Increase swap on Centos 6

Increase swap on Centos 6 

CentOS

 

Present we are having 1gb SWAP disk and we want to increase to 3gb SWAP disk on CentOs.

Step 1:  Check current swap status by top command or cat /proc/meminfo.

Step 2:  Create swap image with dd command with 2gb more.

 

Step 3: Make swap image with mkswap command.

 

 

Step 4:  Need add swap image to /etc/fstab to map the swap image when server reboots.

 

Step 5:  Mount swap to server by swapon command.

 

Step 6:  We also can use “top” command to check swap , RAM and CPU of our server.

 

That’s all. Thanks for using IThelpblog.com.
