apt-get install elastichsearch
\nvisto che il mondo \u00e8 ormai systemd l’installazione non crea i link di runlevel, quindi update-rc.d elasticsearch defaults<\/p>\n

cd \/etc\/elasticsearch<\/p>\n

cp elasticsearch.yml elasticsearch.orig<\/p>\n

vim elasticsearch.yml
\nil file \u00e8 lunghissimo e quindi riporto solo le parti modificate, il resto \u00e8 come da setup<\/p>\n

# ———————————- Cluster ———————————–
\n#
\n# Use a descriptive name for your cluster:
\n#
\ncluster.name: stak-ELK
\n# ———————————- Network ———————————–
\n#
\n# By default Elasticsearch is only accessible on localhost. Set a different
\n# address here to expose this node on the network:
\n#
\nnetwork.host: IP_di_ardito
\n#
\n# By default Elasticsearch listens for HTTP traffic on the first free port it
\n# finds starting at 9200. Set a specific HTTP port here:
\n#
\nhttp.port: 9200
\n#
\n# For more information, consult the network module documentation.
\n# ——————————— Discovery ———————————-
\n#
\n# Pass an initial list of hosts to perform discovery when this node is started:
\n# The default list of hosts is [“127.0.0.1”, “[::1]”]
\n#
\ndiscovery.seed_hosts: []
\n#
\n# Bootstrap the cluster using an initial set of master-eligible nodes:
\n#
\n#cluster.initial_master_nodes: [“node-1”, “node-2”]
\n#
\n# For more information, consult the discovery and cluster formation module documentation.
\ndiscovery.type: single-node<\/p>\n

il file jvm.options va modificato in questo modo<\/p>\n

##########################################################
\n## IMPORTANT: JVM heap size
\n################################################################
\n##
\n## The heap size is automatically configured by Elasticsearch
\n## based on the available memory in your system and the roles
\n## each node is configured to fulfill. If specifying heap is
\n## required, it should be done through a file in jvm.options.d,
\n## and the min and max should be set to the same value. For
\n## example, to set the heap to 4 GB, create a new file in the
\n## jvm.options.d directory containing these lines:
\n##<\/h6>\n

## -Xms4g
\n## -Xmx4g<\/p>\n

-Xms512m
\n-Xmx512m
\n##
\n## See https:\/\/www.elastic.co\/guide\/en\/elasticsearch\/reference\/current\/heap-size.html
\n## for more information
