How to install SharePoint 2013 with controlled names for databases

Are you having a similar name for your adminCentral database : SharePoint_AdminContent_[GUID] ?
If you are looking for more control, this is how you can create databases with "better" names :

1. Launch the SharePoint 2013 Management PowerShell as an Administrator.
2. Type this :
   
   Code:
   

   New-SPConfigurationDatabase -DatabaseName CONFIG_DB_NAME_HERE -DatabaseServer SERVER_NAME_HERE -AdministrationContentDatabaseName ADMIN_DB_NAME_HERE -FarmCredentials (Get-Credential) -Passphrase (ConvertTo-SecureString "TYPE_YOUR_PWD_HERE" -AsPlainText -Force)
   

Notice that you can use this command, only before executing the SharePoint 2013 configuration Wizard, so just after binaries been installed.
During the installation, you'll be asked to launch the wizard and continue the process. You'll have to uncheck the checkbox.
