我在 Ubuntu 12.04 Tomcat6 上运行 Solr；我们升级到 16.04 和 Tomcat8，Solr 停止读取一些索引。我相信唯一受影响的索引是配置目录被软链接的索引。一些谷歌搜索后，我发现该allowLinking属性已被移动。这是我的旧配置：

<!-- /etc/tomcat6/Catalina/localhost/solr.xml -->
<Context path="/solr" docBase="/usr/share/solr"
    debug="0" privileged="true" allowLinking="true" crossContext="true">
  <Environment name="solr/home" type="java.lang.String" value="/usr/share/solr" override="true" />
</Context>

我重写为：

<!-- /etc/tomcat8/Catalina/localhost/solr.xml -->
<Context path="/solr" docBase="/usr/share/solr"                                   
    privileged="true" crossContext="true">                                         
  <Resources allowLinking="true" />      
  <Environment name="solr/home" type="java.lang.String" value="/usr/share/solr" override="true" />
</Context>

甚至在全球范围内尝试过：

<!-- /etc/tomcat8/context.xml -->
<Context>
  <WatchedResource>WEB-INF/web.xml</WatchedResource>
  <WatchedResource>${catalina.base}/conf/web.xml</WatchedResource>
  <Resources allowLinking="true"/>
</Context>

但我无法让 Solr 加载这些内核。中的错误/var/log/tomcat8/catalina.out如下：

愚蠢的问题，愚蠢的答案。

Tomcat 6 在组下运行tomcat6。Tomcat 8 以tomcat8.

我的文件是-rw-rw---- amadan:tomcat6.

解决方案：chgrp -R tomcat8 /disks/disk00/solr/。
