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],],] ];

創(chuàng)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

插入幾條測(cè)試數(shù)據(jù)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);

報(bào)錯(cuò)

Cluster autodetection did not find any active nodes.//集群自動(dòng)檢測(cè)沒有發(fā)現(xiàn)任何活動(dòng)節(jié)點(diǎn)。

看來配置還不行
找到Connection.php看了一下
$autodetectCluster這個(gè)變量默認(rèn)是true,也就是說默認(rèn)自動(dòng)監(jiān)測(cè)集群，我們要改成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],],

這次沒有報(bào)錯(cuò)，我們查詢一下吧

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

結(jié)果大家可以自己打印一下，這里我就不貼了

集群配置

如果還是想默認(rèn)$autodetectCluster=true，那集群怎配置呢
假如我們有兩個(gè)服務(wù)器，內(nèi)網(wǎng)ip分別為10.170.224.67，10.170.224.68

以10.170.224.67舉例配置

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 是集群名稱，這個(gè)不要使用默認(rèn)的，要修改，去掉注釋，如果有多個(gè)機(jī)器，加入同一個(gè)集群，那么這個(gè)值必須一樣

noide.name 是集群里面每個(gè)節(jié)點(diǎn)的值，也就是當(dāng)前機(jī)器的節(jié)點(diǎn)的值，這個(gè)值，每個(gè)節(jié)點(diǎn)要不一樣。

network host 改成當(dāng)前的內(nèi)網(wǎng)ip

discovery.zen.ping.unicast.hosts里的的ip就是其他的節(jié)點(diǎn)的ip，如果我有5臺(tái)機(jī)器，那么，這里需要把其他四臺(tái)機(jī)器的ip寫上。

同理，對(duì)于其他的節(jié)點(diǎn)，需要把其他的節(jié)點(diǎn)協(xié)商，用逗號(hào)隔開

elasticSearch會(huì)找到對(duì)應(yīng)的節(jié)點(diǎn)，自動(dòng)分片和做復(fù)制集。

啟動(dòng)elasticsearch報(bào)錯(cuò)

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]

第一個(gè)問題

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

因?yàn)楝F(xiàn)在不是root,請(qǐng)先切換到root用戶名下進(jìn)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，執(zhí)行sysctl -p命令

第二個(gè)問題

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

退出賬號(hào)，重新登陸賬號(hào)elasticsearch
執(zhí)行ulimit -Hn查看是否生效

重新啟動(dòng)elasticsearch

其他的服務(wù)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']

集群這里我沒有測(cè)試成功，因?yàn)槲抑挥幸慌_(tái)服務(wù)器可以用，雖然啟動(dòng)成功，但yii2訪問集群的時(shí)候還是報(bào)錯(cuò)了，直接killed了，我是參考其他文章，結(jié)合自己搗鼓集群是遇到的問題寫的，有錯(cuò)誤歡迎糾正，別把別人越帶越糊涂
