<ol>
<li><p>Install Microsoft SQLServer</p></li>
<li><p>Create a druid database and user</p></li>
</ol>
<p>Create the druid user</p>
<ul>
<li>Microsoft SQL Server Management Studio - Security - Logins - New Login...</li>
<li>Create a druid user, enter <code>diurd</code> when prompted for the password.</li>
</ul>
<p>Create a druid database owned by the user we just created</p>
<ul>
<li>Databases - New Database</li>
<li>Database Name: druid, Owner: druid</li>
</ul>
<ol start="3">
<li>Add the Microsoft JDBC library to the Druid classpath</li>
</ol>
<ul>
<li>To ensure the com.microsoft.sqlserver.jdbc.SQLServerDriver class is loaded you will have to add the appropriate Microsoft JDBC library (sqljdbc*.jar) to the Druid classpath.</li>
<li>For instance, if all jar files in your &quot;druid/lib&quot; directory are automatically added to your Druid classpath, then manually download the Microsoft JDBC drivers from ( <a href="https://www.microsoft.com/en-ca/download/details.aspx?id=11774">https://www.microsoft.com/en-ca/download/details.aspx?id=11774</a>) and drop it into my druid/lib directory.</li>
</ul>
<ol start="4">
<li>Configure your Druid metadata storage extension:</li>
</ol>
<p>Add the following parameters to your Druid configuration, replacing <code>&lt;host&gt;</code>
with the location (host name and port) of the database.</p>
