Lets say I have corporatewebsite.com listening on port 80. Which is an appache / WordPress site.
I have a node application that I'd like to respond to sub.corporatewebsite.com
The node application is running Express currently. I can get it to listen to a separate port at the moment, but my service won't start if it's pointed to port 80 since it's already in use.
How can I have both apache and node listening to port 80, but having node responding to the subdomain?
You could use a reverse proxy like Nginx to route your subdomains.
Here is an example of nginx configuration, you might probaly have to complete according to your project and server :
server {
listen 80;
server_name corporatewebsite.com;
location / {
[ ... some parameters ... ]
include proxy_params; // Import global configuration for your routes
proxy_pass http://localhost:1234/; // One of your server that listens to 1234
}
}
server {
listen 80;
server_name sub.corporatewebsite.com;
location / {
[ ... some parameters ... ]
include proxy_params;
proxy_pass http://localhost:4567/; // The other server that listens to 4567
}
}
You have to configure, for example, apache2 listening to port 1234 while nodejs is listening to port 4567.
If you do like this, a good practice is to block direct access from the outside to your ports 1234 and 4567 (using iptables for example).

I am trying to use nginx to direct a website hosted on port 8080 to domain exemple1.com and another one on port 8081 that i want to redirect to domain exemple2.com.
On the file /etc/nginx/sites-available/default i puted this code:
location ~/example1/ {
proxy_pass http://example1.com;
}
location ~/example2/ {
proxy_pass http://example2.com;
}
but i couldn make it work . I am running 2 nodejs servers on the ports i talked about (port 8080 and 8081).
What i am doing wrong and how to "fix "
it?
Because the downstream app server running on different ports(listen) than coming in, you need to specify ports in proxy_pass. So I think
listen 8080;
location ~/example1/ {
proxy_pass http://example1.com:8080;
}
location ~/example2/ {
proxy_pass http://example2.com:8081;
}
I have a node process listening on port 11180, and would like to redirect all request from https:example.com:11179 to it. How can I accomplish this with nginx ?
I cannot use port 443, because it is forwarding to a different process. However I do have a certificate for the domain example.com
I have tried using this configuration
server {
listen 11179 ssl
location / {
proxy_pass http://127.0.0.1:11180
...
}
}
but the site just keeps loading, however the same configuration works if i listen on port 443
server {
listen 443 ssl
location / {
proxy_pass http://127.0.0.1:11180
...
}
}
Thanks a bunch for your help
Turns out it was a firewall problem :P
I've got nginx to run my (node.js/react) application on the server. But I can't seem to connect to the database.
In the nginx.conf file I've added the following inside http.
http {
...
server {
listen 80;
server_name localhost;
...}
...}
And above the http section I have the following,
stream {
server {
listen 4000;
proxy_connect_timeout 1s;
proxy_timeout 3s;
proxy_pass stream_mongo_backend;
}
upstream stream_mongo_backend {
server 127.0.0.1:27017;
}
}
I start the nginx server, the application runs on localhost, opens up the login page but I can't login because it's still not connected to the database (mongodb).
I'm not sure if I've got my port numbers wrong or if I'm missing some configuration line inside nginx.conf.
EDIT: Ok, I had it wrong before. I wasn't supposed to connect to mongodb at this point. I was supposed to connect to the backend server of my application which would run at 4000. So now I've added a new location for /api/ inside http and proxied all requests to 4000. I still have one question though. I have to run my backend server separately for this to work. For the frontend I've created a folder and put all my build files in there so nginx starts up the webserver from there. Doing the same for the backend did not start up the server. Is there a way to get nginx to start the backend server as well?
Also can I get the frontend to run directly without the build files ? Like node would with npm start?
the port number is right. try to open up a mongo shell and see if you are able to access a mongo instance. if not, you will need to run sudo service mongodb start to start it up.
Guess it's knida late but you don't need to setup nginx for your backend to connect local mongodb.
And you need to run the frontend and backend server first by yarn start, node run or something like that if you want to run it without build files.
And then bypass the calls from 80 port to the local host servers.
For example, your FE run at 3000 port, BE run at 5000 port.
Then your nginx should be:
http {
...
server {
listen 80;
server_name localhost;
location /api/ {
proxy_pass localhost:5000;
}
location / {
proxy_pass localhost:3000;
}
...}
...}
I'm trying to set up upstream servers with nginx. All run the same Node.js app on port 8080 with pm2. Here is the nginx default.conf of the main server
upstream backend {
ip_hash;
server localhost:8080;
server sv1_ip_address;
server sv2_ip_address;
}
server {
listen 443 ssl;
location / {
proxy_pass http://backend;
...
}
...
}
And on sv1 and sv2, I have the same default.conf as follows
server {
listen 80 default_server;
location / {
proxy_pass http://localhost:8080;
...
}
}
Now when I tried shutting down either sv1 or sv2 (using pm2 kill for Node or even reboot), all upstream servers went down and I receive a 500 error (?) when accessing the app by the domain name. So I thought there was something wrong with nginx on those secondary servers and I replaced upstream backend with this
upstream backend {
ip_hash;
server localhost:8080;
server sv1_ip_address:8080;
server sv2_ip_address:8080;
}
and now shutting down or rebooting were handled correctly (meaning nginx will route the requests to one of the living servers). Is this an expected behavior, or am I doing something wrong here? I don't think routing requests directly to port 8080 is a good idea though.
I donot know why you had to install nginx service on sv1 and sv2 servers.
When you reboot sv1 , sv2 servers, it should be enabling nginx first. Please check service nginx status is running or not once reboot is done.
And you kill node meaning application is down, so you got 500 error on nginx
Hi guys i have a problem. I work with php and node, php works with nginx listening port 80 and node works with the port 3000. I want add a subdomain that listen port 3000 a like media.mydomain.com but i could not. I tried with my website register domain and nothing happened and then with nginx in virtual host but show in console error because this port it is using.
nginx-php=mydomain.com
node=mydomain.com:3000 (tried add subdomain "media.fotogena.co")
virtual host:
server {
server_name media.mydomain.com;
listen mydomain.com:3000;
#i don't know that do!
}#show error port is being used
and had seen something like upstream but this assign port 80 to port 3000 but don't is the that me need
If i understand what you want to do, you want a subdomain to use instead of the port 3000, for the subdomain to work you need it to listen on port 80, and proxy what ever comes to port 3000.
server {
server_name sub.example.com;
listen 80;
location / {
proxy_pass http://localhost:3000;
}
}
