In database applications, MySQL is one of the most popular open source databases. It has the characteristics of high speed, ease of use and stability. Although the installation of MySQL is not very difficult, some novices may encounter some problems with some details. The following introduces a green version of MySQL installation method.
- Download MySQL
First, we need to download the green version of MySQL. You can find various versions and platforms of MySQL on the MySQL official website download page, and you can choose to download according to your needs and operating system version. For this tutorial, we choose MySQL 5.7 version and download the green version zip package.
- Extract the file and rename the folder
After downloading MySQL, unzip the file and name the decompressed folder MySQL or another name you like, such as mysql -5.7.
- Configure environment variables
After completing the folder renaming, you need to add the MySQL address path to the environment variable to facilitate subsequent operations. Taking the Windows system as an example, right-click "My Computer" - "Properties" - "Advanced System Settings" - "Environment Variables", find the "System Variables" column, find the "Path" variable in it, and click the Edit button Add the decompressed MySQL address path and save it.
- Configuring the MySQL password and port
Before starting to install MySQL, you need to configure the MySQL default port and password to ensure more secure and stable use. MySQL.
Find the my.ini file in the MySQL folder, edit the [mysqld] part, and set the MySQL service port number, for example, change port=3306 to port=5000. In the [mysql] section, find the password item and change it to your password, such as password=123456.
Then find the bin directory of the folder where MySQL is located, hold down the Shift key and right-click a blank space, select "Open command window here" (or select "Open Power Shell window here"), enter mysqld -install and press Enter to install the MySQL service. If you have not configured environment variables, you need to access them through the full path. For example: C:\mysql\bin\mysqld --install.
- Connecting to MySQL
There are many MySQL connection tools, such as MySQL Workbench, navicat for MySQL, heidisql, mysql shell (command line connection method). Here, take MySQL Workbench as an example. Open MySQL Workbench and click the "New Connection" button. A window will open. Select the connection type as "MySQL", enter the host name as "localhost", the input port as "5000", and the user name as " root" (administrator account), the password is "123456" (the password configured by yourself), as shown below:
- Installation completed
After completing the above steps, that is You can complete the installation of the basic MySQL green version, and happily use MySQL to write your database applications!

Explain the ACID properties (Atomicity, Consistency, Isolation, Durability).Apr 16, 2025 am 12:20 AMACID attributes include atomicity, consistency, isolation and durability, and are the cornerstone of database design. 1. Atomicity ensures that the transaction is either completely successful or completely failed. 2. Consistency ensures that the database remains consistent before and after a transaction. 3. Isolation ensures that transactions do not interfere with each other. 4. Persistence ensures that data is permanently saved after transaction submission.
MySQL: Database Management System vs. Programming LanguageApr 16, 2025 am 12:19 AMMySQL is not only a database management system (DBMS) but also closely related to programming languages. 1) As a DBMS, MySQL is used to store, organize and retrieve data, and optimizing indexes can improve query performance. 2) Combining SQL with programming languages, embedded in Python, using ORM tools such as SQLAlchemy can simplify operations. 3) Performance optimization includes indexing, querying, caching, library and table division and transaction management.
MySQL: Managing Data with SQL CommandsApr 16, 2025 am 12:19 AMMySQL uses SQL commands to manage data. 1. Basic commands include SELECT, INSERT, UPDATE and DELETE. 2. Advanced usage involves JOIN, subquery and aggregate functions. 3. Common errors include syntax, logic and performance issues. 4. Optimization tips include using indexes, avoiding SELECT* and using LIMIT.
MySQL's Purpose: Storing and Managing Data EffectivelyApr 16, 2025 am 12:16 AMMySQL is an efficient relational database management system suitable for storing and managing data. Its advantages include high-performance queries, flexible transaction processing and rich data types. In practical applications, MySQL is often used in e-commerce platforms, social networks and content management systems, but attention should be paid to performance optimization, data security and scalability.
SQL and MySQL: Understanding the RelationshipApr 16, 2025 am 12:14 AMThe relationship between SQL and MySQL is the relationship between standard languages and specific implementations. 1.SQL is a standard language used to manage and operate relational databases, allowing data addition, deletion, modification and query. 2.MySQL is a specific database management system that uses SQL as its operating language and provides efficient data storage and management.
Explain the role of InnoDB redo logs and undo logs.Apr 15, 2025 am 12:16 AMInnoDB uses redologs and undologs to ensure data consistency and reliability. 1.redologs record data page modification to ensure crash recovery and transaction persistence. 2.undologs records the original data value and supports transaction rollback and MVCC.
What are the key metrics to look for in an EXPLAIN output (type, key, rows, Extra)?Apr 15, 2025 am 12:15 AMKey metrics for EXPLAIN commands include type, key, rows, and Extra. 1) The type reflects the access type of the query. The higher the value, the higher the efficiency, such as const is better than ALL. 2) The key displays the index used, and NULL indicates no index. 3) rows estimates the number of scanned rows, affecting query performance. 4) Extra provides additional information, such as Usingfilesort prompts that it needs to be optimized.
What is the Using temporary status in EXPLAIN and how to avoid it?Apr 15, 2025 am 12:14 AMUsingtemporary indicates that the need to create temporary tables in MySQL queries, which are commonly found in ORDERBY using DISTINCT, GROUPBY, or non-indexed columns. You can avoid the occurrence of indexes and rewrite queries and improve query performance. Specifically, when Usingtemporary appears in EXPLAIN output, it means that MySQL needs to create temporary tables to handle queries. This usually occurs when: 1) deduplication or grouping when using DISTINCT or GROUPBY; 2) sort when ORDERBY contains non-index columns; 3) use complex subquery or join operations. Optimization methods include: 1) ORDERBY and GROUPB
