Elasticsearch
Docker部署
# 拉取镜像
docker pull elasticsearch
# 启动镜像
# "discovery.type=single-node" 标识单机启动
docker run -d --name elasticsearch -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" elasticsearch:8.2.0
# 进入docker，配置ES的各项密码
./bin/elasticsearch-setup-passwords interactiveCURD
避坑指南
- 请求的时候一定要用https协议
- 设置认证方式为Basic Auth认证，并输入用户名密码（其中默认用户名为elastic）
