      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 presisted 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>
      Note that in case you retreive your users using the
      <code>DataSourceRealm</code>, <code>JDBCRealm</code>, or
      <code>JNDIRealm</code> mechanism, add the appropriate role in the database
      or the directory server respectively.
    </p>

  <section name="Interface Description">
    <p>The interface is divided into six sections:</p>
    <ul>

      <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.
