Mysql database is a popular relational database management system that provides a complete SQL support and can be integrated with many programming languages and tools. When developing and managing databases, it is often necessary to change the password of the root user. This article will introduce you to some simple steps to change the Mysql database root password on Linux and Windows systems.
1. Change the Mysql database root password on Linux system
Step 1: Connect to your server via SSH. You can use your favorite terminal tools. Enter the following command in the terminal to connect to your server:
ssh username@server_ip_address
Note: The "username" above should be the username of your server, and "server_ip_address" should be the IP address of your server.
Step 2: Connect to Mysql database. Enter the following command in the terminal to connect to the Mysql database:
mysql -u root -p
Note: After entering the command, you will be asked to enter the Mysql root user password. If you haven't set a password yet, skip this step and just press Enter.
Step 3: Use the following command to change the root password of the Mysql database:
ALTER USER 'root'@'localhost' IDENTIFIED BY 'new_password';
Note: Please replace "new_password" with the new password you need to change.
After the above steps are completed, you should receive an output indicating that you have successfully changed your password.
2. Change the Mysql database root password on Windows system
Step 1: Open the Mysql command line interface. Click on the Windows button and start typing "CMD" to open a command prompt window on Windows operating system. In the window, enter the following command to open the command line interface of Mysql:
mysql -u root -p
Note: After entering the command, you will be asked to enter the Mysql root user password. If you haven't set a password yet, skip this step and just press Enter.
Step 2: Use the following command to change the root password of the Mysql database:
ALTER USER 'root'@'localhost' IDENTIFIED BY 'new_password';
Note: Please replace "new_password" with the new password you need to change.
After the above steps are completed, you should receive an output indicating that you have successfully changed your password.
Summary
Changing the Mysql database root password on Linux and Windows systems is very simple. If you have forgotten the current user's password, or want to add more users to access your database, please visit Mysql's official documentation website for more information and explore more knowledge about Mysql database. I wish you success!

MySQL is suitable for beginners to learn database skills. 1. Install MySQL server and client tools. 2. Understand basic SQL queries, such as SELECT. 3. Master data operations: create tables, insert, update, and delete data. 4. Learn advanced skills: subquery and window functions. 5. Debugging and optimization: Check syntax, use indexes, avoid SELECT*, and use LIMIT.

MySQL efficiently manages structured data through table structure and SQL query, and implements inter-table relationships through foreign keys. 1. Define the data format and type when creating a table. 2. Use foreign keys to establish relationships between tables. 3. Improve performance through indexing and query optimization. 4. Regularly backup and monitor databases to ensure data security and performance optimization.

MySQL is an open source relational database management system that is widely used in Web development. Its key features include: 1. Supports multiple storage engines, such as InnoDB and MyISAM, suitable for different scenarios; 2. Provides master-slave replication functions to facilitate load balancing and data backup; 3. Improve query efficiency through query optimization and index use.

SQL is used to interact with MySQL database to realize data addition, deletion, modification, inspection and database design. 1) SQL performs data operations through SELECT, INSERT, UPDATE, DELETE statements; 2) Use CREATE, ALTER, DROP statements for database design and management; 3) Complex queries and data analysis are implemented through SQL to improve business decision-making efficiency.

The basic operations of MySQL include creating databases, tables, and using SQL to perform CRUD operations on data. 1. Create a database: CREATEDATABASEmy_first_db; 2. Create a table: CREATETABLEbooks(idINTAUTO_INCREMENTPRIMARYKEY, titleVARCHAR(100)NOTNULL, authorVARCHAR(100)NOTNULL, published_yearINT); 3. Insert data: INSERTINTObooks(title, author, published_year)VA

The main role of MySQL in web applications is to store and manage data. 1.MySQL efficiently processes user information, product catalogs, transaction records and other data. 2. Through SQL query, developers can extract information from the database to generate dynamic content. 3.MySQL works based on the client-server model to ensure acceptable query speed.

The steps to build a MySQL database include: 1. Create a database and table, 2. Insert data, and 3. Conduct queries. First, use the CREATEDATABASE and CREATETABLE statements to create the database and table, then use the INSERTINTO statement to insert the data, and finally use the SELECT statement to query the data.

MySQL is suitable for beginners because it is easy to use and powerful. 1.MySQL is a relational database, and uses SQL for CRUD operations. 2. It is simple to install and requires the root user password to be configured. 3. Use INSERT, UPDATE, DELETE, and SELECT to perform data operations. 4. ORDERBY, WHERE and JOIN can be used for complex queries. 5. Debugging requires checking the syntax and use EXPLAIN to analyze the query. 6. Optimization suggestions include using indexes, choosing the right data type and good programming habits.
