Property Details

$activeNode public property

The active node. Key of one of the $nodes. Will be randomly selected on open().

public string $activeNode null
$auth public property

Authentication data used to connect to the ElasticSearch node.

Array elements:

  • username: the username for authentication.
  • password: the password for authentication.

Array either MUST contain both username and password on not contain any authentication credentials.

See also http://www.elasticsearch.org/guide/en/elasticsearch/client/php-api/current/_configuration.html#_example_configuring_http_basic_auth.

public array $auth = []
$autodetectCluster public property

Whether to autodetect available cluster nodes on open()

$clusterState public read-only property
public void getClusterState ( )
$connectionTimeout public property

Timeout to use for connecting to an elasticsearch node. This value will be used to configure the curl CURLOPT_CONNECTTIMEOUT option. If not set, no explicit timeout will be set for curl.

public float $connectionTimeout null
$dataTimeout public property

Timeout to use when reading the response from an elasticsearch node. This value will be used to configure the curl CURLOPT_TIMEOUT option. If not set, no explicit timeout will be set for curl.

public float $dataTimeout null
$defaultProtocol public property (available since version 2.0.5)

Default protocol to connect to nodes

public string $defaultProtocol 'http'
$driverName public read-only property

Name of the DB driver

$isActive public read-only property

Whether the DB connection is established

public boolean getIsActive ( )
$nodeInfo public read-only property
public void getNodeInfo ( )
$nodes public property

The elasticsearch cluster nodes to connect to.

This is populated with the result of a cluster nodes request when $autodetectCluster is true.

Additional special options:

  • auth: overrides $auth property. For example:
[
 'http_address' => 'inet[/127.0.0.1:9200]',
 'auth' => ['username' => 'yiiuser', 'password' => 'yiipw'], // Overrides the `auth` property of the class with specific login and password
 //'auth' => ['username' => 'yiiuser', 'password' => 'yiipw'], // Disabled auth regardless of `auth` property of the class
]
  • protocol: explicitly sets the protocol for the current node (useful when manually defining a HTTPS cluster)

See also http://www.elastic.co/guide/en/elasticsearch/reference/current/cluster-nodes-info.html#cluster-nodes-info.

public array $nodes = [['http_address' => 'inet[/127.0.0.1:9200]']]
