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 .war
and I placed it in ~/jetty/jetty-dist/webapps/web_test-0.1.0-SNAPSHOT-standalone.war
Say, I want to use the domain example.com with ip address 198.51.100.0.
I've also copied /etc/nginx/sites-available/default
into the file example.com
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 127.0.0.1:8080 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;
}
EDIT
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">
<!--

</Array>

<Set name="host"><Property name="jetty.host" default="localhost" /></Set>
<Set name="port"><Property name="jetty.port" default="8080" /></Set>
</New>
</Arg>
</Call>
</Configure>
This will cause Jetty to listen on localhost:8080 and nginx to redirect requests from domain.com:80 to the Jetty server.
