Solr Setup - 错误:无法找到或加载主类org.apache.solr.cloud.ZkCLI

Question

我正在按照教程使用Windows 7,Java版本1.8和Solr版本4.10.2 设置Solr(http://lucene.apache.org/solr/quickstart.html).

Java安装在C:\ root\java,Solr安装在c:\ root\solr-4.10.2.

我添加了2个环境变量作为用户变量:

CLASSPATH = C:\ROOT\solr-4.10.2\dist\solr-core-4.10.2.jar
JAVA_HOME = c:\root\java

然后,我在命令提示符中运行以下代码:

cd c:\root\solr-4.10.2\bin & solr start -e cloud -noprompt

输出粘贴在下面.尽管没有添加启动核心,但集合1的Solr服务器似乎工作正常.但是,为什么ZkCLI和SolrCLI会出现错误？难道我做错了什么？

Welcome to the SolrCloud example


Starting up  Solr nodes for your example SolrCloud cluster.
Starting node1 on port 8983 using command:
solr -cloud -p 8983 -d node1

Waiting for  0 seconds, press a key to continue ...
Starting node2 on port 7574 using command:
solr -cloud -p 7574 -d node2 -z localhost:9983

Waiting for  0 seconds, press a key to continue ...

Now let's create a new collection for indexing documents in your 2-node cluster.

在不同的网站上找到它,它对我有用.

如果您在没有云选项的情况下运行solr,它会执行一些额外的操作,以使云选项工作.

所以,只是运行solr.cmd start,然后solr.cmd stop -p 8983进行准备.

然后终于跑了solr.cmd start -e cloud -noprompt.

在教程中应该注意,但Solr似乎不是Windows友好的.我认为环境变量也很重要,所以感谢您的信息.
