Adjust Swap Space Size in Linux

In a Linux system, the size of the swap space can be configured using the following methods:

1. I only need one option.
2. create a swap space
3. Activate a swap file or partition

sudo dd if=/dev/zero of=/swapfile bs=1G count=2
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile

1. The configuration file for file systems is located in /etc/fstab.
2. The file system table in the Linux operating system.

/swapfile swap swap defaults 0 0

1. deactivate

It’s important to note that the size of the swap space should be determined based on the system’s memory size and usage. Generally, the swap space should be set at two to three times the physical memory. A swap space that is too small can cause the system to crash when memory is insufficient, while a swap space that is too large may waste disk space.
