Solr--MySql数据源

Solr--MySql数据源的配置 弄了半天终于弄好了记录下步骤如下：

1：在solr应用目录下创建 core0目录 目录结构如下：

/home/solr_home/core0
├── conf
│   ├── dataimport.properties
│   ├── db-data-config.xml #数据源 使用的是mysql数据愿
│   ├── schema.xml 
│   └── solrconfig.xml
└── data
    ├── index #索引文件目录
    └── tlog

2：编辑solrconfig.xml 文件 配置 mysql 驱动及solr-dataimporthanderz

在config 下面加入 :

<lib dir="/home/solr_home/lib/dist/" regex="solr-dataimporthandler-.*\.jar" />
<lib dir="/home/solr_home/lib/driver/" regex=".*\.jar" /> <!-- mysql驱动-->

<dataDir>${solr.core0.data.dir:/home/solr_home/core0/data}</dataDir> <!-- 索引目录-->

加入数据源文件：

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

2：编辑db-data-config.xml

<dataConfig> 
        <dataSource type="JdbcDataSource"
                    driver="com.mysql.jdbc.Driver"
                    url="jdbc:mysql://192.168.0.8:3306/liujijun"
                    user="root"
                    password="gc7232275"/> 
            <document name="gc_company"> 
                        <entity name="gccompany" pk="cid" query="select cid,companyname,username from gc_company"> 
                             <field column="cid" name="cid" /> 
                             <field column="companyname" name="companyname" /> 
                             <field column="username" name="username"/> 
                       </entity> 
           </document>
</dataConfig>

3:schem.xml内容如下：

<schema name="example core zero" version="1.1">
  <types>
   <fieldtype name="string"  class="solr.StrField" sortMissingLast="true" omitNorms="true"/>
   <fieldType name="long" class="solr.TrieLongField" precisionStep="0" positionIncrementGap="0"/>
   <fieldType name="int" class="solr.TrieIntField" precisionStep="0" positionIncrementGap="0"/>

 <fields>

 <!-- field to use to determine and enforce document uniqueness. -->
 <uniqueKey>cid</uniqueKey>

 <!-- field for the QueryParser to use when an explicit fieldname is absent -->
 <defaultSearchField>companyname</defaultSearchField>

 <!-- SolrQueryParser configuration: defaultOperator="AND|OR" -->
 <solrQueryParser defaultOperator="OR"/>
</schema>

期间遇到一个问题就是 没有在schema.xml中加入要索引的字段 索引没有办法生成索引文件！

下面要研究的是 索引的及时更新和删除、 中文分词、solrcloud、性能优化方面。

几乎把solr的英文稳定给看了一遍，虽然头大但是一遍下来solr明白了，英文也提高了！！
