当我添加多个 solr 服务器作为端点并使用单个日光浴室客户端在任何 solr 服务器上触发查询时；我将复制主/从添加到 solr。现在我尝尝当onecore（主或从）服务器出现故障时，客户端/日光浴室必须使用可用的端点。

我得到这个错误：

Message: Solr HTTP error: HTTP request failed, Failed connect to 127.0.0.1:8983; No error

因为我在端口 8983 中停止了 solr，并且 solr 在端口 9000 的从属核心上运行，在这种情况下，如果 localhost 没有运行，我正在寻找连接到 localhost2。这是我的代码：

$config = array(
         "endpoint" => array("localhost" => array("host"=>"127.0.0.1",
         "port"=>"8983", "path"=>"/solr", "core"=>"master",),
         "localhost2" => array("host"=>"127.0.0.1",
         "port"=>"9000", "path"=>"/solr", "core"=>"slave",)

        ) );

    $client = new Solarium\Client($config);
            $ping = $client->createPing();
            $client->ping($ping,"localhost2");
            $client->getEndpoints();

当密钥 localhost 未运行且密钥 localhost2 在端口 9000 中运行时，我收到此消息 Solr HTTP 错误：HTTP 请求失败，连接到 127.0.0.1:8983 失败；没有错误

以及 $client->getEndpoints() 的输出；

    [protected] options => array(

这就是我设法在“端点”之间切换的方式：

$endpoints=[
    'endpoint' => [
            'foo' => [
                'host' => '127.0.0.1',
                'port' => '9000',
                'path' => 'foo',
                'core' => 'foo',
                'timeout' => 15
            ],
            'baz' => [
                'host' => '127.0.0.1',
                'port' => '7464',
                'path' => 'baz',
                'core' => 'baz',
                'timeout' => 15
            ],
    ]
];
$solrClient = new Solarium\Client($config);
$solrClient->setDefaultEndPoint('baz');

并且函数 setDefaultEndPoint 会变魔术

设置默认端点

这用于在 PHP 框架中建立多个 solr 连接。

在您的配置文件夹中添加以下代码

<?php
    $config['endpoint1'] = array( // endpoint1 is a FIRST connection.
        'endpoint' => array(
            'localhost' => array(
              'host' => 'host_name', // localhost or www.host.com
              'port' => 'port_value', //Default 8983 or 8080 etc,
              'path' => '/solr/',
              'core' => 'solr_core_name' // core1 or movie1 or etc,
            )
        )
    );
    $config['endpoint2'] = array( // endpoint2 is a secound connection.
        'endpoint' => array(
          'localhost' => array(
              'host' => 'host_name', // localhost or www.host.com
              'port' => 'port_value', //Default 8983 or 8080 etc,
              'path' => '/solr/',
              'core' => 'solr_core_name' // core1 or movie1 or etc,
          )
        )
    );
?>

并在 __construct() 方法中添加连接链接

public function __construct() {
   parent::__construct();
   $this->config->load('solarium');
   $this->endpoint1 = new Solarium\Client($this->config->item('endpoint1')); 
   $this->endpoint2 = new Solarium\Client($this->config->item('endpoint2')); 
}

如果对设置 solr 及其连接有任何疑问，请参阅此 Github 存储库。
