This commit also renames a lot of Management Server installation files to try to get consistency in the naming of files. It should make it easier to identify which files are for which section.

<title>Install the Database on a Separate Node</title>
|
|
<para>This section describes how to install MySQL on a standalone machine, separate from the Management Server.
|
|
This technique is intended for a deployment that includes several Management Server nodes.
|
|
If you have a single-node Management Server deployment, you will typically use the same node for MySQL.
|
|
See <xref linkend="install-database-on-management-server-node"/>.
