-p prefix Set prefix path. Default value is /usr.
-q Suppress non-error messages during configuration testing.
-s signal Send a signal to the master process. The signal can be
one of: stop, quit, reopen, reload. The following table shows the corresponding system signals.
stop SIGTERMquit SIGQUITreopen SIGUSR1reload 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 the configure script parameters.
Nginx master process can handle the following signals.
SIGINT, SIGTERM Shut down promptly.
SIGHUP Reload the configuration, launch new worker process(es) using this new configuration,
while gracefully shutting down the old worker processes
SIGQUIT Shut down gracefully.
SIGUSR1 Reopen log files.
SIGUSR2 Upgrade nginx executable on the fly.
SIGWINCH Gracefully shutdown all worker processes.
Usually there's no need to explicitly control worker processes, nevertheless you can send them some signals:
SIGTERM Shut down worker processes promptly.
SIGQUIT Shut down worker processes gracefully.
SIGUSR1 Reopen log files.
To enable the debug log level, the configure script requires the
--with-debug option:
./configure --with-debug ...
and then set the debug level of the error_log:
error_log /path/to/log debug;
It is also possible to enable the debugging for a specific IP address, for example:
events {
debug_connection 127.0.0.1;
}
/etc/nginx Nginx configuration directory.
Exit status is 0 on success, or 1 on failure.
