Second, modify the configuration file
Configuration file name: My-default.ini
Path: D:\mysql-5.7.13
What to set: Character encoding, MySQL directory, database directory, port number
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21st 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 |
# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html
# *** DO NOT EDIT THIS FILE. It‘s a template which will be copied to the
# *** default location during install, and will be replaced if you
# *** upgrade to a newer version of MySQL.
[client]
default-character-set=utf8
[mysqld]
# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M
# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin
# These are commonly set, remove the # and set as required.
# basedir mysql所在目录
basedir = D:\mysql-5.7.13
#datadir 数据库存放的位置 data目录没有,不能自己创建
datadir = D:\mysql-5.7.13\data
# port 服务端口,默认是3306
port = 3306
# server_id = .....
# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M

Third, initialize MySQL database table
You must open Cmd.exe as an administrator
Initialize the data directory first. If the MySQL service cannot be started without this step, the error MySQL service cannot start.

D:\mysql-5.7.13\bin>mysqld --initialize
|
Need to wait for a while, after the execution completes, will automatically generate a data directory, this directory also has the MySQL to bring the database

Iv. registering MySQL with Windows system services
You must open Cmd.exe as an administrator
1. Increase Service
1 2 |
D:\mysql-5.7.13\bin>mysqld install mysql
|
650) this.width=650; "border=" 0 "src=" http://s3.51cto.com/wyfs02/M01/83/80/wKiom1d0s4ew8oIHAAAFlqkB01I167.png "alt = "Wkiom1d0s4ew8oihaaaflqkb01i167.png"/>
Note: MySQL is the service name, you can also call other names, such as MySQL install mysql111, then the removal service and boot (close) must be mysql111
2. Remove Service Command

D:\mysql-5.7.13\bin>mysqld remove mysql
|

V. Start and close MySQL
Startup: net start MySQL
Close: net stop MySQL

Six, change the root account password 1 initial password
The initial password was generated at the time of the mysqld--initialize command,

The generated passwords are all 12-bit passwords for various characters
2. Update initialization password
After logging into MySQL, you must change the default password, otherwise report the following error

Vii. Remote Login Configuration
Allow the root user to remotely log in anywhere and have any permissions to operate on any library, as follows:
1) Log in to MySQL first using the root user:
Command line execution: Mysql-u root-p
Enter password
2) Authorize the operation:
Mysql>grant all privileges on * * to ' root ' @ '% ' identified by ' 123456 ' with GRANT OPTION;
Overload Authorization Table:
Mysql>flush privileges;
Exit Mysql:quit

Viii. commands for Telnet 1 MySQL connect to local database
User name "root", password "123456" (Note: "-P" and "123456" can not have space between)
Mysql-h Localhost-u root-p123456
2 MySQL Connection remote database (192.168.0.201)
Port "3306", username "root", password "123456"
Mysql-h 192.168.0.201-p 3306-u root-p123456
