Answer 1

Update the 'apache-tomcat-8.5.5\conf\tomcat-users.xml file. uncomment the roles and add/replace the following line.and restart server

tomcat-users.xml file

<role rolename="admin"/>
<role rolename="admin-gui"/>
<role rolename="manager-gui"/>
<user username="admin" password="admin" roles="standard,manager,admin,manager-gui,manager-script"/>

Answer 2

Use something like this to update your tomcat users.

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

Tomcat users file is located inside conf folder of tomcat installation. To find the path of catalina_base you can use the command: ps aux | grep catalina You can find one of the values -Dcatalina.base=/usr/local/Cellar/tomcat/9.0.37/libexec

Most Important:

Don't forget to remove the comment lines from the tomcat-users.xml just before the start of the roles. <!-- -->

Answer 3

Well if you are using Netbeans in Linux, then you should look for the tomcat-user.xml in

/home/Username/.netbeans/8.0/apache-tomcat-8.0.3.0_base/conf

(its called Catalina Base and is often hidden) instead of the Apache installation directory.

open tomcat-user.xml inside that folder, uncomment the user and roles and add/replace the following line.

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

restart the server . That's all

Answer 4

One simple way to check your changes to that file in Tomcat 8 + is to open a browser to: http://localhost:8080/manager/text/list

Answer 5

I case of tomcat 7 the role has changed from manager to manager-gui so set it as below in the tomcat-user.xml file.

Answer 6

You will find the tomcat-users.xml in \Users\<Name>\AppData\Roaming\Netbeans\. It exists at least twice on your machine, depending on the number of Tomcat installations you have.
