如题，部署在阿里云机器上，config.js的配置如下

/**

• IMPORTANT (PLEASE READ THIS):
• This is not the “configuration file” of mediasoup. This is the configuration
• file of the mediasoup-demo app. mediasoup itself is a server-side library, it
• does not read any “configuration file”. Instead it exposes an API. This demo
• application just reads settings from this file (once copied to config.js) and
• calls the mediasoup API with those settings when appropriate.
