This tutorial shows you how to configure Nginx as a reverse proxy to redirect the traffics from port 80 to Apache Tomcat on port 8080.
Here is the environment in my Linode server :
- Debian 7.5
- Nginx 1.2.1
- Tomcat 7.0.28
P.S Both Nginx and Tomcat are installed via apt-get install.
1. Tomcat Configuration
Edit server.xml, check the Tomcat listening port, and configure the default path to /apple
/etc/tomcat7/server.xml
<!-- Tomcat listen on 8080 -->
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
URIEncoding="UTF-8"
redirectPort="8443" />
<!-- Set /apple as default path -->
<Host name="localhost" appBase="webapps"
unpackWARs="true" autoDeploy="true">
<Context path="" docBase="apple">
<!-- Default set of monitored resources -->
<WatchedResource>WEB-INF/web.xml</WatchedResource>
</Context>
</Host>
Restart Tomcat, make sure when you access 127.0.0.1:8080, it will display the content in 127.0.0.1:8080/apple
2. Nginx Configuration
In Nginx, edit /etc/nginx/sites-enabled/default, put following content :
/etc/nginx/sites-enabled/default
server {
listen 80;
server_name yourdomain.com;
root /etc/tomcat7/webapps/apple;
proxy_cache one;
location / {
proxy_set_header X-Forwarded-Host $host;
proxy_set_header X-Forwarded-Server $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://127.0.0.1:8080/;
}
}
It tells Nginx to redirect the traffics from port 80 to Apache Tomcat on port 8080. Done, restart Nginx.
1 – what is “root /etc/tomcat7/webapps/apple;” for ?
2 – proxy_cache one; has error!?
Hi there, we’ve created a service (startup) called RunCloud to eliminate the tedious process of configuring NGINX and other server configs. Plus, we provide control panel to manage the server. We got 15 days free trial for you to play around. Do visit : http://runcloud.io to try it yourself today.
Looks like you will have to specific the host(ip/domain) in here as well:
So, instead of:
listen 80;
I have to change it to following:
listen 192.168.1.5:80;
This is how I conjured it.
Static files will be handled by Tomcat? I did not understand what is the reason of Nginx here.
It’s probably just to show you how it’s done. I am going to use the example myself as I’m going to have both a node-express.js server and a tomcat on my machine. I want them both to be reachable through port 80, so forwarding through nginx seems like the perfect fit.
Nginx is required because Tomcat runs on port 8080 and you cannot map a domain name to an IP address that has port 8080. You map the domain to nginx and nginx redirects the request to Tomcat.
Could you explain What you are doing in each line please. It would be helpful to us.
i got following error
Starting nginx: nginx: [emerg] “proxy_cache” zone “one” is unknown in /etc/nginx/nginx.conf:73
nginx: configuration file /etc/nginx/nginx.conf test failed
you need to put
limit_req_zone $binary_remote_addr zone=one:100m rate=1r/s;
on top of
server {
…
}
after that fix I got
[emerg] the shared memory zone “one” is already declared for a different use in /etc/nginx/sites-enabled/tct:9
even I am getting the same thing. Can someone suggest that what we can do after this ?
Even I am getting the same error
Freaking Chinese ! you’re so cool ! 😀
