B4J Question Install SSL on a server already running apache (Jetty)

[Douglas Farias]

Hello.

I have a VPS running cpanel/apache with several domains working correctly.

I would like to know how I can run B4J Server (Jetty) at the same time on this VPS without having problems with the ports.

I tried running a .jar generated on port 51042, without SSL and it worked fine.

But when I try to configure ssl, on port 443 I can't run the .jar because this port is already in use by apache.

I tried to change port 443 to 447 but the browser shows invalid certificate.

Could someone help me with this configuration?
I believe it is possible, as I noticed that the erel service runs on a different port and with SSL installed.

https://www.b4x.com:51041/

what I already tried.

- Generate the SSL and keystore using the VPS IP, but it gave an invalid certificate error when accessing the url.

I used sslzero to generate the SSL, but there in sslzero there is no way to add a port on the IP, only the IP.

- I also tried to use the ssl certificate of a domain that is already working in apache.

mydomain.com is already working with normal ssl.
however when I use the keystore of this ssl certificate it also shows invalid certificate error.

So I'm in doubt, should I use an ssl for my vps IP or for a domain that is already working in apache?

I would just like to access
https://ip: port

or

https://domainworkingonapache.com: port


Thxx

Hi douglas, the key to have 2 web servers on the same machine and both with SSL is called Reverse Proxy, there are plenty out there the one i like the most is Caddy.

Caddy - The Ultimate Server with Automatic HTTPS

Caddy is a powerful, enterprise-ready, open source web server with automatic HTTPS written in Go

If you are more confortable with standard technologies then you can do the same with NGINX (or however you write it)

Reverse proxy is always great solution, some on benefits in articles below:

I'm using nginx open source for all of my web sites.

For SSL you can use CertBot.

tried to change port 443 to 447 but the browser shows invalid certificate.

It has nothing to do with the port.
The problem is somewhere else.

No need to do anything special to run the server with https on other port numbers.
