Two new methods for creating SWAP space in Linux (1)

Two new methods for creating SWAP space in Linux operating system (1) -- Linux general technology-Linux technology and application information. For more information, see the following. Linux SWAP space can be created in two ways: partition and file. That is to say, the space provided as a SWAP can be provided in the form of partitions and files!

Partition type:

1. To use a partition for SWAP, prepare an unused partition, such as/dev/hdd4. Use the t option of the fdisk tool to modify the tag of this partition and change it to 82.

2. Use the mkswap tool format.

For example:

[Root @ RAID/] # mkswap/dev/hdd4

3. Use the swapon command to activate the/dev/hdd4 partition as the SWAP

For example:

[Root @ RAID/] # swapon/dev/hdd4

4. Use swapon-s to check whether swapon-s is used.

For example:

[Root @ RAID/] # swapon-s
