启动Solr 8.10 后访问UI报错：CoreContainer is either not initialized or shutting down.

以cloud模式配置安装好Solr 8.10.1 启动后，在访问默认8983端口或使用solr status查看状态时报如下错误

检查基本配置如zk hosts，zk 服务启动状态发现皆没有问题，在网上找呀找据说是在solr home目录下缺失solr.xml配置文件，赶紧找一个cp过来

cp /usr/sft/solr-8.10.1/server/solr/solr.xml /usr/sft/solr-8.10.1/
cp /usr/sft/solr-8.10.1/example/files/conf/solrconfig.xml  /usr/sft/solr-8.10.1/

重启后倒是可以进心心念念的UI了，但老显示SolrCore Initialization Failures不过没有影响到目前的使用（在此用于Atlas的安装集成），先mark一下，回头来解决。
