Ubuntu下安装Solr4.4

操作环境: Win8 / Ubuntu64（最下面）, Tomcat7, Solr4.4, Jdk7

En More : http://wiki.apache.org/solr/SolrTomcat 

1) 在apache官网下载solr4.4的包，解压到本地目录，如E:\apache\solr-4.4.0

2) 找一个目录作为solr的home目录，如D:/WebContainer/apache-solr-home

3) 解压tomcat7，到bin先运行startup.bat，确保tomcat正常运行和访问，关闭tomcat

4) 复制E:\apache\solr-4.4.0\example\solr目录下的所有文件到D:/WebContainer/apache-solr-home

5) 复制E:\apache\solr-4.4.0\dist目录下solr-4.4.0.war包到D:/WebContainer/apache-solr-home,再对solr-4.4.0.war解压solr-4.4.0, 重命名solr-4.4.0为solr.

6) 在tomcat\conf\Catalina\localhost目录下新增solr.xml，内容如下：

<?xml version="1.0" encoding="UTF-8"?>
<Context docBase="D:/WebContainer/apache-solr-home/solr" debug="0" crossContext="true">
    <Environment name="solr/home" type="java.lang.String" value="D:/WebContainer/apache-solr-home" override="true" />
</Context>

7)  把solr-4.4.0\example\lib\ext下的lib包全部复制到tomcat\lib下

8)  启动tomcat，访问http://localhost:8080/solr/

在配置的过程中, 发生一些错误. 

solr - org.apache.solr.common.SolrException: Could not load config for solrconfig.xml

在这里再添加一步, 在solr\WEB-INF\web.xml修改

去掉注释: 

<!--
<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>
-->

 修改为:

<env-entry>
   <env-entry-name>solr/home</env-entry-name>
   <env-entry-value>D:/WebContainer/apache-solr-home/solr</env-entry-value>
   <env-entry-type>java.lang.String</env-entry-type>
</env-entry>

 9)  再重启Tomcat. http://localhost:8080/solr/

在ubuntu下面安装Solr 4.4 请参见比较新的一篇文章：

 发现找不到solrconfig.xml文件 拷贝solr-4.4.0/example/solr下的所有文件至/home/web/solr-env/ 下面。重启Tomcat解决问题。
