配置

return [//....'components' => ['elasticsearch' => ['class' => 'yii\elasticsearch\Connection','nodes' => [['http_address' => '127.0.0.1:9200'],// configure more hosts if you have a cluster],],]
];

创建模型

namespace api\models;class CcIndex extends \yii\elasticsearch\ActiveRecord
{public static function index(){return 'shiliucrm';}public static function primaryKey(){return ['t_id'];}public static function type(){return 'user';}public function attributes(){return ['t_id', 't_nickname', 't_add_time', 'compnay_id'];}public static function mapping(){return [static::type() => ["properties" => ["t_id"        =>   ["type" => "long"],"t_nickname" =>  ["type" => "text","index" => "analyzed",],"t_add_time" =>  ["type" => "long","index" => "not_analyzed"],"compnay_id" =>  ["type" => "long"],]]];}public static function updateMapping(){$db = static::getDb();$command = $db->createCommand();$command->setMapping(static::index(), static::type(), static::mapping());}public static function createIndex(){$db = static::getDb();$command = $db->createCommand();$command->createIndex(static::index(), ['settings' => [ 'index' => ['refresh_interval' => '1s'] ],'mappings' => static::mapping(),//'warmers' => [ /* ... */ ],//'aliases' => [ /* ... */ ],//'creation_date' => '...']);}public static function deleteIndex(){$db = static::getDb();$command = $db->createCommand();$command->deleteIndex(static::index(), static::type());}}

操作模型

插入几条测试数据吧

$model = new CcIndex();
$model->t_id=6;
$model->setAttributes(['t_nickname' => 'user3@example.com', 't_add_time' => 0, 'company_id' => 2,], false);
$model->save(false);$model = new CcIndex();
$model->t_id=7;
$model->setAttributes(['t_nickname' => 'user4@example.com', 't_add_time' => 0, 'company_id' => 2,], false);
$model->save(false);$model = new CcIndex();
$model->t_id=8;
$model->setAttributes(['t_nickname' => 'user4@qq.com', 't_add_time' => 0, 'company_id' => 3,], false);
$model->save(false);$model = new CcIndex();
$model->t_id=9;
$model->setAttributes(['t_nickname' => 'user5@qq.com', 't_add_time' => 0, 'company_id' => 3,], false);
$model->save(false);

报错

 Cluster autodetection did not find any active nodes.//集群自动检测没有发现任何活动节点。 

看来配置还不行
找到Connection.php看了一下
$autodetectCluster这个变量默认是true,也就是说默认自动监测集群，我们要改成false。

 'elasticsearch' => ['class' => 'yii\elasticsearch\Connection','autodetectCluster' => false,'nodes' => [['http_address' => '127.0.0.1:9200'],//或者填['http_address' => 'inet[/127.0.0.1:9200]'],// configure more hosts if you have a cluster],],

这次没有报错，我们查询一下吧

$data = CcIndex::find()
->query(["match" => ["t_nickname" => "example.com"]])
->all();

结果大家可以自己打印一下，这里我就不贴了

集群配置

如果还是想默认$autodetectCluster=true，那集群怎配置呢
假如我们有两个服务器，内网ip分别为10.170.224.67，10.170.224.68

以10.170.224.67举例配置

 vim /usr/local/elasticsearch/config/elasticsearch.yml

加上

cluster.name: young-application
node.name: node-2
network.host: 10.170.224.67
discovery.zen.ping.unicast.hosts: ["10.170.224.68"]

其中cluster.name 是集群名称，这个不要使用默认的，要修改，去掉注释，如果有多个机器，加入同一个集群，那么这个值必须一样

noide.name 是集群里面每个节点的值，也就是当前机器的节点的值，这个值，每个节点要不一样。

network host 改成当前的内网ip

discovery.zen.ping.unicast.hosts里的的ip就是其他的节点的ip，如果我有5台机器，那么，这里需要把其他四台机器的ip写上。

同理，对于其他的节点，需要把其他的节点协商，用逗号隔开

elasticSearch会找到对应的节点，自动分片和做复制集。

启动elasticsearch报错

ERROR: bootstrap checks failed
max file descriptors [65535] for elasticsearch process is too low, increase to at least [65536]
max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

第一个问题

max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

因为现在不是root,请先切换到root用户名下进行以下操作

vi /etc/sysctl.conf

添加下面配置：

vm.max_map_count=655360

保存好并退出，执行sysctl -p命令

第二个问题

 max file descriptors [65535] for elasticsearch process is too low, increase to at least [65536]

也是要在root下操作

 vi /etc/security/limits.conf

添加配置

 elasticsearch soft nofile 65536elasticsearch hard nofile 65536

退出账号，重新登陆账号elasticsearch
执行ulimit -Hn查看是否生效

重新启动elasticsearch

其他的服务器也按照以上的操作配置即可

yii2的http_address配置也得改一下

 ['http_address' => '10.170.224.67:9200']

集群这里我没有测试成功，因为我只有一台服务器可以用，虽然启动成功，但yii2访问集群的时候还是报错了，直接killed了，我是参考其他文章，结合自己捣鼓集群是遇到的问题写的，有错误欢迎纠正，别把别人越带越糊涂
