Tutorial on installing and changing the root password of MySQL 5.7.20 decompressed version

1. Download MySQL Archive (decompressed version)

URL: https://downloads.mysql.com/archives/community/

2. Unzip the file to the custom installation directory:

There is no "data" folder and "my.ini" configuration file after decompression

3. Configure environment variables after decompression

System variables: Create a new "MYSQL_HOME" value: xxx\mysql-5.7.20-winx64 (custom installation directory root path)

Append Path:;%MYSQL_HOME%\bin

4. Create a "my.ini" configuration file in the root directory of the custom installation path

Configuration information:

[client]
port = 3306
[mysqld]
port = 3306
basedir=%MYSQL_HOME%
datadir=%MYSQL_HOME%\data
max_connections=200
character-set-server=utf8
default-storage-engine=INNODB
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
#Skip password skip-grant-tables

5. Initialize and install MySQL:

In the cmd terminal (it is recommended to run with administrator privileges)

>mysqld --initialize
>mysqld -install //Install the MySQL service. You can view the service in services.msc>net start/stop mysql //Open and close mysql

6. Set the root user password

>mysql -u root -p
enter password: Press Enter directly to enter mysql>update mysql.user set authentication_string=password('123') where user='root' and host='localhost';
mysql>flush privileges;

Exit mysql

Go to my.ini and comment out skip-grant-tables

After logging into MySQL, you will be prompted:

mysql error You must reset your password using ALTER USER statement before executing this statement.
mysql>SET PASSWORD=PASSWORD('123');
mysql>ALTER USER 'root'@'localhost' PASSWORD EXPIRE NEVER;
mysql>flush privileges;

Just log in again.
