解压后目录如图：
solr常用命令：
solr start –p 端口号 单机版启动solr服务
solr restart –p 端口号 重启solr服务
solr stop –p 端口号关闭solr服务
solr create –c name 创建一个core实例
启动出错，解决：
我在使用启动命令时，出现错误（文末是解决方法）：

Started Solr server on port 8899. Happy searching!
PS D:\tongjiao\Solr\solr-7.4.0>原因： log4j的bug, solr.cmd 批处理没弄好；
解决办法：将solr-7.4.0/bin/solr.cmd文件里面的所有file: 改成file:/// 就可以了
