Where can I find the error logs of nginx, using FastCGI and Django?

Logs location on Linux servers:

Apache – /var/log/httpd/

IIS – C:\inetpub\wwwroot\

Node.js – /var/log/nodejs/

nginx – /var/log/nginx/

Passenger – /var/app/support/logs/

Puma – /var/log/puma/

Python – /opt/python/log/

Tomcat – /var/log/tomcat8

For Mac OS users, you can type nginx -help in your terminal.

nginx version: nginx/1.21.0
Usage: nginx [-?hvVtTq] [-s signal] [-p prefix]
             [-e filename] [-c filename] [-g directives]

Options:
  -?,-h         : this help
  -v            : show version and exit
  -V            : show version and configure options then exit
  -t            : test configuration and exit
  -T            : test configuration, dump it and exit
  -q            : suppress non-error messages during configuration testing
  -s signal     : send signal to a master process: stop, quit, reopen, reload
  -p prefix     : set prefix path (default: /opt/homebrew/Cellar/nginx/1.21.0/)
  -e filename   : set error log file (default: /opt/homebrew/var/log/nginx/error.log)
  -c filename   : set configuration file (default: /opt/homebrew/etc/nginx/nginx.conf)
  -g directives : set global directives out of configuration file

Then, you could find some default path for configuration and log files, in this case:

/opt/homebrew/log/nginx/error.log

It is a good practice to set where the access log should be in nginx configuring file . Using acces_log /path/ Like this.

keyval $remote_addr:$http_user_agent $seen zone=clients;

server { listen 443 ssl;

ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers   HIGH:!aNULL:!MD5;

if ($seen = "") {
    set $seen  1;
    set $logme 1;
}
access_log  /tmp/sslparams.log sslparams if=$logme;
error_log  /pathtolog/error.log;
# ...
}

I found it in /usr/local/nginx/logs/*.
