GDAL

Simple functionality can be got from the Debian package: 

apt-get install gdal-bin

Advanced functionality requires the latest version (install into /usr/local): 

apt-get install -y g++ libproj-dev
cd /tmp
wget http://download.osgeo.org/gdal/1.11.4/gdal-1.11.4.tar.gz
tar zxvf gdal-1.11.4.tar.gz
cd gdal-1.11.4
./configure --with-python CPPFLAGS="-fPIC"
make
make install
cd ..
ldconfig

Python bindings (e.g. needed for Shapefile Layers and GADM importer) included in above version.

e.g. If you are serving GeoTIFFs larger than 2Gb, you should create an ​Image Pyramid: 

mkdir pyramid
~/gdal-1.11.2/swig/python/scripts/gdal_retile.py -v -s_srs EPSG:4326 -r bilinear -levels 4 -ps 2048 2048 -co "TILED=YES" -co "COMPRESS=JPEG" -targetDir pyramid mygeotiff.tif

PostGIS

​PostGIS adds Spatial storage to PostgreSQL (visit this page to configure PostgreSQL before returning here to continue with the GIS parts)

NB PostGIS in Debian Lenny or Squeeze is rather old - recommend using the version in Wheezy, ideally the upgraded from external packages (native version shown commented):

Wheezy users: 

apt-get install -y postgis
su postgres
createuser -s -P gis

createdb -O gis -E UTF8 gis -T template0
#psql -d gis -f /usr/share/postgresql/9.1/contrib/postgis-1.5/postgis.sql
#psql -d gis -f /usr/share/postgresql/9.1/contrib/postgis-1.5/spatial_ref_sys.sql
psql -d gis -f /usr/share/postgresql/9.3/extension/postgis--2.1.7.sql

Squeeze users: 

apt-get install -y postgresql-8.4-postgis
su postgres
createuser -s -P gis

createdb -O gis gis
createlang plpgsql -d gis
psql -d gis -f /usr/share/postgresql/8.4/contrib/postgis-1.5/postgis.sql
psql -d gis -f /usr/share/postgresql/8.4/contrib/postgis-1.5/spatial_ref_sys.sql

Ubuntu users (Lucid/PostgreSQL 8.4/Post-GIS 1.4) - the paths are slightly different 

psql -d gis -f /usr/share/postgresql/8.4/contrib/postgis.sql
psql -d gis -f /usr/share/postgresql/8.4/contrib/spatial_ref_sys.sql

Add Spherical Mercator projection (900913. See ​http://www.cadmaps.com/gisblog/?p=81 for 54004):

  • Not needed with PostGIS-1.5 :) 
    psql gis
INSERT into spatial_ref_sys (srid, auth_name, auth_srid, srtext, proj4text) values (900913 ,'EPSG',900913,'GEOGCS["WGS 84", DATUM["World Geodetic System 1984", SPHEROID["WGS 84", 6378137.0, 298.257223563,AUTHORITY["EPSG","7030"]], AUTHORITY["EPSG","6326"]],PRIMEM["Greenwich", 0.0, AUTHORITY["EPSG","8901"]], NIT["degree",0.017453292519943295], AXIS["Longitude", EAST], AXIS["Latitude", NORTH],AUTHORITY["EPSG","4326"]], PROJECTION["Mercator_1SP"],PARAMETER["semi_minor", 6378137.0], PARAMETER["latitude_of_origin",0.0], PARAMETER["central_meridian", 0.0], PARAMETER["scale_factor",1.0], PARAMETER["false_easting", 0.0], PARAMETER["false_northing", 0.0],UNIT["m", 1.0], AXIS["x", EAST], AXIS["y", NORTH],AUTHORITY["EPSG","900913"]] |','+proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0 +units=m +nadgrids=@null +no_defs');

Using PostGIS in Sahana

Java

​Update: As of version 2.0, a Java Runtime Environment (JRE) is sufficient to run GeoServer. GeoServer no longer requires a Java Development Kit (JDK). Also note, OpenJDK does not work optimally with GeoServer. As of version 2.9, Jave 8 is required.

Install the JAI extensions (improves performance for GeoServer WMS), the downloads available are listed ​here

64-bit: 

cd /usr/lib/jvm/java-sun
wget https://download.java.net/media/jai/builds/release/1_1_3/jai-1_1_3-lib-linux-amd64-jdk.bin
wget https://download.java.net/media/jai-imageio/builds/release/1.1/jai_imageio-1_1-lib-linux-amd64-jdk.bin
sh jai-1_1_3-lib-linux-amd64-jdk.bin
# accept license
export _POSIX2_VERSION=199209
sh jai_imageio-1_1-lib-linux-amd64-jdk.bin
# accept license
rm jai-1_1_3-lib-linux-amd64-jdk.bin
rm jai_imageio-1_1-lib-linux-amd64-jdk.bin

If you installed JRE (sudo sh on Ubuntu) 

cd /usr/lib/jvm/java-sun/jre
wget https://download.java.net/media/jai/builds/release/1_1_3/jai-1_1_3-lib-linux-amd64-jre.bin
sh jai-1_1_3-lib-linux-amd64-jre.bin 
#accept licence and replace [yes]
rm jai-1_1_3-lib-linux-amd64-jre.bin

32-bit: 

cd /usr/lib/jvm/java-sun
wget https://download.java.net/media/jai/builds/release/1_1_3/jai-1_1_3-lib-linux-i586-jdk.bin
wget https://download.java.net/media/jai-imageio/builds/release/1.1/jai_imageio-1_1-lib-linux-i586-jdk.bin

Apache Tomcat

​Tomcat is the recommended way to deploy Java applications. As of GeoServer 2.9, Tomcat 7.0.65 or later is required. We suggest using Tomcat 8.0.x: 

apt-get install -y tomcat8 libtcnative-1

# http://docs.geoserver.org/latest/en/user/production/container.html#optimize-your-jvm
# Select appropriate value based on your available RAM
vim /etc/default/tomcat8
JAVA_HOME=/usr/lib/jvm/java-8-oracle
JAVA_OPTS="-Djava.awt.headless=true -Xmx256m -Xms48m -XX:MaxPermSize=128m -XX:SoftRefLRUPolicyMSPerMB=36000 -XX:+UseConcMarkSweepGC"
JAVA_OPTS="-Djava.awt.headless=true -Xmx2g -Xms64m -XX:MaxPermSize=128m -XX:SoftRefLRUPolicyMSPerMB=36000 -XX:+UseConcMarkSweepGC"

# Should be set already:

# Modify logging
vim /etc/tomcat8/server.xml
<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               ...
               ...
               rotatable="false" />

vim /etc/logrotate.d/tomcat8
/var/log/tomcat8/catalina.out /var/log/tomcat8/localhost_access_log..txt {
  copytruncate
  daily
  rotate 7
  compress
  missingok
  create 640 tomcat8 adm
}

/etc/init.d/tomcat8 restart
  • Ubuntu 10.x: 
    sudo apt-get install unzip lynx tomcat6 tomcat6-admin libapache2-mod-jk
vim /etc/libapache2-mod-jk/workers.properties
workers.java_home=/usr/lib/jvm/java-6-sun

/etc/init.d/tomcat6 restart
# should see stopping [OK] and starting [OK]

# change some permissions
cd /var/lib/tomcat6/
sudo chown -R tomcat6:tomcat6 logs work
sudo chown tomcat6:tomcat6 /usr/share/tomcat6

# check/change service port - default 8080
/etc/tomcat6/server.xml

Enable access to GeoServer on Port 80 (assuming not using Cherokee): 

# if using multiple Tomcats behind a single apache load-balancer
apt-get install apache2-mpm-worker
a2enmod proxy_ajp
a2dissite default

vim /etc/tomcat7/server.xml
# Uncomment these lines (& add the extra options)

# maxThreads here should match the Apache MPM's MaxClients

InstallationGuidelines/PhantomJS

MapFish

For Printing TMS layers, need to compile the Trunk version of the ​MapFish Print Module & then serve the resultant .war with ​Tomcat:

  1. Ensure that JAVA_HOME points to a JDK.
  2. Download & build source: 
    svn checkout http://www.mapfish.org/svn/mapfish/print/trunk/
cd trunk
./gradlew build
  3. Configure Tomcat 
    vim /etc/tomcat6/policy.d/04webapps.policy
permission java.io.FilePermission "/var/lib/tomcat6/webapps/print-servlet-1.2-SNAPSHOT/WEB-INF/classes/logging.properties", "read";

/etc/init.d/tomcat6 restart

vim /etc/apache2/sites-available/print


ln -s /etc/apache2/sites-available/print /etc/apache2/sites-enabled/print
/etc/init.d/apache2 restart
  4. Copy the WAR file to your %WEBAPPS% directory: 
    cp trunk/build/libs/print-servlet-1.2-SNAPSHOT.war /var/lib/tomcat6/webapps
  5. (re)Start Tomcat
  6. Configure the Map URL for Eden to:
  7. Configure %WEBAPPS%\print-servlet-1.2-SNAPSHOT\config.yaml: ​http://www.mapfish.org/doc/print/configuration.html

Printing can also be done within GeoServer:

The 2.0.x versiondidn't support TMS layers, like OpenStreetMap. @ToDo: Test this latest version. 

wget http://gridlock.opengeo.org/geoserver/2.1.x/community-latest/geoserver-2.1-SNAPSHOT-printing-plugin.zip
cd /var/lib/tomcat6/webapps/geoserver/WEB-INF/lib
unzip ~/geoserver-2.1-SNAPSHOT-printing-plugin.zip
/etc/init.d/tomcat6 restart
#wget http://geoserver.org/download/attachments/20938936/printing-data-2.0.x.zip
#cd /usr/local/geoserver-2.0.2/data_dir
#unzip ~/printing-data-2.0.x.zip
#/usr/local/geoserver/bin/shutdown.sh
#/usr/local/geoserver/bin/startup.sh &
  • Configure by editing /var/gis/geoserver_data_dir/printing/config.yaml according to ​Documentation

Print to Image

Proxy / Cache

A Proxy can cache remote servers &/or do Reprojection or Combination of Layers

If just wanting to cache the WMS served by GeoServer, then it's probably best to use the integrated GeoWebCache:

Alternatives:

NB This can reveal issues such as the max-width limitation on ArcGIS when converting 4326 to 900913:
