HowTo Create SPFarm (SharePoint Farm) with Powershell

After binary installation of SharePoint do not run configuration wizard to build your farm.
Try instead this simple PowerShell script in order to create a clean Farm with Central Administration deployed an SQL Server database without GUID (replace italic information with your environment).
Run this script within SharePoint Management Shell with administrative permissions.

# Service accounts
$DOMAIN = "yourdomain"
$accounts = @{}
$accounts.Add("Farm", @{"username" = ($DOMAIN + "\yourfarmaccount"); "password" = "yourfarmaccountpassword"})

Foreach ($account in $accounts.keys) {
    $accounts.$account.Add(`
    "Credential", `
    (New-Object System.Management.Automation.PsCredential $accounts.$account.username, `
    (ConvertTo-SecureString -String $accounts.$account.password -AsPlainText -Force)))
}

# Farm configuration

$config_Passphrase = "yourpassphrase"
$s_config_Passphrase = (ConvertTo-SecureString -String $config_passphrase -AsPlainText -force)

$server_DB = "SQLSERVERALIAS"
$db_Config = "SP2013_ConfigDb"
$db_CentralAdmin = "SP2013_Content_CentralAdministration"

$ca_port = 2013
$ca_AuthProvider = "NTLM"
