《机器学习》—— SVD奇异值分解方法对图像进行压缩

参考文章：https://blog.csdn.net/Ying_ph/article/details/136586656

主要补充改动的地方

初始化ES目录：

cd /home
mkdir elasticsearch
mkdir elasticsearch/config
mkdir elasticsearch/data
mkdir elasticsearch/plugins

启动命令：

docker run -d \
	--name es \
    -e "ES_JAVA_OPTS=-Xms512m -Xmx512m" \
    -e "discovery.type=single-node" \
    -v /home/elasticsearch/data:/usr/share/elasticsearch/data \
    -v /home/elasticsearch/plugins:/usr/share/elasticsearch/plugins \
    -v /home/elasticsearch/config:/usr/share/elasticsearch/config \
    --privileged \
    --network es-net \
    -p 19200:9200 \
    -p 19300:9300 \
elasticsearch:7.12.1

启动好后安装 分词

docker exec -it es ./bin/elasticsearch-plugin  install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v7.12.1/elasticsearch-analysis-ik-7.12.1.zip

docker exec -it es ./bin/elasticsearch-plugin  install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v7.12.1/elasticsearch-analysis-ik-7.12.1.zip

引用文章里面这里安装后估计是没有映射 /home/elasticsearch/config 所以才会有些疑问

扩展分词就在/home/elasticsearch/config/analysis-ik 目录创建dic 修改IKAnalyzer.cfg.xml就好了

改完修改一下 文件权限
chmod -R 777 ext_my.dic

重启 es
