Set Administrator password for Tomcat

To enable access to the Manager Web application, you must either create a new username/password combination and associate one of the manager roles with it, or add a manager role to some existing username/password combination. To do that:

1. Go to Tomcat installation directory > conf > tomcat-users.xml. Example C:\apache-tomcat-6.0.35\conf]\ tomcat-users.xml Figure1

2. Add the following two lines Figure 2:

<role rolename="manager-gui"/>

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

3. Save it and restart tomcat.

4. This will create a user called admin which used by the individual to log on, with the role of manager-gui

Figure 1 Open tomcat-users.xml

Figure 2 Add the highlighted two lines
