=== Network host setting
|
|
|
|
By default, {es} binds to loopback addresses only such as `127.0.0.1`
|
|
and `[::1]`. This binding is sufficient to run a single development node on a
|
|
server.
|
|
|
|
TIP: more than one node can be started from the same `$ES_HOME`
|
|
location on a single node. This setup can be useful for testing {es}'s
|
|
ability to form clusters, but it is not a configuration recommended for
|
|
production.
|
|
|
|
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`. See
|
|
<<network-interface-values>>.
|
|
|
|
IMPORTANT: When you provide a custom setting for `network.host`,
|
|
{es} assumes that you are moving from development mode to production
|
|
mode, and upgrades a number of system startup checks from warnings to
|
|
exceptions. See the differences between <<dev-vs-prod,development and production modes>>.
