Open the Tomcat management interface and tomcat Management Interface

Open the Tomcat management interface and tomcat Management Interface
You encountered the following problems when managing tomcat:


1. At the beginning, a user name and password are required. I do not know what the user name and password are, but I did not enter any correct information.


Solution:


Add your own user conf folder in the tomcat-users.xml in the format


The default value is commented out, which mainly takes into account the security of the server. If it is a local test, remove the following comment, restart the server, and then enter


<Role rolename = "tomcat"/>


<Role rolename = "role1"/>


<User username = "tomcat" password = "tomcat" roles = "tomcat"/>


<User username = "both" password = "tomcat" roles = "tomcat, role1"/>


<User username = "role1" password = "tomcat" roles = "role1"/>


The user and password are clear at a glance.


 


 


2. After Entering the manager interface, the 403 Access Denied is displayed.


Solution:


See this passage in the conf/tomcat-users.xml file:


NOTE: By default, no user is logged in the "manager-gui" role required


To operate the "/manager/html" web application. If you want to use this app,


You must define such a user-the username and password are arbitrary.


To ensure security, tomcat does not have the manager-gui management permission by default.


You need to add the management permission (role) on your own ).


You need to add such permissions (roles)


<Role rolename = "manager-gui"/>


And then add it to the user name.


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


So OK.
