I installed mysql utilities on my ubuntu server today, so I could use mysqldbcompare, but I just cannot connect to the mysql server with it (localhost). I created an entry into the .mylogin.cnf, using mysql_config_editor, as mentionned into the mysql utilities 1.6 documentation, and printed / tested it (with mysql), and it's ok. But if I try to run any mysql utilities command, it always fail with

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

(I put the stars myself instead of my user name).

I spent more than 2 hours searching the web, I have absolutely no clue of what's wrong... any idea ?

EDIT : alright, let's do this step by step First, my versions. Everything is on the same virtual machine : mysql server and client, and mysql utils. My versions are : MySQL server : Ver 14 Distrib 5.7.22 MySQL client : Ver 14 Distrib 5.7.22 MySQL utils : 1.6.1

  • First, using phpMyAdmin (which connects correctly to mysql), I create a user named userTest, with host % and password "bonjour!".
  • Then, I go to my host terminal, and type the following : mysql_config_editor set --login-path=test --host=localhost --user=userTest --port=3306 --password
  • When asked, I enter the password "bonjour!"
  • Then, I try to connect to mysql using the login path (no user is named "test" on the database : mysql --login-path=test
  • This connects me to mysql correctly :

    Welcome to the MySQL monitor. Commands end with ; or \g.

    Your MySQL connection id is 17

    Server version: 5.7.22-0ubuntu0.16.04.1 (Ubuntu)

    Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.


  • Now I exit mysql and type a simple mysql utils command : mysqlserverinfo --server=test

  • And I get ERROR: Access denied for user 'userTest'@'localhost' using password: YES

  • Are you login as root user?. Either user has no privileges or wrong password.

  • No, its a user I gave the needed privileges to do this. The password is correct, because if I type "mysql --login-path=exportImport", I can connect correctly. Moreover, it does not work with any of the mysql utilities command, even mysqlserverinfo. Also, I know the command can read the .mylogin.cnf, because the error I get gives the name of the user, and not the name of the login-path

OK, so my suspicions were correct. The python scripts of mysql utilies use the default "my_print_defaults" utility to get the credentials from a login path. But the my_print_defaults call returns the password as a bunch of stars, unless you call it with -s... So I modified the python script mysql/utilities/common/my_print_defaults.py to call the my_print_defaults executable with -s to get the password too. And now it works.

    If you use latest version of mysql utilities (1.6.1-2), here are the modifications to do : sudo /usr/lib/python2.7/dist-packages/mysql/utilities/common/my_print_defaults.py. In method _read_group_data(self, group), modify the calls to subprocess.call just under the comment saying # Group not found; use my_print_defaults to get group data by adding "-s" as an argument before the group : subprocess.call([self._tool_path, "-s", group], stdout=outfile...

If you can access mysql shell, run the following commands

UPDATE mysql.user SET host = '%' WHERE host = 'localhost';
Flush privileges; 

Then try logging into your utilities

  • I have access to mysql, and the server is on the same host than the mysql client I use and the mysql utils I installed. My own personal user I use to administrate is set to localhost too and I can connect correctly. I'll update the question to be more precise
