Hello,
I have two Node.js applications running on ports 3000 and 3001:
Code:
# nc -zv 127.0.0.1 3000
localhost [127.0.0.1] 3000 (?) open
# nc -zv 127.0.0.1 3001
localhost [127.0.0.1] 3001 (?) open
Nginx configuration is as follows:
Code:
server {
server_name server1;
listen 80;
error_log /var/log/nginx/error.system-default.log;
access_log /var/log/nginx/access.system-default.log;
charset utf-8;
location / {
proxy_pass http://localhost:3000;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
}
server {
server_name server2;
listen 80;
error_log /var/log/nginx/error.system-default.log;
access_log /var/log/nginx/access.system-default.log;
charset utf-8;
location / {
proxy_pass http://localhost:3001;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
}
I tried to see these applications:
Code:
# curl localhost
<html>
<head><title>502 Bad Gateway</title></head>
<body>
<center><h1>502 Bad Gateway</h1></center>
<hr><center>nginx/1.25.4</center>
</body>
</html>
What is wrong? If I use
curl localhost:3000, then the file will be executed from Node.js and not Nginx!
Thank you.
