Linux environments Create swap partitions

Recently in the ready to run on the mobile side of the deep learning training model, on the RK3399 board installed scipy times wrong. Online check, because of insufficient memory, make a swap partition is done. So how do you swap partitions? Talk not much, directly open the.

--------------------------------------------------------------------------------------------------------------- ----------------------

To create a swap file with the fallocate command

fallocateA program is the best way to immediately create a pre-allocated file size.

The following command will create a 1GB size /swapfile .

sudo fallocate-l 1g/swapfile

Check to see if the file you created is the correct size.

ls -lh/swapfile11. 0G June  7:/swapfile

Set the file's permissions so that 600 only the root user can access the file.

sudo chmod  /swapfile

Convert this file to a swap file by running the following command.

sudo mkswap/11024x768 MiB (1073737728  bytes) No label, UUID= cda50e0e-41f3-49c7-af61-b8cb4a33a464

Make the swap file effective by running the following command.

sudo swapon/swapfile

Add the newly created interchange file to fstab the file, so that changes to the swap partition space can take effect even after a restart.

vi /etc/fstab/swapfile  swap  swap  defaults  00

Check the newly created interchange file.

$ swapon--showname      TYPE       SIZE   used PRIO/dev/sda5 partition    657.8M   - 1 file      1024M     0B   -2

Now I can see a new 1GB /swapfile1 file. Restart the system for the new swap file to take effect.

Focus: Above just describes how to create a swap partition, on the RK3399 board, I actually created a 4G swap partition!!!

Look at my situation.
