💡 Hint

Common Mistakes

Using 'error' level which shows only errors, not debug info.

Using 'info' which is less detailed than debug.

Setting the error_log level to debug enables detailed debug logging in nginx.

medium

Complete the code to enable debug mode for a specific nginx location block.

Nginx

location /test {
    [1] on;
}

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

Cproxy_debug

Ddebug

💡 Hint

Common Mistakes

Using 'debug' which is not a valid directive here.

Using 'proxy_debug' which does not exist.

The debug_connection directive enables debug logging for connections from specific IPs or all if set to 'all'.

Fix the error in the nginx debug log directive to correctly enable debug logging.

Nginx

💡 Hint

Common Mistakes

Leaving a log level before 'debug' causes syntax errors.

Using 'error' or 'warn' instead of 'off'.

The off keyword disables the default log level, allowing the explicit debug level to work correctly.

4fill in blank

hard

Fill both blanks to configure nginx to log debug messages only for connections from localhost.

Nginx

error_log /var/log/nginx/error.log [1];
debug_connection [2];

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

Call

D127.0.0.1

Attempts:

💡 Hint

Common Mistakes

Using 'all' in debug_connection logs debug for all connections.

Using 'info' instead of 'debug' for error_log.

Set error_log level to debug and debug_connection to 127.0.0.1 to enable debug logs only for localhost connections.

5fill in blank

hard

Fill all three blanks to create a map that enables debug logging only for requests from a specific IP.

Nginx

map $remote_addr $debug_mode {
    default [1];
    [2] [3];
}

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

Aoff

B192.168.1.100

Con

D127.0.0.1

Attempts:

3 left

💡 Hint

Common Mistakes

Setting default to 'on' enables debug for all IPs.

Mixing IP addresses or using 'all' instead of a specific IP.

This map sets debug_mode to off by default, but turns it on for the IP 192.168.1.100.
