Common Mistakes

Using port 443 for HTTP instead of HTTPS

Using SSH port 22 by mistake

The default port for HTTP traffic in Nginx is 80. This is where the web server listens for incoming requests.

💡 Hint

Common Mistakes

Using port 80 which is for web server

Using SSH port 22

The application server is running on port 3000, so Nginx forwards requests to that port.

💡 Hint

Common Mistakes

Using slash '/' instead of colon

Missing colon causes syntax error

The proxy_pass URL must have a colon ':' before the port number to specify the port.

💡 Hint

Common Mistakes

Using '/' instead of ':' for port

Using undefined cache zone name

Use ':' before the port number and specify the cache zone name 'my_cache' for proxy_cache.

5fill in blank

hard

Fill both blanks to configure Nginx to serve static files and proxy API requests.

Nginx

server {
    listen 80;
    location /static/ {
        root [1];
    }
    location /api/ {
        proxy_pass http://127.0.0.1:3000/;
        proxy_set_header Host [2];
    }
}

Drag options to blanks, or click blank then click option'

A/var/www/html

B:

C$host

D/usr/local/nginx/html

💡 Hint

Common Mistakes

Wrong root path for static files

Missing colon before port

Incorrect Host header value

Static files are served from '/var/www/html'. The proxy_pass needs ':' before port 3000. The Host header is set to '$host' to pass the original host.
