linux - 直接输入一个域名，如何访问指定的端口

Question

现在是这种情况
1.vps上的博客已经搭建好了，用的是express，后台服务常驻，监听3000端口
2.购买了域名，设置好了解析。
3.通过www.example.com:3000和107.107.107.107：3000(举个例子吧)都能访问主页。

那么怎样做才能 输入www.example.com后就能直接访问主页内容呢？

Answer 1

Listen directly to port 80, or use other software (nginx, apache, etc.) to act as a proxy on port 80

Answer 2

Thank you for the invitation.
This question should be available on Baidu, keyword:

• apache port forwarding

• nginx port forwarding

In addition, if you are not using port 80, you can directly set up listening port 80.

Answer 3

means that my blog also uses express and listens to port 3000. It can be used directly after domain name resolution. . .

Answer 4

Thank you for the invitation.
Install Nginx, and then use proxy_pass to reverse proxy to localhost:3000.

Answer 5

nginx reverse proxy

Answer 6

Use nginx to listen to port 3000 and forward the request to your server

Answer 7

The answer has been mentioned above. I think iptable port forwarding should work without nginx. You can try it!

Answer 8

The default HTTP port is 80. When the domain name does not specify a port, port 80 is used
So you can just listen to 80

——Or do you mean that your server cannot use port 80, or it is occupied by other processes?

Answer 9

Just listen to port 80, which is the default port number of HTTP

Answer 10

Http accesses port 80 by default, there are two solutions

• One is to directly access the port number. For example, for port 8080, use hello.com:8080 to access

• Another method that a friend mentioned before is to set up a reverse proxy, such as the famous nginx and apache.

From your question, I think you can take a look at the reverse proxy mode of nginx, search it on Baidu or Google:

Nginx reverse proxy
