Perlbal::Manual::WebServer - Configuring Perlbal as a Web Server


=head2 VERSION

Perlbal 1.78.


=head2 DESCRIPTION

How to configure a Perlbal Web Server service.


=head2 READ ME FIRST

Please read L<Perlbal::Manual::Configuration> first for a better explanation on how to configure Perlbal. This document will make much more sense after reading that.


=head2 Configuring Perlbal as a Web Server

By default, perlbal looks for a configuration file at F</etc/perlbal/perlbal.conf>.

You can also point perlbal at a different configuration file with the B<-c> flag.

    $ perlbal -c /home/user/perlbal.conf


Here's a very simple example where we configure a simple web server that serves an index file under /tmp

    CREATE SERVICE perlbal_test
        SET role           = web_server
        SET listen         = 0.0.0.0:80
        SET docroot        = /tmp
    ENABLE perlbal_test

The first line creates a service called C<perlbal_test>. The last line enables that service.

The three parameters state - in order - that the service is a web server, that it listens on all addresses on port 80, and that its document root is C</tmp>.


=head2 Parameters

You can set parameters via commands of either forms:

    SET <service-name> <param> = <value>
    SET <param> = <value>


=over 8

=item B<dirindexing> = bool

Show directory indexes when an HTTP request is for a directory. Warning: this is not an async operation, so will slow down Perlbal on heavily loaded sites.

Default if false.


=item B<docroot> = directory/root

Directory root for web server.


=item B<enable_concatenate_get> = bool

Enable Perlbal's multiple-files-in-one-request mode, where a client have use a comma-separated list of files to return, always in text/plain.

Useful for web apps which have dozens/hundreds of tiny css/js files, and don't trust browsers/etc to do pipelining.

Decreases overall round-trip latency a bunch, but requires app to be modified to support it. See t/17-concat.t test for details.

Default is false.


=item B<enable_delete> = bool

Enable HTTP DELETE requests.

Default is false.


=item B<enable_put> = bool

Enable HTTP PUT requests.

Default is false.


=item B<index_files> = comma-separated list of filenames

Comma-separated list of filenames to load when a user visits a directory URL, listed in order of preference.

Default is index.html.


=item B<max_put_size> = size

The maximum content-length that will be accepted for a PUT request, if enable_put is on.

Default is 0, which means there is no limit.


=item B<min_put_directory> = int

If PUT requests are enabled, require this many levels of directories to already exist. If not, fail.

Default is 0.
