我在Ubuntu 13.10中使用tomcat 7安装solr 4.5.1。
我总是遇到错误：
org.apache.solr.core.CoreContainer; Unable to create core: collection1
org.apache.solr.common.SolrException: Cannot create directory: /opt/solr/example/solr/collection1/data
当我在data为Solr创建data/index和collection1个文件夹时，它给了我错误：
org.apache.solr.common.SolrException: Lock obtain timed out: NativeFSLock@/opt/solr/example/solr/collection1/data/index/write.lock: java.io.FileNotFoundException: /opt/solr/example/solr/collection1/data/index/write.lock (Permission denied)
我在同一个词典中尝试过jetty模式，但效果很好。
以下是solrconfig.xml：
<?xml version="1.0" encoding="UTF-8" ?>
<config>
<luceneMatchVersion>4.5</luceneMatchVersion>
<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" />
<dataDir>${solr.data.dir:}</dataDir>
...
solrconfig.xml文件与solr创建的文件相同。
以下是solr.log中的消息：

有人有想法吗？感谢
我发现问题是因为文件夹的私密性。在我将$SOLR_HOME及其子字典的所有者更改为tomcat7之后，它就有用了。
答案 0 :(得分：10)
对于运行Solr的服务器，该文件夹必须是可写的。
请检查/opt/solr/example/solr/collection1/。
文件夹权限和启用写入，如：
sudo chmod a+w /opt/solr/example/solr/collection1/ -R
或更改文件夹所有者：
sudo chown tomcat7. /opt/solr/example/solr/collection1/ -R
答案 1 :(得分：3)
引用SOLR-3753问题：
＆＃34;在没有solr.xml文件的情况下，当前的4.0行为是使用CoreContainer.java中声明的默认值。这需要记录在案;可能在solr.xml和/或CoreAdmin页面上。 （参见CoreAdmin.java的第94行，其中声明了默认名称＆＃34; collection1＆＃34;如果没有此文档，用户可能会对＆＃34; collection1＆＃34;核心名称的来源感到困惑。（I＆ ＃39; m其中之一）。＆＃34;
因此，一个简单的解决方案是在$ SOLR_HOME / examples / solr /
下创建一个solr.xml文件参考 SOLR-3753
答案 2 :(得分：1)
检查权限并确保tomcat7可以读写solr主目录和子目录。然后在您上面发布的solrconfig.xml文件中，请参阅以下行：
<dataDir>${solr.data.dir:}</dataDir>
将${solr.data.dir:}替换为数据目录的路径，您还必须创建并确保读/写权限，如下所示：
<dataDir>${solr.data.dir:/home/solr/solr-4.6.0/example/solr/collection1/data}</dataDir>
然后保存，并在Tomcat管理器中重新启动solr应用程序，或者只是： #sudo service tomcat7 restart`
这些是我使用Tomcat 7和Solr 4.6设置的命令和路径，因此您的命令和路径可能会有所不同。我创建了一个solr用户并将他添加到tomcat 7组，但还有许多其他方法可以使权限工作并保持安全性。我还必须在solr.xml中使用tomcat7所有权创建一个/etc/tomcat7/Catalina/localhost文件，其中包含以下行：
<?xml version="1.0" encoding="utf-8"?>
<Context docBase="/home/solr/solr-4.6.0/dist/solr-4.6.0.war" debug="0" crossContext="true">
<Environment name="solr/home" type="java.lang.String" value="/home/solr/solr-4.6.0/example/solr" override="true"/>
</Context>

我使用了与spring tc服务器一起部署的SOLR 4.7.1并遇到了同样的错误。 ＆＃34; collection1＆＃34;在某处硬编码并查找此目录，如果找不到，则会失败。为了使它工作，我复制了＆＃34;集合1＆＃34;从examples目录到我的solr-home，能够启动服务器。后来我卸载了collection1，因为我不需要那个。

复制文件夹examples / collections的所有内容并将其移动到tomcat / solr。然后将文件solr.xml复制到solr文件夹。 重启你的tomcat7。
访问你的solr ui，一切都应该没问题。 对于在tomcat7下运行的Solr ver 4.x。
