Hi all,

 

I have managed to answer my own question, through trial and error - but
thought I would share the solution for those who are interested:

1.       After installing nginx, I replaced the contents of the
/etc/nginx/proxy_params file with the following:
proxy_redirect              off;
proxy_set_header        Host $host;
proxy_set_header        X-Real-IP $remote_addr;
proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header        X-Forwarded-Proto  http;

client_max_body_size    10M;

2.       Next, I added a .vhost file for my domain like so:
sudo nano /etc/nginx/sites-available/dhmis.org.vhost

3.       And inside that file I put the following:
server {
       listen 80;
       server_name www.dhmis.org dhmis.org;

        # Proxy  pass to servlet container
        location / {
                root /home/hisp/tomcat-dhis2-1/webapps/ROOT;
                proxy_pass http://localhost:8080;
                include /etc/nginx/proxy_params;
        }
        location /staging {
                root /home/hisp/tomcat-dhis2-2/webapps/staging;
                proxy_pass http://localhost:8081;
                include /etc/nginx/proxy_params;
        }
        location /training {
                root /home/hisp/tomcat-dhis2-3/webapps/training;
                proxy_pass http://localhost:8082;
                include /etc/nginx/proxy_params;
        }
}

Note that the .war files for the three instances are named "ROOT.war",
"staging.war" and "training.war" respectively, corresponding to each
location above.

4.       Next, I linked the file in etc/nginx/sites-enabled with the
sites-available folder, like so:
cd /etc/nginx/sites-enabled/
sudo ln -s /etc/nginx/sites-available/hisp.org.vhost hisp.org.vhost

5.       Next, get rid of the default file in sites-enabled:
sudo mv default /home/hisp/default

6.       And lastly, restart nginx:
sudo /etc/init.d/nginx restart

Note: no changes to nginx.conf required.

Hope that helps someone out there.  Comments, suggestions welcome.

 

Kind regards,

Jason Phillips

Subject: nginx Reverse Proxy Config for Dedicated Web Server with multiple
instances

 

Hello all,

 

I am trying to set up nginx as a reverse proxy on a dedicated web server
with three instances of Tomcat/DHIS2 (connecting to a dedicated Db Server,
successfully configured and checked).

I have been unable to make nginx behave as required, after numerous
different configurations, and hours of trawling the 'Net.

 

Attempting to following the instructions on dhis2.org resulted in bind
errors ([emerg] bind() to 0.0.0.0:80 failed (98: address already in use)),
and after several variations I tried setting up a simple reverse proxy
following the instructions on howtoforge.com at this link
<http://www.howtoforge.com/how-to-set-up-nginx-as-a-reverse-proxy-for-apache
2-on-ubuntu-12.04> .  I now have arrived at the same place, albeit by a
slightly different path, and am getting those bind errors again.  I have
even shut down all three Tomcats and removed and purged Apache (in case it
was somehow interfering, which it apparently is not).

 

The domain dhmis.org has a DNS entry for dhis, za.dhis and train.dhis
pointing to the server's IP.

My current configuration includes a file in /etc/nginx/site-available called
"dhmis.org.vhost", which is linked to the ./sites-enabled folder.  Herewith
its contents:

 

server {

        listen 80;

        server_name www.dhmis.org dhmis.org; # Have put in za.dhis.dhmis.org
and variations here.

        root /home/hisp/tomcat-dhis2-1/webapps/zanat/; # Have tried ROOT
here too!

 

        # Serve static content

        location ~
(\.js$|\.css$|\.gif$|\.woff$|\.ttf$|\.eot$|\.ico$|^/images/|^/icons/|^/dhis-
web-commons/.*\.png$) {

        add_header  Cache-Control  public;

        expires  7d;

        }

 

        # Proxy pass to servlet container

 

        location / {

                proxy_pass http://localhost:8080/; # Have added 8080/zanat
as variations here.

                include /etc/nginx/proxy_params;

        }

}

 

What am I doing wrong?

 

Kind regards,

Jason Phillips
