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.
