vagran环境配置好了,写代码在host,测试在guest的工作流确实很方便,但是马上就问题来了,每次要查看mysql中内容时候,还需要登陆到guest中通过命令行查看,有的同学举手说,可以安装phpmyadmin通过浏览器查看,确实是个好方法, 但是对我这种非phper,总感觉为了看个mysql,还要装个php环境好累赘。其实优雅的解决方法还是有的,那就是通过mysql GUI client直接对guest中的mysql进行连接查看,GUI客户端,我用的是Sequl pro(Mac环境下最好得mysql可视化客户端)。 guest主机用的是Ubuntu 14.04 具体操作如下:
首先得保证mysql可以被localhost
之外的主机访问到,这里需要配置my.conf
文件中的bind-address = 0.0.0.0
,然后重启mysql服务sudo service mysql restart
,之后配置当前mysql账号的权限问题了,两种方法:
- 修改myql的user表,把host一项从
localhost
修改为%
mysql -uroot -p #进入mysql mysql> use mysql #进入mysql数据库 mysql> update usre set host = '%' where user = 'root' #修改 mysql> select host user from user; #查看修改结果
- 通过执行授权命令,原理与上面一样,即添加允许访问的host机地址
GRANT ALL PRIVILEGES ON *.* TO root@my_ip IDENTIFIED BY ‘root_password‘ WITH GRANT OPTION;
注意上面的my_ip
处,你可以填写host机的地址,也可以填写一个通配的'%'
上面两步操作完之后就可以正常通过host机直接访问guest中的mysql数据了
-完-

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
