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

当我为 Solr创建data和data/index文件夹时，它给了我错误：collection1

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)

我在同一个字典中尝试过码头模式，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。

以下是中的消息solr.log：

有人有想法吗？谢谢

我发现问题是因为文件夹的特权。在我将所有者更改为$SOLR_HOME并且它的子目录tomcat7之后，它起作用了。

对于运行 Solr 的服务器，该文件夹必须是可写的。

所以检查/opt/solr/example/solr/collection1/。

文件夹权限并启用写入，例如：

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

引用 SOLR-3753 问题：

“在没有 solr.xml 文件的情况下，当前 4.0 的行为是使用 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 的第 94 行。 java，其中声明了默认名称“collection1”。如果没有此文档，用户可能会对“collection1”核心名称的来源感到困惑。（我就是其中之一）。

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

检查权限，确保solr主目录和子目录对tomcat7可读可写。然后在您在上面发布的 solrconfig.xml 文件中，查看以下行： <dataDir>${solr.data.dir:}</dataDir>

替换${solr.data.dir:}为您还必须创建并确保读/写权限的数据目录的路径，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，但是还有许多其他方法可以使权限工作并维护安全性。我还必须创建一个具有 tomcat7 所有权的solr.xml文件，该文件具有以下几行：/etc/tomcat7/Catalina/localhost

<?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>

同样，在 Tomcat 管理器 GUI 中停止并启动 solr。希望这可以帮助！

I used SOLR 4.7.1 deployed with spring tc server and encountered the same error. "collection1" is hard coded somewhere and it looks up for this directory and fails if it doesn't find one. To make it work I copied the "collection1" from examples directory to my solr-home and was able to bring the server up. Later I unloaded collection1, since I did not need that.

复制文件夹examples/collections的所有内容并将其移动到您的tomcat/solr。然后将文件 solr.xml 复制到您的 solr 文件夹中。重启你的tomcat7。

访问您的 solr ui，一切都应该没问题。对于在 tomcat7 下运行的 Solr 版本 4.x。
