我在centos操作系统上运行Node.js和PHP网站，我的PHP网站在端口80和443上运行良好， 我的Node.js网站在http://example.com:3000下运行良好。
为使反向代理运行http://example.com之类的node.js网站，我在使用NGINX时遇到了以下错误。

我尝试使用其他端口：NGINX的8080和8443，但它们不起作用。 当我在PHP上使用ports：8080和8443而在NGINX上使用Prots：80和443时， 然后NGINX可以正常工作，PHP站点无法正常工作。

如果有人知道如何在不打扰其他PHP网站的情况下为Node.js运行NGINX反向代理，请帮助我。
