Light Fast Map Server

This is a configuration of Map Server WMS as fast-cgi module of Lighttpd. Here I am compiling all main software packages from the source code on a 64bit Linux operating
system to get maximum performance. I hope my readers having experience in installing & configuring software packages under Linux platform. I prefer a CentOS 5.4 ×86_64 Linux
minimal server installation, because it is quite stable for me so far.
Prerequisites
Make sure that you have installed the following packages, normally it comes with the operating system installation.

cc gcc-c++ python python-devel krb5-devel readline-devel make swig pcre-devel libpng libpng-devel
bzip2-devel fontconfig fontconfig-devel libxml2-devel penssl-devel 
curl-devel giflib-devel zlib-devel gettext libjpeg-devel libtiff-devel

If any of the package is not installed, install it by using YUM. For example if gcc is missing

yum install gcc-c++

Ok, let’s start with the main software packages installation for Map Server,
PostgresSQL
The world’s most advanced open source database server.I prefer PostgresSQL server to store the vector map data, for fast searching and rendering of WMS map tiles.
Download the sourcehttp://www.postgresql.org/
Installation & Configuration.

tar -xzf postgresql-8.4.2.tar.gz
cd postgresql-8.4.2/
./configure —prefix=/usr/local/pgsql —with-perl —with-python —with-krb5
make
make install
adduser postgres
mkdir /var/lib/pgsql
chown -R postgres /var/lib/pgsql
su postgres
/usr/local/pgsql/bin/initdb -D /var/lib/pgsql/data
/usr/local/pgsql/bin/postgres -i -h localhost -p 5432 -D /var/lib/pgsql/data &

Now your PostgreSQL server is up and running. If you need an init.d startup script, download it from here http://nishad.us/docs/softwares/postgresql.txt
FastCGI
FastCGI is a protocol for interfacing interactive programs with a web server. This is a variation on the earlier Common Gateway Interface (CGI). Unlike CGI, It cannot
duplicates the universality of CGI overnight. It runs applications in processes isolated from the core Web server, which provides greater security than APIs. Not only does FastCGI restore the strengths of CGI, it also adds two new benefits like Distributed computing and Multiple extensible roles.

GD

GD is used for dynamic creation of images like PNG, JPEG and GIF images, among other formats. GD is commonly used to generate charts, graphics, thumbnails, and most anything
else, on the fly.

PostGIS PostGIS PostGIS adds support for geographic objects to the PostgreSQL object-relational database. In effect, PostGIS “spatially enables” the PostgreSQL server, allowing it to
be used as a backend spatial database for geographic information systems (GIS).

Download the source[ http://postgis.refractions.net/]

Installation & Configuration

tar -xzf softwares/postgis-1.5.1.tar.gz
cd postgis-1.5.1/

make
make install

You have successfully configured postGIS with PostgreSQL and Geos, compiled the source and installed the binaries. Now you create a PostgreSQL database and spatially enables
it by importing the PostGIS sql functions.

createdb -U postgres testgis
createlang -U postgres plpgsql testgis
psql -U postgres testgis < postgis/postgis.sql
psql -U postgres testgis < spatial_ref_sys.sql

GDAL

GDAL (Geospatial Data Abstraction Library) is a library for reading and writing raster geospatial data formats. As a library, it presents a single abstract data model to the
calling application for all supported formats. It may also be built with a variety of useful command-line utilities for data translation and processing.

Download the source http://www.gdal.org/

Installation & Configuration

—with-gif=/usr/ —with-pg=/usr/local/pgsql/bin/pg_config —with-geos=/usr/local/ —with-python
make
make install

You have successfully compiled Gdal with png,tiff,jpeg,gif,PostgreSQL and python. Now your Gdal library is available to build the Map Server.

Map Server

MapServer is geographic data rendering engine, providing spatial context where needed. It allows you to create geographic image maps that can direct users to content. It was
originally developed by the University of Minnesota (UMN) ForNet? project in cooperation with NASA. The main features are,

  • Advanced cartographic output
  • Scale dependent feature drawing and application execution
  • Feature labeling including label collision mediation
  • Fully customizable, template driven output
  • True Type fonts
  • Map element automation (scalebar, reference map, and legend)
  • Thematic mapping using logical- or regular expression-based classes
  • Support for popular scripting and development environments, ie PHP, Python, Perl, Ruby, Java.
  • Cross-platform support
  • Support of numerous Open Geospatial Consortium (OGC) standards, ie WMS,WFS, WMC, WCS, Filter Encoding, SLD, GML, SOS, OM
  • A multitude of raster and vector data formats, ie TIFF/GeoTIFF, EPPL7, ESRI shapfiles, PostGIS, ESRI ArcSDE, Oracle Spatial, MySQL
  • On-the-fly map projection with 1000s of projections through the Proj.4 library.

PHP & Map server FastCGI configuration with Lighttpd. Edit Lighttpd.conf,

vi /etc/lighttpd/lighttpd.conf

and insert below configuration under the fastcgi section.

fastcgi.server = ( “.php” =>
( “localhost” =>
(
“socket” => “/tmp/php-fastcgi.socket”,
“bin-path” => “/usr/local/php5/bin/php-cgi”
)
),
“/map” =>
( “localhost” =>
(
“socket” => “/tmp/mapserver-fastcgi.socket”,
“bin-path” => “/var/www/cgi-bin/mapserv”,
“max-procs” => 1,
“check-local” => “disable”
)
)
)

Restart your Lighttpd server.

/etc/init.d/lighttpd restart

Your Light Speed FastCGI Map Server Web Map Service(WMS) is up and running now. :) Try it from the URL http://localhost/maps?map=yourmapfile.map
