I have a small app written with NodeJS and it is hosted in Google Cloud. I reserved a IP and I can access the front of app with IP.
The problem is, I have an admin panel witch it is a different Node instance. This has his own port and I want to access it via url, like: http://admin.11.111.11.11
I've using NGINX with Ubuntu 20.4
Config for admin it looks like:
server {
listen 80;
listen [::]:80;
#server_name admin.11.111.11.111/ www.admin.11.111.11.111/;
location / {
#proxy_pass http://127.0.0.1:2222;
}
}
and for front:
server {
listen 80 default_server;
listen [::]:80 default_server ipv6only=on;
server_name mydomain.com www.mydomain.com;
location / {
proxy_pass http://127.0.0.1:1111;
}
}
At this moment I can't transfer the domain. I must wait client to finish writing his content. The mydomain.com use an old CMS so we must wait to finish to transfer the content, so the new app it is accessible just through new IP.
Thank you for any hint!

No, this isn't possible admin.11.111.11.11 is not a valid hostname. You can't mix hostnames and IP addresses as the host like that. This whole premise is flawed... this isn't an Nginx problem.

I have a node application running on an ec2 instance. Node is running on port 5000. I want to access the api from remote.
this is nginx configuration file.
server {
root /var/www/html;
index index.html index.htm index.nginx-debian.html;
client_max_body_size 20M;
listen 80;
listen [::]:80;
location / {
proxy_pass http://127.0.0.1:5000;
}
location /nginx_status {
# Turn on stats
stub_status on;
access_log off;
}
}
when I try to curl using curl localhost/nginx_status
it returns
Active connections: 1
server accepts handled requests
11 11 12
Reading: 0 Writing: 1 Waiting: 0
Also when I try to access the IP in browser, it shows
Welcome to nginx!
If you see this page, the nginx web server is successfully installed and working. Further configuration is required.
For online documentation and support please refer to nginx.org.
Commercial support is available at nginx.com.
Thank you for using nginx.
But if I try to access the ip_address/nginx_status it shows 404 Error for example if I took IP address 123.456.789.098 in browser it shows the above mentioned message and if I took 123.456.789.098/nginx_status it will return 404 error. Even if I try curl ip_address/nginx_status it is also returning 404 error.
My question is, How can I access node application running on port 5000 from outside world?
unfortunately I only see part of your config, is there another server that listens to 80?
You don't use "default_server" for listen either, and without "server_name" I find it difficult to distinguish between them. So maybe another config with the server + port 80 as default_server takes effect. Check in your /etc/nginx/ folder which servers {..} all exist.
The proxy_pass looks correct, if the nodjs server is really listed there, check again whether it is really http or https scheme. For the correct protocol transmission of the proxy_pass.
But you should then add a control for the "stub_status" so that it is information that you do not entrust to everyone, for me it is the case that only one application has access to it internally and under another list what is not released on the internet:
server {
listen 127.0.0.1:10081 default_server;
location /flyingfish_status {
stub_status on;
access_log off;
allow 127.0.0.1;
deny all;
}
}
I'm curious what you find out! :)
I have a trading bot built with flask+gunicorn+nginx deployed on AWS EC2 which runs for 8 hours a day. Everytime I start the instance, the public IP changes which I need to update the server_name in nginx.conf.
Is there a way to update this daily with the help of a script or service? My conf file looks like this :
server{
listen 80;
server_name "public ip I need to change everyday";
location / {
.
.}
}
Thanks.
Since your Nginx configuration has only one server block, make that block the default block. It will capture all requests regardless of the server IP. Therefore, you don't need to specify an IP for the server_name directive.
server {
listen 80 default_server;
server_name _;
# Please put other settings below.
#...
}
For more information, visit the Server names document.
But It's working fine with public IP as below
And I have created a subdomain with route 53 and then assigned A record with instance public IP
But when I ping the domain and IP it's getting request time out and all packets were lost. My application is node express app.So please it's a huge favor if anyone can solve this issue.
From your screenshot, I found that you're using Nginx as a Reverse proxy. So it might be because of your Nginx config
example your Nginx config may look like this,
server {
listen 80;
server_name 192.168.1.21;
...
}
you've to update it to:
server {
listen 80;
server_name subdomain.domain.com;
...
}
I created a VM, port 80 is open and installed NGINX on it.
I created 2 App Services which can be accessed via x1.azurewebsites.net and x2.azurewebsites.net
I configured the VM to act as an load balancer but when redirecting the traffic I get the following: https://i.gyazo.com/b94bed9c90d3b0f0c400c83f762f0544.png
I am not using my own domain. Does someone know what the issue could be?
I got the following configurations:
upstream backend {
server xx.azurewebsites.net;
server xxx.azurewebsites.net;
}
server {
listen 80 default_server;
listen [::]:80 default_server;
root /var/www/html;
server_name_;
location / {
proxy_pass http://backend;
}
}
Azure App Service uses cookies for ARR (Application Request Routing). You have to make sure that your NGinx reverse proxy configuration pass the correct cookie / header to your web app.
The other possibility (to make sure the behavior comes from ARR) is to disable it: https://azure.microsoft.com/en-us/blog/disabling-arrs-instance-affinity-in-windows-azure-web-sites/
I am running two instances of node.js servers serving same code on two different port numbers on same machine. For example, one node.js process is running on port 8080 and other on port 1337.
I need to put nginx proxy in front of both these servers and route any request coming to to these servers.
The reason I want to do this is because lets say I have only one server. I need to change the code and restart the server and it takes nearly 1 minute for the server to restart. During this time, any requests coming to the server will return 502 Bad Gateway Error. I want to avoid this situation by running a replica of the same server.
Now I want to setup nginx in such a way that whenever either one of them is down (restarting while doing git pull), requests should be routed to the other one.
How can I accomplish this setting and where should I start reading about this ?
Requirement: suppose you have 2 application both running on different port at same machine.You have purchased only one domain and want to use it for multiple application.suppose below is the requirement.
purchased domain: example.com
app1_name/app1_port: app1/8081
app2_name/app2_port: app2/8082
You have two option here, you can choose any one you like
1st way: http://example.com/app1, http://example.com/app2
2nd way: http://app1.example.com, http://app2.example.com
Below are final configuration for both type
1st type using url resource indicator and multiple location
server{
listen 80;
server_name example.com;
location /app1{
proxy_pass http://localhost:8081;
}
location /app2{
proxy_pass http://localhost:8082;
}
}
2nd type using subdomain and multiple server block
server{
listen 80;
server_name example.com;
}
server{
server_name app1.example.com;
location /{
proxy_pass http://localhost:8081;
}
}
server{
server_name app2.example.com;
location /{
proxy_pass http://localhost:8082;
}
}
Note: Ideally nginx should run on port 80 and should mapped to main domain. So that you dont have to type port in browser as 80 is default port for http request. You might have to add additional configuration parameter, above is just for demo purpose.
