在RHEL7.3上面搭建好了ApacheWeb服务，现在想把RHEL8.1系统镜像上传到ApacheWeb根目录，但由于RHEL8.1系统镜像的大小为7.31GB，已经超过4GB，通过rz无法上传。解决方法是把RHEL8.1系统镜像挂载到RHEL7.3系统上再制作一个新系统镜像，然后把新系统镜像移动到ApacheWeb根目录里面的系统镜像目录即可，也可以先到ApacheWeb根目录里的系统镜像目录再制作新系统镜像，这样就可以省去移动新系统镜像的步骤了。

环境

RedHatEnterpriseLinuxServerrelease7.3
VMwareWorkstationPro14

添加镜像
