Here is a URL : http://123.com/stat/api/abc?a=123
if I want to set proxy pass to : http://456.com/api/abc?a=123
My nginx config as below :
server {
listen 80;
server_name 123.com;
location /stat {
proxy_pass http://456.com;
}
}
And this is not work.
Any ideas?
Finally, I found the solution.
The final config as below :
location /stat/ {
proxy_pass http://456.com/;
}
the end of slash in location section and proxy_pass section must be have.

So I currently have a site at http://www.example.com and I would like that all requests from
http://www.example.com/api/v2/<anything>
to be proxied to
http://api.v2.com/<anything>
Note that http://api.v2.com does not have a base path.
My config:
server {
listen 80;
server_name www.example.com;
location /api/v2/ {
proxy_pass http://api.v2.com;
}
location / {
index index.html;
root /var/www/example.com/htdocs;
}
}
This way, however, the requests are being proxies to http://api.v2.com/api/v2/<anything> keeping the original path, and not http://api.v2.com/<anything>.
I've already noticed that:
location /api/v2 {
proxy_pass http://api.v2.com/api;
works as desired - http://api.v2.com/api/v2/<anything> proxies to http://api.v2.com/api/<anything>.
Is there a way to achieve the first behavior (that is , http://api.v2.com/api/v2/<anything> to http://api.v2.com/<anything>)? Do I have to use a rewrite? I know it it related to normalized URIs and that is expected, just would like to know if there's a way to do it.
If you want to remove the proxy path from resulting url to the server, either you should have the uri part in the proxy url, or you should specify the rewrite part.
In this specific case, it should be like as follows,
location /api/v2/ {
rewrite /api/v2/(.*) /$1 break;
proxy_pass http://api.v2.com/;
}
for more information visit nginx documentation https://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_pass
If the proxy_pass directive is specified with a URI, then when a request is passed to the server, the part of a normalized request URI matching the location is replaced by a URI specified in the directive.
server {
listen 80;
server_name www.example.com;
location /api/v2/ {
proxy_pass http://api.v2.com/;
}
location / {
index index.html;
root /var/www/example.com/htdocs;
}
}

Basically I have a problem when I try to redirect http://localhost/report I would like that it redirects to my app that has a route / but instead I get Cannot GET /report/
What do I have to add to my nginx.conf?
Here is it:
http {
upstream nodeapp {
server 127.0.0.1:9876;
keepalive 64;
}
server {
listen 80;
location /report {
proxy_pass http://nodeapp;
}
}
}
location /report/ {
# this slash ^ and this V
proxy_pass http://nodeapp/;
}
Read documentation on proxy_pass and location.
i am currently in situation where i need to get/catch sub-domain and pass that sub-domain value to proxy_pass in Nginx config.
e.g.
if user enters
http://google.com.mydomain.com
then it should do proxy pass as
proxy_pass http://www.google.com/;
in above example google.com is sub-domain
can this be doable ?
How can i achieve something like that in nginx ?
currently i am using configuration where sub-domain values are hard-coded in config files , but there are many sub-domains , so i need to do it like this way, but don't know correct syntax.
server {
listen 80;
server_name subdomain.domain.com;
charset utf-8;
location / {
proxy_pass http://www.subdomain/;
}
}
I am using * as A record to redirect all sub-domains to my web-host, i.e. wildcard DNS.
update:
i have found code snippet from https://stackoverflow.com/a/22774520/1642018
server {
listen 80;
# this matches every subdomain of domain.
server_name .domain.com;
location / {
set $subdomain "";
if ($host ~* "^(.+)\.domain.com$") {
set $subdomain $1;
}
proxy_pass http://$subdomain;
}
}
but the request is showing my default page which is in my default web root.
Two things.
1- A resolver (a dns server for your nginx in order to resolve google.com, you may add at your hosts or you are able to add resolver statement)
2- You will need to resolve how your client will deals with different domains, I mean google.com is different than google.com.ar or google.fr)
At this example I made work it for your example google.com
worker_processes 4;
error_log /var/log/nginx/error.log;
events {
worker_connections 1024;
}
http {
server {
listen 80;
location / {
set $subdomain "";
if ($host ~* "^(.+)\.domain.com$") {
set $subdomain $1;
}
resolver 8.8.8.8;
proxy_pass "http://$subdomain.com";
}
}
}
I hope that this configuration helps to you.
I would capture the subdomain using a map then proxy pass if the variable is defined:
map $host $subdomain {
~^(?<sub>.+)\.[^\.]+\.[^\.]+$ $sub;
}
server {
listen 80 default_server;
server_name _;
location / {
if ($subdomain) {
proxy_pass http://$subdomain;
}
}
}
I have an Nginx instance set up with a reverse proxy like so:
server {
listen 80;
server_name sitep-rate00.sv.walmartlabs.com;
location / {
proxy_pass http://www.example.com;
}
}
How can I set the css style sheet to a specific version, for example something like:
Substitute 's|styles/sheets.1.1.1(.*)\.css"|styles/sheets.1.1.33.css"|i'
If you are planning to proxy pass it too you can try a rewrite before the proxy pass
location / {
rewrite /styles/sheets.1.1.1(.*)\.css /styles/sheets.1.1.33.css last;
proxy_pass example.com;
}
I need to proxy a couple of urls to different hosts. Actually, I'm using the same host with different port to test my nginx configuration. This is my virtual host definition:
server {
listen 8081;
server_name domain.com;
location /Plasmid/ {
proxy_pass http://localhost:8000/Plasmid/;
}
location /_community/ {
proxy_pass http://localhost:8082/comments_api/ ;
}
location / {
# rewrite cq_user_authenticated===(.*)/(.*)/iuuid=(.*)/commenti.html$ /Plasmid/comments/legacy/$3/$1 ;
# rewrite querystring===(.*)$ /Plasmid/comments/legacy/$1 ;
# rewrite cq_user_authenticated===([^&]*)&/.*uuid=([^/]*) /comments_api/legacy/$2 ;
# rewrite userdetails(.*) /Plasmid/comments/user_details ;
root html;
index index.html index.htm;
}
}
Of course my hosts file has mapping for the domain.com
When I call the url: http://domain.com:8081/Plasmid/default/page/12 I get an http 404
If I remove the second location from my configuration:
location /_community/ {
proxy_pass http://localhost:8082/comments_api/ ;
}
I get the resource I want, but some part are missed since the are hosted on a different platform:
[error] 1033#0: *1 open() "/usr/local/Cellar/nginx/1.2.6/html/_community/content
How can I resolve this issue?
Do a little change:
location ^~ /Plasmid/ {
proxy_pass http://localhost:8000/Plasmid/;
}
location ^~ /_comunity/ {
proxy_pass http://localhost:8082/comments_api/;
Why is that? Because ^~ means starts with and when you request for page:
http://domain.com:8081/Plasmid/default/page/12
it fit to that rule. In your configuration you are using no mark and something like this:
location /anylocation
and it looks like your nginx prefer rule
location / {
than
location /Plasmid
and
location /_comunity
because it's using root directive and searching for _community/content in html folder (as you get in error message).
In other words ^~ has greater priority than no mark. One thing that could also help is to add break directive after each proxy_pass directive;
