@cindex php-fpm
PHP-FPM (FastCGI Process Manager) is an alternative PHP FastCGI implementation
with some additional features useful for sites of any size.
These features include:
@itemize @bullet
@item Adaptive process spawning
@item Basic statistics (similar to Apache's mod_status)
@item Advanced process management with graceful stop/start
@item Ability to start workers with different uid/gid/chroot/environment
and different php.ini (replaces safe_mode)
@item Stdout & stderr logging
@item Emergency restart in case of accidental opcode cache destruction
@item Accelerated upload support
@item Support for a "slowlog"
@item Enhancements to FastCGI, such as fastcgi_finish_request() -
a special function to finish request & flush all data while continuing to do
something time-consuming (video converting, stats processing, etc.)
@end itemize
... and much more.
@defvr {Scheme Variable} php-fpm-service-type
A Service type for @code{php-fpm}.
@end defvr
@deftp {Data Type} php-fpm-configuration
Data Type for php-fpm service configuration.
@table @asis
@item @code{php} (default: @code{php})
The php package to use.
@item @code{socket} (default: @code{(string-append "/var/run/php" (version-major (package-version php)) "-fpm.sock")})
The address on which to accept FastCGI requests. Valid syntaxes are:
@table @asis
@item @code{"ip.add.re.ss:port"}
Listen on a TCP socket to a specific address on a specific port.
@item @code{"port"}
Listen on a TCP socket to all addresses on a specific port.
@item @code{"/path/to/unix/socket"}
Listen on a unix socket.
@end table
@item @code{user} (default: @code{php-fpm})
User who will own the php worker processes.
@item @code{group} (default: @code{php-fpm})
Group of the worker processes.
@item @code{socket-user} (default: @code{php-fpm})
User who can speak to the php-fpm socket.
@item @code{socket-group} (default: @code{php-fpm})
Group that can speak to the php-fpm socket.
@item @code{pid-file} (default: @code{(string-append "/var/run/php" (version-major (package-version php)) "-fpm.pid")})
The process id of the php-fpm process is written to this file
once the service has started.
@item @code{log-file} (default: @code{(string-append "/var/log/php" (version-major (package-version php)) "-fpm.log")})
Log for the php-fpm master process.
@item @code{process-manager} (default: @code{(php-fpm-dynamic-process-manager-configuration)})
Detailed settings for the php-fpm process manager.
Must be either:
@table @asis
@item @code{<php-fpm-dynamic-process-manager-configuration>}
@item @code{<php-fpm-static-process-manager-configuration>}
@item @code{<php-fpm-on-demand-process-manager-configuration>}
@end table
@item @code{display-errors} (default @code{#f})
Determines wether php errors and warning should be sent to clients
and displayed in their browsers.
This is useful for local php development, but a security risk for public sites,
as error messages can reveal passwords and personal data.
@item @code{workers-logfile} (default @code{(string-append "/var/log/php" (version-major (package-version php)) "-fpm.www.log")})
This file will log the @code{stderr} outputs of php worker processes.
Can be set to @code{#f} to disable logging.
@item @code{file} (default @code{#f})
An optional override of the whole configuration.
You can use the @code{mixed-text-file} function or an absolute filepath for it.
@end table
@end deftp
@deftp {Data type} php-fpm-dynamic-process-manager-configuration
Data Type for the @code{dynamic} php-fpm process manager. With the
@code{dynamic} process manager, spare worker processes are kept around
based on it's configured limits.
@table @asis
@item @code{max-children} (default: @code{5})
Maximum of worker processes.
@item @code{start-servers} (default: @code{2})
How many worker processes should be started on start-up.
@item @code{min-spare-servers} (default: @code{1})
How many spare worker processes should be kept around at minimum.
@item @code{max-spare-servers} (default: @code{3})
How many spare worker processes should be kept around at maximum.
@end table
@end deftp
@deftp {Data type} php-fpm-static-process-manager-configuration
Data Type for the @code{static} php-fpm process manager. With the
@code{static} process manager, an unchanging number of worker processes
are created.
@table @asis
@item @code{max-children} (default: @code{5})
Maximum of worker processes.
@end table
@end deftp
@deftp {Data type} php-fpm-on-demand-process-manager-configuration
Data Type for the @code{on-demand} php-fpm process manager. With the
@code{on-demand} process manager, worker processes are only created as
requests arrive.
@table @asis
@item @code{max-children} (default: @code{5})
Maximum of worker processes.
@item @code{process-idle-timeout} (default: @code{10})
The time in seconds after which a process with no requests is killed.
@end table
@end deftp
@deffn {Scheme Procedure} nginx-php-fpm-location @
[#:nginx-package nginx] @
[socket (string-append "/var/run/php" @
(version-major (package-version php)) @
"-fpm.sock")]
A helper function to quickly add php to an @code{nginx-server-configuration}.
@end deffn
A simple services setup for nginx with php can look like this:
@example
(services (cons* (dhcp-client-service)
(service php-fpm-service-type)
(service nginx-service-type
(nginx-server-configuration
(server-name '("example.com"))
(root "/srv/http/")
(locations
(list (nginx-php-location)))
(https-port #f)
(ssl-certificate #f)
(ssl-certificate-key #f)))
%base-services))
@end example
@node Certificate Services
@subsubsection Certificate Services
