- your MySQL must not be locked on localhost (edit the my.cnf file)
- you must have a mysql user authorized from another IP/host than localhost
ah okey thanks, how can i find the my.cnf file? which directory
so... i open my.cnf and he push me to mysql.cnf. is this okey ?

I found that on google. do I have to change something?
#
# The MySQL database server configuration file.
#
# You can copy this to one of:
# - "/etc/mysql/my.cnf" to set global options,
# - "~/.my.cnf" to set user-specific options.
#
# One can use all long options that the program supports.
# Run program with --help to get a list of available options and with
# --print-defaults to see which it would actually understand and use.
#
# For explanations see
# http://dev.mysql.com/doc/mysql/en/server-system-variables.html
#
# * IMPORTANT: Additional settings that can override those from this file!
# The files must end with '.cnf', otherwise they'll be ignored.

# Optimized my.cnf configuration for MySQL/MariaSQL
#
# by Fotis Evangelou, developer of Engintron (engintron.com)
#
# ~ Updated January 2020 ~
#
#
# The settings provided below are a starting point for a 2GB - 4GB RAM server with 2-4 CPU cores.
# If you have different resources available you should adjust accordingly to save CPU, RAM & disk I/O usage.
#
# The settings marked with a specific comment or the word "UPD" (after the value)
# should be adjusted for your system by using database diagnostics tools like:
#
# https://github.com/major/MySQLTuner-perl
# or
# https://github.com/RootService/tuning-primer (supports MySQL up to v5.7)
#
# Run either of these scripts before optimizing your database, at least 1 hr after the optimization & finally
# at least once a day for 3 days (without restarting the database) to see how your server performs and if you need
# to re-adjust anything. The more MySQL/MariaDB runs without restarting, the more usage data it gathers, so these
# diagnostics scripts will report in mode detail how MySQL/MariaDB performs.
#
#
# IMPORTANT NOTE: If there is NO comment after a setting value, then 99,9% of the times you won't need to adjust it.
#
#
# --- THINGS TO DO AFTER YOU UPDATE MY.CNF - TROUBLESHOOTING ---
#
# If any terminal commands are mentioned, make sure you execute them as "root" user.
#
# If MySQL or MariaDB cannot start (or restart), then perform the following actions.
#
# 1. If the server had the stock database configuration and you added or updated any
# "innodb_log_*" settings (as suggested below), then execute these commands ONLY
# the first time you apply this configuration:
#
# $ rm -rvf /var/lib/mysql/ib_logfile*
# $ chown -R mysql:mysql /var/lib/mysql
# $ service mysql restart
#
# or use the shorthand command:
# $ rm -rvf /var/lib/mysql/ib_logfile*; chown -R mysql:mysql /var/lib/mysql; service mysql restart
#
# 2. If the setting "bind-address" is not commented out, then make sure the file /etc/hosts is
# properly configured. A good example of a "clean" /etc/hosts file is something like this:
#
# 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
# ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
# 1.2.3.4 hostname.domain.tld hostname # <-- Replace accordingly!
#
# Finally restart the database service:
#
# $ service mysql restart
#
# 3. If the database service cannot restart even after the first 2 steps, make sure the database data folder
# (common for either MySQL or MariaDB) "/var/lib/mysql" is owned by the "mysql" user AND group.
# Additionally, the folder itself can have 0751 or 0755 file permissions. To fix it, simply do this:
# $ chown -R mysql:mysql /var/lib/mysql
# $ chmod 0755 /var/lib/mysql
#
# Finally restart the database service:
#
# $ service mysql restart
#
#
