# 1. 环境

  • centos7 ip:106.15.195.75
  • docker 19.03.12
  • elasticsearch 7.8.1

# 2. 镜像

docker pull docker.elastic.co/elasticsearch/elasticsearch:7.8.1

分别给每一个 config 目录下创建一个 elasticsearch.yml 文件，进行配置。

# 6. 查看节点

curl  http://106.15.195.75:9200/_cat/nodes
106.15.195.75 43 99 0 0.00 0.04 0.08 dilmrt - es-node2
106.15.195.75 35 99 0 0.00 0.04 0.08 dilmrt * es-node1

# 7.可视化后台

然后访问http://106.15.195.75:1358/，在输入框中输入http://106.15.195.75:9200/和索引再点连接，即可进行操作了。
