systemctl stop apparmor

离线安装gcc

1. 下载gcc及其依赖包

   rm -rf /var/cache/apt/archives
   sudo apt-get -d install gcc-4.8
   sudo apt-get -d install   binutils-doc gcc-4.8-locales gcc-4.8-multilib gcc-4.8-doc libgcc1-dbg libgomp1-dbg libitm1-dbg libatomic1-dbg libasan0-dbg libtsan0-dbg libquadmath0-dbg glibc-doath0-dbg glibc-doc
   

2. 将 /var/cache/apt/archive 压缩打包到内网机器中

3. 在内网机器中解压缩后安装

   cd /root/archives
   sudo dpkg -i *.deb
   

允许ssh root登录

vim /etc/ssh/sshd_config
PermitRootLogin yes

systemctl restart sshd
