How do I configure nginx as proxy to jetty?
提问by Zeynel
I've been trying to set up nginx as proxy to jetty. I want to do something as explained in this answerbut for Jetty not ring.
我一直在尝试将 nginx 设置为码头的代理。我想按照这个答案中的说明做一些事情，但 Jetty 不响。
I've created a .warand I placed it in ~/jetty/jetty-dist/webapps/web_test-0.1.0-SNAPSHOT-standalone.war
我创建了一个.war并将其放入~/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.
比如说，我想使用域 example.com，IP 地址为 198.51.100.0。
I've also copied /etc/nginx/sites-available/defaultinto the file example.comand I have it in the same directory.
我也复制/etc/nginx/sites-available/default到该文件中，example.com并将其放在同一目录中。
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.
在我的情况下，您能帮我将 nginx 配置为码头的代理吗？我知道网上有很多关于如何做到这一点的参考资料，但它们都不同，我很困惑。
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?
我需要在 nginx 中进行哪些具体更改？我需要在 jetty.xml 中进行哪些更改？我是否需要进行任何其他更改？我的应用程序会在 example.com/index.html 上提供吗？
Current state of nginx is copied below:
nginx 的当前状态复制如下：
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;
}

I was wondering if I need to use Jetty at all. In this setuphe just uses ring, which seems super easy? What do I gain by using jetty?
我想知道我是否需要使用 Jetty。在这个设置中他只使用戒指，这看起来非常简单？使用 jetty 有什么好处？

How to configure nginx to work with a java server. In the example Jetty is used.
如何配置 nginx 以与 Java 服务器一起工作。在示例中使用了 Jetty。
Edit /etc/nginx/sites-available/hostname:
编辑/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:
考虑禁用对端口 8080 的外部访问：
/sbin/iptables -A INPUT -p tcp -i eth0 --dport 8080 -j REJECT --reject-with tcp-reset
An example Jetty configuration (jetty.xml) might resemble:
示例 Jetty 配置 ( jetty.xml) 可能类似于：
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "http://www.eclipse.org/jetty/configure_9_0.dtd">

<Set name="secureScheme">https</Set>
<Set name="securePort"><Property name="jetty.tls.port" default="8443" /></Set>

<Set name="port"><Property name="jetty.port" default="8080" /></Set>
</New>
</Arg>
</Call>
</Configure>
This will cause Jetty to listen on localhost:8080and nginx to redirect requests from domain.com:80to the Jetty server.
这将导致 Jetty 侦听localhost:8080和 nginx 将请求从domain.com:80重定向到 Jetty 服务器。
