Two new methods for creating SWAP space in Linux (2)

Two new methods for creating SWAP space in Linux operating system (2) -- Linux general technology-Linux technology and application information. For more information, see the following. 1. Use the dd command to create a file for SWAP

For example:

[Root @ RAID/] # dd if =/dev/zero of =/nihao123 bs = 1 M count = 100

100 + 0 records in

100 + 0 records out

If -- the device that generates the empty file

Of -- name Of the file to be generated

Bs -- size of each group

Mount -- total number of rented instances, bsXcount = SWAP size !!!

2. format the generated file/nihao123

For example:

Mkswap/nihao123

3. Use the swapon command to activate SWAP

For example:

Swapon/nihao123
