function Install-DbaInstance { <# .SYNOPSIS This function will help you to quickly install a SQL Server instance. .DESCRIPTION This function will help you to quickly install a SQL Server instance on one or many computers. Some of the things this function will do for you: * Add your login as an admin to the new instance * Search for SQL Server installations in the specified file repository * Generate SA password if needed * Install specific features using 'Default' and 'All' templates or cherry-pick the ones you need * Set number of tempdb files based on number of cores (SQL2016+) * Activate .Net 3.5 feature for SQL2012/2014 * Restart the machine if needed after the installation is done Fully customizable installation parameters allow you to: * Use existing Configuration.ini files for the installation * Define service account credentials using native Powershell syntax * Override any configurations by using -Configuration switch * Change the TCP port after the installation is done * Enable 'Perform volume maintenance tasks' for the SQL Server account Note that the dowloaded installation media must be extracted and available to the server where the installation runs. NOTE: If no ProductID (PID) is found in the configuration files/parameters, Evaluation version is going to be installed. .PARAMETER SqlInstance The target computer and, optionally, a new instance name and a port number. Use one of the following generic formats: Server1 Server2\Instance1 Server1\Alpha:1533, Server2\Omega:1566 "ServerName\NewInstanceName,1534" You can also define instance name and port using -InstanceName and -Port parameters. .PARAMETER SaCredential Securely provide the password for the sa account when using mixed mode authentication. .PARAMETER Credential Used when executing installs against remote servers .PARAMETER ConfigurationFile The path to the custom Configuration.ini file. .PARAMETER Configuration A hashtable with custom configuration items that you want to use during the installation. Overrides all other parameters. For example, to define a custom server collation you can use the following parameter: PS> Install-DbaInstance -Version 2017 -Configuration @{ SQLCOLLATION = 'Latin1_General_BIN' } Full list of parameters can be found here: https://docs.microsoft.com/en-us/sql/database-engine/install-windows/install-sql-server-from-the-command-prompt#Install .PARAMETER Authentication Chooses an authentication protocol for remote connections. If the protocol fails to establish a connection Defaults: * CredSSP when -Credential is specified - due to the fact that repository Path is usually a network share and credentials need to be passed to the remote host to avoid the double-hop issue. * Default when -Credential is not specified. Will likely fail if a network path is specified. .PARAMETER Version SQL Server version you wish to install. .PARAMETER InstanceName Name of the SQL Server instance to install. Overrides the instance name specified in -SqlInstance. .PARAMETER Feature Features to install. Templates like "Default" and "All" can be used to setup a predefined set of components. .PARAMETER InstancePath Root folder for instance components. Includes SQL Server logs, system databases, etc. .PARAMETER DataPath Path to the Data folder. .PARAMETER LogPath Path to the Log folder. .PARAMETER TempPath Path to the TempDB folder. .PARAMETER BackupPath Path to the Backup folder. .PARAMETER AdminAccount One or more members of the sysadmin group. Uses UserName from the -Credential parameter if specified, or current Windows user by default. .PARAMETER Port After successful installation, changes SQL Server TCP port to this value. Overrides the port specified in -SqlInstance. .PARAMETER ProductID Product ID, or simply, serial number of your SQL Server installation, which will determine which version to install. If the PID is already built into the installation media, can be ignored. .PARAMETER EngineCredential Service account of the SQL Server Database Engine .PARAMETER AgentCredential Service account of the SQL Server Agent .PARAMETER ASCredential Service account of the Analysis Services .PARAMETER ISCredential Service account of the Integration Services .PARAMETER RSCredential Service account of the Reporting Services .PARAMETER FTCredential Service account of the Full-Text catalog service .PARAMETER PBEngineCredential Service account of the PolyBase service .PARAMETER Path Path to the folder(s) with SQL Server installation media downloaded. It will be scanned recursively for a corresponding setup.exe. Path should be available from the remote server. If a setup.exe file is missing in the repository, the installation will fail. Consider setting the following configuration if you want to omit this parameter: `Set-DbatoolsConfig -Name Path.SQLServerSetup -Value '\\path\to\installations'` .PARAMETER PerformVolumeMaintenanceTasks Allow SQL Server service account to perform Volume Maintenance tasks. .PARAMETER SaveConfiguration Save installation configuration file in a custom location. Will not be preserved otherwise. .PARAMETER Throttle Maximum number of computers updated in parallel. Once reached, the update operations will queue up. Default: 50 .PARAMETER Restart Restart computer automatically if a restart is required before or after the installation. .PARAMETER DotNetPath Path to the .Net 3.5 installation folder (Windows installation media) for offline installations. Might be required for SQL2012/2014 .PARAMETER AuthenticationMode Chooses between Mixed and Windows authentication. .PARAMETER EnableException By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message. This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting. Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch. .PARAMETER WhatIf Shows what would happen if the command were to run. No actions are actually performed. .PARAMETER Confirm Prompts you for confirmation before executing any changing operations within the command. .NOTES Tags: Install Author: Reitse Eskens (@2meterDBA), Kirill Kravtsov (@nvarscar) Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .Example C:\PS> Install-DbaInstance -Version 2017 -Feature All Install a default SQL Server instance and run the installation enabling all features with default settings.
