Install Slackware on a CloudVPS by ArubaCloud

ArubaCloud offers excellent low-cost VPS services, starting at 1 € / month (at least when this article was created, feb. 2018, see ArubaCloud limitations). This article refers to installing Slackware on CloudVPS hosting service, which is based on VMware virtualization hypervisor and uses several OS templates, Slackware not being among them. As a low-cost service, custom OS installation, management with VMware Client are not available. You can request a free trial here.

This guide does not cover Cloud Pro or other services by ArubaCloud.

Prerequisites

Assuming you want a Slackware server hosted at ArubaCloud, here is what you need:

  • ArubaCloud account
  • enough credit to creat the CloudVPS you want.
  • a FTP hosting space with several GB of available space and reasonable speed.
  • VMware Player on your computer and at least as much free space as the CloudVPS virtual HDD

Initialization

Once you get your free trial voucher or you purchased credit, you can follow ArubaCloud's web interface to create the CloudVPS of your choice. Using the free trial voucher you can get 2 months free trial for CloudVPS Small (1xCPU, 1GB RAM, 1xETH, 20GB HDD, 2TB traffic/month).

  1. load credit into your account (free trial voucher or purchase credit)
  2. create VPS based on predefined OS template

This guide has been written using an Ubuntu 14.04 LTS template.

Information gathering

Having the VPS up and running, and after receiving your access credentials, first write down some key information:

  • HDD size and layout
  • Public IP (of the VPS), including netmask, gateway

Preparations

Log in to the CloudVPS using SSH.

Show IP and netmask (write it down):

ip addr list

Show default gateway (write it down):

ip route list

Show nameservers (write it down):

cat /etc/resolv.conf

Show disk layout (write down the total disk size in blocks):

fdisk -l /dev/sda

Install ncftp package:

apt-get install ncftp

Optimize disk by overwriting all free space with zeros (helps with compression):

dd if=/dev/zero of=/ZERO bs=1M; rm /ZERO

Export an image of the Aruba created server

Aruba has predefined OS installations as templates, and such a template is deployed into your VPS upon creation. It is personalized with IP address, hostname and you are given an automatically generated password.

Make sure you have enough free space in your FTP account. This will take up several GB of data.

cat /dev/sda | bzip2 | ncftpput -u USERNAME -p PASSWORD -c FTP_SERVER_ADDRESS /path/to/aruba_image_file.bz2
This may take a while, even hours, depending on the available bandwidth between Aruba's datacenter and your FTP server.

It is a rather dirty trick, but it works. The template contains only a bare-bones installation with minimal services running. You may check and see if there is any background daemon that might write much to the disk and stop it, but other then a few log entries, there isn't anything worth mentioning.

Make sure the process finishes without error before proceeding!

You can use this image to make tests on your local VMware Player, and also as a test for the FTP transfer.

Slackware virtual machine

Create your own, local, virtual machine with VMware Player.

  • Start Vmware Player
  • Create new virtual machine
  • “I will install the operating system later”
  • Choose “Linux” and “Other Linux 3/4.x 64bit”
  • Name it (ie. aruba_slack)
  • Maximum disk size: same as VPS HDD size (in GB); store as single file
  • proceed to finish.

Modify the virtual machine you just created as follows:

  • Memory = 1GB
  • Processors = 1 core
  • CD/DVD = use ISO image (select slackware64-14.2-install-dvd.iso locally), connected at power-on
  • Network adapter = NAT, connected at power-on
  • Sound card = REMOVE
  • Printer = REMOVE

Start the virtual machine.

  • Enter the console (click in the VM display area)
  • Proceed to install Slackware as you would on a physical server with the same characteristics of your cloud server. There are no exotic hardware or settings.
For example, you could use a single partition for both system and data, and a small partition (ie. 1-4GB) for swap. Or you could use about a partition for the system, a partition for swap, a partition for data. Your choice.
You are running locally, with the machine behind a NAT router (done by VMware Player) with regards to the internet. You have connectivity, but it is different then the one you'll have at Aruba.

During the configuration phase, assign the proper hostname, but set it to obtain IP address via DHCP.

After the first start of your fresh Slackware installation, you should set up slackpkg and perform an update.
