elasticsearch:7.12.1访问 http://192.168.137.139:9200 注意换成自己服务器的ip地址
启动kibana容器 docker run -d

kibana:7.12.1访问 http://192.168.137.139:5601 注意换成自己服务器的ip地址   给es安装 ik分词器 默认的分词器对中文并不友好ik分词器可以更好的支持中文分词 下载地址https://github.com/medcl/elasticsearch-analysis-ik/releases/tag/v7.12.1 (官方有其他的下载方式可以参考https://github.com/medcl/elasticsearch-analysis-ik) 查看es-plugins的挂载卷所在目录 docker volume inspect es-plugins得到 /var/lib/docker/volumes/es-plugins/_data 将下载的文件解压缩并传到服务器挂在卷中 scp -r ik myserver:/var/lib/docker/volumes/es-plugins/_data重启es服务 docker restart esocker logs es | grep ik # 查看ik分词器是否成功加载使用Dev Tools测试
IK分词器包含两种模式(根据业务选择) ik_smart最少切分 ik_max_word最细切分
