Increase Linuxswap space

Increase the Linuxswap space-General Linux technology-Linux technology and application information. The following is a detailed description. High-risk action. do not try it easily if you do not need it.

Linux swap space is increased. The method is as follows:

Step 1:
# Dd if =/dev/zero of =/home/swap bs = 1024 count = 500000
Note: of =/home/swap: place the swap space. The size of count is the size of the added swap space, and the size of 1024 is the block size. here it is 1 K, so the total space is bs * count = 500 M

Step 2:
# Mkswap/home/swap
Note: format the space in the previous step into various swap types.

Step 3:
# Swapon/home/swap
Note: Make the created swap space
To close the newly opened swap space, run the following command: # swapoff (T002)
