@subsubsection Web Services
The @code{(gnu services web)} module provides the following service:
@deffn {Monadic Procedure} nginx-service [#:nginx nginx] @
[#:log-directory ``/var/log/nginx''] @
[#:run-directory ``/var/run/nginx''] @
[#:config-file]
Return a service that runs @var{nginx}, the nginx web server.
The nginx daemon loads its runtime configuration from @var{config-file}.
Log files are written to @var{log-directory} and temporary runtime data
files are written to @var{run-directory}. For proper operation, these
arguments should match what is in @var{config-file} to ensure that the
directories are created when the service is activated.
