Solution for Cape Town task from URL: https://sadservers.com/scenario/capetown

After logging into the server, there is no working nginx.

Examine details on why nginx does not work show me the first line containing ";". So I removed ";" from the nginx file and nginx does not yet work.

After examining the error log - I was able to see and spot file limits.

After viewing /proc/[pid]/limits - I spot this (Max open files 10)

I did check limits for user www-data, as well as other things (fs.file-max, others)

In the end - Maybe systemD has some limitations per process.

After reading the .service file from systemD

Add # on the start of the line, reload the system daemon, and restart nginx and it works!

The task was to find out how to run a web server on port 80 and to check if is working properly. URL: https://sadservers.com/scenario/tokyo

After checking logs (apache, systems, etc) and finally running iptables - saw HTTP blocked in iptables. So running iptables -F solve this issue (I also added a path for apache /var/www/html/ inside of apache.conf FYI)
