Introduction

The Tomcat Host Manager 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:

  • Virtual Hosting How-To for more information about virtual hosting.
  • The Host Container for more information about the underlying xml configuration of virtual hosts and description of attributes.

The Tomcat Host Manager application is a part of Tomcat installation, by default available using the following context: /host-manager. You can use the host manager in the following ways:

  • Utilizing the graphical user interface, accessible at: {server}:{port}/host-manager/html.
  • Utilizing a set of minimal HTTP requests suitable for scripting. You can access this mode at: {server}:{port}/host-manager/text.

Both ways enable you to add, remove, start, and stop virtual hosts. Changes may be persisted by using the persist command. This document focuses on the text interface. For further information about the graphical interface, see Host Manager App -- HTML Interface.

Configuring Manager Application Access

The description below uses $CATALINA_HOME to refer the base Tomcat directory. It is the directory in which you installed Tomcat, for example C:tomcat8, or /usr/share/tomcat8.

The Host Manager application requires a user with one of the following roles:

  • admin-gui - use this role for the graphical web interface.
  • admin-script - use this role for the scripting web interface.

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 ${CATALINA_BASE}/conf/tomcat-users.xml and enter the following:

No further settings is needed. When you now access {server}:{port}/host-manager/text/${COMMAND},you are able to log in with the created credentials. For example:

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.

List of Commands

The following commands are supported:

  • list
  • add
  • remove
  • start
  • stop
  • persist

In the following subsections, the username and password is assumed to be test:test. For your environment, use credentials created in the previous sections.

List command

Use the list command to see the available virtual hosts on your Tomcat instance.

Example command:

curl -u test:test http://localhost:8080/host-manager/text/list

Example response:

Add command

Use the add command to add a new virtual host. Parameters used for the add command:

  • String name: Name of the virtual host. REQUIRED
  • String aliases: Aliases for your virtual host.
  • String appBase: Base path for the application that will be served by this virtual host. Provide relative or absolute path.
  • Boolean manager: If true, the Manager app is added to the virtual host. You can access it with the /manager context.
  • Boolean autoDeploy: If true, Tomcat automatically redeploys applications placed in the appBase directory.
  • Boolean deployOnStartup: If true, Tomcat automatically deploys applications placed in the appBase directory on startup.
  • Boolean deployXML: If true, the /META-INF/context.xml file is read and used by Tomcat.
  • Boolean copyXML: If true, Tomcat copies /META-INF/context.xml file and uses the original copy regardless of updates to the application's /META-INF/context.xml file.

Example command:

Example response:

Remove command

Use the remove command to remove a virtual host. Parameters used for the remove command:

  • String name: Name of the virtual host to be removed. REQUIRED

Example command:

Example response:

Start command

Use the start command to start a virtual host. Parameters used for the start command:

Http Localhost 8080 Tomcat
  • String name: Name of the virtual host to be started. REQUIRED

Example command:

Example response:

Stop command

Use the stop command to stop a virtual host. Parameters used for the stop command:

  • String name: Name of the virtual host to be stopped. REQUIRED

Example command:

Example response:

Persist command

Use the persist command to persist a virtual host into server.xml. Parameters used for the persist command:

  • String name: Name of the virtual host to be persist. REQUIRED

This functionality is disabled by default. To enable this option, you must configure the StoreConfigLifecycleListener listener first. To do so, add the following listener to your server.xml:

Example manual entry:

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.

It would be quite unsafe to ship Tomcat with default settings that allowedanyone on the Internet to execute the Manager application on your server.Therefore, the Manager application is shipped with the requirement that anyonewho attempts to use it must authenticate themselves, using a username andpassword that have one of manager-xxx roles associated withthem (the role name depends on what functionality is required).Further, there is no username in the default users file($CATALINA_BASE/conf/tomcat-users.xml) that is assigned to thoseroles. Therefore, access to the Manager application is completely disabledby default.

You can find the role names in the web.xml file of the Managerweb application. The available roles are:

  • manager-gui — Access to the HTML interface.
  • manager-status — Access to the 'Server Status' page only.
  • manager-script — Access to the tools-friendly plain text interface that is described in this document, and to the 'Server Status' page.
  • manager-jmx — Access to JMX proxy interface and to the 'Server Status' page.

The HTML interface is protected against CSRF (Cross-Site Request Forgery)attacks, but the text and JMX interfaces cannot be protected. It means thatusers who are allowed access to the text and JMX interfaces have to be cautiouswhen accessing the Manager application with a web browser.To maintain the CSRF protection:

Http Localhost 8080 Tomcat Download

  • If you use web browser to access the Manager application using a user that has either manager-script or manager-jmx 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.
  • It is recommended to never grant the manager-script or manager-jmx roles to users that have the manager-gui role.

Note that JMX proxy interface is effectively low-level root-likeadministrative interface of Tomcat. One can do a lot, if he knowswhat commands to call. You should be cautious when enabling themanager-jmx role.

To enable access to the Manager web application, you must either createa new username/password combination and associate one of themanager-xxx roles with it, or add amanager-xxx roleto some existing username/password combination.As the majority of this document describes the using the text interface, thisexample will use the role name manager-script.Exactly how the usernames/passwords are configured depends on whichRealm implementation you are using:

  • UserDatabaseRealm plus MemoryUserDatabase, or MemoryRealm — The UserDatabaseRealm and MemoryUserDatabase are configured in the default $CATALINA_BASE/conf/server.xml. Both MemoryUserDatabase and MemoryRealm read an XML-format file by default stored at $CATALINA_BASE/conf/tomcat-users.xml, which can be edited with any text editor. This file contains an XML <user> for each individual user, which might look something like this: which defines the username and password used by this individual to log on, and the role names he or she is associated with. You can add the manager-script role to the comma-delimited roles attribute for one or more existing users, and/or create new users with that assigned role.
  • DataSourceRealm or JDBCRealm — Your user and role information is stored in a database accessed via JDBC. Add the manager-script role to one or more existing users, and/or create one or more new users with this role assigned, following the standard procedures for your environment.
  • JNDIRealm — Your user and role information is stored in a directory server accessed via LDAP. Add the manager-script role to one or more existing users, and/or create one or more new users with this role assigned, following the standard procedures for your environment.

The first time you attempt to issue one of the Manager commandsdescribed in the next section, you will be challenged to log on usingBASIC authentication. The username and password you enter do not matter,as long as they identify a valid user in the users database who possessesthe role manager-script.

Authorization Required For Localhost 8080

In addition to the password restrictions, access to the Manager webapplication can be restricted by the remote IP address or hostby adding a RemoteAddrValve or RemoteHostValve.See valves documentationfor details. Here isan example of restricting access to the localhost by IP address:
