RabbitMQ failed to log in as guest user. 401 User authorization failed to log in. Handling process:

Create user and password

rabbitmqctl add_user guest guest

2. set the user permissions

rabbitmqctl set_permissions -p / guest ".* " ".* " ".* "

3. Set up user roles

rabbitmqctl set_user_tags guest administrator Detailed explanation: 1. user management

User management includes adding users, deleting users, viewing user lists, and modifying user passwords.

the corresponding command

(1)Add a new user

rabbitmqctl add_user Username Password

(2)delete a user

rabbitmqctl delete_user Username

(3)Change user password

(4)View current user list

rabbitmqctl list_users2. user role

According to personal understanding, user roles can be divided into five categories, super administrator, monitor, policy maker, general manager and others.

(1)super administrator

You can log in to the admin console (with management plugin enabled) to view all information and to manipulate user policies.

(2)monitor (monitor)

Log in to the admin console (with management plugin enabled) and view rabbitmq node related information (number of processes, memory usage, disk usage, etc.)

(3)Policymaker

You can log in to the admin console (with management plugin enabled) and manage policies. However, you cannot view the information about the node (the part identified by the red box in the image above).

Compare this to the administrator, who can see it.

(4)general manager (management)

You can only log in to the admin console (with management plugin enabled), you cannot see node information, and you cannot manage policies.

(5)other

Unable to log on to the admin console, usually ordinary producers and consumers.

Once you understand this, you can assign different roles to different users as needed to manage them on-demand.

The command to set user roles is rabbitmqctl set_user_tags User Tag

User is the user name, Tag is the role name (corresponding to administrator, monitoring, policymaker, management, or other custom name above).

Multiple roles can also be assigned to the same user, for example

rabbitmqctl set_user_tags hncscwc monitoring policymaker3. user rights

User permissions refer to the user's operation permissions on exchange and queue, including configuration permissions, read and write permissions. Configuration permissions affect exchange, queue declaration and deletion. Read and write permissions affect fetching messages from queues, sending messages to exchanges, and binding queues to exchanges.

For example, binding queue to an exchange requires writeable access to queue and readable access to exchange; sending messages to exchange requires writeable access to exchange; fetching data from queue requires readable access to queue. For details, please refer to the section "How permissions work" in the official documentation.

The relevant commands are:

(1)set the user permissions

rabbitmqctl set_permissions -p VHostPath User ConfP WriteP ReadP

(2)View (specify hostpath) all user permissions information

rabbitmqctl list_permissions [-p VHostPath]

(3)View permission information for a specified user

rabbitmqctl list_user_permissions User

(4)Clear user's permission information

rabbitmqctl clear_permissions [-p VHostPath] User Thank you for reading, the above is "how to solve RabbitMQ can not use guest user login problem" content, after the study of this article, I believe everyone on how to solve RabbitMQ can not use guest user login problem This problem has a deeper understanding, the specific use of the situation also needs to be verified by practice.
