版本的话，就得上光盘中看看，rpm包的名字改变了没有，注意其实也是是版本号发生了变化。。。
