# Script to install PostgreSQL and PostGIS on a fresh Amazon Linux instance

# Installing from source:
# - GEOS 
# GEOS 3.10+ requires CMake 3+, not readily available on Amazon Linux 2.
GEOSVER=3.9.2
GEOSURL=http://download.osgeo.org/geos/geos-${GEOSVER}.tar.bz2

# - PROJ (GDAL requires 6+; 6.2.1 is the last to use SQLite 3.7; 6.2 had build issues, so 6.1.1)
PROJVER=6.1.1
PROJURL=https://download.osgeo.org/proj/proj-${PROJVER}.tar.gz

# - GDAL 
GDALVER=3.4.3
GDALURL=https://github.com/OSGeo/gdal/releases/download/v${GDALVER}/gdal-${GDALVER}.tar.gz

# - PostGIS 
POSTGISVER=3.2.1

Your system is now running PostgreSQL with PostGIS. 
You should now run "aws configure" to set up the AWS CLI.   
Afterwards, you should stop this instance and create an AMI.

Updated this script to use PostgreSQL 13 and PostGIS 3.2.

Pushed another update this morning to address a typo and missing requirement. You should be able to run this script on a fresh Amazon Linux install and end up with PostgreSQL 13 with PostGIS 3.2.

Please comment if you have any issues. If you find & resolve an issue, please open a PR!

Hope this helps!

Also, if you require common extensions (e.g. uuid, fuzzystrmatch) make sure you sudo yum install postgresql-contrib.

incase anyone stumbles across this and you tried installing the latest individually.
i.e postgresql14 with paths like /usr/pgsql-14/
this wont work for you:

sudo ln -s /usr/local/lib/libgeos_c.so.1 /usr/lib64/pgsql/libgeos_c.so.1
sudo sh -c 'echo /usr/local/lib > /etc/ld.so.conf.d/postgresql.conf'
sudo sh -c 'echo /usr/lib64/pgsql >> /etc/ld.so.conf.d/postgresql.conf'
sudo ldconfig -v

use this instead:

sudo su
echo /usr/local/lib >> /etc/ld.so.conf
exit
sudo ldconfig

I got a conflict between postgresql-devel and libpq-devel when running a fresh install. Changing line 29 to the following fixed it.

sudo yum install -y postgresql-server postgresql-server-devel

Thank you, this has been incorporated.

Note to others - while this includes the PostGIS extension, it does not include other common (e.g. fuzzystrmatch) extensions. To add them, simply run: sudo yum install -y postgresql-contrib
