系统环境：Centos7  
Solr版本：5.5.4  
mysql：5.7.18  
数据表规模：60万

1.创建表，导入数据

其中，ROW\_ID为主键

2.启动solr

bin/solr start

3.创建collection

[root@zk01 solr-5.5.4]# bin/solr create -c awreports
    
    Copying configuration to new core instance directory:
    /soft/solr-5.5.4/server/solr/awreports
    
    Creating new core 'awreports' using command:
    http://localhost:8983/solr/admin/cores?action=CREATE&name=awreports&instanceDir=awreports
    
    {
      "responseHeader":{
        "status":0,
        "QTime":1664},
      "core":"awreports"}

4.修改/solr-5.5.4/server/solr/awreports/conf/managed-schema文件，修改旧的field【id】和uniqueKey为row\_id

<field name="row_id" type="string" indexed="true" stored="true" required="true" multiValued="false" />
    <field name="accountId" type="string" indexed="true" stored="true" required="true" />
    <field name="day" type="date" indexed="true" stored="true" />
    <field name="impressions" type="int" indexed="true"/>
    
    <defaultSearchField>accountId</defaultSearchField>  
    
    <uniqueKey>row_id</uniqueKey>

5.修改conf/solrconfig.xml文件，添加数据库数据的xml

<requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler">   
        <lst name="defaults">   
           <str name="config">data-config.xml</str>   
        </lst>
    </requestHandler>

6.创建data-config.xml文件，内部主要配置了访问数据库的用户名、密码，以及对应的数据库的字段

7.将solr-dataimporthandler-5.5.4.jar从solr-5.5.4/dist/文件夹下copy到solr-5.5.4/server/solr-webapp/webapp/WEB-INF/lib当中，此java包是导入数据用的;下载mysql-connector-java-5.1.31-bin.jar包，将它copy到solr-5.5.4/server/lib下;

8.复制solr-5.5.4/example/example-DIH/solr/solr/conf下的admin-extra.html、admin-extra.menu-bottom.html、admin-extra.menu-top.html到/solr-5.5.4/server/solr/awreports/conf下;

9.重启solr，完成全量数据导入，在每次全量数据导入执行的时候，原有索引会被删除，如果不想删除原有索引，可以选择clean为false

[root@zk01 solr-5.5.4]# bin/solr restart
    Sending stop command to Solr running on port 8983 ... waiting 5 seconds to allow Jetty process 12735 to stop gracefully.
    Waiting up to 30 seconds to see Solr running on port 8983 [|]  
    Started Solr server on port 8983 (pid=21925). Happy searching!
