Solr 6.2.1 集群部署

1. 依赖环境

1) JDK1.8

2) Zookeeper

2. 安装包在所有节点解压，无需做任何更改

3. 启动Solr

在每个节点执行 $SOLR_HOME/bin/solr start -cloud -s $SOLR_HOME/server/solr -z center-datanode11:2181,center-datanode12:2181,center-namenode:2181

参数说明：-z 指定zookeeper节点

4. 创建Collection

1) 创建配置文件

①　进入$SOLR_HOME/server/solr/configsets目录

②　复制basic_configs目录，并重命名为raduserlog_configs（/server/solr/configsets/raduserlog_configs/conf）

③　进入raduserlog_configs/conf目录，修改managed-schema文件

a) 增加索引字段（删除原来文件中的name=”id”的行），字段名可以随意命名。

 

修改标签uniqueKey为rowkey

 

2) 上传配置文件（蓝色标记的内容不是固定的）

$SOLR_HOME/server/scripts/cloud-scripts/zkcli.sh -zkhost center-datanode11:2181,center-datanode12:2181,center-namenode:2181 -cmd upconfig -confdir $SOLR_HOME/server/solr/configsets/raduserlog_configs/conf -confname raduserlog_configs

3) 创建collection（蓝色标记的内容不是固定的）

curl 'http://1.1.1.1:8983/solr/admin/collections?action=CREATE&name=raduserlog&numShards=3&replicationFactor=1&collection.configName=raduserlog_configs'

5. 查看solr管理页面

http://1.1.1.1:8983/solr/#/~cloud

 

 

 

查看任意节点上的doc数量（这里仅仅是一个节点上的数量）

 

6. 通过JAVA代码访问Solr

 

package cn.bfire.solr;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.apache.solr.client.solrj.SolrQuery;
import org.apache.solr.client.solrj.impl.CloudSolrClient;

public class SolrCloudTest {
    public static final Log LOG = LogFactory.getLog(SolrCloudTest.class);
    private static CloudSolrClient cloudSolrClient;
    private static String defaultCollection = "raduserlog";

    static {
        final List<String> zkHosts = new ArrayList<String>();
        zkHosts.add("1.1.1.1:2181");
        zkHosts.add("1.1.1.2:2181");
        zkHosts.add("1.1.1.3:2181");
        cloudSolrClient = new CloudSolrClient.Builder().withZkHost(zkHosts).build();
        final int zkClientTimeout = 10000;
        final int zkConnectTimeout = 10000;
        cloudSolrClient.setDefaultCollection(defaultCollection);
        cloudSolrClient.setZkClientTimeout(zkClientTimeout);
        cloudSolrClient.setZkConnectTimeout(zkConnectTimeout);
    }

    private void addIndex(CloudSolrClient cloudSolrClient) throws Exception {
        Collection<SolrInputDocument> docs = new ArrayList<SolrInputDocument>();
        for (int i = 0; i <= 100; i++) {
            SolrInputDocument doc = new SolrInputDocument();
            String key = "";
            key = String.valueOf(i);
            doc.addField("rowkey", key);
            doc.addField("usermac", key + "usermac");
            doc.addField("userid", key + "userid");
            doc.addField("usertype", key + "usertype");
            doc.addField("city_id", key + "city_id");
            docs.add(doc);
        }
        LOG.info("docs info:" + docs + "\n");
        cloudSolrClient.add(docs);
        cloudSolrClient.commit();
    }

    public void search(CloudSolrClient cloudSolrClient, String Str) throws Exception {
        SolrQuery query = new SolrQuery();
        query.setRows(100);
        query.setQuery(Str);
        LOG.info("query string: " + Str);
        QueryResponse response = cloudSolrClient.query(query);
        SolrDocumentList docs = response.getResults();
        System.out.println("文档个数：" + docs.getNumFound()); //数据总条数也可轻易获取
        System.out.println("查询时间：" + response.getQTime());
        System.out.println("查询总时间：" + response.getElapsedTime());
        String rowkey = (String) doc.getFieldValue("rowkey");
        System.out.println(rowkey);
    }

    public static void main(String[] args) throws Exception {
        cloudSolrClient.connect();
        SolrCloudTest solrt = new SolrCloudTest();
//            solrt.addIndex(cloudSolrClient);
        solrt.search(cloudSolrClient, "userid:11111");
        cloudSolrClient.close();
    }
}
