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.
