The @code{(gnu services web)} module provides the nginx web server and
also a fastcgi wrapper daemon.
The @code{(gnu services web)} module provides the Apache HTTP Server,
the nginx web server, and also a fastcgi wrapper daemon.
@subsubheading Apache HTTP Server
@deffn {Scheme Variable} httpd-service-type
Service type for the @uref{https://httpd.apache.org/,Apache HTTP} server
(@dfn{httpd}). The value for this service type is a
@code{https-configuration} record.
A simple example configuration is given below.
@example
(service httpd-service-type
(httpd-configuration
(config
(httpd-config-file
(server-name "www.example.com")
(document-root "/srv/http/www.example.com")))))
@end example
Other services can also extend the @code{httpd-service-type} to add to
the configuration.
@example
(simple-service 'my-extra-server httpd-service-type
(list
(httpd-virtualhost
"*:80"
(list (string-append
"ServerName "www.example.com
DocumentRoot \"/srv/http/www.example.com\"")))))
@end example
@end deffn
The details for the @code{httpd-configuration}, @code{httpd-module},
@code{httpd-config-file} and @code{httpd-virtualhost} record types are
given below.
@deffn {Data Type} httpd-configuration
This data type represents the configuration for the httpd service.
@table @asis
@item @code{package} (default: @code{httpd})
The httpd package to use.
@item @code{pid-file} (default: @code{"/var/run/httpd"})
The pid file used by the shepherd-service.
@item @code{config} (default: @code{(httpd-config-file)})
The configuration file to use with the httpd service. The default value
is a @code{httpd-config-file} record, but this can also be a different
G-expression that generates a file, for example a @code{plain-file}. A
file outside of the store can also be specified through a string.
@end table
@end deffn
@deffn {Data Type} httpd-module
This data type represents a module for the httpd service.
@table @asis
@item @code{name}
The name of the module.
@item @code{file}
The file for the module. This can be relative to the httpd package being
used, the absolute location of a file, or a G-expression for a file
within the store, for example @code{(file-append mod-wsgi
"/modules/mod_wsgi.so")}.
@end table
@end deffn
@deffn {Data Type} httpd-config-file
This data type represents a configuration file for the httpd service.
@table @asis
@item @code{modules} (default: @code{%default-httpd-modules})
The modules to load. Additional modules can be added here, or loaded by
additional configuration.
@item @code{server-root} (default: @code{httpd})
The @code{ServerRoot} in the configuration file, defaults to the httpd
package. Directives including @code{Include} and @code{LoadModule} are
taken as relative to the server root.
@item @code{server-name} (default: @code{#f})
The @code{ServerName} in the configuration file, used to specify the
request scheme, hostname and port that the server uses to identify
itself.
This doesn't need to be set in the server config, and can be specifyed
in virtual hosts. The default is @code{#f} to not specify a
@code{ServerName}.
@item @code{document-root} (default: @code{"/srv/http"})
The @code{DocumentRoot} from which files will be served.
@item @code{listen} (default: @code{'("80")})
The list of values for the @code{Listen} directives in the config
file. The value should be a list of strings, when each string can
specify the port number to listen on, and optionally the IP address and
protocol to use.
@item @code{pid-file} (default: @code{"/var/run/httpd"})
The @code{PidFile} to use. This should match the @code{pid-file} set in
the @code{httpd-configuration} so that the Shepherd service is
configured correctly.
@item @code{error-log} (default: @code{"/var/log/httpd/error_log"})
The @code{ErrorLog} to which the server will log errors.
@item @code{user} (default: @code{"httpd"})
The @code{User} which the server will answer requests as.
@item @code{group} (default: @code{"httpd"})
The @code{Group} which the server will answer requests as.
@item @code{extra-config} (default: @code{(list "TypesConfig etc/httpd/mime.types")})
A flat list of strings and G-expressions which will be added to the end
of the configuration file.
Any values which the service is extended with will be appended to this
list.
@end table
@end deffn
@deffn {Data Type} httpd-virtualhost
This data type represents a virtualhost configuration block for the httpd service.
These should be added to the extra-config for the httpd-service.
@example
(simple-service 'my-extra-server httpd-service-type
(list
(httpd-virtualhost
"*:80"
(list (string-append
"ServerName "www.example.com
DocumentRoot \"/srv/http/www.example.com\"")))))
@end example
@table @asis
@item @code{addresses-and-ports}
The addresses and ports for the @code{VirtualHost} directive.
@item @code{contents}
The contents of the @code{VirtualHost} directive, this should be a list
of strings and G-expressions.
@end table
@end deffn
@subsubheading NGINX
@deffn {Scheme Variable} nginx-service-type
