Windows 10 + MySQL 5.5 installation and usage tutorial sharing
1. To install MySQL 5.5, use
. Click the MySQL installation file directly to install, but there are relatively large ones. Probability of 2502 error and 2503 error
Solution:
##1) Find the directory :C:\Windows\temp
2) Right-click on the directory----->"Properties"----->"Security "
3) In the pop-up window, click "Advanced"
4)In the pop-up window, click "Add"
##5)In the pop-up window, click "Select Subject"
6)In the pop-up window, enter every and click "Check Name", you will find "Everyone"
##9) After clicking Apply , a security warning pops up, select "Yes"
##10) Then use MySQL Installation files, there will be no 2502 errors and 2503 errors
Note: There is a pit here, even if you set up the installation If the path is elsewhere, MySQL will still be installed in the C:\Program Files path. Of course, it will have no impact on use

2. Use the free installation of MySQL 5.5
1) Unzip the MySQL free installation file, such as Place it in D:\Java\mysql
2) Copy the my-small.ini file in the directory and name it my.ini
3) Modify the contents in my.ini
Find the [client] node, append: default-character-set = utf8
Find the [mysqld] node, append:
basedir = "D:\\Java\\MySQL"
datadir = "D: \\Java\\MySQL\\data"
##character_set_server = utf8
##collation-server = utf8_general_ci
Create a new [WinMySQLadmin] node and add: Server = D:\Java\mysql\bin\mysqld.exe
4) Append in the system variable name Path of the environment variable: D:\Java\mysql\bin;
5) In D :\Java\mysql\bin directory, execute the command (you can shift+right-click to find "Open command window here", or you can enter this directory in command line window mode): mysqld -install
This command is used to register the mysql service into the windows service. If "Service successfully installed." appears after the operation, it means that the service has been installed successfully
You can find the service through the control panel to see if there is a service named MySQL, or you can enter services.msc with win+r to directly enter the service window to see
For the corresponding uninstall service, you can execute the command: enter: mysqld -remove, prompting to uninstall the MySQL service
Similarly, the MySQL service can have a graphical interface Operate to start or close the service. You can also start the service through net start mysql in the command line window, and close the service with net stop mysql
##6) win+r input cmd to enter the command line window, enter: mysql -uroot -p and press Enter. At this time, mysql has no password by default. If "Welcome to the MySQL monitor." is displayed, it means successful login to MySQL7) Check the character set settings of the database, enter in the command line window: SHOW VARIABLES LIKE "character%"; If the displayed results are "character_set_server" and
"character_set_client" and other series of values They are all utf8, indicating that the character set is set successfully
8) Change the login password to sa, and enter in the command line window: set password for root@localhost = password( 'sa'); After logging out and logging in again, you need to enter: mysql -uroot -psa to log in successfully--------- -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- --------
3. Use of MySQL client
After repeated comparisons, I personally recommend the SQLyog client. It is simple, easy to use, powerful, and has intelligent prompts
As a coder, you may not want to go back and forth with many tools Switch, myeclipse or idea have built-in database connection tools.
Here we recommend DBeaver Core, a plug-in for eclipse. The icon looks like a cute little squirrel.
Installation method: STS is used here, of course eclipse is the same
##Fill in the connection information
Choose to load the database driver jar package
Test whether the connection is successful ## You can switch to the database operation view to perform operations ##There are some Smart prompts. It’s a pity that there are not enough smart prompts at present. For example, auto_increment doesn’t prompt, so just use it. ^_^

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.

Compared with other programming languages, MySQL is mainly used to store and manage data, while other languages such as Python, Java, and C are used for logical processing and application development. MySQL is known for its high performance, scalability and cross-platform support, suitable for data management needs, while other languages have advantages in their respective fields such as data analytics, enterprise applications, and system programming.

MySQL is worth learning because it is a powerful open source database management system suitable for data storage, management and analysis. 1) MySQL is a relational database that uses SQL to operate data and is suitable for structured data management. 2) The SQL language is the key to interacting with MySQL and supports CRUD operations. 3) The working principle of MySQL includes client/server architecture, storage engine and query optimizer. 4) Basic usage includes creating databases and tables, and advanced usage involves joining tables using JOIN. 5) Common errors include syntax errors and permission issues, and debugging skills include checking syntax and using EXPLAIN commands. 6) Performance optimization involves the use of indexes, optimization of SQL statements and regular maintenance of databases.

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
