## NAME
       nginx — HTTP and reverse proxy server, mail proxy server

## SYNOPSIS
       **nginx **[**-?hqTtVv**] [**-c _**file_] [**-e _**file_] [**-g _**directives_] [**-p _**prefix_] [**-s _**signal_]

## DESCRIPTION
       **nginx **(pronounced “engine x”) is an HTTP and reverse proxy server, a mail proxy server, and a
       generic  TCP/UDP 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 _

### -e _
                      standard error output should be used.

### -g _

### -p _

### -q             

### -s _
                      **quit**, **reopen**, **reload**.  The following table shows the corresponding system sig‐
                      nals:

                      **stop    **SIGTERM
                      **quit    **SIGQUIT
                      **reopen  **SIGUSR1
                      **reload  **SIGHUP

### -T              -t

### -t             
                      file syntax and then tries to open files referenced in the configuration file.

### -V             

### -v             

## 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.

       _stderr_  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;"
