直接挂载镜像安装

首先加载radhat安装光盘，然后mount到本地

[root@localhost ~]# mount /dev/cdrom /mnt/cdradhat/
#进入安装包目录
[root@localhost Packages]# cd /mnt/cdradhat/Packages/
#安装tcpdump
[root@localhost Packages]# rpm -ivh tcpdump-4.0.0-3.20090921gitdf3cb4.2.el6.x86_64.rpm

linux radhat6.6下手动安装tcpdump

安装GCC

    #首先加载radhat安装光盘，然后mount到本地
    [root@localhost ~]# mount /dev/cdrom /mnt/cdradhat/
    #进入安装包目录
    [root@localhost Packages]# cd /mnt/cdradhat/Packages/
    #安装几个依赖包
    [root@localhost Packages]# rpm -ivh kernel-headers-2.6.32-504.el6.x86_64.rpm
    [root@localhost Packages]# rpm -ivh glibc-headers-2.12-1.149.el6.x86_64.rpm
    [root@localhost Packages]# rpm -ivh glibc-devel-2.12-1.149.el6.x86_64.rpm
    [root@localhost Packages]# rpm -ivh ppl-0.10.2-11.el6.x86_64.rpm
    [root@localhost Packages]# rpm -ivh cloog-ppl-0.15.7-1.2.el6.x86_64.rpm
    [root@localhost Packages]# rpm -ivh mpfr-2.4.1-6.el6.x86_64.rpm
    [root@localhost Packages]# rpm -ivh cpp-4.4.7-11.el6.x86_64.rpm
    [root@localhost Packages]# rpm -ivh gcc-4.4.7-11.el6.x86_64.rpm

表示GCC安装成功
