How to reset admin password in Tomcat?

Question

I want to use the status manager on my local installation of Tomcat 7 but it asks for a password and I can't recall what it is. How do I reset it without reinstalling?

Answer 1

You'll want to look at your conf\tomcat-users.xml file. Note, as it is says in that file you'll need to have a user with the role "manager-gui" to use those tools.

So the following line would work:

<user username="tomcat" password="tomcat" roles="manager-gui"/>

Answer 2

Look in the /etc/tomcat7/server.xml file. The password should be visible after the keystorepass tag.

You can test it using the list command like this:

keytool -list -v -keystore .keystore
