NGINX(8)                  BSD System Manager's Manual                 NGINX(8)

NAME
     nginx -- HTTP and reverse proxy server, mail proxy server

SYNOPSIS
     nginx [-?hqTtVv] [-c file] [-g directives] [-p prefix] [-s signal]

DESCRIPTION
     nginx (pronounced ``engine x'') is an HTTP and reverse proxy server, as well as a mail proxy server.  It is
     known for its high performance, stability, rich feature set, simple configuration, and low resource consumption.

     The options are as follows:

     -?, -h         Print help.

     -c file        Use an alternative configuration file.

     -g directives  Set global configuration directives.  See EXAMPLES for details.

     -p prefix      Set the prefix path.  The default value is %%PREFIX%%.

     -q             Suppress non-error messages during configuration testing.

     -s signal      Send a 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             Do not run, just test the configuration file.  nginx checks the configuration file syntax and
                    then tries to open files referenced in the configuration file.

     -T             Same as -t, but additionally dump configuration files to standard output.

     -V             Print the nginx version, compiler version, and configure script parameters.

     -v             Print the nginx version.

SIGNALS
     The master process of nginx can handle the following signals:

     SIGINT, SIGTERM  Shut down quickly.
     SIGHUP           Reload configuration, start the new worker process with a new configuration, and gracefully
                      shut down old worker processes.
     SIGQUIT          Shut down gracefully.
     SIGUSR1          Reopen log files.
     SIGUSR2          Upgrade the nginx executable on the fly.
     SIGWINCH         Shut down worker processes gracefully.

     While there is 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.

DEBUGGING LOG
     To enable a debugging log, reconfigure nginx to build with debugging:

           ./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 particular IP address:

           events {
                   debug_connection 127.0.0.1;
           }



ENVIRONMENT
     The NGINX environment variable is used internally by nginx and should not be set directly by the user.

FILES
     %%PID_PATH%%
             Contains the process ID of nginx.  The contents of this file are not sensitive, so it can be world-read-
             able.

     %%CONF_PATH%%
             The main configuration file.

     %%ERROR_LOG_PATH%%
             Error log file.

EXIT STATUS
     Exit status is 0 on success, or 1 if the command fails.

EXAMPLES
     Test configuration file ~/mynginx.conf with global directives for PID and quantity of worker processes:

           nginx -t -c ~/mynginx.conf \
                   -g "pid /var/run/mynginx.pid; worker_processes 2;"
