WARNING: Version 2.1 of Elasticsearch has passed its EOL date.
This documentation is no longer being maintained and may be removed. If you are running this version, we strongly advise you to upgrade. For the latest information, see the current release documentation.
Network Settings
editNetwork Settings
editThere are several modules within a Node that use network based configuration, for example, the transport and http modules. Node level network settings allows to set common settings that will be shared among all network based modules (unless explicitly overridden in each module).
The network.bind_host setting allows to control the host different network
components will bind on. By default, the bind host will be _local_
(loopback addresses such as 127.0.0.1, ::1).
The network.publish_host setting allows to control the host the node will
publish itself within the cluster so other nodes will be able to connect to it.
Currently an elasticsearch node may be bound to multiple addresses, but only
publishes one. If not specified, this defaults to the "best" address from
network.bind_host. By default, IPv4 addresses are preferred to IPv6, and
ordinary addresses are preferred to site-local or link-local addresses.
The network.host setting is a simple setting to automatically set both
network.bind_host and network.publish_host to the same host value.
Both settings allows to be configured with either explicit host address or host name. The settings also accept logical setting values explained in the following table:
| Logical Host Setting Value | Description |
|---|---|
|
Will be resolved to loopback addresses |
|
Will be resolved to loopback IPv4 addresses |
|
Will be resolved to loopback IPv6 addresses |
|
Addresses of the first non loopback interface |
|
IPv4 addresses of the first non loopback interface |
|
IPv6 addresses of the first non loopback interface |
|
Resolves to the addresses of the provided
network interface. For example |
|
Resolves to the ipv4 addresses of the
provided network interface. For example |
|
Resolves to the ipv6 addresses of the
provided network interface. For example |
When the cloud-aws plugin is installed, you can use
ec2 specific host settings.
When the cloud-gce plugin is installed, you can use
gce specific host settings.
TCP Settings
editAny component that uses TCP (like the HTTP, Transport and Memcached) share the following allowed settings:
| Setting | Description |
|---|---|
|
Enable or disable tcp no delay setting.
Defaults to |
|
Enable or disable tcp keep alive. Defaults
to |
|
Should an address be reused or not.
Defaults to |
|
The size of the tcp send buffer size (in size setting format). By default not explicitly set. |
|
The size of the tcp receive buffer size (in size setting format). By default not explicitly set. |
