Create SWAP partition in CentOS

[Amy Adams]

Hello,
I try to install Oracle on CentOS, I installed on a virtual machine, in the installation documentation, it is advisable to have a swap partition of at least 2GB RAM, as I had rented my virtual machine to a 512MB ram, so is my Linux installation ale 1G swap, as I had not planned initially, and I have enough space, I added a new virtual disk to my machine and is the subject of my message, I'd like your help to format and create new virtual disk swap partition. How can I do this? If you have a solution for this then please let me know.

Hello,
Your new record is defined as

/ dev / sdx (where x is a letter).

It is therefore necessary that you find what matches your drive, eg / dev / sdb then you create a new partition using the command cfdisk.
Here is the syntax of the command

cfidsk / dev / sdb

The code to create a swap is 82 I believe. Checks in the list.

I do not find sd in / dev by the cons hd there is

brw-r ----- 1 root disk 2, 0 Jan 10 10:18 hda
brw-r ----- 1 root disk 2, 1 Jan 10 10:40 hda1
brw-r ----- 1 root disk 2, 2 Jan 10 10:18 hda2
brw-r ----- 1 root disk 2, 64 Jan 10 10:18 hdb
brw-r ----- 1 root disk 2, 65 Jan 10 10:18 hdb1

Hello,
When I try the following command

man fdisk

I get the manual pages for the command
but when I try to apply:

[Root @ localhost dev] # cfdisk / dev/hda2
-Bash: cfdisk: command not found

Do you have any idea about this. Please help me with this. Thank you.

Hello,
This simply means that fdisk is installed and that cfdisk does not. In using cfdisk is easier. To install, you logged in as root and install cfdisk with the command:

yum install cfdisk
