<section name="Introduction">
<p>
The <strong>Tomcat Host Manager</strong> application enables you to create,
delete, and otherwise manage virtual hosts within Tomcat. This how-to guide
is best accompanied by the following pieces of documentation:
</p>
<ul>
<li>
<a href="virtual-hosting-howto.html">Virtual Hosting How-To</a> for more
information about virtual hosting.
</li>
<li>
<a href="config/host.html">The Host Container</a> for more information
about the underlying xml configuration of virtual hosts and description
of attributes.
</li>
</ul>
<p>
The <strong>Tomcat Host Manager</strong> application is a part of
Tomcat installation, by default available using the following
context: <code>/host-manager</code>. You can use the host manager in the
following ways:
</p>
<ul>
<li>
Utilizing the graphical user interface, accessible at:
<code>{server}:{port}/host-manager/html</code>.
</li>
<li>
Utilizing a set of minimal HTTP requests suitable for scripting.
You can access this mode at:
<code>{server}:{port}/host-manager/text</code>.
</li>
</ul>
<p>
Both ways enable you to add, remove, start, and stop virtual hosts. Changes
may be persisted by using the <code>persist</code> command. This document
focuses on the text interface. For further information about the graphical
interface, see
<a href="html-host-manager-howto.html">Host Manager App -- HTML Interface</a>.
</p>
</section>
<section name="Configuring Manager Application Access">
<p><em>The description below uses <code>$CATALINA_HOME</code> to refer the
base Tomcat directory. It is the directory in which you installed
Tomcat, for example <code>C:\tomcat9</code>, or
<code>/usr/share/tomcat9</code>.</em></p>
<p>
The Host Manager application requires a user with one of the following
roles:
</p>
<ul>
<li>
<code>admin-gui</code> - use this role for the graphical web interface.
</li>
<li>
<code>admin-script</code> - use this role for the scripting web interface.
</li>
</ul>
<p>
To enable access to the text interface of the Host Manager application,
either grant your Tomcat user the appropriate role, or create a new one with
the correct role. For example, open
<code>${CATALINA_BASE}/conf/tomcat-users.xml</code> and enter the following:
</p>
<source><![CDATA[<user username="test" password="chang3m3N#w" roles="admin-script"/>]]></source>
<p>
No further settings is needed. When you now access
<code>{server}:{port}/host-manager/text/${COMMAND}</code>,you are able to
log in with the created credentials. For example:
<source>$ curl -u ${USERNAME}:${PASSWORD} http://localhost:8080/host-manager/text/list
OK - Listed hosts
localhost:</source>
</p>
<p>
If you are using a different realm you will need to add the necessary role
to the appropriate user(s) using the standard user management tools for that
realm.
</p>
</section>
