ubuntu - AliYunDun占用80端口会不会影响nginx的80端口？

Question

如上图，查看80端口时，被“AliYunDun”占用。

这样会不会影响nginx服务器的80端口？

我之前试验过：
把nginx服务器端口设置为80，则提示404；后来把nginx服务器端口改为81，就访问正常了。

Answer 1

I found the reason. Because my website is not registered, Alibaba Cloud will lock port 80. After registration, port 80 can be accessed normally.

Answer 2

I just took a look and the Alibaba Cloud Shield on our server uses unix sockets. You can submit a work order in the Alibaba backend to consult the after-sales technical support. They are quite responsible and can usually give you answers.
