System Requirements

Hardware and software specifications required to deploy and operate GeoServer effectively across different production scales.

Server Specifications

GeoServer is a resource-intensive application, particularly when handling large raster datasets or complex vector aggregations. We recommend provisioning resources based on your expected concurrent load and dataset size.

Database & Data Stores

GeoServer itself does not store spatial data; it serves data from external stores. Your database performance directly impacts map rendering speeds.

PostgreSQL / PostGIS (Recommended)

• PostgreSQL version 13 or higher.
• PostGIS extension version 3.1+ (3.3+ for advanced raster ops).
• Proper indexing (GIST) on geometry columns.
• Enable postgis.backend optimizations in postgresql.conf.

# Check PostGIS Version
SELECT PostGIS_Version();

# Recommended shared_buffers setting for 16GB RAM server
shared_buffers = 4GB
work_mem = 128MB

Supported Data Sources

• PostgreSQL / PostGIS
• Oracle Spatial
• MySQL / MariaDB (with limitations)
• GeoTIFF / COG (Cloud Optimized GeoTIFF)
• Shapefile (Read-only, not recommended for production)
• WFS/WMS Remote Sources

Client / Browser Requirements

For the Web Admin Interface and modern map clients, the following browsers are supported:

Verification Commands

Before deploying, verify your environment meets the baseline criteria:

#!/bin/bash
# Environment Check Script

echo "=== Java Version ==="
java -version 2>&1 | head -n 1

echo "=== Disk Space ==="
df -h / | tail -n 1

echo "=== Memory ==="
free -h | grep Mem

echo "=== Kernel ==="
uname -r

echo "=== PostGIS ==="
psql -d gis_db -c "SELECT PostGIS_Version();"
