Building Microsoft SQL Server AlwaysOn Availability Groups – Part 3 – Installation

The Failover Cluster was created so now we can continue with installation of the Microsoft SQL Server.

Create domain accounts for each service

  • Best practice is to have separate account for each service.
    • PowerShell
# Only for TESTING - Not secure because all accounts will have same password.

$users = Import-Csv -Path 'New user in AD.csv'

foreach ($user in $users.UserName)
'Creating user: {0}' -f $user

# Skip -Path to save in default CN=Users.
New-ADUser -Name $user `
-SamAccountName $user -UserPrincipalName ('{0}' -f $user) `
-AccountPassword (ConvertTo-SecureString -String 'Your Unsecure Password' -AsPlainText -Force)  `
-CannotChangePassword:$true -PasswordNeverExpires:$true `
-Path 'CN=Users,DC=ad,DC=contoso,DC=com' `
-PassThru | Enable-ADAccount

Install .NET Framework 3.5 SP1

  • Install .NET 3.5 from the installation media (offline installation) without the need of downloading it from the Microsoft.
  • Command Prompt
dism.exe /Online /Enable-Feature /FeatureName:NetFX3 /All /Source:D:\Sources\sxs /LimitAccess
  • Do not forget to install .NET 3.5 security updates.

Install standalone SQL Server on every node in the cluster

  • Install Microsoft SQL Server on all nodes of you cluster.
  • The processor type should be discovered properly.
  • You need to install stand-alone SQL Server (not the Failover Cluster installation).
  • Choose features that you wish to install.
  • Set the drive letter and the installation directory. It is a good practice to use different volume then C volume. If for any reason the D volume become full then the volume with operating system and with paging file (C or another volume) will not be affected.
  • In the production environment it is recommended to use a named instance.
      • SCVMM0
  • Do not forget to change the drive letter and the directory if you need it.
  • Service Accounts
      • serdb1scvmm0a
      • serdb1scvmm0d
  • Set Startup Type of the services. In a lot of cases you will need to set SQL Server Agent to Automatic startup.
  • Collation – I will user the DB for the System Center products so I will leave it on the default SQL_Latin1_General_CP1_CI_AS.
  • If you can then set only the Windows authentication for the Authentication Mode.
  • Specify SQL Server administrators group
      • dbadmins0
  • Specify the Data Directories
      • Data root directory: D:\Program Files\Microsoft SQL Server\
      • User database directory: D:\Users\SCVMM0\Data
      • User database log directory: D:\Users\SCVMM0\Data
      • Temp DB directory: F:\Temp\Database\SCVMM0\Data
      • Temp DB log directory: G:\Temp\Log\SCVMM0\Data
      • Backup directory: E:\Backup\SCVMM0\Data
  • Enable FILESTREAM if your applications are able to use it.
  • Install
