In my use case, I am trying to do a reverse proxy using nginx server. I have two applications running in two ports. For example app server is running port 9090 and api server is running in 8081.
I will be running nginx server in port in 8080. If I get /api request, nginx should redirect to api server. Other requests should go to app server.
I have the following nginx.conf,
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
upstream app {
server 127.0.0.1:9090;
keepalive 64;
}
upstream api {
server 127.0.0.1:8081;
keepalive 64;
}
#
# The default server
#
server {
listen 8080;
server_name howti;
location /api {
rewrite /api/(.*) /$1 break;
proxy_pass http://api;
proxy_redirect off;
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 Host $http_host;
proxy_set_header X-NginX-Proxy true;
real_ip_header X-Forwarded-For;
real_ip_recursive on;
#proxy_set_header Connection "";
#proxy_http_version 1.1;
}
location /{
rewrite /(.*) /$1 break;
proxy_pass http://app;
proxy_redirect off;
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 Host $http_host;
proxy_set_header X-NginX-Proxy true;
real_ip_header X-Forwarded-For;
real_ip_recursive on;
#proxy_set_header Connection "";
#proxy_http_version 1.1;
}
# redirect not found pages to the static page /404.html
error_page 404 /404.html;
location = /404.html {
root /usr/share/nginx/html;
}
# redirect server error pages to the static page /50x.html
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
}
}
But it is not working. I am not able to debug the request in nginx? Could someone help me with this? Thanks

I have alfresco 5.2 community edition installed on ubuntu machine with nginx as proxy. updated the SSL recently for my new domain. It is working fine and site is accessible through https://new.domain.com/share/
I want to redirect all http traffic to https://new.domain.com/share/. Tried changing the server config block but getting an error too many redirects .
currently new.domain.com is redirecting to https://new.domain.com/ and need to change it from new.domain.com to https://new.domain.com/share/

}
I have tried multiple way to fix the reverse proxy, but not getting any luck.
I followed the below url to fix the issue: https://github.com/noirbizarre/flask-restplus/issues/223
The nginx config is as follows:
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
server {
listen 80;
server_name localhost;
location / {
root html;
index index.html index.htm;
}
location /api {
proxy_pass http://localhost:5000; #change to your port
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 $scheme;
}
Add a rewrite clause to the api
rewrite ^/api/(.*) /$1 break;
In my use case, I would like to redirect www.xyz.com/static to www.abc.com using nginx as reverse proxy. I have the following nginx configuration in place,
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
keepalive_timeout 65;
client_max_body_size 500M;
#timeouts

proxy_send_timeout 600;
proxy_read_timeout 600;

upstream s-content {
server abc.com;
keepalive 64;
}
#
# The default server
#
server {
listen 80;
server_name rproxy;
location /static {
rewrite /(.*) /$1 break;
proxy_pass http://s-content;

This server proxy is mapped to xyz.com and listens on port 80. I would like to redirect to abc.com when I get a request in abc.com/static. But for some reasons the rewrite is not working.
Could someone help me on this. I appreciate the help.
I have an nginx on port 80 and a tomcat on port 8080 configured as upstream.
The war application in tomcat listen to /pwm.
I would like to configure nginx to a reverse proxy for tomcat and rewrite the url "/" to "/pwm".
example:
user types "web.noc.local" in browser and nginx rewrites the url to web.noc.local/pwm and redirects to tomcat on port 8080.
my nginx config:
upstream pwm_server {
server 127.0.0.1:8080 fail_timeout=0;
}
server {
listen 80;
server_name web.noc.local;
access_log /var/log/nginx/log/web.noc.local.access.log main;
error_log /var/log/nginx/log/web.noc.local.error.log;
location / {
if ($is_args != "") {
rewrite "^$" /pwm break;
expires 7d;
proxy_pass http://pwm_server;
}
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_max_temp_file_size 0;
proxy_buffering off;
proxy_connect_timeout 30;
proxy_send_timeout 30;
proxy_read_timeout 30;
proxy_pass http://pwm_server;
}
}
now when I open the url the, nothing happens, only a blank screen.
thx for help.
Ok, I found a solution for me:
location / {
rewrite ^ http://web.noc.local/pwm/ last;
}
location /pwm {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_max_temp_file_size 0;
proxy_buffering off;
proxy_connect_timeout 30;
proxy_send_timeout 30;
proxy_read_timeout 30;
proxy_pass http://pwm_server;
}
I am using the following configuration
upstream site {
server 127.0.0.1:3000;
keepalive 64;
}
server {
listen 80;
error_page 400 404 500 502 503 504 /50x.html;
location /50x.html {
internal;
root /usr/share/nginx/www;
}
location /static {
root /opt/site/static;
access_log off;
expires max;
}
location / {
proxy_redirect off;
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 Host $http_host;
proxy_set_header X-NginX-Proxy true;
proxy_set_header Connection "";
proxy_http_version 1.1;
proxy_pass http://site;
proxy_intercept_errors on;
}
}
I have saved it to /etc/nginx/sites-available/site.conf and symlinked to it /etc/sites-enabled/site.conf , and when I restart nginx it gives me the following error:
Restarting nginx: [emerg]: unknown directive "keepalive" in /etc/nginx/sites-enabled/site.conf:3
There are no keepalive directive. Use keepalive_timeout instead. And you can't put it inside upsream, use inside http, server or location.
Option "keepalive" is provided by keepalive module. And since 1.1.4 keepalive functionality is included in the main code.
