Workaround:

1. Check swap space before you set up swap files, it is necessary to check the system for any existing swap files. Run the following command:

1 swapon-s

If the summary of information returned is empty, then the Swap file does not exist.

2, check the file system before setting up swap files, it is also necessary to check the file system to see if there is enough hard disk space to set swap. Run the following command:

1 Df-hal

3. Create and allow swap files to create swap files using the DD command below. Check the returned information and have enough hard disk space left.

1 dd if=/dev/zero of=/swapfile bs=1024 count=512k

Parameter interpretation: if= file name: Enter the file name, default to standard input. The source file is specified. < if=input file >of= file name: Output file name, default is standard output. That is, the specified destination file. < of=output file >bs=bytes: Set the read/output block size to bytes bytes Count=blocks: Copy only blocks blocks, the block size equals the number of bytes specified by BS.

4, format and activate swap file above has created a good swap file, but also need to format before use. to run the command :

Mkswap/swapfile

To activate Swap, run the command :

Swapon/swapfile

Finish the above steps and run the command again:

Swapon-s

You will find a summary of the information returned:

1 Filename Type Size used priority2/swapfile file 524284 0-1

If the Swap is mounted automatically when the machine is restarted, then the fstab configuration needs to be modified. Open the/etc/fstab file with vim and add the following line at the end:

1/swapfile swap swap defaults 0 0

Finally, give the Swap file the appropriate permissions:

1 chown root:root/swapfile 2 chmod 0600/swapfile
