As of MySQL 5.7.18, my-default.ini is no longer included in or installed by distribution packages.
文档里的安装流程：
https://dev.mysql.com/doc/refman/5.7/en/windows-install-archive.html
- Extract the main archive to the desired install directory
- Optional: also extract the debug-test archive if you plan to execute the MySQL benchmark and test suite
- Create an option file
- Choose a MySQL server type
- Initialize MySQL
- Start the MySQL server
- Secure the default user accounts

; Example MySQL config file for medium systems.
;
; This is for a large system with memory of 1G-2G where the system runs mainly
; MySQL.
;
; MySQL programs look for option files in a set of
; locations which depend on the deployment platform.
; You can copy this option file to one of those
; locations. For information about these locations, see:
; http://dev.mysql.com/doc/mysql/en/option-files.html
;
; In this file, you can use all long options that a program supports.
; If you want to know which options a program supports, run the program
; with the "--help" option.
; The following options will be passed to all MySQL clients

; Replication Slave (comment out master section to use this)
; New for MySQL 5.6 if no slave
skip-slave-start
;
; To configure this host as a replication slave, you can choose between
; two methods :
;
; 1) Use the CHANGE MASTER TO command (fully described in our manual) -
; the syntax is:
;
; CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
; MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
;
; where you replace <host>, <user>, <password> by quoted strings and
; <port> by the master's port number (3306 by default).
;
; Example:
;
; CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
; MASTER_USER='joe', MASTER_PASSWORD='secret';
;
; OR
;
; 2) Set the variables below. However, in case you choose this method, then
; start replication for the first time (even unsuccessfully, for example
; if you mistyped the password in master-password and the slave fails to
; connect), the slave will create a master.info file, and any later
; change in this file to the variables' values below will be ignored and
; overridden by the content of the master.info file, unless you shutdown
; the slave server, delete master.info and restart the slaver server.
; For that reason, you may want to leave the lines below untouched
; (commented) and instead use CHANGE MASTER TO (see above)
;
; required unique id between 2 and 2^32 - 1
; (and different from the master)
; defaults to 2 if master-host is set
; but will not function as a slave if omitted
;server-id = 2
;
; The replication master for this slave - required
;master-host = <hostname>
;
; The username the slave will use for authentication when connecting
; to the master - required
;master-user = <username>
;
; The password the slave will authenticate with when connecting to
; the master - required
;master-password = <password>
;
; The port the master is listening on.
; optional - defaults to 3306
;master-port = <port>
;
; binary logging - not required for slaves, but recommended
