1、首先查看系统发行版本
cat /etc/redhat-release
(base) [root@ai software]# cat /etc/redhat-releaseCentOS Linux release 7.4.1708 (Core)(base) [root@ai software]#
我们的系统是CentOS Linux release 7.4.1708 (Core)，
在没有外网的情况下，如何安装gcc
下载RPM包（任选一个源）
国外：
/7.8./os/x86_64/Packages/
国内：
清华源：https://mirrors.tuna./centos-vault/7.8./os/x86_64/Packages/
中科大源：https://mirrors./centos-vault/7.8./os/x86_64/Packages/
163源：/centos-vault/7.8./os/x86_64/Packages/
我选择的是清华源下载，打开网址：
https://mirrors.tuna./centos-vault/7.8./os/x86_64/Packages/
3、依次下载如下安装包全部放在一个文件夹里：
cpp-4.8.5-39.el7.x86_64.rpmgcc-4.8.5-39.el7.x86_64.rpmglibc-2.17-307.el7.1.x86_64.rpmglibc-common-2.17-307.el7.1.x86_64.rpmglibc-devel-2.17-307.el7.1.x86_64.rpmglibc-headers-2.17-307.el7.1.x86_64.rpmkernel-headers-3.10.0-1127.el7.x86_64.rpmlibgcc-4.8.5-39.el7.x86_64.rpmlibgomp-4.8.5-39.el7.x86_64.rpmlibmpc-1.0.1-3.el7.x86_64.rpmmpfr-3.1.1-4.el7.x86_64.rpm
4、安装
执行如下命令安装：
rpm -Uvh *.rpm --nodeps --force
5、验证，gcc --version
(base) [root@ai software]# gcc --versiongcc (GCC) 4.8.5 0623 (Red Hat 4.8.5-39)Copyright (C) Free Software Foundation, Inc.This is free software; see the source for copying conditions. There is NOwarranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.(base) [root@ai software]#
6、验证，make --version

大功告成。
