yum update -y 

yum upgrade -y 

Add Swap Space

---

Command to create a Swap file.

Note: We are adding 1.5GB here since our test VPS has 512 MB of RAM if you want to add a different size then you can replace it in place of 1.5G

fallocate -l 1.5G /swapfile

To set write permission.[Default permissions only enable for root user]

chmod 600 /swapfile

To set up a swap area on the file.

mkswap /swapfile

To activate the swap file.

swapon /swapfile

Open the following file and add the given content to change it to permanent.

nano /etc/fstab

Add the following line.

/swapfile swap swap defaults 0 0

Now check the free -m size.

free -m

Output:

root@vps:~# free -m
               total        used        free      shared  buff/cache   available
Mem:             468         143          55           0         268         304
Swap:           2047           0        2047

NOTE: Now the added swap space can be seen.

  changes (use the "virtualmin change-license" command).

  The systems currently supported by install script are:

    Red Hat Enterprise Linux derivatives
      - Alma and Rocky 8 and 9 on x86_64
      - CentOS and RHEL 7 on x86_64

    Debian Linux derivatives
      - Ubuntu 20.04 LTS and 22.04 LTS on i386 and amd64
      - Debian 10 and 11 on i386 and amd64

  If your OS/version/arch is not listed, installation will fail. More
  details about the systems supported by the script can be found here:

    https://www.virtualmin.com/os-support

   WARNING! 

  Virtualmin may already be installed. This can happen if an installation failed,
  and can be ignored in that case.

  However, if Virtualmin has already been successfully installed you must not
  run this script again! It will cause breakage to your existing configuration.

  Virtualmin repositories can be fixed using virtualmin-install.sh -s command.

  License details can be changed using virtualmin change-license command.
  Changing the license never requires re-installation.

  Updates and upgrades must be performed from within either Virtualmin or using
  system package manager on the command line.
