What is the problem with the DBMS (MySQL)?

Question

MySQL

MySQL DBMS suddenly stopped working. Didn't touch anything in it.
Writes an error (in the Go server console):
dial tcp 127.0.0.1:3306: connectex: No connection could be made because the target machine actively refused it.
And even in a DBMS/DB does not allow to come! Yuzayu Denver (works fine) and Adminer.php. At the entrance, it writes this (with localhost and localhost: 3306):

or this:

Text: php_network_getaddresses: getaddrinfo failed: Ýňîň őîńň íĺčçâĺńňĺí.
Previously, the characters did not distort.

What can be wrong? Some kind of PHP error? Or stupidly the DBMS fell off?

Answer 1

3306 port is not listening to any service
localhost does not resolve to 127.0.0.1
Latest version Denver-3 (2 June 2013 ).

Answer 2

It turned out that this is a MySQL #2002 error (it gives it to PHPMyAdmin when trying to connect to the DBMS).
Fixed by reinstalling Denver.
Why the DBMS just flew off is unknown.
