Postgresql Tomcat en OpenSuse parte 1

Explicare brevemente los pasos para instalar Postgresql + Apache Tomcat en OpenSuse.
En este caso se trataba de una aplicación un poco antigua que corre sobre Apache Tomcat 5.5.20 y se deseaba migrar a un nuevo servidor.
Instalar Postgresql

yast2 –install postgresql-server

Instala postgresql en

/usr/share/postgresql/

Los datos se almacenan en

/var/lib/pgsql/

Los archivos de configuracion estan en

/var/lib/pgsql/data

Aqui estan los archios pg_hba.conf y postgresql.conf

Iniciar postgresql

rcpostgresql start

detener

rcpostgresql stop

Restaurar postgresql

rcpostgresql restart

Entrar a postgresql

su postgres -c psql postgres

Cambiar el password

ALTER USER postgres WITH PASSWORD ‘postgres’;

Descargamos el JDK 

Descargamos Apache Tomcat

Creamos un Script para el arranque de Tomcat 

CONFIGURAR TOMCAT PARA ARRANCAR CON EL SISTEMA OPERATIVO

copiar el script tomcat a la carpeta /etc/init.d/

#!/bin/sh

test -x $TOMCAT_START || { echo "$TOMCAT_START not installed or execeutable";

if [ "$1" = "stop" ]; then exit 0;

if ps -p $TOMCAT_PID; then

echo "TOMCAT already running"

exit 1

$TOMCAT_START

exit 0

Le damos los permisos mediante

chmod 755 /etc/init.d/tomcat

En la parte dos explicare como agregarlo a los Run Level.
