@AntonVeselov -The tasksel command line utility allows using the menu system to select one or more groups of packages and install them on your Ubuntu system.

    ErrorAccess denied for user 'root' @ 'localhost'means that the root user with the password you specify does not have access to the DBMS.

    Apparently the password was not set or was set incorrectly, or instead of 'root' @ 'localhost' the user 'root'@ was installed. Try typing in the console

    mysql -h -u root -p

    If after that you are allowed into the DBMS, you need to create an additional user 'root' @ 'localhost'

    GRANT ALL ON *. * TO 'root' @ 'localhost'
    IDENTIFIED BY 'password'

    If it doesn't, then you need to restore the root password. Find the configuration file my.cnf and add the directive to the [mysqld] sectionskip-grant-tableswhich will disable access rights checking


    Then restart the server. Now you can login MySQL without password, login and reset password

    SET PASSWORD FOR 'root' @ 'localhost'= PASSWORD ('new_password');

    After that, remove the directiveskip-grant-tablesfrom my.cnf and restart the server.

    It is also worth recalling that the skip grant table must be commented out after setting a new password.

    SET PASSWORD FOR 'root' @ 'localhost'= PASSWORD ('root') MySQL response: Documentation # 1290 -The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement

    Where can I find my.cnf config file in Ubuntu?

    You can focus on table 4.2 at dev.mysql.com/doc/refman/8.0/en/option-files.html MySQL will sequentially poll folders in the order in which they are listed in the table. The file that is found first will be used.

    You just need to enter:

    sudo mysql_secure_installation

    and answer questions then we log in:

    sudo mysql -h localhost -u root -p
  • Answer # 3

    in newer versions after MySQL 5.7.6, the password change command is slightly different:

    ALTER USER 'root' @ 'localhost' IDENTIFIED BY 'new_password';
