Where does mysql store data?

I just installed MySQL Server 5.7 on Windows 10 and my.ini file is located here c:\ProgramData\MySQL\MySQL Server 5.7\my.ini.

The Data folder (where your dbs are created) is here C:/ProgramData/MySQL/MySQL Server 5.7\Data.

From here:

Windows

1. Locate the my.ini, which store in the MySQL installation folder.

For Example, C:\Program Files\MySQL\MySQL Server 5.1\my.ini

2. Open the “my.ini” with our favor text editor.

#Path to installation directory. All paths are usually resolved relative to this.
basedir="C:/Program Files/MySQL/MySQL Server 5.1/"
 
#Path to the database root
datadir="C:/Documents and Settings/All Users/Application Data/MySQL/MySQL Server 5.1/Data/"

Find the “datadir”, this is the where does MySQL stored the data in Windows.

Linux

1. Locate the my.cnf with the find / -name my.cnf command.

yongmo@myserver:~$ find / -name my.cnf
find: /home/lost+found: Permission denied
find: /lost+found: Permission denied
/etc/mysql/my.cnf

2. View the my.cnf file like this: cat /etc/mysql/my.cnf

yongmo@myserver:~$ cat /etc/mysql/my.cnf
#
# 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.
# 
[mysqld]
#
# * Basic Settings

user   = mysql
pid-file = /var/run/mysqld/mysqld.pid
socket  = /var/run/mysqld/mysqld.sock
port   = 3306
basedir  = /usr
datadir  = /var/lib/mysql
tmpdir  = /tmp
language = /usr/share/mysql/english

3. Find the “datadir”, this is where does MySQL stored the data in Linux system.

In version 5.6 at least, the Management tab in MySQL Workbench shows that it's in a hidden folder called ProgramData in the C:\ drive. My default data directory is

C:\ProgramData\MySQL\MySQL Server 5.6\data

. Each database has a folder and each table has a file here.

Reading between the lines - Is this an innodb database? In which case the actual data is normally stored in that directory under the name ibdata1. This file contains all your tables unless you specifically set up mysql to use one-file-per-table (innodb-file-per-table)
