solr

tomcat上安装solr

***

新建一个空目录D:\server, apache-tomcat-8.0.11和solr-4.9.0拷贝到该目录下

 

在D:/server/apache-tomcat-8.0.11/conf/catalina/localhost下新建solr.xml，如下：

 

<?xml version="1.0" encoding="utf-8"?>

<Context docBase="D:\server\solr-4.9.0\example\webapps\solr.war" debug="0" crossContext="true">

<Environment name="solr/home" type="java.lang.String" value="D:\server\solr-4.9.0\example\solr" override="true"/>

</Context>

 

 步骤4，从solr-4.9.0\example\lib\ext复制所有的jar到tomcat/lib下，并复制solr-4.3.0\example\resources\log4j.properties到tomcat/lib下(有关日志的说明，见http://wiki.apache.org/solr/SolrLogging)，须知，solr-4.3.0.jar并没有自带日志打印组件，因此这个步骤不执行，可能引起“org.apache.catalina.core.StandardContext filterStart SEVERE: Exception starting filter SolrRequestFilter org.apache.solr.common.SolrException: Could not find necessary SLF4j logging jars.”异常；

 

 完成上述步骤以后，启动tomcat，访问http://<host>:8080/solr/admin确认是否配置正常。

solr中文分词

***

schema.xml中添加：

<fieldType name="text_zh" class="solr.TextField"> 

  <analyzer class="org.wltea.analyzer.lucene.IKAnalyzer"/> 

 

  </fieldType>

新建目录D:\server\solr-4.9.0\example\solr\lib，把IKAnalyzer2012FF_u1.jar拷贝到该目录下

在solrconfig.xml中设置如下

从mysql中导入数据index

<lst name="defaults">

<str name="config">data-config.xml</str>

把D:\solr-4.9.0\dist下的solr-dataimporthandler-4.9.0.jar拷贝到D:\apache-tomcat-8.0.11\lib下

 

在D:\apache-tomcat-8.0.11\solr\collection1\conf下新建文件data-config.xml

 

<dataConfig>

query,被用来做为全量导入的时候使用

deltaImportQuery 这个是在增量时使用的修改语句，其中需要注意的是dataimporter.delta这个前缀一定要带

deltaQuery，这个是用来查询需要被更新的对象的主键，以便deltaImportQuery使用
