Configure MySQL database with Python: automated user authorization tool

First, make sure you have installed the mysql-connector-python library, if not installed, you can use the following command to install

pip install mysql-connector-python

Then, here is the content of the python script

import mysql.connector
from mysql.connector import Error

def create_user(host_name, user_name, user_password, new_user_name, new_user_password, db_name):
    # 创建数据库连接
    connection = mysql.connector.connect(host=host_name, 
                                         user=user_name, 
                                         passwd=user_password)
    cursor = connection.cursor()
    try:
        # 创建新用户
        cursor.execute(f"CREATE USER '{
      
      new_user_name}'@'localhost' IDENTIFIED BY '{
      
      new_user_password}';")
        
        # 授予新用户对指定数据库的所有权限
        cursor.execute(f"GRANT ALL PRIVILEGES ON {
      
      db_name} . * TO '{
      
      new_user_name}'@'localhost';")
        
        # 提交修改
        connection.commit()
        
        print(f"User {
      
      new_user_name} created successfully.")
    except Error as e:
        print(f"Error: '{
      
      e}'")
    finally:
        # 关闭数据库连接
        cursor.close()
        connection.close()

# 使用你的MySQL服务器详细信息替换下面的值
host_name = "localhost"
user_name = "root"
user_password = "rootpassword"

# 创建的新用户的用户名和密码
new_user_name = "newuser"
new_user_password = "newpassword"

# 要授予权限的数据库
db_name = "mydatabase"

create_user(host_name, user_name, user_password, new_user_name, new_user_password, db_name)

When you run this script, it will connect to the MySQL server, create a new user, and grant that user all privileges on the specified database.

Note: Please make sure you have sufficient permissions to create users and grant permissions, and be very careful when using this script, as it involves database security.
