MySQL Server Instance Configuration File
----------------------------------------------------------------------
Generated by the MySQL Server Instance Configuration Wizard
Installation Instructions
----------------------------------------------------------------------
On Linux you can copy this file to /etc/my.cnf to set global options,
mysql-data-dir/my.cnf to set server-specific options
(@localstatedir@ for this installation) or to
~/.my.cnf to set user-specific options.
On Windows you should keep this file in the installation directory
of your server (e.g. C:\Program Files\MySQL\MySQL Server X.Y). To
make sure the server reads the config file use the startup option
"--defaults-file".
To run the server from the command line, execute this in a
command line shell, e.g.
mysqld --defaults-file="C:\Program Files\MySQL\MySQL Server X.Y\my.ini"
To install the server as a Windows service manually, execute this in a
command line shell, e.g.
mysqld --install MySQLXY --defaults-file="C:\Program Files\MySQL\MySQL Server X.Y\my.ini"
And then execute this in a command line shell to start the server, e.g.
net start MySQLXY
Guidelines for editing this file
----------------------------------------------------------------------
In this file, you can use all long options that the program supports.
If you want to know the options a program supports, start the program
with the "--help" option.
More detailed information about the individual options can also be
found in the manual.
For advice on how to change settings please see
http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html
CLIENT SECTION
----------------------------------------------------------------------
The following options will be read by MySQL client applications.
Note that only client applications shipped by MySQL are guaranteed
to read this section. If you want your own MySQL client program to
honor these values, you need to specify it as an option during the
MySQL client library initialization.
[client]
pipe=
socket=MYSQL
port=3306
[mysql]
no-beep
default-character-set=
SERVER SECTION
----------------------------------------------------------------------
The following options will be read by the MySQL Server. Make sure that
you have installed the server correctly (see above) so it reads this
file.
server_type=2
[mysqld]
The next three options are mutually exclusive to SERVER_PORT below.
skip-networking
enable-named-pipe
shared-memory
shared-memory-base-name=MYSQL
The Pipe the MySQL Server will use
socket=MYSQL
The TCP/IP Port the MySQL Server will listen on
port=3306
Path to installation directory. All paths are usually resolved relative to this.
basedir="C:/Program Files/MySQL/MySQL Server 5.7/"
Path to the database root
datadir=C:/ProgramData/MySQL/MySQL Server 5.7/Data
