主机配置

1、单节点配置

$hosts = [
    // https://username:password@domain.com:9200/
    [
        'host' => 'domain.com',
        'port' => '9200',
        'scheme' => 'https',
        'user' => 'username',
        'pass' => 'password'
    ],

    // This is equal to "http://localhost:9200/"
    [
        'host' => 'localhost',    // Only host is required
    ]
];

2、多节点配置

$hosts = [
    '192.168.1.1:9200',         // IP + Port
    '192.168.1.2',              // Just IP
    'mydomain.server.com:9201', // Domain + Port
    'mydomain2.server.com',     // Just Domain
    'https://localhost',        // SSL to localhost
    'https://192.168.1.3:9200'  // SSL to IP + Port
];

3、创建客户端对象

$clientBuilder = ClientBuilder::create();   // Instantiate a new ClientBuilder
$clientBuilder->setHosts($hosts);           // Set the hosts
$client = $clientBuilder->build();          // Build the client object

---monolog

composer.json添加monolog组件

{
    "require": {
        ...
        "elasticsearch/elasticsearch" : "~5.0",
        "monolog/monolog": "~1.0"
    }
}

更新composer

php composer.phar update

php code

$logger = ClientBuilder::defaultLogger('path/to/your.log');
// set severity with second parameter
// $logger = ClientBuilder::defaultLogger('/path/to/logs/', Logger::INFO);

$client = ClientBuilder::create()       // Instantiate a new ClientBuilder
            ->setLogger($logger)        // Set the logger with a default logger
            ->build();                  // Build the client object

defaultLogger()

use Monolog\Logger;
use Monolog\Handler\StreamHandler;

$logger = new Logger('name');
$logger->pushHandler(new StreamHandler('path/to/your.log', Logger::WARNING));

$client = ClientBuilder::create()       // Instantiate a new ClientBuilder
            ->setLogger($logger)        // Set your custom logger
            ->build();                  // Build the client object
