$ sudo yum update
Install postgresql, postgresql-devel, and postgresql-libs, and configure data directory and start the service (as the postgres user).
$ sudo yum install postgresql postgresql-server postgresql-devel
$ sudo mkdir /usr/local/pgsql/
$ sudo mkdir /usr/local/pgsql/data
$ sudo chown postgres /usr/local/pgsql/data
$ sudo su postgres
Install PostGIS. First we install some build tools and the GEOS and PROJ libraries. Then we install PostGIS. After all of them are installed, we update our libraries, so the server knows where to find them. Finally we create a template database for PostGIS.
$ mkdir postgis
$ cd postgis
$ sudo yum install gcc make gcc-c++ libtool libxml2-devel
$ wget http://download.osgeo.org/geos/geos-3.6.2.tar.bz2
$ tar xjvf geos-3.6.2.tar.bz2
$ cd geos-3.6.2
$ ./configure
$ make
$ sudo make install
$ wget http://download.osgeo.org/proj/proj-4.9.3.tar.gz
$ wget http://download.osgeo.org/proj/proj-datumgrid-1.6.zip
$ tar zxvf proj-4.9.3.tar.gz
$ cd proj-4.9.3/nad/
$ unzip ../../proj-datumgrid-1.6.zip
$ cd ..
$ ./configure
$ make
$ sudo make install
postgis-2.4.1 was throwing an error, but I cannot recall what. I reverted to a previous version. I specify the --without-raster tag here, because I do not have or need GDAL on this instance, elsewise the configure process will fail.
$ wget http://download.osgeo.org/postgis/source/postgis-2.3.1.tar.gz
$ tar zxvf postgis-2.3.1.tar.gz
$ cd postgis-2.3.1
$ ./configure --with-geosconfig=/usr/local/bin/geos-config --without-raster
$ make
$ sudo make install
$ sudo su
$ sudo ldconfig
$ createdb -U postgres template_postgis
$ psql -U postgres -d template_postgis < /usr/share/pgsql92/contrib/postgis-2.3.1/postgis.sql
$ psql -U postgres -d template_postgis < /usr/share/pgsql92/contrib/postgis-2.3/postgis.sql
$ psql -U postgres -d template_postgis < /usr/share/pgsql92/contrib/postgis-2.3/spatial_ref_sys.sql
GeoServer 2.12.0 + require Java 8, but current aws Linux boxes still come with Java 7, so we need to update to the latest version.
$ sudo yum install -y java-1.8.0-openjdk.x86_64
$ java -version
$ sudo /usr/sbin/alternatives --set java /usr/lib/jvm/jre-1.8.0-openjdk.x86_64/bin/java
$ sudo /usr/sbin/alternatives --set javac /usr/lib/jvm/jre-1.8.0-openjdk.x86_64/bin/javac
$ sudo yum remove java-1.7
$ java -version
Install Apache HTTP Server and Apache Tomcat is very simple. I used tomcat8, though I would have used tomcat9 if I were to do it again.
$ sudo yum install httpd httpd-devel tomcat8
Download the GeoServer web archive and move it to Tomcat’s webapps directory.
$ cd
$ mkdir geoserver
$ cd geoserver/
$ wget http://sourceforge.net/projects/geoserver/files/GeoServer/2.12.0/geoserver-2.12.0-war.zip
$ unzip geoserver-2.12.0-war.zip
$ sudo chown tomcat:tomcat geoserver.war
$ sudo mv geoserver.war /var/lib/tomcat8/webapps/
$ cd ..
$ mkdir modjk
$ cd modjk/
$ wget https://www.apache.org/dist/tomcat/tomcat-connectors/jk/tomcat-connectors-1.2.42-src.tar.gz
$ tar xzf tomcat-connectors-1.2.42-src.tar.gz
$ cd tomcat-connectors-1.2.42-src/native/
$ ./configure --with-apxs=/usr/sbin/apxs
$ make
$ sudo make install
$ sudo vim /etc/httpd/conf/httpd.conf
In Vim, add the following to the bottom of the file:
# Update this path to match your modules location
LoadModule jk_module /usr/lib64/httpd/modules/mod_jk.so
# Where to find workers.properties
# Update this path to match your conf directory location (put workers.properties next to httpd.conf)
JkWorkersFile /etc/httpd/conf/workers.properties
# Where to put jk shared memory
# Update this path to match your local state directory or logs directory
JkShmFile /var/log/httpd/mod_jk.shm
# Where to put jk logs
# Update this path to match your logs directory location (put mod_jk.log next to access_log)
JkLogFile /var/log/httpd/mod_jk.log
# Set the jk log level [debug/error/info]
JkLogLevel info
# Select the timestamp log format
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
# Send everything for context /geoserver and /geoserver/* to worker named geoserver_worker (ajp13)
JkMount /geoserver/* geoserver_worker
JkMount /geoserver geoserver_worker
$ sudo vim /etc/httpd/conf/workers.properties
In Vim, add following code:
# Define the list of workers that will be used
worker.list=geoserver_worker
# Define geoserver_worker
worker.geoserver_worker.port=8009
worker.geoserver_worker.host=localhost
worker.geoserver_worker.type=ajp13
At this time, everything is installed and configured, and we are ready to start Apache HTTP Server and Apache Tomcat.
$ sudo /sbin/service httpd start
$ sudo /sbin/service tomcat8 start
This server setup is adapted from this most helpful post. The main differences are version upgrades and the quirks that come with them.
