Can't run Javalin backend and Apache web host at the same time

I've made a Javalin backend host that I've been starting on 0.0.0.0:7000 for a while now, but I recently began using Apache2 for the frontend content-serving. I was able to get apache set up, and it's running great, but now my backend won't start, with the error Failed to bind to 0.0.0.0/0.0.0.0:80 and then later Failed to bind to 0.0.0.0/0.0.0.0:443. How can I configure this so that both run at the same time, and I can use my backend server to handle requests to mysite.com/api/, but requests to mysite.com/ are served by apache?

Solution

  • You're using the SSL Plugin, if so you must configure your ports in the plugin config.

    For example:

    SSLPlugin plugin = new SSLPlugin(conf -> {
    conf.pemFromPath("/path/to/cert.pem", "/path/to/key.pem");
    conf.insecurePort = 80;                     
    conf.securePort = 443; 

    // additional configuration options
});

    However, since you're using Apache as a reverse proxy you might not need the SSL plugin at all, since Apache can terminate your SSL connections for you. Unencrypted traffic will only be exchanged between Apache and Javalin: app diagram
