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>
</div><h3 id="Configuring_Manager_Application_Access">Configuring Manager Application Access
</h3><div class="text">
<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>
<div class="codeBox"><pre><code><user username="test" password="chang3m3N#w" roles="admin-gui"/
></code></pre></div>
<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>
</div><h3 id="Interface_Description">Interface Description

<p>The interface is divided into six sections:

, 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>
</div><h3 id="Message">Message
</h3><div class="text">
<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.

application. Note that you user must have sufficient permissions to access
the application.
</li>
</ul>
</div><h3 id="Host_Name">Host Name
</h3><div class="text">
<p>The Host name section contains a list of currently-configured virtual host

<p>The Persist Configuration section enables you to persist your current
configuration into the

</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>
<div class="codeBox"><pre><code><Listener className="org.apache.catalina.storeconfig.StoreConfigLifecycleListener"/
></code></pre></div>
<p>After you configure the listener, click
