To check the status of postgresql service, Run the below command. postgresql-setup initdbĪfter initializing the database, Start the postgresql service using the below command. We need to initialize the database using the below command. sudo yum install postgresql-server postgresql-contrib Update the centos default software repository, yum updateĪnd install the postgresql packages using the below command. Loaded: loaded (/usr/lib/systemd/system/postgresql-13.Login to the Server, make sure you have sudo or root privileges to install packages. ![]() Verify the status of PostgreSQL database service to ensure that it is started successfully. # systemctl enable -now postgresql-13Ĭreated symlink /etc/systemd/system//rvice → /usr/lib/systemd/system/rvice. # /usr/pgsql-13/bin/postgresql-13-setup initdbĮnable and start PostgreSQL database service. Initialize the PostgreSQL database server. Now, you can install your preferred version of PostgreSQL database by using dnf command.Īlthough, PostgreSQL 14 has been released, but we are using PostgreSQL 13 due to the stability and support by PostGIS extension. # dnf install -y ĭisable the built-in PostgreSQL module in standard yum repository. Install PostgreSQL yum repository by executing following dnf command. This yum repository provides all the required packages to install PostgreSQL and PostGIS on your Linux distribution. But the preferred way is to install is by adding PostgreSQL official yum repository in your Linux server. You can also install the PostgreSQL database from source. Therefore, you have to install PostgreSQL database before installing PostGIS extension. Install PostgreSQL Yum Repository on CentOS / RHEL 8: REDHAT_SUPPORT_PRODUCT="Red Hat Enterprise Linux" REDHAT_BUGZILLA_PRODUCT="Red Hat Enterprise Linux 8" PRETTY_NAME="Red Hat Enterprise Linux 8.4 (Ootpa)"ĬPE_NAME="cpe:/o:redhat:enterprise_linux:8.4:GA" # rebootĪfter reboot, verify the version of your Linux Kernel and operating system. If the above command updates your Linux Kernel, then you should reboot your operating system with the new Linux Kernel. You can update software packages in your Linux operating system, by executing following command. Operating System - Red Hat Enterprise Linux 8.4īy using a SSH client, connect with as root user.We are using a minimal Red Hat Enterprise Linux 8 virtual machine with following specifications. For raster data, PostGIS WKT Raster (now integrated into PostGIS 2.0+ and renamed PostGIS Raster).Index selectivity support, to provide high performance query plans for mixed spatial/non-spatial queries.R-tree-over-GiST (Generalized Search Tree) spatial indexes for high speed spatial querying.Spatial operators for determining geospatial set operations, like union, difference, symmetric difference and buffers (provided by GEOS).Spatial operators for determining geospatial measurements like area, distance, length and perimeter.Spatial predicates for determining the interactions of geometries using the 3x3 DE-9IM (provided by the GEOS software library).Geometry types for Points, LineStrings, Polygons, MultiPoints, MultiLineStrings, MultiPolygons and Geometr圜ollections.Some of the famous features of PostGIS are: Recommended Book: PostGIS in Action, Third Edition by Leo S. Using light-weight geometries helps servers increase the amount of data migrated up from physical disk storage into RAM, improving query performance substantially. The PostGIS implementation is based on "light-weight" geometries and indexes optimized to reduce disk and memory footprint. ![]() Technically PostGIS was implemented as a PostgreSQL external extension. PostGIS follows the Simple Features for SQL specification from the Open Geospatial Consortium (OGC). PostGIS is an open source software program that adds support for geographic objects to the PostgreSQL object-relational database. Configure PostGIS extension for PostgreSQL.Install PostGIS Extension on CentOS / RHEL 8.Install PostgreSQL Yum Repository on CentOS / RHEL 8.Here, you will learn how to install PostGIS on CentOS / RHEL 8 or similar Linux distros. PostGIS is an extension for PostgreSQL database for adding support of Geospatial data. ![]()
