I'm using Django with FastCGI + nginx. Where are the logs (errors) stored in this case?

Errors are stored in the nginx log file. You can specify it in the root of the nginx configuration file:
error_log /var/log/nginx/nginx_error.log warn; On Mac OS X with Homebrew, the log file was found by default at the following location:
/usr/local/var/log/nginx I was looking for a different solution.
Error logs, by default, before any configuration is set, on my system (x86 Arch Linux), was found in:
/var/log/nginx/error.log You can use lsof (list of open files) in most cases to find open log files without knowing the configuration.
Example:
Find the PID of httpd (the same concept applies for nginx and other programs):
$ ps aux | grep httpd ... root 17970 0.0 0.3 495964 64388 ? Ssl Oct29 3:45 /usr/sbin/httpd ... Then search for open log files using lsof with the PID:
$ lsof -p 17970 | grep log httpd 17970 root 2w REG 253,15 2278 6723 /var/log/httpd/error_log httpd 17970 root 12w REG 253,15 0 1387 /var/log/httpd/access_log If lsof prints nothing, even though you expected the log files to be found, issue the same command using sudo.

4Run this command, to check error logs:
tail -f /var/log/nginx/error.log My ngninx logs are located here:
/usr/local/var/log/nginx/* You can also check your nginx.conf to see if you have any directives dumping to custom log.
run nginx -t to locate your nginx.conf.
# in ngingx.conf error_log /usr/local/var/log/nginx/error.log; error_log /usr/local/var/log/nginx/error.log notice; error_log /usr/local/var/log/nginx/error.log info; Nginx is usually set up in /usr/local or /etc/. The server could be configured to dump logs to /var/log as well.
If you have an alternate location for your nginx install and all else fails, you could use the find command to locate your file of choice.
find /usr/ -path "*/nginx/*" -type f -name '*.log', where /usr/ is the folder you wish to start searching from.
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 Type this command in the terminal:
sudo cat /var/log/nginx/error.log cd /var/log/nginx/ cat error.log 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/*.
