How to Find Your MySQL Configuration File On Ubuntu

On Ubuntu, the MySQL configuration file is typically located at /etc/mysql/mysql.conf.d/mysqld.cnf. However, the actual location of the configuration file may vary depending on the version of MySQL you have installed and any customization you may have made.

Here are a few common file paths for the MySQL configuration file on Ubuntu:

  • /etc/mysql/mysql.conf.d/mysqld.cnf
  • /etc/mysql/mysql.conf.d/mysqld.cnf
  • /etc/mysql/mariadb.conf.d/50-server.cnf
  • /etc/my.cnf

To determine the exact location of the MySQL configuration file on your system, you can use the mysql --help command or inspect the MySQL service configuration. Run the following command in a terminal:

mysql --help | grep "Default options"

Look for the line that mentions "Default options" and locate the value listed for "Default options file". This will indicate the file path to the MySQL configuration file on your system.

If you are still unable to locate the configuration file, you can try searching for it using the find command, like this:

sudo find / -name "mysqld.cnf" -type f 2>/dev/null

This will search for files named mysqld.cnf on your system and display their paths. Note that this command may take some time to execute as it scans the entire file system.

Once you find the MySQL configuration file, you can proceed to edit it and make the necessary changes.
