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>
<li>
<a href="host-manager-howto.html">Host Manager App -- Text Interface</a>
for full description of the commands.
</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 HTML interface. For further information about the
graphical interface, see
<a href="host-manager-howto.html">Host Manager App -- Text Interface</a>.
</p>
</section>
<section name="Configuring Manager Application Access">
<p><em>The description below uses <code>$CATALINA_HOME</code> to refer the
base Tomcat directory. It is the directory in which you installed
Tomcat, for example <code>C:\tomcat9</code>, or
<code>/usr/share/tomcat9</code>.</em></p>
<p>
The Host Manager application requires a user with one of the following
roles:
</p>
<ul>
<li>
<code>admin-gui</code> - use this role for the graphical web interface.
</li>
<li>
<code>admin-script</code> - use this role for the scripting web interface.
</li>
</ul>
<p>
To enable access to the HTML interface of the Host Manager application,
either grant your Tomcat user the appropriate role, or create a new one with
the correct role. For example, open
<code>${CATALINA_BASE}/conf/tomcat-users.xml</code> and enter the following:
</p>
<source><![CDATA[<user username="test" password="chang3m3N#w" roles="admin-gui"/>]]></source>
<p>
No further settings is needed. When you now access
<code>{server}:{port}/host-manager/html</code>,you are able to
log in with the created credentials.
</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>
<section name="Interface Description">
<p>The interface is divided into six sections:</p>
<ul>
<li><strong>Message</strong> - Displays success and failure messages.</li>
<li><strong>Host Manager</strong> - Provides basic Host Manager operations
, like list and help.</li>
<li><strong>Host name</strong> - Provides a list of virtual Host Names and
enables you to operate them. </li>
<li><strong>Add Virtual Host</strong> - Enables you to add a new Virtual
Host.</li>
<li><strong>Persist configuration</strong> - Enables you to persist your
current Virtual Hosts.</li>
<li><strong>Server Information</strong> - Information about the Tomcat
server.</li>
</ul>
</section>
<section name="Message">
<p>
Displays information about the success or failure of the last Host Manager
command you performed:
</p>
<ul>
<li>Success: <strong>OK</strong> is displayed
and may be followed by a success message.</li>
<li>Failure: <strong>FAIL</strong>
is displayed followed by an error message.</li>
</ul>
<p>
Note that the console of your Tomcat server may reveal more information
about each command.
</p>
</section>
<section name="Host Manager">
<p>The Host Manager section enables you to:</p>
<ul>
<li><strong>List Virtual Hosts</strong> - Refresh a list of
currently-configured virtual hosts.</li>
<li><strong>HTML Host Manager Help</strong> - A documentation link.</li>
<li><strong>Host Manager Help</strong> - A documentation link.</li>
<li><strong>Server Status</strong> - A link to the <strong>Manager</strong>
application. Note that you user must have sufficient permissions to access
the application.</li>
</ul>
</section>
<section name="Host Name">
<p>The Host name section contains a list of currently-configured virtual host
names. It enables you to:</p>
<ul>
<li>View the host names</li>
<li>View the host name aliases</li>
<li>Perform basic commands, that is <strong>start</strong>,
<strong>stop</strong>, and <strong>remove</strong>.</li>
</ul>
</section>
<section name="Add Virtual Host">
<p>The Add Virtual Host section enables you to add a virtual host using a
graphical interface. For a description of each property, see the
<a href="host-manager-howto.html">Host Manager App -- Text Interface</a>
documentation. Note that any configuration added via this interface is
non-persistent.</p>
</section>
<section name="Persist Configuration">
<p>The Persist Configuration section enables you to persist your current
configuration into the <i>server.xml</i> file.</p>
<p> This functionality is disabled by default. To enable this option, you must
configure the <code>StoreConfigLifecycleListener</code> listener first.
To do so, add the following listener to your <i>server.xml</i>:</p>
<source><![CDATA[<Listener className="org.apache.catalina.storeconfig.StoreConfigLifecycleListener"/>]]></source>
<p>After you configure the listener, click <strong>All</strong> to make your
configuration persistent.</p>
</section>
<section name="Server Information">
<p>
Provides a basic information about the currently-running Tomcat instance,
the JVM, and the underlying operating system.
