Create SQL Server Alias using PowerShell

As per SharePoint best practices for SQL Server, SQL Alias needs to be created on all SharePoint Servers in the farm. Creating SQL Alias for SharePoint through UI, is already explained in my another post: Create SQL Server Alias for SharePoint , and here is the PowerShell version of creating SQL Server Alias.

#Name of your SQL Server Alias
$AliasName = "SP13_PROD_SQL"

# Actual SQL Server Name
$SQLServerName = "G1VSP13-SQLC001" 

#TCP Port
$Port = "1433"

#These are the two Registry locations for the SQL Alias 
$x86 = "HKLM:\Software\Microsoft\MSSQLServer\Client\ConnectTo"
$x64 = "HKLM:\Software\Wow6432Node\Microsoft\MSSQLServer\Client\ConnectTo"

#if the ConnectTo key doesn't exists, create it.
if ((test-path -path $x86) -ne $True)
{
    New-Item $x86
}

if ((test-path -path $x64) -ne $True)
{
    New-Item $x64
}

#Define SQL Alias 
$TCPAliasName = "DBMSSOCN,$SQLServerName,$Port"

#Create TCP/IP Aliases
New-ItemProperty -Path $x86 -Name $AliasName -PropertyType String -Value $TCPAliasName
New-ItemProperty -Path $x64 -Name $AliasName -PropertyType String -Value $TCPAliasName

finally, open these two executables to verify:

• C:\Windows\System32\cliconfg.exe
• C:\Windows\SysWOW64\cliconfg.exe
