I was in your same shoes 3 years ago when I took my first SA internship. I was the only person on site for 8 employees locally, 30 around the country.
I was scared to make actions at first but the first thing you need to do is learn your network in and out and document the shit out of everything before you even make a change. After that, you will be confident and I am sure of it.
1.) Begin a document called "IT Department Handbook" - add everything you find to it, except passwords. Refer to it, love it, it will always save you. Include disaster recovery in it. Make it so that a third grader can understand it. I have one thats 50 pages right now. This will save you as it has saved me so many times. Make it confidential though, because it will end up holding information you don't want people to see on the outside such as IP addresses and your network map.
2.) Keep passwords file but separate from the system and indistinguishable. I actually keep a password file on my phone in my memo's app but I don't have the full account usernames associated with each one. I provide really indistinguishable hints to the username, usually riddles that only I would know.
3.) Get Veeam endpoint backup and find a place to backup your DC (full backup) and any databases at the very least. You can create a standard for backups later.
3a.) Find the Domain Controller's recovery password immediately.
3b.) Create a recovery USB for all your servers and put them in a location where you can find them later.
4.) Get a Network Diagram going, then after that...
5.) List all Roles and Features each server has on the network diagram, what each server stores, what applications run on them and how essential they are to the business. Example: Domain Controller. No domain controller, no work can be done. CRM: No crm, people can't keep of their cases on the webserver but rather locally, they can live without it for a short time. Start thinking about disaster recovery.
6.) Develop a Khanban System. It's an agile project management method I learned from reading This Book -- I highly suggest buying this to help you better your practice. Put tasks in the backlog and move the ones you think need to be done sooner than others to your daily or weekly sprint.
7.) Find out who uses what server for certain tasks. This may take a while but it helps.
8.) Something I do personally before doing any changes to Group Policy or Regedit is I save their current configurations before making changes. Therefore, if something doesn't work right after a setting is changed, you can quickly revert back to it's last state.
9.) If you have the capability and hardware, get clustering going. So if a DC1 fails, DC2 takes over and everyone can still authenticate and work.
10.) If you have the capability and hardware, create a test environment reflecting your live network on a very small scale but enough to test "Ok so if I make this change, can people from workstations still login, can they still access the development server... etc." - you can create a test domain under your current forest and have it remain separate in this test environment.
11.) If it's not already in place (this might take some time) create a naming nomenclature standard. I.E. DC1.example.com (domain controller 1), DC2.example.com, PS1.example.com (production), WEBS1.example.com (webserver), TE1.example.com (test env.), WK1.example.com (workstation number 1...2...), VM1.example.com (virtual machines). This will help when it comes to debugging issues. My boss likes to make personal names for his servers which drives me fucking nuts because we have 20 servers between us and our clients that we manage. It's a lot better for him to mention "yea I cant get into PS1." rather "I cant get into rabbit" - and there I am trying to remember which server rabbit is and what features it holds off the top of my head; which is where a network diagram can come into play.
This book has been suggested a few times so I finally got around to reading it. I think it has some good information in it. I'm only about halfway through it, but I like it so far.
Time Management for System Administrators
Other books would be any of the social books like "How to influence people", "7 healthy habits..." Etc.
I haven't read this one yet, but It has been suggested to me if you plan to go more into management/leadership Start with Why
Other books that have I have ear marked due to being mentioned:
Also, do a search for "Books for IT Professionals" to find a lot of other suggestions.
Big fan of that book. New edition due soon too!
You will pick up the knowledge fairly quickly, but the wisdom part comes slowly.
Read some books:
Start humble, stay humble, be quick to listen and slow to speak, and don't make changes on Friday!
The Practice of System and Network Administration.
A few general principles:
Even more formatting fun!
By the way, thank you for this list.
Worth noting that there is a third edition that is significantly updated. I own both would say they're both good but you'll get a lot more out of the third edition.

The senior part is more of a technical grade level and not necessarily management... granted I'm in the lead role here, it's my first time as one. All I can say is what help me spring forward at a lull at mid-level was picking up Thomas Limoncelli's books, [the sysadmin one] (https://www.amazon.com/Practice-System-Network-Administration-Enterprise/dp/0321919165/ref=sr_1_1?ie=UTF8&qid=1512041042&sr=8-1&keywords=thomas+limoncelli) and [the cloud one] (https://www.amazon.com/Practice-Cloud-System-Administration-Practices/dp/032194318X/ref=sr_1_3?ie=UTF8&qid=1512041042&sr=8-3&keywords=thomas+limoncelli) /r/sysadmin recommends them too. These are your best practice books, these tell you why to do things, not how. It will turn you from being the guy that mops the floor in a burning building into knowing when to yell, "FIRE!"
Cert wise, unless a specific company or contract requires it, I don't bother with the time and money on certs if you already have years of experience on the books. I'd probably go for a Security+ and then go for a Red Hat and/or CCNA certification as they are both prestigious. Red Hat is a big deal just by its practical application test.
If you want to go into cloud related stuff, you might want to brush up on your programming. This is what is limiting me, I have very minimal bash scripting experience coming from military in the Windows world then making a move to Linux.
Honestly, I would focus on being both as they both overlap very often unless you are in really large stovepipe enterprise environments, but you never know if you need to make a move to something smaller where you have the many hats role. I'd get your degree in something Computer science related (CS, CIS, EE, CE, etc) and then go RHCSA/CE and maybe Sec+/Net+ or instead of Net+ just go for something Cisco related. My networking is Net+ strength at best and I resent not doing better when I was younger.
EDIT: Also, if you can do the math, BS is Computer Science all the way... sysadmins are still really kind of not doing well in the degree program department, mainly because were so... trade-like I guess. Honestly, we're the new Millwrights like my dad was. We keep the factory going and fix it when production stops. It's kind of cool actually, it's nice to be able to have some kinship to my dad in that way.
https://www.amazon.com/Practice-System-Network-Administration-Enterprise/dp/0321919165/
Honestly, you are never going to find a way to shortcut you out of this situation. No one answer is going to be perfect and get you from A to B if your already at C. I had a similar experience with programming and web development.
I studied computer networking all my adult life and never thought I would be developing as my career at the moment. It is the burden of knowing too much and not having a clear direction. What I needed was more confidence in my skills which can only really develop over the years through experience.
You say you already know a lot of Linux and Bash concepts. CD/CI pipelines try to abstract a lot of OS related involvement since your code doesn’t need to know how low level kernel operations are happening.
What it sounds like you need is knowledge of OS concepts, not just Linux concepts. I say this because every OS has its own way of doing the same thing one way or another.
For example virtual memory, if you understand the concept of virtual memory in any OS rather than a specific OS’s semantics regarding Virtual memory then I think you would be better off in the long run.
If I am wrong and you are the master of the Linux environment, I believe you just need to deep dive into development strategies and the core principles of CD/CI. Once you have a foundation it doesn’t really mater if you are a Jenkins expert or CircleCI expert, all that matters is if you have a foundation to fall back on.
Edit: if you wanted my two cents on material here are some books I recommend.
The Practice of System and Network Administration
Operating Systems Concepts
UNIX and Linux System Administration Handbook
'Best practice' is such a vague term that you're going to run into issues defining it in a meaningful way for your client's environment.
I'd look at generic guides (u/jhend28 mentions a good one) but also read up on specifics that apply to your environment. For example: best practice for a level 4 data center hosting financial data for banks etc. will not apply at all you a SME with two servers on premise that don't sell direct and hold no Top Secret data.
Have a read of The Practice of System and Network Administration: Volume 1 for a good starting place.
As far as recommended reading goes I would have a look at the practice of system and network administration (https://www.amazon.com/Practice-System-Network-Administration-Enterprise/dp/0321919165/ref=sr_1_1?ie=UTF8&qid=1539629401&sr=8-1&keywords=practice+of+network+and+system) and The phoenix project. As far as technical courses, I'm assuming your role will be mostly strategic and managerial (unlike some of us in smaller companies where the IT Manager is also expected to be a technical lead) I would focus on the managerial side and surround yourself with technical experts.
A few thoughts. Hopefully at least one of them will be helpful.
I could go on, but most of the above is already in the two books I listed and I'd just be riffing on a theme. I'll leave you with this:
Is this the one you mean? I am looking for some good books to read as I start to enter the work force.
https://www.amazon.ca/Practice-System-Network-Administration-3rd/dp/0321919165
Read Limoncelli's book: The Practice of System and Network Administration: Volume 1. That would give you a good place to start and learn best practices.

Probably the best book out there for system administration.
https://www.amazon.com/Practice-System-Network-Administration-Enterprise/dp/0321919165/ref=dp_ob_title_bk
Thanks for linking this, I hadn't seen it yet. As a Windows admin looking to get into Linux, this seems interesting.
Also, for your automation, I'd recommend Automate the Boring Stuff with Python, if you haven't read it already. It can also be found for free here: Automate the Boring Stuff.
I'll add another plug for The Practice of System and Network Information, even if you have a good feel for the philosophical part of the job.
Also, https://www.amazon.com/Practice-System-Network-Administration-Enterprise/dp/0321919165/ref=pd_sbs_14_t_0?_encoding=UTF8&psc=1&refRID=0T9DJZC3VHQTS8MFT7WT
If you wait a few weeks, you can pick up the new edition of this book:
https://www.amazon.com/gp/product/0321919165/
If you think "there is nothing to do", you are probably in "don't know what you don't know" territory, which is fine. They key is to first start discovering what you don't know, then you can start taking steps to resolve it by learning.
As you learn, you will realized that there is far more that you don't know than you though, and the side effect will be that you feel dumber and dumber, but you will actually be improving at your job.

Learn to program. Edx/Harvardx CS50x gets pretty good reviews.
Learn to and make a habit of writing extensive technical documentation on everything you do.
Read this book. https://www.amazon.com/Practice-System-Network-Administration-Enterprise/dp/0321919165/ref=sr_1_1?ie=UTF8&qid=1480705767&sr=8-1&keywords=The+Practice+of+System
Apply everything you learn to the current systems you work with
must read the [third edition](
https://www.amazon.com/Practice-System-Network-Administration-Enterprise/dp/0321919165/ref=sr_1_1?s=books&ie=UTF8&qid=1520930004&sr=1-1&keywords=the+practice+of+system+and+network+administration&dpID=5139XV0QYsL&preST=_SX218_BO1,204,203,200_QL40_&dpSrc=srch) instead of the second
Even earlier versions would be a very good read despite the DevOps hype, but the 3rd (new) version includes best DevOps practices even without having any devs.
First, read our Wiki. It is very thorough and answers a lot of these common questions such as
day to day? The Practice of System and Network Administration
And the topical reference books listed below.
Books to help in shaping a sysadmin? The above &:
The Phoenix Project
Time Management for System Administrators
Topical Books I see mentioned often and have been very helpful to me:
Powershell in a month of lunches
Learn Python the hard way
Unix and Linux System Administration Handbook
Windows Server 2016: Inside Out
Group Policy
AbsoluteBSD
FreeBSD mastery:ZFS
CCNA
RHCSA/RHCE
Pro Puppet
SSH Mastery
On my docket:
FreeBSD Mastery: Advanced ZFS
Michael W. Lucas and Thomas Limoncelli are very good sysadmin writers, you can't go wrong with a topic they have chosen to write about.
Most of the *nix stuff assumes a baseline knowledge of how to use a unix-based system. I learned as I went but did pick up an old copy of Unix Visual Quickstart Guide not too long ago at a used books sale, which seems like a good starting place for someone overwhelmed with sitting at a terminal and being productive.
I notice I don't have any Virtualization books, perhaps someone else can fill in good books. Most of my knowledge regarding virtualization and network storage has been a mix of official docs, video training, and poking at it. Seems innate but it isn't.
Sounds like you're asking for a link to https://www.amazon.com/Practice-System-Network-Administration-Enterprise/dp/0321919165/ref=asap_bc?ie=UTF8
https://www.amazon.co.uk/gp/product/0321919165/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1 deals with a lot of issues, among them support/helpdesk/people stuff.
I am in a similar boat as OP and also found the book you recommended, so just wanted to add that there is a new edition coming very soon, the one you linked is from 2007.
https://www.amazon.com/Practice-System-Network-Administration-3rd/dp/0321919165
Check out "The Practice of System and Network Administration: Volume 1: DevOps and other Best Practices for Enterprise IT (3rd Edition)" by Thomas Limoncelli.
https://www.amazon.com/dp/0321919165
I'm also pretty new to this job, and this book has been really helpful in better understanding all that we get to do.
Did you get that old edition or the latest 3rd edition with it's cloud admin partner?
Also read this book

The Practice of System and Network Administration: Devops and Other Best Practices for Enterprise it
Or for cheap starters, this book with an overly long title:
The Practice of System and Network Administration: Volume 1: DevOps and other Best Practices for Enterprise IT (3rd Edition)

So I have the MCSE Mobility and I do not know if that alone will last.
Would rather say it depends on your skill. You can also become a sysadmin without a certificate as the others have already mentioned. The MCSE Mobility does not really go deeper into server landscapes like the MCSA Server 2016 does.
The topics to be covered is:
Deplyoment
Inunte
And SCCM with intune I think.
I chose Deployment because I already had experience.
This contains:
LTIDeployment (mdt)
ZT Deployment (sccm)
WDS
USTMIf you really want to go deeper I can recommend the following book
is also recommended here in the wiki.

I'm going to recommend a book: https://www.amazon.com/Practice-System-Network-Administration-Enterprise/dp/0321919165
Read the first edition of this 20 years ago. Great book about doing the "job" of being a sysadmin. Nothing OS specific.
Also, learn a scripting language. You're not a real IT guy unless you know one. Python is my preference, but PowerShell is fine if you primarily work in a Windows environment.
3rd edition was just released.

A+ and Net+ and all the other +-certs are entry level. CCNA is entry level, and 70-680 is entry level.
Something to consider is that everyone has certs these days, so the certs you get must make you better than "everyone".
For example, CCNP is a rather high-end cert. You don't see a lot of CVs with this on, because people with this cert only need a Linkedin page, and the offers will come in endless streams.
MCSE is absolutely good to have if you want to go anywhere in a Microsoft environment, though Microsoft doesn't really do high-end certs anymore, so the only thing you can really aim for with an MCSE is an MVP award, but that does take some serious effort.
WCNA is worth some brownie points in the right places.
You should also supplement certs with in-depth knowledge, and recommended practices, for example,
I can't really help much with regards to Linux though. It's not really my area.
nice - added https://www.amazon.com/dp/0321919165 to buy list.
Putting asside VA_Network_Nerd's condescending advice. If you want to go anywhere in your career you need to go beyond google. I'd go to indeed or DICE and search for Network Administrator or jr network admin in your area then look up job requirements and preferences.
Set up a GNS3 or Virl lab, or just buy some cheap switches/routers on ebay for homelab.
Get your CCNA. There should be no debate that CCNA is best for network admins starting out. I personally wouldn't let someone touch my network without at least a CCNA. Get hands on with Windows and Linux servers and various tools like nmap, nagios and other monitoring tools, wireshark.

The Practice of System and Network Administration
I also use cbtnuggets.com for my IT training. It's more than worth the monthly fee if you stick to it.
Sure.
Good luck. You'll do fine.
I was in the same boat 2 years ago. Go and purchase a copy of this book and read as much as you can. This is the best book out there and will give you an idea of how IT should be handled.
Be upfront with whoever you answer to about the situation. Its bad, and it may get worse. Don't make promises you can't fulfill. If there is anything sketchy (i.e. licensing etc) make sure everything is in writing to CYA. The previous IT person left for a reason.
I would start with validating login credentials for all key systems and ensure you have administrative access followed shortly by evaluating backups, and mission critical services. If you don't understand what something does, don't touch it until you do.
Have the backups been tested, how often are they done, What would happen if x server went down. It doesn't need to be detailed at first and RAID is not a backup. How long is the RTO (Return to Operation) from a critical disaster?
Documentation takes time, but this is what they pay System Administrators for and why they make the big bucks.
Without documentation you can't do your job, you can't take a vacation, and the business will grind to a halt. Its that important.
If you don't have administrative credentials and the previous person was halfway proficient a complete rebuild from the ground up is the most cost-effective longterm solution.
Infrastructure is a foundation, you need it solid before building on it and if it wasn't done properly to begin with its better to have it designed right the first time. If you can't do it then bring in a consultant but it will be expensive.
Edit: I almost forgot. Keep a personal composition book with you, when you find a solution for something write it down. I've found so many solutions and 6 months down the line needed it again but couldnt' remember. This guarantees you won't spend a lot of time searching for the same solutions multiple times.
Only a small thing, but your link goes to the 2nd edition of the book, and now there is a 3rd edition.
Hopefully people can figure it out, but I don't want an errant bystander to accidentally get and older version.

When I tried to go through the automated exchange process it said I didn't have a credit card on file when I clearly do. Phone support was able to process the exchange, but my experience with Amazon for this hasn't been great.
Do yourself a favor, either buy The Practice of System and Network Administration or get it from the library. Make sure it's the 3rd Edition. Read Chapter 49 Perception and Visibility on page 913.
Pay special attention to 49.1.2 Attitude, Perception, and Customers on Pg. 918.

Just wanted to add, it seems that there is a newer version here. Considering picking this up myself!
Give me a DM if you need some help and I am cool pointing out resources or giving some pointers. The key is to make the data in the end valuable, instead of a jumble of graphs.
It was recommended to me by the Practice of System Administration book, which I highly recommend as it outlines many great 2017-2018 practices .
The 3rd edition was released a couple of months ago:
[Amazon] (https://smile.amazon.com/Practice-System-Network-Administration-Enterprise/dp/0321919165/ref=sr_1_1?ie=UTF8&qid=1484778994&sr=8-1&keywords=the+practice+of+system+and+network+administration)
> As for a Sysadmin Bible, i would recommend the book: The Practice of System and Network Administration: Devops and Other Best Practices for Enterprise it.
This is going to sound dumb, but I don't want to spend $50 for the same book. I have "The Practice of System and Network Administration: 2nd Edition", already:

The DevOps one (3rd edition) is an entirely different book, right? Or is it just the 2nd edition with some DevOps stuff added to the end? Hard to tell when taking the Amazon page at face value.
