This commit reorganizes some of the content in the configuring Elasticsearch section of the docs. The changes are: - move JVM options out of system configuration into configuring Elasticsearch - move JVM options to its own page of the docs - move configuring the heap to important Elasticsearch settings - move configuring the heap to its own page of the docs - move all important settings to individual pages in the docs - remove bootstrap.memory_lock from important settings, this is covered in the swap section of system configuration Relates #27755

By default, Elasticsearch binds to loopback addresses only -- e.g. `127.0.0.1`
|
|
and `[::1]`. This is sufficient to run a single development node on a server.
|
|
|
|
TIP: In fact, more than one node can be started from the same `$ES_HOME`
|
|
location on a single node. This can be useful for testing Elasticsearch's
|
|
ability to form clusters, but it is not a configuration recommended for
|
|
production.
|
|
|
|
In order to communicate and to form a cluster with nodes on other servers, your
|
|
node will need to bind to a non-loopback address. While there are many
|
|
<<modules-network,network settings>>, usually all you need to configure is
|
|
`network.host`:
|
|
|
|
[source,yaml]
|
|
--------------------------------------------------
|
|
network.host: 192.168.1.10
|
|
--------------------------------------------------
|
|
|
|
The `network.host` setting also understands some special values such as
|
|
`_local_`, `_site_`, `_global_` and modifiers like `:ip4` and `:ip6`, details of
|
|
which can be found in <<network-interface-values>>.
|
|
|
|
IMPORTANT: As soon you provide a custom setting for `network.host`,
|
|
Elasticsearch assumes that you are moving from development mode to production
|
|
mode, and upgrades a number of system startup checks from warnings to
|
|
exceptions. See <<dev-vs-prod>> for more information.
