solr 安装（一）

pqwsa

　　首先下载tomcat和solr： 
     tomcat 7.0
     solr 3.5.0 

    使用目前网上最常见的安装方法。最初我按按照这篇文章配置的，相当简单实用。http://www.cnblogs.com/cy163/archive/2009/09/18/1569681.html

solr siki：http://wiki.chenlb.com/solr/doku.php?id=solrinstall

之后按照solrwiki上的说明，自己重新进行按照和配置，具体如下：

1. 安装tomcat，直接解压即可，我放到了c盘。

2. 解压下载的solr压缩包，将apache-solr-3.5.0\dist\apache-solr-3.5.0.war 文件复制到C:\apache-tomcat-7.0.22\webapps目录下，并重命名为solr.war 。

3. 配置tomcat。打开C:\apache-tomcat-7.0.22\conf\server.xml文件，找到port=8080那部分，加上URIEncoding="UTF-8";，这对解决solr中文问题至关重要。

<Connector port="8080" protocol="HTTP/1.1"   
connectionTimeout="20000"   
redirectPort="8443" URIEncoding="UTF-8"/>   
　　4. c盘新建一个apache-solr目录，把apache-solr-3.5.0\example\solr目录复制到该目录下，该目录将作为solr.home 。

5. 配置solr.home。在apache-tomcat-7.0.22\conf\Catalina\localhost目录先新建一个solr.xml文件。如果上述目录不存在，手动建立即可。solr.xml的内容如下： 

<Context docBase="C:/apache-tomcat-7.0.22/webapps/solr.war" reloadable="true" >
  <Environment name="solr/home" type="java.lang.String" value="C:/apache-solr/solr" override="true" />
</Context>
　　
    ok，配置结束。启动tomcat，打开 http://localhost:8080/solr/即可看到熟悉的tomcat，打开 http://localhost:8080/solr/ 即是solr的主页面。 

    实际情况是，打开http://localhost:8080/solr/ 看到的是server 500错误，相当纠结。按照之前文章的方法没有任何问题。仔细看错误信息后方法，是solr指定的包没有找到。
　　
    打开C:\apache-solr\solr\conf目下的solrconfig.xml文件，找到

<!-- A dir option by itself adds any files found in the directory to
the classpath, this is useful for including all jars in a
directory.
-->
<lib dir="../../contrib/extraction/lib" />
<lib dir="../../contrib/clustering/lib/" />
<lib dir="../../contrib/velocity/lib" />
<!-- When a regex is specified in addition to a directory, only the
files in that directory which completely match the regex
(anchored on both ends) will be included.
-->
<lib dir="../../dist/" regex="apache-solr-cell-\d.*\.jar" />
<lib dir="../../dist/" regex="apache-solr-clustering-\d.*\.jar" />
<lib dir="../../dist/" regex="apache-solr-dataimporthandler-\d.*\.jar" />
<lib dir="../../dist/" regex="apache-solr-langid-\d.*\.jar" />
<lib dir="../../dist/" regex="apache-solr-velocity-\d.*\.jar" />
<!-- If a dir option (with or without a regex) is used and nothing
is found that matches, it will be ignored
-->
<lib dir="../../contrib/clustering/lib/" />
<lib dir="/total/crap/dir/ignored" />
　　可以看到，lib引入了apache-solr-3.5.0目录下contrib和dist两个目录下的包，当使用apache-solr-3.5.0\example\solr作为solr.home时，可以正确的找到这些包。另外配置solr.home时，需要把这些文件也引入进来。把apache-solr-3.5.0目录下contrib和dist两个文件夹一起复制到C:\apache-solr目录下，然后打开C:\apache-solr\solr\conf目下的solrconfig.xml，修改如下：

<!-- A dir option by itself adds any files found in the directory to
the classpath, this is useful for including all jars in a
directory.
-->
<lib dir="../contrib/extraction/lib" />
<lib dir="../contrib/clustering/lib/" />
<lib dir="../contrib/velocity/lib" />
<!-- When a regex is specified in addition to a directory, only the
files in that directory which completely match the regex
(anchored on both ends) will be included.
-->
<lib dir="../dist/" regex="apache-solr-cell-\d.*\.jar" />
<lib dir="../dist/" regex="apache-solr-clustering-\d.*\.jar" />
<lib dir="../dist/" regex="apache-solr-dataimporthandler-\d.*\.jar" />
<lib dir="../dist/" regex="apache-solr-langid-\d.*\.jar" />
<lib dir="../dist/" regex="apache-solr-velocity-\d.*\.jar" />
<!-- If a dir option (with or without a regex) is used and nothing
is found that matches, it will be ignored
-->
<lib dir="../contrib/clustering/lib/" />
<lib dir="/total/crap/dir/ignored" />

　　ok，现在启动tomcat，打开http://localhost:8080/solr/ 即可看见solr的主页面了。
