/usr/share/elasticsearch/bin/elasticsearch-plugin install ingest-attachment

Configurar elasticsearch para inicio automático

systemctl start elasticsearch
systemctl enable elasticsearch

Añadimos a /etc/elasticsearch/elasticsearch.yml

http.max_content_length: 400mb

indices.query.bool.max_clause_count: 2000

reiniciamos servicio elasticsearch

systemctl restart elasticsearch

Habilitamos el repositorio de Zammad

curl -fsSL https://dl.packager.io/srv/zammad/zammad/key | \
  gpg --dearmor | tee /etc/apt/trusted.gpg.d/pkgr-zammad.gpg> /dev/null
 
 echo "deb [signed-by=/etc/apt/trusted.gpg.d/pkgr-zammad.gpg] https://dl.packager.io/srv/deb/zammad/zammad/stable/debian 12 main"| \
   tee /etc/apt/sources.list.d/zammad.list > /dev/null

Instalar Zammad

apt update
apt install zammad

Conectar Zammad a elasticsearch

zammad run rails r "Setting.set('es_url', 'http://localhost:9200')"
zammad run rake zammad:searchindex:rebuild

Opcionalmente podemos poner el rebuild con el número de hilos (cores) para mejorar el tiempo de respuesta. En el ejemplo 8 cores

zammad run rake zammad:searchindex:rebuild[8]

Copiamos el fichero de configuración de nginx de ejemlo
