How to access Tomcat Manager Print

  • 38

Tomcat manager that comes with our Java hosting provides a few tools to help manage your webapps such as deploying new apps and checking status.

Tomcat versions up to version 6

For Tomcat 6 all you need to do is configure your tomcat/conf/tomcat-users.xml with the following:

<?xml version="1.0" encoding="UTF-8"?>

<role rolename="manager"/>
<user username="SOMEUSER" password="YOURPASS" roles="manager"/>

Then restart tomcat and access manager in browser: http://yourdomain.com/manager/html

Tomcat versions 7 and up.

As of Tomcat 7 some things changed to increase tomcat security. When editing the tomcat-users.xml file you need to use existing file and leave the tomcat-users xmlns information as is and simply add:

<?xml version="1.0" encoding="UTF-8"?>
<tomcat-users xmlns="http://tomcat.apache.org/xml"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="http://tomcat.apache.org/xml tomcat-users.xsd"
   version="1.0">
<role rolename="manager-gui"/>
<user username="SOMEUSER" password="YOURPASS" roles="manager-gui"/>

Please note that manager is now manager-gui instead of just manager. There are several different manager types:

  • manager-gui
  • manager-script
  • manager-status
  • manager-jmx

Last step - Allowing Access

By default the Host Manager is only accessible from a browser running on the same machine as Tomcat. If you wish to modify this restriction, you'll need to edit tomcat/webapps/manager/META-INF/context.xml to allow all ips or just yours.

Below configuration is for allowing all IPs to access the manager:

Replace

allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1"  

with

allow=".*"

Example:

<Context antiResourceLocking="false" privileged="true" >
<Valve className="org.apache.catalina.valves.RemoteAddrValve"
 allow=".*" />
</Context>

Finally - restart tomcat and then navigate to yourdomain.com/manager/html

For more information please see the apache tomcat documentation: http://tomcat.apache.org/tomcat-8.5-doc/manager-howto.html
