If you want to add a swap swap partition in a linux system, how do you add it?

2. Then set the password to the root user, because the installation process is the administrator user, and the root password is not set.

Sudo passwd root

3. After the setting is completed, execute the su command to switch to the root user

4, execute the following command, generate swap file in the root directory, set the number of blocks by count, set the block size by bs, and generate 4G swap.

Dd if=/dev/zero of=/swapfile count=4096 bs=1024k

5. Next, you need to set it to swap partition (the path is the same as the path above).

Mkswap / swapfile

6. Mount the swap partition (the path is the same as the path above).

Swapon / swapfile

7. Execute the top command at this time to see the corresponding swap partition information.

2. Automatically mount swap when powered on

1. Next, to mount automatically when booting, open the fstab file with vim:

Vim / etc/fstab

2. Press the G key, switch to the end of the file, and append the following

/ swapfile swap swap defaults 0 0

3. The wq command saves and exits vim.

4. Restart the computer and you can see the effect.
