About installing mysql 5.7 under windows
•New pitfalls to pay attention to:
After the 5.7 version is installed, the ROOT account has a default password. This password can be found under the data folder specified in the mysql.ini configuration file under Windows, in the file with the .err suffix.
2016-07-16T04:14:27.448186Z 1 [Note] A temporary password is generated for root@localhost: ?wxxx
It is best to remove characters like -, . from the mysql folder name,
There are other installation posts on the Internet that say to create a new one, my.ini. After I created it, the mysql service could not start. If you want to change the configuration, just change it directly in my-default.ini.
•For other installations, follow the installation steps in the official documentation,
Download, unzip, add the bin directory of mysql to the environment variable, and specify the bin path in path.
Run cmd, it is best to run it as admin, cd to the mysql bin directory and run the following command:
Add service command to add mysql to windows services. It can be set to start automatically: mysqld install MySQL --defaults-file="D:mysqlmysql57my-default.ini"
The command to remove the service is: mysqld remove (if you want to remove mysql, start over)
The command to start mysql on the command line cmd is: net start mysql
The command to close mysql is: net stop mysql
At this time, you can log in to mysql using mysql -u root -p, and find the password in the xx.err file.
• At this time, you can try to create a new user, create a new database, and use the newly created database for the new user,
create user xiaofang identified by 'root'; create database online_shopping; grant all privileges on online_shopping.* to xiaofang@'%' identified by 'root'; commit; flush privileges;
Then use the newly created xiaofang to connect to the database and see if it is successful.

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.
