Of course you have to download it firsthttps://dev.mysql.com/downloads/mysql/ Official website download address. (Related mysql video tutorial recommendation: "mysql tutorial")

Choose the version that suits your computer, click Download, jump, and download directly No thanks.

Wait quietly for downloading and decompression. This is my decompression path D:\MySQL

Officially start the installation

#：MySQL5.7.19

#After decompression

#However, there is no my.ini

#设置3306端口
port = 3306[mysqld]
#设置3306端口

##This computer->Right-click, Properties->Advanced System Settings->Environment Variables

Variable name: MYSQL_HOME

##Variable value: Your own MySQL installation path

Next add Path, select Path editing, and add a new one: %MYSQL_HOME%\bin

##Confirm all the way.

#Open the command prompt, you must have administrator rights, otherwise the rights will not be enough.

cd /dD:\MySQL\bin Enter the bin directory. To enter the bin directory! It’s not written on the picture!

Then press the command in the picture.

Next mysql -u root -p enter MySQL It is not necessary to enter for the first time For password, just press Enter. Because I installed it before, I need a password.

Next update the password

SO:

mysql>update mysql.user set anthentication_string=password('你的密码') where user='root';
mysql>flush privileges;//刷新MySQL的系统权限
mysql>quit;

再次mysql -u root -p进入就可以操作了。

mysql>show databases;

也可以下一个MySQL的图形化界面，SQLyog、Navicat之类的。

忘记root密码

也许时间久了密码会忘。

看图。

首先net stop mysql停掉服务；

若是停不掉：

Ctrl+Alt+Del打开任务管理器，在详细信息里结束mysql.exe任务。

进入bin目录

mysqld -nt --skip-grant-tables

现在这个命令提示符已经不可以继续用了。

重新打开一个管理员命令提示符输入mysql进入重新改密码就OK了。
