My Current Training Courses on Pluralsight!

Here’s a run down of the Linux training that I have available on Pluralsight!

Just getting started! 

Understanding and Using Essential Tools for Enterprise Linux 7 – If you heard what Linux is and want to get started this is the place to be. We’ll cover installation, command line basics, the file system, text editors and more! This is my most popular course.

SQL Server on Linux Administration Fundamentals – SQL Server is available for Linux and Docker! This course is targeted towards both the SQL Server DBA and the Linux professional to get you started using SQL Server on Linux. We cover architecture, administration basics, Tools and backup and recovery!

Provisioning Microsoft Azure Virtual Machines – Need to deploy a VM in the cloud, start here! We cover the basics of getting started and walk through how to deploy VMs both in the portal and at the command line. We also cover Azure Disk storage and building custom virtual machine images for consistent repeatable deployments. 

Deeper cuts!

Once you’ve mastered the basics let’s move you along in your Linux journey and get your ready to run your applications and servers in production! 

LFCE: Advanced Network and System Administration – If you’re going to run Linux in production, you should watch this course. We cover managing services, system performance, package management and sharing files with Samba and NFS. A must see. This is my second most popular course.

LFCE: Advanced Linux Networking – Tired of the network team saying “I can ping it” if so, watch this course. We’ll learn about the OSI model, addressing and subnets, ARP and DNS, how routing works, TCP internals and my network troubleshooting model!

LFCE: Network and Host Security – Speaking of production ready, this course is a must. We cover security concepts and architecture, Linux firewalls including iptables and firewalld, we also cover remote access with SSH and also cover how to reach applications behind firewalls wiht tunneling services through SSH.  

For the those with services on the internet!

LFCE: Linux Service Management – HTTP Services – Need to set up a web server, watch this course and learn how. We’ll cover Apache’s architecture, how DNS works, installation and configuration, implementing Apache security features and troubleshooting and logging.

LFCE: Linux Service Management – Advanced HTTP Services – Once you have that web server up an online, learn how to really build scalable internet architecture with this course! We cover proxy and caching techniques and also a deep dive into Apache Modules.

LFCE: Linux Service Management – Advanced Email Services – If you’re a consulting customer of mine and you ask me to build you an email server I’m going to tell you to give me your credit card because we’re going to buy a cloud based solution for that. But for those of you who need to know how to build SMTP based mail environments this is your course! We’ll cover installation and configuration of Postfix as a mail server, we cover relay services and how to access your mail server securely.

Installing minikube on CentOS

In this blog post, I’ll show you how to install Minikube on CentOS. Minikube is a platform you can use to test kubernetes clusters on your local machine or in a virtual machine.

Let’s start off with a fresh Install of CentoOS 7 on a virtual machine using a minimal install. If you need some help getting a Linux VM us, check out my Pluralsight course here to help you with that. You will want to ensure this virtual machine has the resource you want to run the container/pods scenarios you’d like to worth with. My configuration is dual vCPU with 10GB of RAM. 

Since we’re running a hypervisor inside a VM, you will need to enable nested virtualization in your virtual machine configuration. Cloud friends, this will not apply to you as most cloud providers do not have this enabled. 

Let’s get started with some prerequisites!

SSH into your virtual machine. I don’t have DNS internally…so I am using the IP address of the virtual machine

demo:~ aen$ ssh aen@192.168.1.69

 
First, install a hypervisor on CentOS, I’m going to use KVM. Installing KVM on RHEL based Linux distributions is most easily done by using a yum group install. This will install all of the packages included in that group for you in one command. Minikube will run inside your virtual machine as a KVM virtual machine. Minikube can use other hypervisors such as Virtual Box and VMware Fusion/Workstation.
 

sudo yum group install “Virtualization Host”

Once the installation is complete, confirm the KVM kernel module is loaded by listing the running kernel modules with lsmod then grepping for the string kvm.

lsmod | grep kvm

kvm_intel             183720  0 

kvm                   578558  1 kvm_intel

irqbypass              13503  1 kvm

Next we’ll install the KVM2 Driver Plugin for minikube

curl -Lo docker-machine-driver-kvm2 https://storage.googleapis.com/minikube/releases/latest/docker-machine-driver-kvm2 \

 && chmod +x docker-machine-driver-kvm2 \

 && sudo cp docker-machine-driver-kvm2 /usr/local/bin/ \

 && rm docker-machine-driver-kvm2

Now, that we have the prep work out of the way, let’s install kubectl. This is the command line utility you will use to interact with your Kubernetes cluster.

sudo yum install kubernetes-client

Next we’ll Install Minikube on our VM

sudo curl -Lo minikube https://storage.googleapis.com/minikube/releases/v0.29.0/minikube-linux-amd64 \

 && chmod +x minikube \

 && sudo cp minikube /usr/local/bin/ \

 && rm minikube

With everything installed, let’s launch minikube – this will download the Minicube ISO, which is a virtual machine containing the minikube cluster.

[aen@k8s1 ~]$ minikube start –vm-driver kvm2

Starting local Kubernetes v1.10.0 cluster…

Starting VM…

Downloading Minikube ISO

 171.87 MB / 171.87 MB [============================================] 100.00% 0s

Getting VM IP address…

Moving files into cluster…

Downloading kubeadm v1.10.0

Downloading kubelet v1.10.0

Finished Downloading kubelet v1.10.0

Finished Downloading kubeadm v1.10.0

Setting up certs…

Connecting to cluster…

Setting up kubeconfig…

Starting cluster components…

Kubectl is now configured to use the cluster.

Loading cached images from config file.

Finally lets check on your cluster configuration to ensure everything is online.

[aen@k8s1 ~]$ kubectl cluster-info

Kubernetes master is running at https://192.168.39.134:8443

CoreDNS is running at https://192.168.39.134:8443/api/v1/proxy/namespaces/kube-system/services/kube-dns

 

To further debug and diagnose cluster problems, use ‘kubectl cluster-info dump’.

With that, you have a functioning Kubernetes cluster inside your virtual machine which you can use for testing and development of your Kubernetes based solutions. 

My Experiences Tech Editing Pro SQL Server on Linux

The Opportunity

Earlier this year I received an email from Jonathan Gennick, an editor at Apress books. The subject of the email was “Tech edit a book” and he asked if I was familiar with SQL Server on Linux. I excitedly replied “yes…I think I’m your guy for this”. In 2017, I had the opportunity to tech edit another book on SQL Server on Linux and had to back out of that project and this was a fantastic second chance to still be able to work on a topic I really want to participate in and help move forward. I replied to Jonathan and asked who the author is…he replied…the author is Bob Ward.

The Author

If you’re active in the SQL Server community you know Bob. Ever present at the major conferences and Principal Architect for on the SQL Server Product Team. Bob has a unique combination of world-class engineering skills and the ability to communicate extremely complex technical details in simple, approachable terms. My first experience watching Bob speak was at SQL Intersection 2014 Fall edition in Las Vegas. At this conference, I saw one of his legendary 3-hour sessions on SQL Server internals. He delivered a session on SQL Server’s memory management system. I remember being amazed by how he took a very complex topic and made it very approachable and understandable to the audience, I even tweeted about it here

The Book

Knowing what an exceptional communicator Bob is and having the opportunity to tech edit a book written by him, this was a no-brainer. I wanted to do this project. We kicked off the project and the first chapter was delivered its title is “Why SQL Server on Linux”. This chapter alone makes the book worth every penny. In this chapter, you’ll learn about the journey of putting SQL Server on Linux. You get first-hand anecdotal stories straight from Bob’s experiences getting SQL Server working on Linux. I remember reading that first chapter and thinking, this is a stellar intro to the book, I literally don’t want to stop reading.

In each chapter, Bob brings his years of experience to help tell the reader what they really need to know about SQL Server on Linux, how it works and how to have a successful SQL Server on Linux deployment. And throughout the book, Bob brings historical anecdotes describing how the various facets of SQL Server got to where they are today. And he also calls out the work of the PMs and members of the product team for the features or innovations they’re responsible for as they’re discussed in the chapters of the book. Bob even takes time to give credit to various members of the SQL Server community and their contributions. This book is as much about the people and journey, as the technology being discussed. 

Getting the Book

The book is still in the final stages of the publishing process and it’s currently available for pre-order online at Apress’ site and also on Amazon. Oh, and at the time of me writing this post, the book is currently number 1 in the “Linux Servers” new releases category and number 18 in the overall “Linux” new releases category on Amazon! Congrats Bob on the book and the successful release!

Bob wrote a blog post about his experiences writing the book, check it out here!
