The nginx (spelled ''engine x'') is an HTTP and reverse proxy server, as well as a mail proxy server. The nginx is known for its high performance, stability, rich feature set, simple configuration, and low resource consumption.
The options are as follows:
-? | -h' Print help.
-g directives Set global configuration directives. See EXAMPLES for details.
-p prefix' Set prefix path. Default value is %%PREFIX%%.
-q' Suppress non-error messages during configuration testing.
-s signal' Send signal to the master process. The argument signal can be one of: stop, quit, reopen, reload. The following table shows the corresponding system signals.
stop' SIGTERM quit' SIGQUIT reopen' SIGUSR1 reload' SIGHUP
-t' Don't run, just test the configuration file. The nginx checks configuration for correct syntax and then tries to open files referred in configuration.
-v' Print nginx version.
-V' Print nginx version, compiler version and configure script parameters.
The master process of nginx can handle the following signals.
SIGINT, SIGTERM' Shut down quickly.
While there's no need to explicitly control worker processes normally, they support some signals, too:
SIGTERM' Shut down quickly. SIGQUIT' Shut down gracefully. SIGUSR1' Reopen log files.
To enable a debugging log, reconfigure nginx to build with debugging:
and then set the debug level of the error_log:
It is also possible to enable the debugging for some IP address:
Exit status is 0 on success, or 1 if the command fails.
nginx -t -c ~/mynginx.conf -g "pid /var/run/mynginx.pid; worker_processes 2;"
