When Linux is low on memory, you can use swap to prevent errors

1. create partition file, size 2G

if=/dev/zero of=/swapfile bs=1k count=2048000

2. Generate swap file system

Mkswap/swapfile

3. Activating swap Files

Swapon/swapfile

There is a problem with the wood, but this does not automatically mount the swap partition when the system restarts, so we need to modify the fstab.
To modify the/etc/fstab file, add the following:

/swapfile  swap  swap    00

This will automatically load the swap file each time you reboot the system.
