nginx配置静态和nodejs应用程序

Question

我们有多个nodejs应用程序在不同的端口运行并使用nginx作为代理。由于nginx.conf

中的某些错误的正则表达式，我们在访问静态文件网址时遇到（504）问题

任何人都遇到过类似的网址模式。任何指针都会有所帮助

nginx version 1.8.0

504网关问题

https://localhost:9443/js/app1/index.js
https://localhost:9443/css/app1/index.css

https://localhost:9443/js/app2/index.js
https://localhost:9443/css/app2/index.css

Answer 1

显然https://localhost:9443/js/app1/index.js匹配app1的正则表达式，因为它包含文本/app1/。

正则表达式位置优先于普通前缀位置，因此在上述情况下不使用location /js块。

阅读the documentation以了解location指令的评估顺序。

您可以使用js修饰符，将css和^~位置的优先顺序移动到所有正则表达式位置之上：

location ^~ /js { ... }
location ^~ /css { ... }

这些仍然作为前缀位置，但具有更高的优先级。

这是我尝试过的，它有效。得到了这篇文章的帮助 nginx - serve only images
