How to Install Presto 8.8 – Complete Step-by-Step Tutorial

Presto is a distributed SQL query engine designed for running fast queries on large datasets. This guide will walk you through installing Presto version 8.8 on a Linux system (Ubuntu/CentOS).

4.2 Configuración de JVM (jvm.config)

nano etc/jvm.config

Contenido mínimo para 8GB de RAM:

-server
-Xmx4G
-XX:+UseG1GC
-XX:G1HeapRegionSize=32M
-XX:+UseGCOverheadLimit
-XX:+ExplicitGCInvokesConcurrent
-XX:+HeapDumpOnOutOfMemoryError
-XX:OnOutOfMemoryError=kill -9 %p

Ajusta -Xmx según tu memoria disponible (máximo 70% de la RAM del sistema).

Step 4: Configure Presto

Create a configuration file for Presto:

sudo nano /opt/presto/etc/config.properties

Add the following configuration:

coordinator=true
node-scheduler.include-coordinator=true
discovery-server.enabled=true
discovery-server.port=8000
http-server.http.port=8080

Additional Configuration (Optional)

• Configure authentication and authorization
• Set up a catalog for your data source (e.g., Hive, MySQL)
• Optimize Presto performance for your specific use case

By following these steps, you should now have Presto 8.8 installed and running on your machine.

Step 7: Start Presto Server

cd /opt/presto
bin/launcher start

Check status:

bin/launcher status

View logs:

tail -f var/log/server.log

Troubleshooting Common Issues

| Problem | Solution | |---------|----------| | java.lang.UnsupportedClassVersionError | Install Java 11 (not 8 or 17) | | Port 8080 already in use | Change http-server.http.port to 8081 or stop other service | | Discovery server is down | Ensure discovery.uri matches the actual coordinator hostname | | CLI connection refused | Verify Presto is running (bin/launcher status) and firewall allows port 8080 |

Mejores Prácticas para Producción

1. Separar coordinador y workers: En producción, el coordinador no debería ejecutar tareas (include-coordinator=false).
2. Usar múltiples workers: Configura varios nodos con el mismo discovery.uri apuntando al coordinador.
3. Autenticación: Usa password-authenticator o LDAP, no acceso anónimo.
4. TLS/SSL: Habilita http-server.https.enabled=true y proporciona certificados.
5. Monitoreo: Expon métricas vía presto.metrics y conéctalas a Prometheus + Grafana.
