Tomcat SOLR 多核设置 [英] Tomcat SOLR multiple cores setup

问题描述

我整个上午都在尝试在 Apache Tomcat 服务器下运行的 SOLR 安装上设置多个内核，但没有成功.我的 solr.xml 看起来像这样:

I have spend all morning trying to set up multiple cores on a SOLR installation that runs under Apache Tomcat server without success. My solr.xml looks like this:

<solr persistent="false" sharedLib="lib">
  <cores adminPath="/admin/cores">
    <core name="core0" instanceDir="/multicore/core0">   
        <property name="dataDir" value="/multicore/core0/data" />
    </core>
    <core name="core1" instanceDir="/multicore/core1">
        <property name="dataDir" value="/multicore/core1/data" />
    </core>
  </cores>
</solr>

正确的目录结构是什么?我需要在 solrconfig.xml 中做一些更改吗?

What is the correct directory structure? Do I need to do change something in the solrconfig.xml?

推荐答案

检查您的 instanceDir 值是否与 -Dsolr.solr.home 相关.如果 -Dsolr.solr.home 是多核"，那么您的 instanceDir 应该只是core0".

Check that your instanceDir values are relative to -Dsolr.solr.home. If -Dsolr.solr.home is 'multicore', then your instanceDir should be only "core0".

如果将数据文件夹放在 instanceDir 中，则不必指定其路径:

If you put your data folder inside your instanceDir, you should not have to specify its path:

<?xml version='1.0' encoding='UTF-8'?>
<solr persistent="true">
<cores adminPath="/admin/cores">
    <core name="core0" instanceDir="core0" />
    <core name="core1" instanceDir="core1" />
</cores>
</solr>

您不必在 solrconfig.xml 中设置任何内容.但是，如果您需要独立于核心位置配置处理程序，则可以使用变量 ${solr.core.instanceDir}.

You should not have to set anything in solrconfig.xml. But if you need to configure an handler independantly of the core location, you can use the variable ${solr.core.instanceDir}.

更新

用Tomcat设置solr.solr.home变量，在启动Tomcat之前使用JAVA_OPTS环境变量:

To set the solr.solr.home variable with Tomcat, use the JAVA_OPTS environment variable before starting Tomcat:

JAVA_OPTS="-Dsolr.solr.home=multicore"
export JAVA_OPTS
tomcat/bin/catalina.sh start

确保相对于工作目录正确设置了多核".例如，如果 solr.solr.home='multicore'，则必须从multicore"所在的目录启动 Tomcat.

Make sure that "multicore" is correctly set relative to the working directory. Per example, if solr.solr.home='multicore', you have to launch Tomcat from the directory where "multicore" is located.
