Problem:
Because I did not look carefully when installing the system, the default setting of the /boot directory is only 100M, so the /boot space is not enough to compile several versions of the kernel. . Mount it and see that the /boot directory is mounted on /dev/sda1, with only 100M of space.
(Recommended tutorial: centos usage tutorial)
The solution is as follows:
1, umount /boot
2, mkdir /boot_old
3. mount /dev/sda1 /boot_old
4. Go to the /boot_old directory: cp -rp * /boot
5. Delete /etc/fstab The table contains the /boot item
This method is to cancel hanging /boot on sda1 and use the /boot directory directly, but you need to copy the files originally on /dev/sda1 to /boot .
