如何创建Solr 6内核？(How to create Solr 6 cores?)

 我在Digital Ocean Ubuntu实例上安装了Solr 6： 
 
install_solr_service.sh solr-6.1.0.tgz
 
 并确认Solr正在运行。 但是，我无法通过UI或命令行创建任何内核。 我已经尝试了各种不同的排列组合： 
 
sudo ./solr create -c netest
 
 包含 
 
sudo ./solr create -c netest -d /opt/solr/server/solr/configsets/basic_configs/conf/
 
 但它总是给我： 
 
ERROR: Error CREATEing SolrCore 'netest': Unable to create core [netest] Caused by: /var/solr/data/netest/data
 
 如果我提前创建目录： 
 
sudo mkdir /var/solr/data/netest/
sudo mkdir /var/solr/data/netest/data
sudo chown -R solr:solr /var/solr/data
 
 当我重新运行创建命令时，我得到： 
 
 
 
 错误：错误创建SolrCore'netest'：无法创建核心[netest]导致：无法在类路径或'/ var / solr / data / netest'中找到资源'solrconfig.xml' 
 
 
 如果我将solrconfig.xml复制到该目录并再次运行该命令，我会得到： 
 
 
 
 错误：错误创建SolrCore'netest'：无法创建核心[netest]原因：无法在类路径或'/ var / solr / data / netest'中找到资源'schema.xml' 
 
 
 而且我陷入了这个阶段，因为谷歌没有帮我找到在哪里获取或创建schema.xml文件。 
 
 谁能帮忙？ 

I've installed Solr 6 on a Digital Ocean ubuntu instance:
 
install_solr_service.sh solr-6.1.0.tgz
 
and verified that Solr is running. However, I cannot create any cores, either through the UI or at the command line. I've tried various different permutations of:
 
sudo ./solr create -c netest
 
including
 
sudo ./solr create -c netest -d /opt/solr/server/solr/configsets/basic_configs/conf/
 
but it always gives me:
 
ERROR: Error CREATEing SolrCore 'netest': Unable to create core [netest] Caused by: /var/solr/data/netest/data
 
If I create the directory in advance:
 
sudo mkdir /var/solr/data/netest/
sudo mkdir /var/solr/data/netest/data
sudo chown -R solr:solr /var/solr/data
 
when I rerun the create command I get:
 
 
 
ERROR: Error CREATEing SolrCore 'netest': Unable to create core [netest] Caused by: Can't find resource 'solrconfig.xml' in classpath or '/var/solr/data/netest'
 
 
If I copy solrconfig.xml into the directory and run the command again I get:
 
 
 
ERROR: Error CREATEing SolrCore 'netest': Unable to create core [netest] Caused by: Can't find resource 'schema.xml' in classpath or '/var/solr/data/netest'
 
 
and I'm stuck at this stage as google isn't helping me find where to get or create the schema.xml file.
 
Can anyone help?
