使用Solr安装liferay：启动时管理控制台无法访问+异常

标签： solr liferay

我尝试使用运行Tomcat的Liferay 5.5-5.2.3安装solr 1.4.1;我的系统是RHEL5。

下面我解释一下我遇到的错误;然后我提供了我的solr安装的详细信息。

当我启动Tomcat时，我有以下例外：

Aug 4, 2010 10:44:26 AM org.apache.solr.servlet.SolrDispatchFilter init
INFO: user.dir=/opt/apache-solr-1.4.1

Tomcat启动后，我尝试在导航器中访问solr：http://MyIpAddress/solr/。

我有“欢迎来到索尔！”页面，没关系。但是，当我点击“Solr Admin”链接时，我收到错误消息“HTTP状态404 - 路径中缺少核心名称”。

我补充说，如果我使用start.jar单独启动solr，我会得到相同的行为（我得到相同的异常，然后当我尝试访问控制台时出现相同的错误）。

现在，以下是我在安装中遵循的步骤：

  • 我下载了solr 1.4.1 ,,并在/ opt。
    • 下解压缩了该文件
  • 我在/opt/apache-solr-1.4.1/example/solr
    • 下复制了文件/opt/apache-solr-1.4.1/dist/apache-solr-1.4.1.war
  • 我创建了一个名为solr.xml的文件，其中包含以下内容，我把它放在两个文件夹中：来自Tomcat的conf / Catalina / localhost，以及/opt/apache-solr-1.4.1/example/solr：
  

上下文   的docBase = “/选择/阿帕奇-的solr-1.4.1 /示例/ solr的/阿帕奇-solr的-1.4.1.war”   debug =“0”crossContext =“true”

     

环境名称=“solr / home”   类型= “java.lang.String中”   value =“/ opt / apache-solr-1.4.1 / example / solr”override =“true”

  • 在Tomcat的文件bin / setenv.sh中，我添加了一行：

JAVA_OPTS ==“$ JAVA_OPTS -Dsolr.solr.home = SOLR_HOME / example / solr”

  • 在文件/opt/apache-solr-1.4.1/example/solr/conf/solrconfig.xml中，我在dataDir标记中显式设置索引目录：
  

$ {solr.data.dir：/opt/apache-solr-1.4.1/example/solr/data}

然后我启动了Tomcat。

感谢您对我的配置有什么问题的建议。

1 个答案:

答案 0 :(得分：0)

看起来solr.xml文件不包含正确的设置。您应该使用Catalina文件夹中的设置，但是您应该在solr主目录中创建另一个。

看起来像这样（如果你想使用核心）：

<solr persistent="false" sharedLib="./lib">
  <cores adminPath="/admin/cores">
    <core name="standards" instanceDir="standards" />
  </cores>
</solr>
