[[!meta title="Sysadmin bootstrap - the beginning"]]
|
|
|
|
If you read this blog regulary, you probably know that
|
|
I work as a [[sysadmin|tags/sysadmin]] at the
|
|
[ETH Zürich](http://www.ethz.ch).
|
|
|
|
I decided to think about all the services I provide and
|
|
to document them very well, so that anybody else with
|
|
some technical background could redo, what I did.
|
|
|
|
## Motivation
|
|
|
|
For most jobs I've had, it was always one aim to make myself
|
|
redundant, because this proves that I did a good job.
|
|
|
|
Secondly this gives me a good chance to review my infrastructure
|
|
and verify that every services can be brought up again very
|
|
fast and with a minimal amount of time spent from my side.
|
|
|
|
## Step one: The console
|
|
|
|
Probably the most important device in a sysadmins life is the
|
|
own machine. All the cool tools I've found, scripted or
|
|
documentation boundled together took me years of time.
|
|
|
|
Sure, most of the stuff is also mirrored to my brain, but
|
|
definitely not perfect, nor very easy to share with others.
|
|
|
|
Thus if I had to restart my job as a sysadmin, the first steps
|
|
I would take, are the following:
|
|
|
|
* Get a machine (if it's a notebook, desktop, mobile phone doesn't matter)
|
|
* Setup with an OS
|
|
* Copy existing data to my home folder
|
|
* Setup company specific details
|
|
|
|
Now I would be ready to start working. But from my experiences, I would
|
|
add two more things before beginning to work:
|
|
|
|
* Setting up regular backup
|
|
* Get a second, mostly identical machine
|
|
|
|
I guess the reasons for having a backup is clear for every sysadmin reading
|
|
this. The reason for the second device may not be clear for everybody:
|
|
|
|
If my console dies (and hardware does that pretty often), I'm unable to
|
|
work until I setup a new machine. Thus the first security to create in
|
|
my job as a sysadmin, is to ensure **I** can work and resume working
|
|
after a damage as soon as possible.
|
|
|
|
## Upcoming posts
|
|
|
|
This post is the start of a small series containing all the steps needed
|
|
to the current infrastructure I maintain in the
|
|
[Systems Group](http://www.systems.ethz.ch). Upcoming posts will be both
|
|
tagged with **eth** and **sysadmin**.
