Installing webmin on Ubuntu Server

Same disclaimer as last post: This is mostly for my memory, but you’re welcome to the comments section below.

This is for Ubuntu Server 12.04 64-bit.

In order to install webmin from apt, follow these instructions, reposted here for my own convenience:

edit /etc/apt/sources.list and add to the bottom:

deb sarge contrib
deb sarge contrib

then, to add the gpg signature, run:

sudo wget -O - | sudo apt-key add -

lastly, install:

sudo apt-get update
sudo apt-get install webmin

If it complains about missing dependencies, first edit /etc/apt/sources.list and uncomment any lines for universe. Then, install these:

sudo apt-get install perl libnet-ssleay-perl openssl libauthen-pam-perl libpam-runtime libio-pty-perl apt-show-versions python

Coming up…even more…

Installing Ubuntu Server 12.04 LTS x64 on the HP MicroServer N40L

I’m mostly documenting this as a way for me to remember it, but anyone is free to learn from my doings or leave their own comments.

Configuration is 3x2TB hard drives in bays 0, 1, 2. Bay 3 is empty. (I’m considering adding a 4th 2TB drive and reshaping to RAID-6 at some point in the future.)

Partitioned as follows (MBR):

  1. 50GB as RAID
  2. 4GB as RAID
  3. 1.9TB (max) as RAID

RAID setup (mdadm) as follows:

  • md0: partition 1 (50GB) RAID-5, 3 units, 0 spares. EXT4, bootable, mounted at / [Total 100GB+parity]
  • md1: partition 2 (4GB) RAID-5, 3 units, 0 spares. swap [Total 8GB+parity]
  • md2: partition 3 (1.9TB) RAID-5, 3 units, 0 spares. EXT4, mounted at /srv [Total 3.8TB+parity]

Packages installed during installation:

  • OpenSSH
  • LAMP
  • Samba

GRUB installed to MBR

The very first thing to do after installation is to update. SSH in and run the following:

sudo apt-get update
sudo apt-get upgrade

May get the following complaint about kernel updates being held back:

The following packages have been kept back:
 linux-headers-generic-lts-quantal linux-image-generic-lts-quantal
0 upgraded, 0 newly installed, 0 to remove and 2 not upgraded.

This is the fix:

sudo apt-get dist-upgrade

Coming up… more installations…
