In this guide I will continue the installation of the SQL 2012 Mirroring cluster which I will use for my Lync 2013 High Availability installation.
You can see the first part here
When using an SQL mirroring cluster you will need a witness server – This is how to install that.
The specs for my witness server is:
- 1 x CPU
- 4 GB RAM
- 100 GB Disk
- Windows Server 2012
Download SQL 2012 Express from Microsoft here: http://www.microsoft.com/en-us/download/details.aspx?id=29062
Double click on the installation file
Choose “New SQL Server….”
Read all the license terms before you accept it and Select Next
Choose Default and Select Next
Select Mixed mode and type a strong SA password. You should also add administrators or even better administrative groups, which must be able to manage the server.
Continue the last screens and wait for the installation to complete.
When the installation is finished you should go to windowsupdate and update both windows and sql server with the latest servicepacks and fixes.
A couple of reboots is normally reqiured.
Next we will create a share on the witness server, which the mirroring cluster will use as well.
Create it on the C: drive, and name it something use full like LyncMirroring
Right click on the new folder and select Properties
Click on Advanced Sharing, and the give it a share name
Click on Permissions and give Everyone Full Control
Click OK twice and select the security fane
Add the two SQL cluster nodes computer account to the permissions and give them full control
Press OK to save the permissions and then close
You should now a two SQL 2012 mirroring servers and a witness server.
In the next guide we will be looking at configuering the SQL servers, before we can use it in Lync 2013.
