更新后无法登录tomcat管理器

Question

After a system update, I can no longer log in in tomcat. It was working before the update, but it's not working any longer. Not entirely sure what happened.

OS: Arch linux

Java version: openjdk 1.8.0_25

Current Tomcat version: 8.0.15

tomcat-users.xml:

<?xml version='1.0' encoding='utf-8'?>

  <user username="manager" password="manager" roles="manager-gui,manager-script,manager-jmx,manager-status"/>
  <user username="admin" password="admin" roles="admin-gui"/>
</tomcat-users>

manager/manager still gives me unauthorized. Any ideas why?

Also, is there a way to see a list of all the users loaded by the tomcat instance?

Answer 1

There are a lot of possible causes for this:

• Have you restarted tomcat after editing the file?
• Are you sure that the tomcat user has sufficient permissions for the config file
• Try adding the admin-gui role for the manager user
