How to access the Wildfly admin panel?

Question

Java

Faced such a problem. Until recently, the wildfly admin panel started up without problems, but now, when accessing localhost:9990 , the following panel falls out:

It's not entirely clear why it doesn't let me into the admin panel + what kind of interface? I tried to add, but it comes out like this:

I am authorized. The server is running. There is nothing criminal in the logs.
When accessing 127.0.0.1:9990/management I get:
{
"outcome" : "failed",
"failure-description" : "WFLYCTL0313: Unauthorized to execute operation 'read-resource' for resource '[]' - \"WFLYCTL0332: Permission denied\"",
"rolled-back" : true
}

Answer 1

The problem was with permissions. WildFly, unlike JBoss, supports 2 schemes for ensuring user rights in the admin panel:
- Simple - similar to JBoss. Any admin has unlimited rights.
- RBAC (Role Based Access Control) - allows, respectively, to differentiate access to the admin panel.
By default, when installing the server, the access parameter is set to Simple and is located here:
{wildfly}\standalone\configuration\standalone.xml
{wildfly}\domain\configuration\domain.xml

<management>
  ...
    <access-control provider="simple">
        <role-mapping>
            <role name="SuperUser">
                <include>
                    <user name="$local"/>
                </include>
            </role>
        </role-mapping>
    </access-control>
</management>

The problem is in the provider parameter - I had the value "rbac". It needs to be changed to simple.

Create another user. What is the problem?
