Enterprise Linux (EL) and derivatives (that is, Red Hat Enterprise Linux, CentOS and Scientific Linux) is a popular and robust platform for servers and computing-heavy workstations, and is therefore a good fit for GIS specific requirements.

The goal of the Enterprise Linux GIS (ELGIS) effort is to ensure that the latest stable versions of the main free GIS software run on the Enterprise Linux platform.

The mailing list el@lists.osgeo.org is used for communication (archive). Subscribers to the mailing-list are basically the community around ELGIS and are meant to be consulted for important choices (like which packages to support).

Open issues are listed here. Please have a look at this list before asking the mailing-list for support on a particular problem.

There is also a low-traffic Twitter account, mainly used for announcements.

Useful RPM repositories for GIS software

  • ELGIS repositories try to ensure that the latest stable versions of the major FLOSS GIS software are available for Enterprise Linux. They maintain versions of packages which cannot be maintained in EPEL, or that EPEL does not want to keep at the latest stable version. This is where our packaging effort currently takes place, and can be seen as a kind of backport repository.

ELGIS requires EPEL to be configured as an additional repository.

  • EPEL is an official Fedora project which repackages many Fedora packages which are not part of the standard EL distribution. It contains quite a few GIS packages and base libraries. Note that one of the rules of the packages maintained in EPEL is that they should never require to change the base EL distribution. Moreover they rather follow Enterprise Linux policy of not using the latest version of the software but rather to stick with a given version in order to ensure stability and predictability.
  • PGRPMS provides the latest versions of PostgreSQL (e.g. the 9.x versions not available in Enterprise Linux) as well as an up to date PostGIS. This is an option if you just want to run PostGIS and needs recent PostgreSQL features as well.

PGRPMS is NOT compatible with ELGIS, don't enable both or you will break your environment.

RHEL / CentOS / Scientific Linux 6

Note (2012-12-01): the version of geos in EPEL is newer than the one in ELGIS stable, which causes problems, notably with GRASS. Disable geos from the EPEL repo file, or use ELGIS Testing. This will be solved soon when ELGIS Testing is moved to Stable. (see http://lists.osgeo.org/pipermail/el/2012-November/001060.html)

How to enable the ELGIS6 repository

sudo rpm -Uvh http://elgis.argeo.org/repos/6/elgis-release-6-6_0.noarch.rpm

As of November 28th 2011, ELGIS Stable contains only the 64 bits binaries. For 32 bits, you will have to enable ELGIS Testing.

Packages matrix

If you want to contribute packages to the ELGIS repo

  • Especially for new packages, please try to build them in mock first (the one from CentOS, not from EPEL!), so that all build dependencies are in the spec file. You can find some mock config files here. Don't hesitate to ask on the mailing-list if you need support for your first mock builds: this is much easier than it seems, and very clean

Then send you spec file to the mailing-list or give download access to an SRPM.

Note about Fedora, ELGIS and EPEL

  • in general, Fedora packages are the upstream source for Enterprise Linux packages (be they in the EPEL or ELGIS repos)
  • ELGIS depends on EPEL, complements it and sometimes overrides it
  • ELGIS mission is to provide the latest stable version of the main Free GIS packages, whereas EPEL has a policy of keeping versions stable across an upstream release lifecycle
  • packages that cannot be in EPEL (typically because they require to update the base platform) can be maintained in the ELGIS Plus repo (it is expected that there will be very few of them at the beginning of the EL6 life cycle)
  • our goal is not primarily to provide packages but also to serve as a knowledge base for FLOSS GIS software usage on Enterprise Linux. Therefore EL specific questions related to GIS packages from EPEL are welcome on the ELGIS list, and information about them will be documented in the other resources provided by the OSGeo foundation (wiki, trac, etc.)

How To

How to hack and locally build the ELGIS packages

ELGIS6 packages are now maintained in Git repositories which are forks from Fedora/EPEL Git repositories: http://elgis.argeo.org/gitweb/

In order to build a package (here: geos):

  • Use the mock file below
  • Clone the repository you are interested in to a local directory (here: ~/dev/git/elgis.argeo.org)
git clone -b elgis6 git://elgis.argeo.org/geos.git
  • Download the sources to a local directory (here: ~/dev/git/elgis.argeo.org/sources)
  • Run mock:
mock --scm-enable -r elgis-6-testing-x86_64 --scm-option package=geos -v

How to hack and locally build the ELGIS packages (old)

For the time being, the ELGIS packages (that is, those not maintained by EPEL) are versioned by and distributed through argeo.org.

You can see the currently versioned packages here:

Note: simply accept the self-signed certificate

You can checkout all the packages: 

svn co https://projects.argeo.org/elgis/svn/factory/trunk/rpmbuild rpms

Or one by one, for example: 

svn co https://projects.argeo.org/elgis/svn/factory/trunk/rpmbuild/elgis/gdal gdal

Each package directory follows the directory structure expected by rpmbuild (see how to set an rpmbuild environment).

We version only the spec files (under <package name>/SPECS/<package name>.spec) and the patches or some light sources (under <package name>/SOURCES). The source packages of the underlying libraries needs to be downloaded in the SOURCES directory.

Please send patches to the spec files to the el@lists.osgeo.org mailing-list.

In order to actually build, you can then configure %_topdir in your ~/.rpmmacros file to point to where you checked out a package, for example: 

%_topdir %(echo $HOME)/dev/rpmbuild
%rhel 5
%packager Mathieu Baudier <mbaudier@argeo.org>
%dist .el5.elgis

A more persistent alternative is to have the two following files in each package directory:

  • <package directory>/rpmrc
include: /usr/lib/rpm/rpmrc
macrofiles: /usr/lib/rpm/macros:/usr/lib/rpm/ia32e-linux/macros:/usr/lib/rpm/redhat/macros:/etc/rpm/macros.*:/etc/rpm/macros:/etc/rpm/ia32e-linux/macros:~/.rpmmacros:<package directory>/rpmmacros

(note the ':<package directory>/rpmmacros' appended at the end of the macrofiles line)

  • <package directory>/rpmmacros
%_topdir <package directory>
%rhel 5
%packager Mathieu Baudier <mbaudier@argeo.org>
%dist .el5.argeo

And then call rpmbuild as follow 

cd <package directory>
rpmbuild --rcfile=rpmrc -ba SPECS/<package name>.spec

These two files are registered in svn:ignore and can typically be automatically generated by scripts or a build framework.

How to deploy GeoServer 2.1 (standard packages not using the ELGIS repository)

This how-to goes through the various steps required to have GeoServer 2.1 running as a Java web application inside the standard Tomcat 5 container. It has been tested with CentOS 5.6 x86_64.

Basic install (with base OpenJdk)

  • Install the required packages
sudo yum install java-1.6.0-openjdk-devel tomcat5
  • (optional) Install tomcat-native frop EPEL
sudo yum install tomcat-native
  • Download GeoServer
cd ~/Downloads
wget http://sourceforge.net/projects/geoserver/files/GeoServer/2.1.1/geoserver-2.1.1-war.zip/download?use_mirror=ignum
  • (optional) Backup previous deployment
# Stop Tomcat
sudo /sbin/service tomcat5 stop
# Backup previous data dir
sudo tar -czf /srv/backups/geoserver/geoserver-data-110624.tar.gz /var/lib/geoserver/data
# Backup up previous install
sudo mv /var/lib/tomcat5/webapps/geoserver* /srv/backups/geoserver/2.0.2/
  • Unpack to Tomcat webapps
cd /var/lib/tomcat5/webapps/
sudo unzip ~/Downloads/geoserver-2.1.1-war.zip geoserver.war
  • (new installs only) Create a separate data directory
sudo mkdir -p /var/lib/geoserver
cd /var/lib/geoserver
sudo jar -xvf /var/lib/tomcat5/webapps/geoserver.war data
sudo chown -R tomcat.tomcat /var/lib/geoserver
  • Update /etc/tomcat/tomcat5.conf to add the recommended Java settings and to point to the data directory. You can increase/decrease the maximum memory allocated to Java with the -Xmx flag (-Xms is the initial allocation):
# Geoserver recommended
# http://docs.geoserver.org/stable/en/user/production/container.html
JAVA_OPTS="-showversion -server -Xmx512m -Xms64m -XX:SoftRefLRUPolicyMSPerMB=36000 -XX:MaxPermSize=128m -XX:+UseParallelGC"
JAVA_OPTS="$JAVA_OPTS -DGEOSERVER_DATA_DIR=/var/lib/geoserver/data"
  • (optional ?) Update web.xml to take the data directory (seems to work with only the system property specified)
...
    <context-param>
       <param-name>GEOSERVER_DATA_DIR</param-name>
        <param-value>/var/lib/geoserver/data</param-value>
    </context-param> 
...
  • Add an AJP proxy in the Apache configuration (e.g. in /etc/httpd/conf.d/geoserver.conf)
<Location /geoserver/>
	ProxyPass  ajp://localhost:8009/geoserver/
	# Uncomment to forbid non ssl access
	#RequireSSL
</Location>
  • (optional) If using SELinux, allow the proxying by setting the appropriate boolean
setsebool -P httpd_can_network_connect=1
  • Start Tomcat
sudo /sbin/service tomcat5 start
  • (optional) You can tail Tomcat logs to make sure that it is starting properly
tail -500f /var/log/tomcat5/catalina.out
  • Restart Apache
sudo /sbin/service httpd restart

Update GeoServer to a new minor release

cd /var/lib/tomcat5/webapps
sudo unzip ~/Downloads/geoserver-2.1.3-war.zip geoserver.war
sudo mv geoserver geoserver-2.1.1
sudo -u tomcat mkdir geoserver
cd geoserver
sudo -u tomcat jar -xvf ../geoserver.war
sudo -u tomcat cp -v ../geoserver-2.1.1/WEB-INF/{applicationSecurityContext.xml,web.xml} WEB-INF/
# (optional) Spring LDAP
sudo -u tomcat cp -v ../geoserver-2.1.1/WEB-INF/lib/spring-ldap-1.3.1.RELEASE-all.jar WEB-INF/lib
sudo /sbin/service tomcat5 start

There may be some stacktraces when restarting: "IOException while loading persisted sessions: java.io.InvalidClassException". Don't worry about them, just refresh your browser windows.

With Sun/Oracle JRE and JAI native (recommended by GeoServer)

GeoServer documentation recommends to use a Sun/Oracle JRE with the JAI and JAI-ImageIO native extensions. There was an obvious performaince gain inthe tile generation by doing so

  • Download in install Sun/Oracle JDK in /opt (a JRE should be enough)
  • Hack the /usr/bin/dtomcat5 script to add an explicit reference to Sun/Oracle JDK at the beginning (did not find any better way neither through /etc/tomcat5/tomcat5.conf nor /etc/init.d/tomcat5 nor the alternatives system, ideas welcome...)
...
JAVA_HOME=/opt/jdk1.6.0_21
...
  • Go into the Sun JDK directory:
cd /opt/jdk1.6.0_21

sudo sh ~/Downloads/jai-1_1_3-lib-linux-amd64-jdk.bin

sed s/+215/-n+215/ jai_imageio-1_1-lib-linux-amd64-jdk.bin > jai_imageio-1_1-lib-linux-amd64-jdk-fixed.bin
  • Install JAI-ImageIO
sudo sh ~/Downloads/jai_imageio-1_1-lib-linux-amd64-jdk-fixed.bin
  • Restart Tomcat
sudo /sbin/service tomcat5 restart
  • Visit your GeoServer status page in order to make sure that native JAI is taken into account

LDAP Authentication

This will allow you to have you user referential in LDAP (tested with base CentOS 5 openldap-servers). Your users need to be inetOrgPerson under ou=People,dc=my_org,dc=org Your GeoServer administrators need to belong to the cn=administrator,ou=Roles,dc=my_org,dc=org role: 

dn: cn=administrator,ou=Roles,dc=my_org,dc=org
objectClass: top
objectClass: groupOfNames
cn: administrator
member: uid=mbaudier,ou=People,dc=my_org,dc=org

Other roles can be defined similarly under ou=Roles,dc=argeo,dc=org, and should be added mnaually when defining rules in GeoServer. You can of course adapt the following configuration with your specific LDAP settings.

Caveats:

  • the list of users won't be properly displayed in GeoServer.
  • as usual with autentication via HTTP make sure that users are using SSL (https://) when they authenticate, otherwise their credentials will be sent in clear. If you want to mix public with private data and stay compatible with client which don't support HTTPS, this is not necessarily easy.

Procedure:

  • Download spring-ldap and copy it to the WEB-INF/lib directory of GeoServer:
cd /var/lib/tomcat5/webapps/geoserver/WEB-INF/lib
sudo wget http://search.maven.org/remotecontent?filepath=org/springframework/ldap/spring-ldap/1.3.1.RELEASE/spring-ldap-1.3.1.RELEASE-all.jar -O spring-ldap-1.3.1.RELEASE-all.jar
  • Extract applicationContextSecurity.xml from the main-jar (in /var/lib/tomcat5/webapps/geoserver/WEB-INF/lib/)
  • Copy it to /var/lib/tomcat5/webapps/geoserver/WEB-INF/
  • Add the following at the beginning of the applicationContextSecurity.xml file (after the <beans> tag)
 <beans>
	<!-- CUSTOM : LDAP config -->
	<bean id="contextSource" class="org.springframework.security.ldap.DefaultSpringSecurityContextSource">

	<!-- END OF CUSTOM LDAP CONFIGURATION -->

  <bean id="filterChainProxy"
    class="org.springframework.security.util.FilterChainProxy">

    ...
  • Modify the following section
 ...
  <bean id="authenticationManager"
    class="org.springframework.security.providers.ProviderManager">
    <property name="providers">
      <list>
		<ref local="ldapAuthenticationProvider" />
<!--         <ref local="daoAuthenticationProvider" /> -->
 ...
  • Modify /var/lib/tomcat5/webapps/geoserver/WEB-INF/web.xml to use WEB-INF/applicationSecurityContext.xml instead of classpath*:/applicationSecurityContext.xml
 ...
     <context-param>
         <param-name>contextConfigLocation</param-name>
         <param-value>classpath*:/applicationContext.xml WEB-INF/applicationSecurityContext.xml</param-value>
     </context-param>
 ...
  • Restart Tomcat
sudo /sbin/service tomcat5 restart
