Resize Linux partition

Hello.,

Could any one please share the informaiton about this or please point me the reference :

Assume, we have the following partition after linux machine is setup, it will mention like this :

Code:
bash$ df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/xvda2             10G  5.0G  5.0G  50% /
/dev/xvda1             99M   30M   65M  32% /boot
tmpfs                  46G     0   46G   0% /dev/shm

And i want to resize /dev/xvda2 to increase from 10G to 20G without impacting the machine, can any one please share instruction on this. Should i use FDISK after adding the disk space to /dev/xvda ?

Thanks
