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 /usr/share/nginx.

       -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

       /run/nginx.pid
               Contains  the  process  ID  of  nginx.  The contents of this file are not sensitive, so it can be
               world-readable.

       /etc/nginx/nginx.conf
               The main configuration file.

       /var/log/nginx/error.log
               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;"
