命令启动  
docker run --name elasticsearch -p 9200:9200  
\-p 9300:9300  
\-e “discovery.type=single-node”  
\-e ES\_JAVA\_OPTS="-Xms64m -Xmx128m"  
\-v /mydata/elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml  
\-v /mydata/elasticsearch/data:/usr/share/elasticsearch/data  
\-v /mydata/elasticsearch/plugins:/usr/share/elasticsearch/plugins  
\-d elasticsearch:7.7.0  
参数说明  
–name elasticsearch：将容器命名为 elasticsearch  
\-p 9200:9200：将容器的9200端口映射到宿主机9200端口  
\-p 9300:9300：将容器的9300端口映射到宿主机9300端口，目的是集群互相通信  
\-e “discovery.type=single-node”：单例模式  
\-e ES\_JAVA\_OPTS="-Xms64m -Xmx128m"：配置内存大小  
\-v /mydata/elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml：将配置文件挂载到宿主机  
\-v /mydata/elasticsearch/data:/usr/share/elasticsearch/data：将数据文件夹挂载到宿主机  
\-v /mydata/elasticsearch/plugins:/usr/share/elasticsearch/plugins：将插件目录挂载到宿主机(需重启)  
\-d elasticsearch:7.7.0：后台运行容器，并返回容器ID  
docker-compose启动
