After redhat is automatically installed with kickstart. cfg, mount the ISO image and copy the file from it.

# Copyfilesfromtherel. isoimagetosystem...

# copy files from the rhel.iso image to system                                                                                        if [ ! -b /tmp/cdrom ];then    echo "make cdrom node using mknod" >> /root/ins.log    # get the major number    major=$(lsblk |grep rom | awk '{print $2}' |awk -F : '{print $1}')    # get the minor number    minor=$(lsblk |grep rom | awk '{print $2}' |awk -F : '{print $2}')    echo "major=${major}  minor=${minor}" >> /root/ins.log    # make sure we have what we need; create device node if so    [ -n "$major" -a -n "$minor" ] && mknod /tmp/cdrom b ${major} ${minor}  fi    echo "mount the iso to /mnt/source" >> /root/ins.log  [ ! -d /mnt/source ] && mkdir -p /mnt/source  mount -t iso9660 -o ro /tmp/cdrom /mnt/source  

In this case, the installation image rhel. iso will be mounted to the/mnt/source directory, and the script for copying files will be added under % post in kickstart. cfg.

# copy the id_rsa.pub to authorized_keys  [ ! -d /root/.ssh ]  && mkdir -p /root/.ssh  cat /mnt/source/id_rsa.pub >> /root/.ssh/authorized_keys  [ $? -ne 0 ] && echo "copy id_rsa.pub to authorized_keys failed." >> /root/ins.log  

 

Original problem: you can use kickstart to redhat. the content of the cfg file is automatically installed on kickstart. add the % post tag to the cfg file to execute some scripts after the installation is complete. these scripts are placed behind the % post tag. But one problem is that after the OS is installed, if we want to copy a file from the original ISO image to the installed system, we must mount it. the above code implements its function.
