NAME
h2o - optimized HTTP/1.x, HTTP/2 server
SYNOPSIS
h2o [options]
DESCRIPTION
H2O is a performance-optimized HTTP/1.x and HTTP/2 web server. Designed from ground-up, the server takes
full advantage of HTTP/2 features including prioritized content serving and server push.
This manual page describes the options supported by the h2o command. Note that H2O should in most cases
be run as a system service (through a systemd(1) service or an initscript).
OPTIONS
-c, --conf FILE
Configuration file (default: /etc/h2o/h2o.conf)
-m, --mode mode
mode specifies one of the following modes:
worker the h2o process will stay in the foreground and handle all incoming connections itself
(default).
master h2o will be started using the /usr/share/h2o/start_server helper; in this mode the
start_server process will stay in the foreground and spawn an h2o worker process for
handling incoming connections. SIGHUP can be sent to the master process to reconfigure or
upgrade the server without service downtime.
daemon spawns a master process in the background and exits. error-log must be configured when
using this mode, as all errors are logged to the error log instead of output to standard
error.
test tests the configuration and exits
-t, --test
Synonym of `--mode=test`
-v, --version
Prints the version number
-h, --help
Prints usage help.
