Installing Skype for Business – Part 5

Share this:

Time to finally deploy Skype for Business has come, in this Tutorial we are going to be deploying the Skype for Business Server 2015 bits on the server.


So far in this series we have prepared the Active Directory, DNS infrastructure, deployed the Central Management Store (CMS), but the actual installation of Skype for Business bits hasn’t occurred yet, and that is going to be the focus on this Tutorial, where we will be first installing the Local Configuration Store and then the Skype for Business Server 2015 bits on the server.

In the main page of Skype for Business Server 2015 deployment wizard, click on Install or Update Skype for Business Server System to start the process.


Installing the Local Configuration Store…

Before installing the server bits, we need to install the Local Configuration Store on the server, and even though our infrastructure is simple and it has on the same server the CMS (Central Management Store), the LCS (Local Configuration Store) is a requirement.

The Local Management Store will populate its settings from the CMS as part of the server deployment.

In order to install it, click on Run in the Step 1: Install Local Configuration Store section.


In the first page, leave default settings which is to retrieve the information from the Central Management Store, and click Next.

Note: If the Topology was not published or the current server is not there, then nothing will happen, and that is why is so important to prepare the Topology first.


The process may take a while, wait for the completion of the process and then click Finish.


How the local SQL instance deals with Local Configuration Store and Central management Store?

If you are asking yourself, how the Local/Central Management Store divide the local SQL Server installation when a single Standard Skype for Business Server is deployed, then this section is for you.

The figure below is right after the installation of the Central Management Store (CMS), and the result is a instance called RTC on the local server.


After installing the Local Configuration Store, then a new instance called RTCLOCAL will be created as follows.


Deploying Skype for Business Server 2015…

Time has finally come (I swear that is the last time that I say that), in order to deploy the server bits, click on Run located on the Step 2: Setup or Remove Skype for Business Server Components section.


In the initial page, just click Next.


In the Executing Commands page. It may take a while to process, and during the process we may need to deploy missing updates like the example below, make sure to copy the link location and click on Finish. After that make sure to satisfy all the requirements displayed on the windows and then repeat the steps.


If everything went okay, the results will be similar to the figure below, just click on Finish.


The results on the Deployment Wizard will be Step 1 and Step 2 completed (as shown in the figure below).


Are we ready to start using it? Well, the answer is no, we still need to work on the certificates which is the topic of Tomorrow’s Tutorial. Stay tuned!
