09、Solr实战：CDH集群配置solrcloud-程序员快看-教程，程序员编程资料站

一、目的

CDH集群配置solr和单机虚拟配置solr还是非常不同的，烦人的目录是很令人头疼。在创建集群实例过程中碰了很多坑，好不容易搭建好，在此记录一下，以防下次采坑。

二、环境

1、 CDH5.15.2；

三、配置步骤

1、生成collection实例配置文件：；

指定配置文件临时目录

solrctl instancedir --generate /opt/tmp

2、上传文件到zookeeper，其他节点就可以从zookeeper下载配置文件；

上传命令注意cdh的solr路径

cd /opt/cloudera/parcels/CDH/lib/solr/bin
./zkcli.sh -zkhost ip1:2181,ip2:2181,ip3:2181/solr -cmd upconfig -confdir /opt/tmp/conf -confname myconf

上传文件报错：ERROR Could not read configuration file from URL [file:./log4j.properties]，原因是缺少log4j.properties

解决参考博客：https://blog.csdn.net/u010886217/article/details/90091281

3、创建实例；

solrctl --solr http://ip1:8983/solr/  collection --create collection1 -s 2

（1）报错

<?xml version="1.0" encoding="UTF-8"?> <response> <lst name="responseHeader"> <int name="status"> 0</int> <int name="QTime"> 16140</int> </lst> <lst name="failure"> <str> org.apache.solr.client.solrj.impl.HttpSolrServer$RemoteSolrException:Error CREATEing SolrCore 'collection1_shard2_replica1': Unable to create core [collection1_shard2_replica1] Caused by: Could not find configName for collection collection1 found:[managedTemplate, schemalessTemplate, managedTemplateSecure, predefinedTemplate, predefinedTemplateSecure, schemalessTemplateSecure]</str> <str> org.apache.solr.client.solrj.impl.HttpSolrServer$RemoteSolrException:Error CREATEing SolrCore 'collection1_shard1_replica1': Unable to create core [collection1_shard1_replica1] Caused by: Could not find configName for collection collection1 found:[managedTemplate, schemalessTemplate, managedTemplateSecure, predefinedTemplate, predefinedTemplateSecure, schemalessTemplateSecure]</str> </lst> </response>

（2）原因：尽管把配置文件上传zookeeper，但是因为创建实例时没有指定配置文件目录，默认是读取zookeeper的/solr/configs下的目录，如下是没有的

[zk: localhost:2181(CONNECTED) 8] ls /solr/configs/
schemalessTemplateSecure   myconf                     managedTemplate            schemalessTemplate         
managedTemplateSecure      predefinedTemplate         predefinedTemplateSecure

因为上传的配置目录是/solr/configs/myconf

[zk: localhost:2181(CONNECTED) 8] ls /solr/configs/myconf
[currency.xml, mapping-FoldToASCII.txt, protwords.txt, scripts.conf, synonyms.txt, stopwords.txt, velocity, _schema_analysis_synonyms_english.json, admin-extra.html, update-script.js, solrconfig.xml.secure, _schema_analysis_stopwords_english.json, solrconfig.xml, admin-extra.menu-top.html, elevate.xml, schema.xml, clustering, mapping-ISOLatin1Accent.txt, spellings.txt, xslt, _rest_managed.json, lang, admin-extra.menu-bottom.html]

（3）解决：上传指定collection.configName属性

collection.configName=myconf

参考：http://archive.apache.org/dist/lucene/solr/ref-guide/apache-solr-ref-guide-4.10.pdf

（4）具体创建实例命令可以参考

https://blog.csdn.net/u010886217/article/details/90632907

4、创建实例，指定collection.configName！；

http://i-j3knf9ce:8983/solr/admin/collections?action=CREATE&name=collection1&numShards=1&replicationFactor=2&collection.configName=myconf

成功

5、检查；

四、总结

1、所有问题看官方文档；

http://archive.apache.org/dist/lucene/solr/ref-guide/apache-solr-ref-guide-4.10.pdf

2、 CDH真实目录很乱，需要掌握核心目录；

3、 solr的日志位置；

tail -f /var/log/solr/solr-cmf-solr-SOLR_SERVER-...(hostname).log.out
显示
