								</div><h3 id="Introduction">Introduction</h3><div class="text">
							 | 
						||
| 
								 | 
							
								<p>In many production environments, it is very useful to have the capability
							 | 
						||
| 
								 | 
							
								to deploy a new web application, or undeploy an existing one, without having
							 | 
						||
| 
								 | 
							
								to shut down and restart the entire container.  In addition, you can request
							 | 
						||
| 
								 | 
							
								an existing application to reload itself, even if you have not declared it
							 | 
						||
| 
								 | 
							
								to be <code>reloadable</code> in the Tomcat server
							 | 
						||
| 
								 | 
							
								configuration file.</p>
							 | 
						||
| 
								 | 
							
								<p>To support these capabilities, Tomcat includes a web application
							 | 
						||
| 
								 | 
							
								(installed by default on context path <code>/manager</code>) that supports
							 | 
						||
| 
								 | 
							
								the following functions:</p>
							 | 
						||
| 
								 | 
							
								<ul>
							 | 
						||
| 
								 | 
							
								<li>Deploy a new web application from the uploaded contents of a WAR file.</li>
							 | 
						||
| 
								 | 
							
								<li>Deploy a new web application, on a specified context path, from the
							 | 
						||
| 
								 | 
							
								    server file system.</li>
							 | 
						||
| 
								 | 
							
								<li>List the currently deployed web applications, as well as the
							 | 
						||
| 
								 | 
							
								    sessions that are currently active for those web apps.</li>
							 | 
						||
| 
								 | 
							
								<li>Reload an existing web application, to reflect changes in the
							 | 
						||
| 
								 | 
							
								    contents of <code>/WEB-INF/classes</code> or <code>/WEB-INF/lib</code>.
							 | 
						||
| 
								 | 
							
								    </li>
							 | 
						||
| 
								 | 
							
								<li>List the OS and JVM property values.</li>
							 | 
						||
| 
								 | 
							
								<li>List the available global JNDI resources, for use in deployment
							 | 
						||
| 
								 | 
							
								    tools that are preparing <code><ResourceLink></code> elements
							 | 
						||
| 
								 | 
							
								    nested in a <code><Context></code> deployment description.</li>
							 | 
						||
| 
								 | 
							
								<li>Start a stopped application (thus making it available again).</li>
							 | 
						||
| 
								 | 
							
								<li>Stop an existing application (so that it becomes unavailable), but
							 | 
						||
| 
								 | 
							
								    do not undeploy it.</li>
							 | 
						||
| 
								 | 
							
								<li>Undeploy a deployed web application and delete its document base
							 | 
						||
| 
								 | 
							
								    directory (unless it was deployed from file system).</li>
							 | 
						||
| 
								 | 
							
								</ul>
							 | 
						||
| 
								 | 
							
								<p>A default Tomcat installation includes the Manager. To add an instance of the
							 | 
						||
| 
								 | 
							
								Manager web application <code>Context</code> to a new host install the
							 | 
						||
| 
								 | 
							
								<code>manager.xml</code> context configuration file in the
							 | 
						||
| 
								 | 
							
								<code>$CATALINA_BASE/conf/[enginename]/[hostname]</code> folder. Here is an
							 | 
						||
| 
								 | 
							
								example:</p>
							 | 
						||
| 
								 | 
							
								<div class="codeBox"><pre><code><Context privileged="true" antiResourceLocking="false"
							 | 
						||
| 
								 | 
							
								         docBase="${catalina.home}/webapps/manager">
							 | 
						||
| 
								 | 
							
								  <Valve className="org.apache.catalina.valves.RemoteAddrValve"
							 | 
						||
| 
								 | 
							
								         allow="127\.0\.0\.1" />
							 | 
						||
| 
								 | 
							
								</Context></code></pre></div>
							 | 
						||
| 
								 | 
							
								<p>If you have Tomcat configured to support multiple virtual hosts
							 | 
						||
| 
								 | 
							
								(websites) you would need to configure a Manager for each.</p>
							 | 
						||
| 
								 | 
							
								<p>There are three ways to use the <strong>Manager</strong> web application.</p>
							 | 
						||
| 
								 | 
							
								<ul>
							 | 
						||
| 
								 | 
							
								<li>As an application with a user interface you use in your browser.
							 | 
						||
| 
								 | 
							
								Here is an example URL where you can replace <code>localhost</code> with
							 | 
						||
| 
								 | 
							
								your website host name:  <code>http://localhost:8080/manager/html</code> .</li>
							 | 
						||
| 
								 | 
							
								<li>A minimal version using HTTP requests only which is suitable for use
							 | 
						||
| 
								 | 
							
								by scripts setup by system administrators.  Commands are given as part of the
							 | 
						||
| 
								 | 
							
								request URI, and responses are in the form of simple text that can be easily
							 | 
						||
| 
								 | 
							
								parsed and processed.  See <a href="#Supported_Manager_Commands">
							 | 
						||
| 
								 | 
							
								Supported Manager Commands</a> for more information.</li>
							 | 
						||
| 
								 | 
							
								<li>A convenient set of task definitions for the <em>Ant</em>
							 | 
						||
| 
								 | 
							
								(version 1.4 or later) build tool.  See
							 | 
						||
| 
								 | 
							
								<a href="#Executing_Manager_Commands_With_Ant">Executing Manager Commands
							 | 
						||
| 
								 | 
							
								With Ant</a> for more information.</li>
							 | 
						||
| 
								 | 
							
								</ul>
							 | 
						||
| 
								 | 
							
								</div><h3 id="Configuring_Manager_Application_Access">Configuring Manager Application Access</h3><div class="text">
							 | 
						||
| 
								 | 
							
								<p><em>The description below uses the variable name $CATALINA_BASE to refer the
							 | 
						||
| 
								 | 
							
								    base directory against which most relative paths are resolved. If you have
							 | 
						||
| 
								 | 
							
								    not configured Tomcat for multiple instances by setting a CATALINA_BASE
							 | 
						||
| 
								 | 
							
								    directory, then $CATALINA_BASE will be set to the value of $CATALINA_HOME,
							 | 
						||
| 
								 | 
							
								    the directory into which you have installed Tomcat.</em></p>
							 | 
						||
| 
								 | 
							
								<p>It would be quite unsafe to ship Tomcat with default settings that allowed
							 | 
						||
| 
								 | 
							
								anyone on the Internet to execute the Manager application on your server.
							 | 
						||
| 
								 | 
							
								Therefore, the Manager application is shipped with the requirement that anyone
							 | 
						||
| 
								 | 
							
								who attempts to use it must authenticate themselves, using a username and
							 | 
						||
| 
								 | 
							
								password that have one of <strong>manager-xxx</strong> roles associated with
							 | 
						||
| 
								 | 
							
								them (the role name depends on what functionality is required).
							 | 
						||
| 
								 | 
							
								Further, there is no username in the default users file
							 | 
						||
| 
								 | 
							
								(<code>$CATALINA_BASE/conf/tomcat-users.xml</code>) that is assigned to those
							 | 
						||
| 
								 | 
							
								roles.  Therefore, access to the Manager application is completely disabled
							 | 
						||
| 
								 | 
							
								by default.</p>
							 | 
						||
| 
								 | 
							
								<p>You can find the role names in the <code>web.xml</code> file of the Manager
							 | 
						||
| 
								 | 
							
								web application. The available roles are:</p>
							 | 
						||
| 
								 | 
							
								<ul>
							 | 
						||
| 
								 | 
							
								<li><strong>manager-gui</strong> — Access to the HTML interface.</li>
							 | 
						||
| 
								 | 
							
								<li><strong>manager-status</strong> — Access to the "Server Status"
							 | 
						||
| 
								 | 
							
								    page only.</li>
							 | 
						||
| 
								 | 
							
								<li><strong>manager-script</strong> — Access to the tools-friendly
							 | 
						||
| 
								 | 
							
								    plain text interface that is described in this document,
							 | 
						||
| 
								 | 
							
								    and to the "Server Status" page.</li>
							 | 
						||
| 
								 | 
							
								<li><strong>manager-jmx</strong> — Access to JMX proxy interface
							 | 
						||
| 
								 | 
							
								    and to the "Server Status" page.</li>
							 | 
						||
| 
								 | 
							
								</ul>
							 | 
						||
| 
								 | 
							
								<p>The HTML interface is protected against CSRF (Cross-Site Request Forgery)
							 | 
						||
| 
								 | 
							
								attacks, but the text and JMX interfaces cannot be protected. It means that
							 | 
						||
| 
								 | 
							
								users who are allowed access to the text and JMX interfaces have to be cautious
							 | 
						||
| 
								 | 
							
								when accessing the Manager application with a web browser.
							 | 
						||
| 
								 | 
							
								To maintain the CSRF protection:</p>
							 | 
						||
| 
								 | 
							
								<ul>
							 | 
						||
| 
								 | 
							
								<li>If you use web browser to access the Manager application using
							 | 
						||
| 
								 | 
							
								      a user that has either <strong>manager-script</strong> or
							 | 
						||
| 
								 | 
							
								      <strong>manager-jmx</strong> roles (for example for testing
							 | 
						||
| 
								 | 
							
								      the plain text or JMX interfaces), you MUST close all windows
							 | 
						||
| 
								 | 
							
								      of the browser afterwards to terminate the session.
							 | 
						||
| 
								 | 
							
								      If you do not close the browser and visit other sites, you may become
							 | 
						||
| 
								 | 
							
								      victim of a CSRF attack.</li>
							 | 
						||
| 
								 | 
							
								<li>It is recommended to never grant
							 | 
						||
| 
								 | 
							
								      the <strong>manager-script</strong> or <strong>manager-jmx</strong>
							 | 
						||
| 
								 | 
							
								      roles to users that have the <strong>manager-gui</strong> role.</li>
							 | 
						||
| 
								 | 
							
								</ul>
							 | 
						||
| 
								 | 
							
								<p><strong>Note</strong> that JMX proxy interface is effectively low-level root-like
							 | 
						||
| 
								 | 
							
								administrative interface of Tomcat. One can do a lot, if he knows
							 | 
						||
| 
								 | 
							
								what commands to call. You should be cautious when enabling the
							 | 
						||
| 
								 | 
							
								<strong>manager-jmx</strong> role.</p>
							 | 
						||
| 
								 | 
							
								<p>To enable access to the Manager web application, you must either create
							 | 
						||
| 
								 | 
							
								a new username/password combination and associate one of the
							 | 
						||
| 
								 | 
							
								<strong>manager-xxx</strong> roles with it, or add a
							 | 
						||
| 
								 | 
							
								<strong>manager-xxx</strong> role
							 | 
						||
| 
								 | 
							
								to some existing username/password combination.
							 | 
						||
| 
								 | 
							
								As the majority of this document describes the using the text interface, this
							 | 
						||
| 
								 | 
							
								example will use the role name <strong>manager-script</strong>.
							 | 
						||
| 
								 | 
							
								Exactly how the usernames/passwords are configured depends on which
							 | 
						||
| 
								 | 
							
								<a href="/config/realm.html">Realm implementation</a> you are using:</p>

							 | 
						||
| 
								 | 
							
								and port number on which Tomcat is running, <code>{command}</code>
							 | 
						||
| 
								 | 
							
								represents the Manager command you wish to execute, and

						||
| 
								 | 
							
								<code>{parameters}</code> represents the query parameters

| 
								 | 
							
								that are specific to that command.  In the illustrations below, customize
							 | 
						||
| 
								 | 
							
								the host and port appropriately for your installation.</p>
							 | 
						||
| 
								 | 
							
								<p>The commands are usually executed by HTTP GET requests. The
							 | 
						||
| 
								 | 
							
								<code>/deploy</code> command has a form that is executed by an HTTP PUT request.</p>

						||
| 
								 | 
							
								<div class="subsection"><h4 id="Common_Parameters">Common Parameters</h4><div class="text">
							 | 
						||
| 
								 | 
							
								<p>Most commands accept one or more of the following query parameters:</p>
							 | 
						||
| 
								 | 
							
								<ul>
							 | 
						||
| 
								 | 
							
								<li><strong>path</strong> - The context path (including the leading slash)
							 | 
						||
| 
								 | 
							
								    of the web application you are dealing with.  To select the ROOT web
							 | 
						||
| 
								 | 
							
								    application, specify "/".  <strong>NOTE</strong>:
							 | 
						||
| 
								 | 
							
								    It is not possible to perform administrative commands on the
							 | 
						||
| 
								 | 
							
								    Manager application itself.</li>
							 | 
						||
| 
								 | 
							
								<li><strong>version</strong> - The version of this web application as used by
							 | 
						||
| 
								 | 
							
								    the <a href="/config/context.html">parallel deployment</a> feature. If you
							 | 
						||
| 
								 | 
							
								    use parallel deployment wherever a path is required you must specify a

						||
| 
								 | 
							
								    version in addition to the path and it is the combination of path and
							 | 
						||
| 
								 | 
							
								    version that must be unique rather than just the path.</li>
							 | 
						||
| 
								 | 
							
								<li><strong>war</strong> - URL of a web application archive (WAR) file, or
							 | 
						||
| 
								 | 
							
								    pathname of a directory which contains the web application, or a
							 | 
						||
| 
								 | 
							
								    Context configuration ".xml" file.  You can use URLs in any of the

| 
								 | 
							
								    following formats:

						||
| 
								 | 
							
								    <ul>
							 | 
						||
| 
								 | 
							
								<li><strong>file:/absolute/path/to/a/directory</strong> - The absolute
							 | 
						||
| 
								 | 
							
								        path of a directory that contains the unpacked version of a web
							 | 
						||
| 
								 | 
							
								        application.  This directory will be attached to the context path
							 | 
						||
| 
								 | 
							
								        you specify without any changes.</li>
							 | 
						||
| 
								 | 
							
								<li><strong>file:/absolute/path/to/a/webapp.war</strong> - The absolute
							 | 
						||
| 
								 | 
							
								        path of a web application archive (WAR) file.  This is valid
							 | 
						||
| 
								 | 
							
								        <strong>only</strong> for the <code>/deploy</code> command, and is
							 | 
						||
| 
								 | 
							
								        the only acceptable format to that command.</li>
							 | 
						||
| 
								 | 
							
								<li><strong>file:/absolute/path/to/a/context.xml</strong> - The
							 | 
						||
| 
								 | 
							
								        absolute path of a web application Context configuration ".xml"
							 | 
						||
| 
								 | 
							
								        file which contains the Context configuration element.</li>
							 |

								 | 
							
								        application context in the Host's application base directory.</li>
							 | 
						||
| 
								 |

								 | 
							
								        located in the Host's application base directory.</li>
							 | 
						||
|

								</ul></li>
							 | 
						||
|

								<p>Each command will return a response in <code>text/plain</code> format
							 | 
						||
| 
								 | 
							
								(i.e. plain ASCII with no HTML markup), making it easy for both humans and
							 | 
						||
| 
								 | 
							
								programs to read).  The first line of the response will begin with either
							 | 
						||
| 
								 | 
							
								<code>OK</code> or <code>FAIL</code>, indicating whether the requested
							 | 
						||
| 
								 | 
							
								command was successful or not.  In the case of failure, the rest of the first

| 
								 | 
							
								<li><em>Application already exists at path /foo</em>

								 | 
							
								    The JMX Proxy Servlet is a lightweight proxy to get and set the
							 | 
						||
| 
								 | 
							
								    tomcat internals. (Or any class that has been exposed via an MBean)
							 | 
						||
| 
								 | 
							
								    Its usage is not very user friendly but the UI is
							 | 
						||
| 
								 | 
							
								    extremely helpful for integrating command line scripts for monitoring
							 | 
						||
| 
								 | 
							
								    and changing the internals of tomcat. You can do two things with the proxy:
							 | 
						||
| 
								 | 
							
								    get information and set information. For you to really understand the
							 | 
						||
| 
								 | 
							
								    JMX Proxy Servlet, you should have a general understanding of JMX.
							 | 
						||
| 
								 | 
							
								    If you don't know what JMX is, then prepare to be confused.

								    The JXMProxyServlet also supports a "get" command that you can use to

								    fetch the value of a specific MBean's attribute. The general form of

								    If all goes well, then it will say OK, otherwise an error message will

								<p>In addition to the ability to execute Manager commands via HTTP requests,

								 | 
							
								as documented above, Tomcat includes a convenient set of Task definitions
							 |

| 
								 | 
							
								for the <em>Ant</em> (version 1.4 or later) build tool.  In order to use these

							 | 
						||
| 
								 | 
							
								<ul>
							 | 
						||
| 
								 | 
							
								<li>Download the binary distribution of Ant from
							 |

| 
								 | 
							
								    <a href="http://ant.apache.org">http://ant.apache.org</a>.
							 | 
						||
| 
								 | 
							
								    You must use version <strong>1.4</strong> or later.</li>
							 | 
						||
| 
								 | 
							
								<li>Install the Ant distribution in a convenient directory (called
							 | 
						||
| 
								 | 
							
								    ANT_HOME in the remainder of these instructions).</li>
							 | 
						||
| 
								 | 
							
								<li>Add the <code>$ANT_HOME/bin</code> directory to your <code>PATH</code>
							 | 
						||
| 
								 | 
							
								    environment variable.</li>
							 |

| 
								 | 
							
								<li>Configure at least one username/password combination in your Tomcat

								    user database that includes the <code>manager-script</code> role.</li>
							 | 
						||
|

| 
								 | 
							
								<p>To use custom tasks within Ant, you must declare them first with an

								<p>Note: The definition of the resources task via the import above will override
							 | 
						||
| 
								 | 
							
								the resources datatype added in Ant 1.7. If you wish to use the resources
							 | 
						||
| 
								 | 
							
								datatype you will need to use Ant's namespace support to modify
							 | 
						||
| 
								 | 
							
								<code>catalina-tasks.xml</code> to assign the Tomcat tasks to their own
							 | 
						||
| 
								 | 
							
								namespace.</p>
							 | 
						||
| 
								 | 
							
								<p>Now, you can execute commands like <code>ant deploy</code> to deploy the
							 | 
						||
| 
								 | 
							
								application to a running instance of Tomcat, or <code>ant reload</code> to
							 | 
						||
| 
								 | 
							
								tell Tomcat to reload it.  Note also that most of the interesting values in
							 | 
						||
| 
								 | 
							
								this <code>build.xml</code> file are defined as replaceable properties, so
							 | 
						||
| 
								 | 
							
								you can override their values from the command line.  For example, you might
							 | 
						||
| 
								 | 
							
								consider it a security risk to include the real manager password in your
							 | 
						||
| 
								 | 
							
								<code>build.xml</code> file's source code.  To avoid this, omit the password
							 | 
						||
| 
								 | 
							
								property, and specify it from the command line:</p>

								output, unless you are using the <code>append="true"</code> attribute, in which case you will
