Add swap Partition

 

After determining the memory used by the server, we need to increase the swap space by MB.

 

Specific operations:

 

1. dd If =/dev/Zero of =/tmp/swap BS = 1 m COUNT = 1024 M # create a file block of m

 

2. mkswap/tmp/swap # create a swap file

 

3. Swapon/tmp/swap # activate the swap file

 

4. Swapon-s # view swap

 

5. Modify the/etc/fstab file and add the following content to enable automatic startup during system boot.

 

VI/etc/fstab # Add the following code at the end

 

/Tmp/swap default 0 0

 

: WQ! # Save and exit
