.Sh NAME
.Nm nginx
.Nd HTTP and reverse proxy server, mail proxy server
.Sh SYNOPSIS
.Nm
.Op Fl ?hqtuVv
.Op Fl c Ar file
.Op Fl g Ar directives
.Op Fl p Ar prefix
.Op Fl s Ar signal
.Sh DESCRIPTION
.Nm
(pronounced
.Dq 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.
.Pp
The options are as follows:
.Bl -tag -width Ds
.It Fl ?\& | h
Print help.
.It Fl c Ar file
Use an alternative configuration
.Ar file .
.It Fl g Ar directives
Set global configuration directives.
See
.Sx EXAMPLES
for details.
.It Fl p Ar prefix
Set the prefix path.
The default value is
.Pa %%PREFIX%% .
.It Fl q
Suppress non-error messages during configuration testing.
.It Fl s Ar signal
Send a signal to the master process.
The argument
.Ar signal
can be one of:
.Cm stop , quit , reopen , reload .
The following table shows the corresponding system signals.
.Pp
.Bl -tag -width ".It Cm reopen" -offset indent -compact
.It Cm stop
.Dv SIGTERM
.It Cm quit
.Dv SIGQUIT
.It Cm reopen
.Dv SIGUSR1
.It Cm reload
.Dv SIGHUP
.El
.It Fl t
Don't run, just test the configuration file.
.Nm
checks the configuration file syntax and then tries to open any files
referred to in the configuration file.
.It Fl u
By default
.Nm
will
.Xr chroot 2
to the home directory of the user running the daemon,
typically
.Dq www ,
or to the home directory of
.Ic user
in
.Pa nginx.conf .
The
.Fl u
option disables this behaviour, and returns
.Nm
to the original "unsecure" behaviour.
.It Fl V
Print the
.Nm
version, compiler version, and
.Pa configure
script parameters.
.It Fl v
Print the
.Nm
version.
.El
.Pp
The master process of
.Nm
can handle the following signals.
.Pp
.Bl -tag -width ".It Dv SIGINT , SIGTERM" -compact
.It Dv SIGINT , SIGTERM
Shut down quickly.
.It Dv SIGHUP
Reload configuration, start the new worker process with a new
configuration, and gracefully shut down old worker processes.
.It Dv SIGQUIT
Shut down gracefully.
.It Dv SIGUSR1
Reopen log files.
.It Dv SIGUSR2
Upgrade the
.Nm
executable on the fly.
.It Dv SIGWINCH
Shut down worker processes gracefully.
.El
.Pp
While there's no need to explicitly control worker processes normally,
they support some signals too:
.Pp
.Bl -tag -width ".It Dv SIGINT , SIGTERM" -compact
.It Dv SIGTERM
Shut down quickly.
.It Dv SIGQUIT
Shut down gracefully.
.It Dv SIGUSR1
Reopen log files.
.El
.Sh DEBUGGING LOG
To enable a debugging log, reconfigure
.Nm
to build with debugging:
.Pp
.Dl "./configure --with-debug ..."
.Pp
and then set the
.Cm debug
level of the
.Va error_log :
.Pp
.Dl "error_log /path/to/log debug;"
.Pp
It is also possible to enable the debugging for a particular IP address:
.Bd -literal -offset indent
events {
debug_connection 127.0.0.1;
}
.Ed
.Sh FILES
.Bl -tag -width indent -compact
.It Pa %%PID_PATH%%
Contains the process ID of
.Nm .
The contents of this file are not sensitive, so it can be world-readable.
.It Pa %%CONF_PATH%%
The main configuration file.
.It Pa %%ERROR_LOG_PATH%%
Error log file.
.El
.Sh EXIT STATUS
.Ex -std nginx
.Sh EXAMPLES
Test configuration file
.Pa ~/mynginx.conf
with global directives for PID and quantity of worker processes:
.Bd -literal -offset indent
nginx -t -c ~/mynginx.conf \e
-g "pid /var/run/mynginx.pid; worker_processes 2;"
