How do I configure nginx as proxy to jetty?

I've been trying to set up nginx as proxy to jetty. I want to do something as explained in this answer but for Jetty not ring.

I've created a

and I placed it in

Say, I want to use the domain example.com with ip address

I've also copied
into the file
and I have it in the same directory.

Can you help me configure nginx as proxy to jetty in my case? I know there are many references online about how to do this but they are all different and I got confused.

What specific changes do I need to make in nginx? What changes do I need to make in jetty.xml? Do I need to make any other changes? Will my app be served at example.com/index.html?

Current state of nginx is copied below:

upstream jetty {
server fail_timeout=0

server {
listen 80 default_server;
#listen [::]:80 default_server ipv6only=on;

root /usr/share/nginx/html;
index index.html index.htm;

server_name localhost;

location / {
proxy_pass http://jetty

try_files $uri $uri/ =404;


I was wondering if I need to use Jetty at all. In this setup he just uses ring, which seems super easy? What do I gain by using jetty?

How to configure nginx to work with a java server. In the example Jetty is used.

Edit /etc/nginx/sites-available/hostname:

server {
  listen       80;
  server_name  hostname.com;

  location / {
    proxy_pass       http://localhost:8080;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;

Consider disabling external access to port 8080:

/sbin/iptables -A INPUT -p tcp -i eth0 --dport 8080 -j REJECT --reject-with tcp-reset

An example Jetty configuration (jetty.xml) might resemble:

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "http://www.eclipse.org/jetty/configure_9_0.dtd">

 | http://eclipse.org/jetty/documentation/current/configuring-connectors.html
<Configure id="Server" class="org.eclipse.jetty.server.Server">
  <New id="httpConfig" class="org.eclipse.jetty.server.HttpConfiguration">
    <Set name="secureScheme">https</Set>
    <Set name="securePort"><Property name="jetty.tls.port" default="8443" /></Set>
    <Set name="outputBufferSize">65536</Set>
    <Set name="requestHeaderSize">8192</Set>
    <Set name="responseHeaderSize">8192</Set>
  <Call name="addConnector">
      <New class="org.eclipse.jetty.server.ServerConnector">
        <Arg name="server"><Ref refid="Server" /></Arg>
        <Arg name="acceptors" type="int"><Property name="http.acceptors" default="-1"/></Arg>
        <Arg name="selectors" type="int"><Property name="http.selectors" default="-1"/></Arg>
        <Arg name="factories">
          <Array type="org.eclipse.jetty.server.ConnectionFactory">
              <New class="org.eclipse.jetty.server.HttpConnectionFactory">
                <Arg name="config"><Ref refid="httpConfig" /></Arg>
        <Set name="host"><Property name="jetty.host" default="localhost" /></Set>
        <Set name="port"><Property name="jetty.port" default="8080" /></Set>

This will cause Jetty to listen on localhost:8080 and nginx to redirect requests from domain.com:80 to the Jetty server.
