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。

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
