cd /root
docker run --name es1 -p 9201:9200 -p 9301:9300 -v "$PWD/node1/config/elasticsearch.yml":/usr/share/elasticsearch/config/elasticsearch.yml --ulimit nofile=65536:131072  -e "ES_JAVA_OPTS=-Xms512m -Xmx512m" -d elasticsearch


docker run --name es2 -p 9202:9200 -p 9302:9300 -v "$PWD/node2/config/elasticsearch.yml":/usr/share/elasticsearch/config/elasticsearch.yml --ulimit nofile=65536:131072 --link es1:es1  -e "ES_JAVA_OPTS=-Xms512m -Xmx512m" -d elasticsearch 

检测是否成功

docker exec -it es2 /bin/bash
curl http://localhost:9200/_cat/health
