Configurable transport parameters.
- integer parameters can be configured using the following directives:
quic_max_idle_timeout
quic_max_ack_delay
quic_max_packet_size
quic_initial_max_data
quic_initial_max_stream_data_bidi_local
quic_initial_max_stream_data_bidi_remote
quic_initial_max_stream_data_uni
quic_initial_max_streams_bidi
quic_initial_max_streams_uni
quic_ack_delay_exponent
quic_active_migration
quic_active_connection_id_limit
- only following parameters are actually sent:
active_connection_id_limit
initial_max_streams_uni
initial_max_streams_bidi
initial_max_stream_data_bidi_local
initial_max_stream_data_bidi_remote
initial_max_stream_data_uni
(other parameters are to be added into ngx_quic_create_transport_params()
function as needed, should be easy now)
- draft 24 and draft 27 are now supported
(at compile-time using quic_version macro)

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 ".Fl d Ar directives" .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 ".Cm reopen" -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 Same as .Fl t , but additionally dump configuration files to standard output. .It Fl t Do not run, just test the configuration file. .Nm checks the configuration file syntax and then tries to open files referenced in the configuration file. .It Fl V Print the .Nm version, compiler version, and .Pa configure script parameters. .It Fl v Print the .Nm version. .El .Sh SIGNALS The master process of .Nm can handle the following signals: .Pp .Bl -tag -width ".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 is no need to explicitly control worker processes normally, they support some signals too: .Pp .Bl -tag -width ".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 ENVIRONMENT The .Ev NGINX environment variable is used internally by .Nm and should not be set directly by the user. .Sh FILES .Bl -tag -width indent .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 Exit status is 0 on success, or 1 if the command fails. .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;" .Ed .Sh SEE ALSO .\"Xr nginx.conf 5 .\"Pp Documentation at .Pa http://nginx.org/en/docs/ . .Pp For questions and technical support, please refer to .Pa http://nginx.org/en/support.html . .Sh HISTORY Development of .Nm started in 2002, with the first public release on October 4, 2004. .Sh AUTHORS .An -nosplit .An Igor Sysoev Aq igor@sysoev.ru . .Pp This manual page was originally written by .An Sergey A. Osokin Aq osa@FreeBSD.org.ru as a result of compiling many .Nm documents from all over the world.
