shell_exec - PHPRedis做Mysql中间件的几个问题?
我开发的网站是类似 youtube 的网站,网站打算使用 redis 主从+mysql 主从方式。
大概的结构思路是这样的。
1.1
用户-->读--->redis 从--->(存在返回结果|结束|,不存在返回 0|继续下一步|)--->读 Mysql
从--->(存在返回结果并写入redis,不存在返回 0 ,结束)
1.2
用户-->写--->写 Mysql 主--->写 redis
主--->结束。(其实我希望直接写入到redis主中,然后再同步到MySQL主中,但是不知道有什么稳定成熟一点的方案,能使Redis主和Mysql主实时同步。)
大家看我这种设计方法可行不,有什么弊端和建议。
视频点击量以及顶踩等热数据直接写入 redis主 ,一天 crontab 一次到 mysql 里备份。 (定时同步,除了crontab + ( phpcli || shell.sh ) 还有什么更好的方案吗?)
在此谢谢诸位,小弟第一次过来。

你的设计方法没有问题,有一些数据库产品是可以屏蔽存储之间的差异,但是引入新的一个层,意味着额外的维护成本。
至于热数据同步到mysql备份的问题,可以在代码里面实现,例如视频点击量达到1W,2W这样的节点,就同步更新下mysql的数据。

MySQL and phpMyAdmin can be effectively managed through the following steps: 1. Create and delete database: Just click in phpMyAdmin to complete. 2. Manage tables: You can create tables, modify structures, and add indexes. 3. Data operation: Supports inserting, updating, deleting data and executing SQL queries. 4. Import and export data: Supports SQL, CSV, XML and other formats. 5. Optimization and monitoring: Use the OPTIMIZETABLE command to optimize tables and use query analyzers and monitoring tools to solve performance problems.

AI can help optimize the use of Composer. Specific methods include: 1. Dependency management optimization: AI analyzes dependencies, recommends the best version combination, and reduces conflicts. 2. Automated code generation: AI generates composer.json files that conform to best practices. 3. Improve code quality: AI detects potential problems, provides optimization suggestions, and improves code quality. These methods are implemented through machine learning and natural language processing technologies to help developers improve efficiency and code quality.

In MySQL, add fields using ALTERTABLEtable_nameADDCOLUMNnew_columnVARCHAR(255)AFTERexisting_column, delete fields using ALTERTABLEtable_nameDROPCOLUMNcolumn_to_drop. When adding fields, you need to specify a location to optimize query performance and data structure; before deleting fields, you need to confirm that the operation is irreversible; modifying table structure using online DDL, backup data, test environment, and low-load time periods is performance optimization and best practice.

To safely and thoroughly uninstall MySQL and clean all residual files, follow the following steps: 1. Stop MySQL service; 2. Uninstall MySQL packages; 3. Clean configuration files and data directories; 4. Verify that the uninstallation is thorough.

Efficient methods for batch inserting data in MySQL include: 1. Using INSERTINTO...VALUES syntax, 2. Using LOADDATAINFILE command, 3. Using transaction processing, 4. Adjust batch size, 5. Disable indexing, 6. Using INSERTIGNORE or INSERT...ONDUPLICATEKEYUPDATE, these methods can significantly improve database operation efficiency.

MySQL functions can be used for data processing and calculation. 1. Basic usage includes string processing, date calculation and mathematical operations. 2. Advanced usage involves combining multiple functions to implement complex operations. 3. Performance optimization requires avoiding the use of functions in the WHERE clause and using GROUPBY and temporary tables.

The essential Laravel extension packages for 2024 include: 1. LaravelDebugbar, used to monitor and debug code; 2. LaravelTelescope, providing detailed application monitoring; 3. LaravelHorizon, managing Redis queue tasks. These expansion packs can improve development efficiency and application performance.
