MySQL8.nn the zip version installed (win10x64-bit systems)

First Disclaimer: This blog is mainly to record their installation process and stepped pit, wrong place please write the correct understanding.

1. Download the official website: https://dev.mysql.com/downloads/mysql/

2. Extract to the location you want to install and configure the path

 Note: all the way and then click OK.

4. Create a text file, write the following content and then save and renamed my.ini

[mysql] 
# 4.1, set the mysql client default character set is utf8 
default-Character-the SET = utf8 
[mysqld] 
# 4.2, set up port 3306 
Port = 3306 
# 4.3, set the mysql installation directory 
basedir = D: \ Promware \ MySQL \ MySQL-8.0.17-Winx64 
# 4.4, setting the server to the default character set UTF8 
character-Server-sET = UTF8 
# 4.5 of 5, to set the default storage engine InnoDB 
default = INNODB-storage-engine 
# 4.6, the maximum allowed number of connections 
max_connections = 20

  Note: 4.1, utf8 character set is not utf-8.4.3, change the path to your own extraction path .

5. initialize and mount mysql8

  5.1 Right Windows Start icon, select windows powershell (Administrator)

  5.2cd D:\Promware\MySQL\mysql-8.0.17-winx64\bin(换成你自己的路径)

  5.3执行命令进行初始化:mysqld --initialize --console

    请记住第二句输出的冒号后边的字符串:A temporary password is generated for root@localhost:这里是root用户的临时密码 

  5.4 执行命令进行安装:mysqld --install [服务名]

    中括号服务名可以不写

  5.5更改密码 

    输入命令启动mysql:net start mysql

    输入登陆命令:mysql -uroot -p这里是root用户的临时密码

    输入命令修改密码:ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '新密码';  (注意结尾的分号别丢了)

6.安装完成!!!!!

 

 

 

 

7.常见问题

  第4步中my.ini文件无法修改。原因分析:权限不够。 建议(解决方案):解压到C盘以外的目录。如果在C盘试试:右击my.ini-属性-安全

    

                     任意文件示例图

   第4步中:关于编码字符集以及存储引擎的种类和区别的请自行百度(偷个懒)。关于路径,有时路径中单斜杠会导致错误,解决方案:改为双斜杠  \\

  第5步中:mysqld命令报错,(本人在安装的时候出现过一次这个错误,首先保证前边的path配置正确且已经cd到bin目录下)有提示信息:目录下确实存在该文件,但无法运行。则根据提示信息进行将mysqld命令改为.\mysqld命令进行运行 ,运行成功。(!学计算机看懂英文真的很重要!)

  第5.4步中:中括号中的服务名可以不写,默认为mysql.如果电脑上安装多个版本的MySQL,可以根据自己的需要将服务名改为mysql8。

  最后强调一下在mysql环境中分号“;”别忘写
