Nginx reverse proxy setting - nginx

I am totally new to Nginx and need your help.
Basically I have a single server with single IP address, but I want to host two different web application within the server with different domain name. So, basically, for each domain name, I want it to redirect to different port number. I tried below and got an error
[root#mysvr nginx]# nginx -t -c /etc/nginx/nginx.conf
nginx: [emerg] "proxy_pass" directive is not allowed here in /etc/nginx/nginx.conf:41
nginx: configuration file /etc/nginx/nginx.conf test failed
Following is the Nginx setting. Line 41 is where the proxy_pass is.
server {
listen 80;
server_name server1.com www.server1.com;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://127.0.0.1:1003;
}
server {
listen 80;
server_name server2.com www.server2.com;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://192.168.1.1:1004;
}
Thank you!

If you check the docs for proxy_pass, proxy_pass needs to be in a location, if in location or limit_except block. You have it in a server block.
Try replacing your usage of proxy_pass with
location / {
proxy_pass ...
}

nginx reverse proxy for application

I use nginx for reverse proxy with domain name. I've some application publish on IIS and i want to proxy different location name for each application.
For example;
Domain name on nginx :
example.com.tr
application end points for app:
1.1.1.1:10
1.1.1.2:10
upstream for app in nginx.conf:
upstream app_1 {
least_conn;
server 1.1.1.1:10;
server 1.1.1.2:10;
}
server {
listen 443 ssl;
server_name example.com.tr;
proxy_set_header X-Forwarded-Port 443;
ssl_certificate /etc/cert.crt;
ssl_certificate_key /etc/cert.key;
location /app_1/ {
proxy_pass http://app_1/;
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header Host $host;
proxy_set_header X-REAL-SCHEME $scheme;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-Proto $scheme;
access_log /etc/nginx/log/access.log;
error_log /etc/nginx/log/error.log;
}
}
When I try to access example.com.tr/app_1/ , I can access application but not all data.
I inspected this site and so many requests of application were failed.
All requests sended to example.com.tr/uri instead of example.com.tr/app_1/uri. How can I fix this ?
thanks,
You need a transparent path proxy setup. Means NGINX should use the requested URI without removing the matched location from it.
proxy_pass http://app_1;
Remove the tailing slash to tell NGINX not to do so. Using an upstream definition is great but make sure you apply keepalive.

Reverse proxy with nginx

I want to use reverse proxy with nginx to redirect/translate IP and port to some other IP and port. I was able to do that using the following code snippet inside http block of nginx.conf:
server {
listen 80;
server_name 13.88.1.1;
location / {
proxy_pass http://13.68.1.1:8888/;
index index.html index.htm;
} # end location
} # end server
Now the problem is that this is only usable for http requests. I have a scenario where I need to run an executable like 'uw.exe 13.88.1.1:80'. This is getting translated to 'uw.exe http://13.68.1.1:8888' but I want it to get translated to 'uw.exe 13.68.1.1:8888'. That is without the http because my app won't work with http. Does anybody know any simple solution to do that, preferably with nginx itself?
Update: This is no longer needed and cannot test it anymore. Thanks guys for chiming in. :)
Try this nginx configuration:
server {
listen 80;
location / {
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 $scheme;
proxy_set_header Connection '';
proxy_redirect off;
proxy_pass http://13.88.1.1:8888/;
}
}

Nginx directs request to www.example.com but not to internal web application

I've installed several web applications on different ports on the same server. From that server when I send an http request using wget or curl the request goes through and I get the response. I've set up nginx server to not have to specify the port each time. Here's the related nginx config:
server {
listen 10.0.223.34:80;
server_name app1.domain.com;
access_log /var/log/nginx/app1.domain.com.access.log;
error_log /var/log/nginx/app1.domain.com.error.log;
location / {
proxy_pass http://10.0.223.34:8080;
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;
}
}
If I try app1.domain.com from outside I get 502 Bad gateway error. But if I change the proxy_pass to http:\\www.example.com, then nginx takes me to the example.com website.
Inside the nginx.conf file I've specified user nginx;. I've tried changing it to root but it didn't help either. Do you have any idea what else I need to check?
Try this:
upstream app1 {
server localhost:8080;
}
server {
listen 10.0.223.34:
server_name app1.domain.com;
access_log /var/log/nginx/app1.domain.com.access.log;
error_log /var/log/nginx/app1.domain.com.error.log;
location / {
proxy_pass http://app1;
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;
}
}

Nginx wildcard reverse proxy to same name

I want nginx to take any requests from *.example.com and send them to the same name (*.example.com), just using nginx for SSL, and so that I can externally use my local DNS.
server {
listen *:80;
listen 443 ssl;
server_name *.whitefamilyserver.com;
location / {
proxy_pass http://$host; # (host will normally be subdomain.example.com)
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 $scheme;
}
}
So if someone went to test.example.com, it would forward it to test.example.com (but since this is running from inside my home network, it will use the local DNS to resolve the client).

Nginx server blocks

I'm trying to set my nginx to have 2 server blocks, one that lead to the default one atm and one that leads to my loadbalancer.
So I have set up my loadbalancer like this.
upstream backend {
server 192.168.24.28;
server 192.168.24.47;
}
server {
listen 80;
server_name MYURL
location / {
proxy_set_header HOST $host;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://backend;
proxy_redirect off;
}
}
and the default i have changed the listen to be
listen 192.168.24.30:80 default_server;
And the servers ip is 192.168.24.99
So if I understand it correctly, my settings should put the loadbalancer at 192.168.24.99 and the default at 192.168.24.30
So loadbalancer is placed correctly, but the 192.168.24.30 just gives me
ERR_CONNECTION_TIMED_OUT
Any idea what I might be doing wrong?
