Why does not want to connect to the MySQL database?

Question

MySQL

Please help me with connection problem. There is a VPS, a MySQL database is deployed on it, a user userdevel is created with a password of 0000 and full rights to the dbdevel database. When connecting to the database via the console, the connection is successful:
mysql -u userdevel -p
On the same server, the Apache + Passenger bundle is deployed, a site has been created in development mode for online debugging of the deployed application:

# /etc/apache2/sites-available/devel-website.conf
<VirtualHost *:80> 
...
    PassengerAppEnv development 
...
</VirtualHost>

The Ruby on Rails project was copied to the folder, logins and passwords for connection are specified in the config/database.yml file:

default: &default
  adapter: mysql2
  pool: 5
  timeout: 5000
  host: 127.0.0.1
  password: 0000
  encoding: utf8

development:
  <<: *default
  database: userdevel
  username: dbdevel

(I’ll say right away: replacing 127.0.0.1 with localhost in the host line did not help)
But when I try to open the Action Controller site, I get an error:

Access denied for user 'userdevel'@'localhost' (using password: YES)

I repeat, this user (login-password combination) connects to mysql through the console without any problems.
Here is the table of users from the database:

mysql> select user,host from mysql.user;
+------------------+-----------+
| user             | host      |
+------------------+-----------+
| userdevel        | %         |
| debian-sys-maint | localhost |
| mysql.sys        | localhost |
| root             | localhost |
| userdevel        | localhost |
| usertest         | localhost |
| userwork         | localhost |
+------------------+-----------+
7 rows in set (0.00 sec)

What did I do wrong? Tell me please.

Answer 1

and for "userdevel" the rights are all given?

Answer 2

In the database, [email protected] and [email protected] are different users. You are explicitly told that
"Access denied for user 'userdevel'@'localhost' (using password: YES)"
That is, either there is no such user, or the password is different. Check the list of users and add rights to the corresponding user.
