最近在折騰RedHat，我安裝的版本是rhel-server-6.1-x86_64。RHEL 6.1默認是沒有gcc和gcc-c++環境的，而且我也沒有$購買正版服務。
只能想辦法本地安裝了，總結方法如下：
上傳安裝鏡像rhel-server-6.1-x86_64-dvd.iso，
然後將鏡像文件掛，如/mnt
# mount -o loop rhel-server-6.1-x86_64-dvd.iso /mnt
# cd /mnt/Packages
# rpm -ivh glibc-common-2.12-1.25.el6.x86_64.rpm
# rpm -ivh kernel-headers-2.6.32-131.0.15.el6.x86_64.rpm
# rpm -ivh libgcc-4.4.5-6.el6.x86_64.rpm
# rpm -ivh glibc-2.12-1.25.el6.x86_64.rpm
# rpm -ivh libgomp-4.4.5-6.el6.x86_64.rpm
# rpm -ivh nscd-2.12-1.25.el6.x86_64.rpm
# rpm -ivh glibc-headers-2.12-1.25.el6.x86_64.rpm
# rpm -ivh glibc-devel-2.12-1.25.el6.x86_64.rpm
# rpm -ivh mpfr-2.4.1-6.el6.x86_64.rpm
# rpm -ivh ppl-0.10.2-11.el6.x86_64.rpm
# rpm -ivh cloog-ppl-0.15.7-1.2.el6.x86_64.rpm
# rpm -ivh cpp-4.4.5-6.el6.x86_64.rpm
# rpm -ivh gcc-4.4.5-6.el6.x86_64.rpm
注：以上是安裝gcc，軟件安裝順序不能錯。
