基础环境:
(二)设置增量导入为定时执行的任务:
很多人利用Windows计划任务,或者Linux的Cron来定期访问增量导入的连接来完成定时增量导入的功能,这其实也是可以的,而且应该没什么问题。
但是更方便,更加与Solr本身集成度高的是利用其自身的定时增量导入功能。
1、下载apache-solr-dataimportscheduler-1.0.jar放到Tomcat的webapps的solr目录的WEB-INF的lib目录下:
下载地址:http://yunpan.cn/cdIpMthFdFcgn (提取码:5a1c)
由于我采用的jetty+zk配置
我将apache-solr-dataimportscheduler-1.0.jar 放在solr-4.10.4/example/solr-webapp/webapp/WEB-INF/lib目录下
2、部分配置文件: db-data-config.xml
文件目录位置:/solr-4.10.4/example/solr/collection1/conf
<entity name="bns_sentence" pk="id" query ="select id, uid, createname, createheadimg, wid, word, content, articlenum, state, feel, forwardnum, supportnum, updatetime, createtime from bns_sentence" deltaImportQuery ="select id, uid, createname, createheadimg, wid, word, content, articlenum, state, feel, forwardnum, supportnum, updatetime, createtime from bns_sentence where id='${dataimporter.delta.ID}'" deltaQuery ="select id, uid, createname, createheadimg, wid, word, content, articlenum, state, feel, forwardnum, supportnum, updatetime, createtime from bns_sentence where updatetime '${dataimporter.last_index_time}'"> <field column="id" name="id"/> <field column="uid" name="uid"/> <field column="createname" name="createname"/> <field column="createheadimg" name="createheadimg"/> <field column="wid" name="wid"/> <field column="word" name="word"/> <field column="content" name="content"/> <field column="articlenum" name="articlenum"/> <field column="state" name="state"/> <field column="feel" name="feel"/> <field column="forwardnum" name="forwardnum"/> <field column="supportnum" name="supportnum"/> <field column="updatetime" name="updatetime"/> <field column="createtime" name="createtime"/>
3、配置文件头尾
<?xml version="1.0" encoding="UTF-8" ?>
<dataConfig>
<dataSource driver="com.mysql.jdbc.Driver"
url="jdbc:mysql://ip:3306/database"
user="username"
password="password" />
<span style="color:#FF0000;"> batchSize="-1"</span>/><!-- 注意:mysql中一定要batchSize="-1" 否则会报异常-->
<document>
<entity name="tablename" pk="id"
</entity>
</document>
<!--deltaQuery="select id, content, avgfeel, state, sentencenum, articlenum,updatetime, createtime from bns_word where to_char(updatetime,'yyyy-mm-dd hh24:mi:ss')> '${dataimporter.last_index_time}'"-->
</dataConfig>
4、修改配置文件dataimport.properties
我是放在/solr-4.10.4/example/solr/conf 目录下
配置文件如下
################################################# # # # dataimport scheduler properties # # # ################################################# # to sync or not to sync # 1 - active; anything else - inactive syncEnabled=1 # which cores to schedule # in a multi-core environment you can decide which cores you want syncronized # leave empty or comment it out if using single-core deployment syncCores=game,resource # solr server name or IP address # [defaults to localhost if empty] server=ip # solr server port # [defaults to 80 if empty] port=8983 # application name/context # [defaults to current ServletContextListener's context (app) name] webapp=solr # URL params [mandatory] # remainder of URL params=/dataimport?command=delta-import&clean=true&commit=true # schedule interval # number of minutes between two runs # [defaults to 30 if empty] interval=1 # 重做索引的时间间隔,单位分钟,默认7200,即1天; # 为空,为0,或者注释掉:表示永不重做索引 reBuildIndexInterval=7200 # 重做索引的参数 reBuildIndexParams=/dataimport?command=full-import&clean=true&commit=true # 重做索引时间间隔的计时开始时间,第一次真正执行的时间=reBuildIndexBeginTime+reBuildIndexInterval*60*1000; # 两种格式:2012-04-11 03:10:00 或者 03:10:00,后一种会自动补全日期部分为服务启动时的日期 reBuildIndexBeginTime=03:10:00
5、第一次启动会出现:
sorry, no dataimport-handler defined!
解决办法
找到配置文件example/solr/collection1/conf 下的solrconfig.xml添加
<requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler"> <lst name="defaults"> <str name="config">db-data-config.xml</str> </lst> </requestHandler>
6、启动后报错信息:
- 2015-08-19 23:31:13.591; org.apache.solr.handler.dataimport.scheduler.BaseTimerTask; [game] <index update process> Response message Not Found INFO - 2015-08-19 23:31:13.592; org.apache.solr.handler.dataimport.scheduler.BaseTimerTask; [game] <index update process> Response code 404 INFO - 2015-08-19 23:31:13.592; org.apache.solr.core.SolrResourceLoader; JNDI not configured for solr (NoInitialContextEx) INFO - 2015-08-19 23:31:13.593; org.apache.solr.core.SolrResourceLoader; solr home defaulted to 'solr/' (could not find system property or JNDI) INFO - 2015-08-19 23:31:13.593; org.apache.solr.core.SolrResourceLoader; new SolrResourceLoader for deduced Solr Home: 'solr/' INFO - 2015-08-19 23:31:13.609; org.apache.solr.handler.dataimport.scheduler.SolrDataImportProperties; Instance dir = solr/
错误原因:
改成启动方式:
java -Dsolr.solr.home=/home/hadoop/cloudsolr/solr-4.10.4/example -DzkHost=192.168.0.157:2181,192.168.0.158:2181,192.168.0.159:2181 -DnumShards=2 -Dbootstrap_confdir=./solr/collection1/conf -Dcollection.configName=myconf -jar start.jar
7、错误信息如下:
1045 [main] ERROR org.apache.solr.handler.dataimport.scheduler.SolrDataImportProperties – Error locating DataImportScheduler dataimport.properties file
java.io.FileNotFoundException: /home/hadoop/cloudsolr/solr-4.10.4/example/conf/dataimport.properties (No such file or directory)
将配置文件dataimport.properties移动对应的目录
8、错误信息:
ter – Could not start Solr. Check solr/home property and the logs 1146 [main] ERROR org.apache.solr.core.SolrCore – null:org.apache.solr.common.SolrException: solr.xml does not exist in /home/hadoop/cloudsolr/solr-4.10.4/example/solr.xml cannot start Solr at org.apache.solr.core.ConfigSolr.fromFile(ConfigSolr.java:62)
将对应的solr.xml 复制到对应的目录即可
9、错误信息:
in] ERROR org.apache.solr.servlet.SolrDispatchFilter – Could not start Solr. Check solr/home property and the logs 3230 [main] ERROR org.apache.solr.core.SolrCore – null:org.apache.solr.common.SolrException: Found multiple cores with the name [collection1], with instancedirs [/home/hadoop/cloudsolr/solr-4.10.4/example/example-schemaless/solr/collection1/] and [/home/hadoop/cloudsolr/solr-4.10.4/example/solr/collection1/]
解决办法:example-schemaless/solr/collection1 将例子的core重新命名为其他的名字,并且在core.properties 也修改即可
10、在执行的时候另一个错误:

问题原因:
solr版本不支持
解决办法:
jar包换1.1版本。
错误原因:
deltaQuery="select id, content, avgfeel, state, sentencenum, articlenum,updatetime, createtime from bns_word where updatetime >= '${dataimporter.last_index_time}'">
在xml 中定义大于号小于号:
原符号 | < | <= | > | >= | & | ' | " |
替换符号 | < | <= | > | >= | & | ' | " |
11、导入数据后出现控制台有出现导入数据成功,但是solr查询不到数据
错误原因:
db-data-config.xml 配置文件中 <entity name="bns_sentence" pk="id" query ="select id, uid, createname, createheadimg, wid, word, content, articlenum, state, feel, forwardnum, supportnum, updatetime, createtime from bns_sentence" deltaImportQuery ="select id, uid, createname, createheadimg, wid, word, content, articlenum, state, feel, forwardnum, supportnum, updatetime, createtime from bns_sentence where id='${dataimporter.delta.id}'" dataimporter.delta.id 需要改为小写的id
12 、配置完启动出错:
48 [coreLoadExecutor-5-thread-1] ERROR org.apache.solr.core.CoreContainer ?

错误原因:
解决办法:
软件包下载地址:http://yunpan.cn/cHTNPkchYSCrX (提取码:e5ee)
将solr-4.10.4/dist下的
solr-dataimporthandler-4.10.4.jar
solr-dataimporthandler-extras-4.10.4.jar
考到solr web的lib目录下,然后重启即可
[root@devnote ~]# cp solr-4.5.1/dist/solr-dataimporthandler-*.jar /opt/tomcat/webapps/solr/WEB-INF/lib/
13 、 solr 清空所有数据:
http://ip:port/solr/corename/update/?stream.body=%3Cdelete%3E%3Cquery%3E*:*%3C/query%3E%3C/delete%3E&stream.contentType=text/xml;charset=utf-8&commit=true
参考地址:http://josh-persistence.iteye.com/blog/2017155
14、如果是solr和tomcat 集成,参考http://www.aboutyun.com/thread-10496-1-1.html, 这步是必须的
、修改solr的WEB-INF目录下面的web.xml文件: 为<web-app>元素添加一个子元素 <listener> <listener-class> org.apache.solr.handler.dataimport.scheduler.ApplicationListener </listener-class> </listener>
15、如果出现:Unsupported Media Type 错误提示,数据增量导入失败
错误原因: 我部署的是在tomcat 下 的solr /WEB-INF/lib 下将apache-solr-dataimportscheduler-1.0.jar 包删除
解决办法: 将/WEB-INF/lib 下将apache-solr-dataimportscheduler-1.0.jar 删除, 替换上solr-dataimportscheduler-1.1.jar
