Hey, I am new to linux but have been a Windows Admin for many years. I am at a point in my career that is preventing me from moving forward with sys admin jobs as most of them require linux experience. I have no experience with it and was hoping for some ideas on good training sources. Any advice is appreciated.

thankS

Might be a good start; the Linux Foundation is backing that.

I suggest that you buy various pieces of second hand computer equipment, put them together as a working system, and then install Linux on your home made system. I suggest that you install Fedora. Fedora is the free version of Red Hat which is the Linux distribution you are most likely to run into as a system administrator.

I am currently running Centos on my VM Workstation. The DevOps group at my work uses Centos so I decided to get started with that. I am just uncertain where to go from there or what to do.

thanks for the information, I did some research and found that sight just before I checked these responses. I am going through the start of the course now.

So what does the DevOps group use CentOS for? What infrastructure and services do they require? What I mean is not to "get" the big picture but analyse it, break it up and check each part for services Linux does or could provide. Then you can try and build (part) of it at home. CentOS, when in runlevel 3 and depending on the services it needs to provide, doesn't have excessive memory requirements (still more resources is better always) and getting accustomed to accessed machines via SSH and not some GUI is one of the better ways to get acquainted with it IMO. Once you have build your network have a look at resource and incident monitoring, bottleneck analysis, centralized backups and bare metal restore, failovers, remote colos, unification layers and other resilience-enhancing mechanisms, maybe fake an outage and see what it does, maybe replay some real customers problems and see if you can find the cause. No need for any Shimato Dominguez Off-world Colonies as the fun awaits you right here... :-]

I agree with what unSpawn and voido said, and I'd add to it that possibly building a little virtual network (it's trivial to do, especially with docker now), and start building up a sample network environment. Start with the basics; getting the hosts communicating. Then starting adding services. And just build up something that you would build on Windows. You know the typical goals, all you need to do is learn the different ways of doing what you normally do.

Just an idea!

When I was getting started, I read a ton of books on basically anything having to do with Linux. I learned shell commands, networking principles, scripting. It was a bit unfocused, but I had the time and appetite for it. Your mileage may vary, but there are some great books out there that cover all kinds of stuff. The "Linux Bible" series is one of my favourites.

Linux EDX has certification courses but you can audit the courses & take the exams for free.
I'm working on LFS101x & it is a great course.
But you can audit all of the classes that you want.

You can read all the manuals at www.linuxtopia.org and this is a good cli intro http://rute.2038bug.com/index.html.gz
