Solr 4.4.0的安装

男娘i 2022-08-06 07:07 217阅读 0赞

1.安装jdk环境（1.6及以上）及tomcat

2.下载[官网][Link 1]solr的安装包[solr-4.4.0.tgz][]并解压（此处以SOLR\_DIR表示）

3.复制SOLR\_DIR/dist/solr-4.4.0.war 到tomcat的webapps目录下（tomcat下部署项目的方式之一，这纯粹看个人喜好）并启动tomcat，此时查看tomcat的日志catalina.out 会发现报错如下

INFO: Reloading context \[/solr-4.4.0\]  
Sep 24, 2013 9:59:38 AM org.apache.catalina.core.StandardContext stop  
INFO: Container org.apache.catalina.core.ContainerBase.\[Catalina\].\[localhost\].\[/solr-4.4.0\] has not been started  
Sep 24, 2013 9:59:38 AM org.apache.catalina.core.StandardContext start  
SEVERE: Error filterStart  
Sep 24, 2013 9:59:38 AM org.apache.catalina.core.StandardContext start  
SEVERE: Context \[/solr-4.4.0\] startup failed due to previous errors

停止tomcat并移除war包（个人习惯）。

出现以上错误的原因是因为solr的war包中不包含日志的jar包，需要自己手动添加。

复制SOLR\_DIR/example/lib/ext中的jar包到tomcat的lib下，同时复制日志配置文件SOLR\_DIR/example/resources中的log4j.properties到tomcat的lib下

同时此时配置solr的home目录，打开tomcat下webapps/solr-4.4.0/WEB-INF/web.xml文件搜索entry 找到如下

并配置自己的solr/home,此处被注释，记得删除注释符。（此处以SOLR\_HOME表示）

启动tomcat，此时查看tomcat的日志catalina.out 会发现报错如下

从错误日志可以看出，缺少俩文件solr.xml及solrconfig.xml，这两个文件可以在SOLR\_DIR/example/solr及SOLR\_DIR/example/solr/collection1/conf找到。

复制solr.xml到SOLR\_HOME下，复制solrconfig.xml到SOLR\_HOME/collection1/conf下，重启tomcat，此时再查看日志，solr已正常启动

4.web查看http://localhost:8080/solr-4.4.0
