Read the official guide and install Mysql5.6.

The last time Mysql5.6 was installed, an exception occurred after a period of time. The Mysql service could not start the process and ended: 1067. Many methods have been found on the internet, but this problem still could not be solved. I re-installed Mysql5.6 today, this problem also occurs.

MySQL 5.6 Reference Manual Including MySQL Cluster NDB 7.3 Reference Guide

This problem was finally solved.

The following is how to install Mysql On Windows.

1. Download the Mysql installation package: mysql-5.6.12-win32.zip;

2. Decompress and install the package to D :\__ dev;

3. Add environment variables and create the MYSQL_HOME variable,

   MYSQL_HOME=D:\__dev\mysql-5.6.12-win32

   Configure Path, bin

   %MYSQL_HOME%\bin;

4. Modifying mysql-5.6.12-win32 files under a my-default.ini

#Path to installation directory. All paths are usually resolved relative to this.#basedir="C:/Program Files/MySQL/MySQL Server 5.0/"basedir = D:/__dev/mysql-5.6.12-win32#Path to the database root#datadir="C:/Program Files/MySQL/MySQL Server 5.0/Data/"datadir = D:/__dev/mysql-5.6.12-win32/data

For example, configure basedir and datadir.

The Development Guide provides the following simplified configurations:

650) this. width = 650; "src =" http://www.bkjia.com/uploads/allimg/131228/221ZA627-1.png "title =" 2.png"/>

5. Run the command window with administrator privileges, switch to the Path directory, and install the Mysql service.

Service successfully installed appears in mysqld-install. This indicates that the Service is successfully installed.

6. Start the mysql Service

net start mysql

7. log on to mysql and change the root user password. The default value is null.

mysql>mysq -urootmysql>update mysql.user set password=PASSWORD('root') where User='root'

Solved, mysql5.6 configuration file in the installation directory, the name has changed to my-default.ini.

The detailed configuration information is as follows:
