<h2 id="synopsis">Synopsis</h2>
<p>This function will help you to quickly install a SQL Server instance.</p>
<h2 id="description">Description</h2>
<p>This function will help you to quickly install a SQL Server instance on one or many computers.<br />
Some of the things this function will do for you:</p>
<ul>
<li>Add your login as an admin to the new instance</li>
<li>Search for SQL Server installations in the specified file repository</li>
<li>Generate SA password if needed</li>
<li>Install specific features using 'Default' and 'All' templates or cherry-pick the ones you need</li>
<li>Set number of tempdb files based on number of cores (SQL2016+)</li>
<li>Activate .Net 3.5 feature for SQL2012/2014</li>
<li>Restart the machine if needed after the installation is done</li>
</ul>
<p>Fully customizable installation parameters allow you to:</p>
<ul>
<li>Use existing Configuration.ini files for the installation</li>
<li>Define service account credentials using native Powershell syntax</li>
<li>Override any configurations by using -Configuration switch</li>
<li>Change the TCP port after the installation is done</li>
<li>Enable 'Perform volume maintenance tasks' for the SQL Server account</li>
</ul>
<p>Note that the downloaded installation media must be extracted and available to the server where the installation runs.<br />
NOTE: If no ProductID (PID) is found in the configuration files/parameters, Evaluation version is going to be installed.</p>
<p>When using CredSSP authentication, this function will try to configure CredSSP authentication for PowerShell Remoting sessions.<br />
If this is not desired (e.g.: CredSSP authentication is managed externally, or is already configured appropriately,)<br />
it can be disabled by setting the dbatools configuration option 'commands.initialize-credssp.bypass' value to $true.<br />
To be able to configure CredSSP, the command needs to be run in an elevated PowerShell session.</p>

<p> </p>
<h5 id="example-1">Example:  1</h5>
<pre><code>PS C:\&gt; Install-DbaInstance -Version 2017 -Feature All
</code></pre>
<p>Install a default SQL Server instance and run the installation enabling all features with default settings. Automatically generates configuration.ini<br></p>
<h5 id="example-2">Example:  2</h5>
<pre><code>PS C:\&gt; Install-DbaInstance -SqlInstance sql2017\sqlexpress, server01 -Version 2017 -Feature Default
</code></pre>
<p>Install a named SQL Server instance named sqlexpress on sql2017, and a default instance on server01. Automatically generates configuration.ini.<br>
Default features will be installed.<br></p>
<h5 id="example-3">Example:  3</h5>
<pre><code>PS C:\&gt; Install-DbaInstance -Version 2008R2 -SqlInstance sql2017 -ConfigurationFile C:\temp\configuration.ini
</code></pre>
<p>Install a default named SQL Server instance on the remote machine, sql2017 and use the local configuration.ini<br></p>
<h5 id="example-4">Example:  4</h5>
<pre><code>PS C:\&gt; Install-DbaInstance -Version 2017 -InstancePath G:\SQLServer -UpdateSourcePath '\\my\updates'
</code></pre>
<p>Run the installation locally with default settings apart from the application volume, this will be redirected to G:\SQLServer.<br>
The installation procedure would search for SQL Server updates in \my\updates and slipstream them into the installation.<br></p>
<h5 id="example-5">Example:  5</h5>
<pre><code>PS C:\&gt; $svcAcc = Get-Credential MyDomain\SvcSqlServer
PS C:\&gt; Install-DbaInstance -Version 2016 -InstancePath D:\Root -DataPath E: -LogPath L: -PerformVolumeMaintenanceTasks -EngineCredential $svcAcc
</code></pre>
<p>Install SQL Server 2016 instance into D:\Root drive, set default data folder as E: and default logs folder as L:.<br>
Perform volume maintenance tasks permission is granted. MyDomain\SvcSqlServer is used as a service account for SqlServer.<br></p>

<h5 id="authentication">-Authentication</h5>
<p>Chooses an authentication protocol for remote connections.<br />
Allowed values: 'Default', 'Basic', 'Negotiate', 'NegotiateWithImplicitCredential', 'Credssp', 'Digest', 'Kerberos'.<br />
If the protocol fails to establish a connection and explicit -Credentials were used, a failback authentication method would be attempted that configures PSSessionConfiguration<br />
on the remote machine. This method, however, is considered insecure and would, therefore, prompt an additional confirmation when used.<br />
Defaults:</p>
<ul>
<li>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.</li>
<li>Default when -Credential is not specified. Will likely fail if a network path is specified.<br />
For CredSSP see also additional information in DESCRIPTION.<br></li>

<h5 id="configuration">-Configuration</h5>
<p SQLCOLLATION="Latin1_General_BIN">A hashtable with custom configuration items that you want to use during the installation.<br />
Overrides all other parameters.<br />
For example, to define a custom server collation you can use the following parameter:<br />
PS&gt; Install-DbaInstance -Version 2017 -Configuration @<br />
As long as you don't specify the item ACTION, some items are already set by the command, like SQLSYSADMINACCOUNTS or *SVCSTARTUPTYPE.<br />
If you specify the item ACTION, only INSTANCENAME and FEATURES are set based on the corresponding parameters and QUIET is set to True.<br />
You will have to set all other needed items for your specific ACTION.<br />
But this way it is possible to use the command so install a Failover Cluster Instance or even to remove a SQL Server instance.<br />
More information about how to install a Failover Cluster Instance can be found here: <a href="https://github.com/dataplat/dbatools/discussions/7447">https://github.com/dataplat/dbatools/discussions/7447</a><br />
