已经在RHEL7.3上搭建了ApacheWeb服务，现在想把RHEL8.1系统镜像上传到ApacheWeb根目录下，但是由于RHEL8.1系统镜像的大小是7.31GB，所以有超过4GB，无法通过rz上传。解决方法是将RHEL8.1系统镜像挂载到RHEL7.3系统上然后新建一个系统镜像，然后将新的系统镜像移动到ApacheWeb根目录下的系统镜像目录下，或者到ApacheWeb根目录下首先在系统镜像目录下新建一个系统镜像，这样移动新系统镜像的步骤就可以省略了。环境RedHatEnterpriseLinuxServerrelease7.3VMwareWorkstationPro14添加镜像[root@Jaking~]#ifconfigens32:flags=4163mtu1500inet192.168.10.10netmask255.255.255.0broadcast192.128inetfe80::20c:29ff:fe84:eae5prefixlen64scopeid0x20ether00:0c:29:84:ea:e5txqueuelen1000（以太网）RX数据包636字节53068（51.8KiB）RX错误0丢弃0溢出0帧0TXpackets508bytes85327(83.3KiB)TXerrors0dropped0overruns0carrier0collisions0lo:flags=73mtu65536inet127.0.0.1netmask255.0.0.0inet6::1prefixlen128scopeid0x10looptxqueuelen1（本地环回）RX数据包4字节340(340.0B)RX错误0丢弃0溢出0帧0TX数据包4字节340(340.0B)TX错误0丢弃0溢出0载波0冲突0virbr0:flags=4099mtu1500inet192.168.122.1netmask255.255.255.0broadcast192.168.122.255ether52:54:00:25:a2:80txqueuelen1000(以太网)RX数据包0字节B0(0.0)RXerrors0dropped0overruns0frame0TXpackets0bytes0(0.0B)TXerrors0dropped0overruns0carrier0collisions0[root@Jaking~]#df-hFilesystemSizeUsedAvailUse%Mountedon/dev/mapper/rhel-root48G4.9G41G11%/devtmpfs478M0478M0%/devtmpfs489M0489M0%/dev/shmtmpfs489M6.7M482M2%/runtmpfs489M0489M0%/sysgroup//fs/cdev/sr03.6G3.6G0100%/media/cdrom/dev/sdd40G27G14G67%/download/dev/sda21014M145M870M15%/boot/dev/mapper/rhel-data10G33M10G1%/数据tmpfs98M098M0%/run/user/0[root@Jaking~]#ls/dev/sr*/dev/sr0/dev/sr1#/dev/sr1为新添加的镜像制作新的系统镜像切换到ApacheWebroot目录下的系统镜像目录[root@Jaking~]#cd/download/systemimage/[root@Jakingsystemimage]#lsCentOS-7.6-x86_64-DVD-1810.isorhel-server-7.3-x86_64-dvd.isoWindows7x64.isoLaoMaoTao.isoubuntu-18.04.1-desktop-amd64.isoWindowsSever2008.isorhel-server-6.5-x86_64-dvd.isoWindows2003SP2.iso[root@Jaking系统映像]#ddif=/dev/sr1of=RHEL-8.1.iso15335424+0recordsin15335424+0recordsout7851737088bytes(7.9GB)copy,174.329s,45.0MB/s通过web界面查看新系统镜像http://192.168.10.10/系统镜像/下载镜像，使用watchifstat实时查看网卡流量
