docker安装ES

1.下载镜像文件

docker pull elasticsearch:7.4.2 #存储和检索数据

docker pull kibana:7.4.2   #可视化检索数据

2.创建配置文件

mkdir -p /mydata/elasticsearch/config

mkdir -p /mydata/elasticsearch/data

3.创建实例

echo"http.host:0.0.0.0" >> /mydata/elasticsearch/config/elasticsearch/yml

docker run --name elasticsearch -d -e ES_JAVA_OPTS="-Xms512m -Xmx512m" -e "discovery.type=single-node" -v /mydata/myelasticsearch/plugins:/usr/share/elasticsearch/plugins \
-v /mydata/myelasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml \
-v /mydata/myelasticsearch/data:/usr/share/elasticsearch/data \
-p 9200:9200 -p 9300:9300 elasticsearch:7.4.2

一、初步索引

1、_cat

GET/_cat/nodes: 查看所有节点

GET/_cat/health:查看es健康状况

GET/_cat/master:查看主节点

GET/_cat/indices:查看所有索引 show database;

2、索引一个文档(保存)

保存一个数据，保存在哪个索引的哪个类型下，指定用哪个唯一标识 PUT custormer/external/1; 在custormer类型下保存1号数据为 PUT custormer/external/1
