1. Install the MySQL server

• Download and install MySQL from the MySQL official website Community Edition or Enterprise Edition.
• Follow the installation wizard and make sure you select the correct installation options.

2. Create a database

• Use a MySQL command line client (for example, MySQL Workbench) to connect to the MySQL server.

• Enter the following command to create the database:

  <code>CREATE DATABASE <数据库名称>;</code>

3. Create a user and grant permissions

• Enter the following command to create a user and grant access to the database:

  <code>CREATE USER '<用户名>'@'<主机名>' IDENTIFIED BY '<密码>';
  GRANT ALL PRIVILEGES ON <数据库名称>.* TO '<用户名>'@'<主机名>';</code>

4. Connect to the database

• Use the following command to connect to the newly created database:

  <code>USE <数据库名称>;</code>

5. Create the table

• Enter the following command Create table:

  <code>CREATE TABLE <表名称> (<列定义>);</code>

6. Insert data

• Use the following command to insert data:

  <code>INSERT INTO <表名称> (<列名>) VALUES (<值>);</code>

7. Query data

• Use the following command to query data:

  <code>SELECT <列名> FROM <表名称> WHERE <条件>;</code>

8. Modify data

• Use the following command to modify data:

  <code>UPDATE <表名称> SET <列名> = <新值> WHERE <条件>;</code>

9. Delete data

• Use the following command to delete data:

  <code>DELETE FROM <表名称> WHERE <条件>;</code>

10. Back up the database

• Back up the database regularly to prevent data loss:
