the optimized HTTP/1.x, HTTP/2 server

Configure > Quick Start

In order to run the H2O standalone HTTP server, you need to write a configuration file. The minimal configuration file looks like as follows.

  port: 8080
user: nobody
        file.dir: /path/to/the/public-files
access-log: /path/to/the/access-log
error-log: /path/to/the/error-log
pid-file: /path/to/the/pid-file

The configuration instructs the server to:

  1. listen to port 8080
  2. under the privileges of nobody
  3. serve files under /path/to/the/public-files
  4. emit access logs to file: /path/to/the/access-log
  5. emit error logs to /path/to/the/error-log
  6. store the process id of the server in /path/to/the/pid-file

Enter the command below to start the server.

% sudo h2o -m daemon -c /path/to/the/configuration-file

The command instructs the server to read the configuration file, and start in daemon mode, which dispatches a pair of master and worker processes that serves the HTTP requests.

To stop the server, send SIGTERM to the server.

% sudo kill -TERM `cat /path/to/the/pid-file`

Next Step

Now that you know how to start and stop the server, the next step is to learn the configuration directives and their structure, or see the configuration examples.
