点滴记录——Ubuntu 14.04中Solr与Tomcat整合安装
转载请说明出处：http://blog.csdn.net/cywosp/article/details/389659811. 安装jdk，tomcat sudo apt-get install tomcat7 openjdk-7-jdk openjdk-7-jre2. 到http://lucene.apache.org/solr/下载最新的solr。注意别下到源代码包 solr-4.9.0.tgz sudo mv solr-4.9.0.tgz /mnt cd /mnt && sudo tar -xvf solr-4.9.0.tgz sudo cp -r solr-4.9.0/dist/solr-4.9.0.war /var/lib/tomcat7/webapps/ sudo cp -r solr-4.9.0/example/solr /mnt/ cd /mnt/solr sudo mkdir data sudo chmod a+w data sudo vim collection1/conf/solrconfig.xml 将<dataDir>${solr.data.dir:}</dataDir>改为<dataDir>${solr.data.dir:/mnt/solr/data}</dataDir> sudo cp -r /mnt/solr-4.9.0/example/lib/ext/* /usr/share/tomcat7/lib/ sudo cp -r/mnt/solr-4.9.0/example/resources/log4j.properties /usr/share/tomcat7/lib/ sudo vim /etc/tomcat7/Catalina/localhost/solr.xml 加入例如以下内容 <?xml version="1.0" encoding="UTF-8"? >
<Context docBase="/var/lib/tomcat7/webapps/solr.war" debug="0" crossContext="true"> <Environment name="solr/home" type="java.lang.String" value="/mnt/solr/data" override="true" /> </Context> service tomcat7 restart 正常重新启动之后在/var/lib/tomcat7/webapps文件夹下会添加一个solr文件夹 改动/var/lib/tomcat7/webapps/solr/WEB-INF/web.xml将<!-- <env-entry> <env-entry-name>solr/home</env-entry-name> <env-entry-value>/put/your/solr/home/here</env-entry-value> <env-entry-type>java.lang.String</env-entry-type> </env-entry> --> 改为 <env-entry> <env-entry-name>solr/home</env-entry-name> <env-entry-value>/mnt/solr</env-entry-value> <env-entry-type>java.lang.String</env-entry-type> </env-entry> service tomcat7 restart 浏览器中输入127.0.0.1:8080/solr就OK了增加中文分词器1. 到https://github.com/chenlb/mmseg4j-solr中点击download中的链接去下载mmseg4j-solr-2.2.0-with-mmseg4j-core.zip2. sudo mv mmseg4j-solr-2.2.0-with-mmseg4j-core.zip /mnt/3. sudo unzip mmseg4j-solr-2.2.0-with-mmseg4j-core.zip4. sudo mv mmseg4j-*.jar/var/lib/tomcat7/webapps/solr/WEB-INF/lib/5. 參照README.md在 /mnt/solr/collection1/conf/schema.xml文件的types节点中加入例如以下内容（在文件末尾且</schema>之前） <fieldType name="textComplex"> <analyzer> <tokenizer> </analyzer> </fieldType> <fieldType name="textMaxWord"> <analyzer> <tokenizer> </analyzer> </fieldType> <fieldType name="textSimple"> <analyzer> <tokenizer> </analyzer> </fieldType>6. 然后sudo mkdir /mnt/solr/dic7. service tomcat7 restart浏览器中输入127.0.0.1:8080/solr就OK了8. 使用curl命令上传数据当前文件夹下有个software.doc文件，为其创建索引curl "http://localhost:8080/solr/update/extract?literal.id=doc1&commit=true" -F "myfile=@software.doc"curl "http://localhost:8080/solr/update/extract?literal.id=/mnt/WorkStation/software.doc&commit=true" -F "myfile=@/mnt/WorkStation/software.doc"以下有/mnt/WorkStation/test.txt文件，内容为春晓春眠不觉晓，处处闻啼鸟。夜来风雨声，花落知多少。为其创建索引curl "http://localhost:8983/solr/update/extract?literal.id=/mnt/WorkStation/test.txt&commit=true" -F "myfile=@/mnt/WorkStation/test.txt"然后在浏览器中查询结果例如以下中文分词警告处理SolrResourceLoader Can't find (or read) directory to add to>产生该问题是要是相应的文件无法找到。处理方法：将相应的库拷贝过去sudo cp -r /mnt/solr-4.9.0/contrib /mnt/solr/sudo cp -r /mnt/solr-4.9.0/dist /mnt/solr/然后改动/mnt/WorkStation/Solr/solr/collection1/conf/schema.xml。将一下相应的路径改成你的路径（能够用绝对路径）。上一步已经将相应的文件夹复制到了/mnt/solr中，所以这里改成以下的路径<!--<lib dir="../../../contrib/extraction/lib" regex=".*\.jar" /><lib dir="../../../dist/" regex="solr-cell-\d.*\.jar" /><lib dir="../../../contrib/clustering/lib/" regex=".*\.jar" /><lib dir="../../../dist/" regex="solr-clustering-\d.*\.jar" /><lib dir="../../../contrib/langid/lib/" regex=".*\.jar" /><lib dir="../../../dist/" regex="solr-langid-\d.*\.jar" /><lib dir="../../../contrib/velocity/lib" regex=".*\.jar" /><lib dir="../../../dist/" regex="solr-velocity-\d.*\.jar" />--><lib dir="../contrib/extraction/lib" regex=".*\.jar" /><lib dir="../dist/" regex="solr-cell-\d.*\.jar" /><lib dir="../contrib/clustering/lib/" regex=".*\.jar" /><lib dir="../dist/" regex="solr-clustering-\d.*\.jar" /><lib dir="../contrib/langid/lib/" regex=".*\.jar" /><lib dir="../dist/" regex="solr-langid-\d.*\.jar" /><lib dir="../contrib/velocity/lib" regex=".*\.jar" /><lib dir="../dist/" regex="solr-velocity-\d.*\.jar" />错误处理在为pdf或者其它文件建立索引时可能会出现以下的问题，导致这些问题的主要原因也是相应的jar文件没有找到SimplePostTool: WARNING: Response: <? xml version="1.0" encoding="UTF-8"?>
