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 are not persisted to the Tomcat configuraiton files. If you want your settings to be persistent, you must write them into the server.xml configuration file manually. For full documentation about the configuration, see The Host Container. 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 `$CATALINA_HOME` to refer the base Tomcat directory. It is the directory in which you installed Tomcat, for example `C:\tomcat7`, or `/usr/share/tomcat7`. The Host Manager application requires a user with one of the following roles: `admin-gui` - use this role for the graphical web interface. `admin-script` - use this role for the scripting web interface. To enable access to the text interface of the Host Manager application, either grant your Tomcat user the appropriate role, or create a new one with the correct role. For example, open `${CATALINA_BASE}/conf/tomcat-users.xml` and enter the following:
>     <user username="test" password="chang3m3N#w" roles="admin-script"/>
> 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:
>     $ curl -u ${USERNAME}:${PASSWORD} http://localhost:8080/host-manager/text/list
>     OK - Listed hosts
>     localhost:
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 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:
> >     OK - Listed hosts
> >     localhost:
> 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. Available only for Tomcat 8 and newer. Example command:
> >     curl -u test:test http://localhost:8080/host-manager/text/add?name=www.awesomeserver.com&aliases=awesomeserver.com&appBase/mnt/appDir&deployOnStartup=true
> > Example response:
> >     add: Adding host [www.awesomeserver.com]
> 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:
> >     curl -u test:test http://localhost:8080/host-manager/text/remove?name=www.awesomeserver.com
> > Example response:
> >     remove: Removing host [www.awesomeserver.com]
> Start command
> > Use the start command to start a virtual host. Parameters used for the start command: String name: Name of the virtual host to be started. REQUIRED Example command:
> >     curl -u test:test http://localhost:8080/host-manager/text/start?name=www.awesomeserver.com
> > Example response:
> >     OK - Host www.awesomeserver.com started
> 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:
> >     curl -u test:test http://localhost:8080/host-manager/text/stop?name=www.awesomeserver.com
> > Example response:
> >     OK - Host www.awesomeserver.com stopped
