docker镜像搜索：
[root@master-1 ~]# docker search elasticsearch
[root@master-1 ~]# docker pull elasticsearch:7.7.0
运行docker镜像：
-p 隐射端口
-e 设置参数，discovery.type=single-node，设置单节点，ES_JAVA_OPTS="-Xms256m -Xmx256m"，设置JVM参数
-d 后台运行
--name 节点名称
[root@master-1 ~]# docker run -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" -e ES_JAVA_OPTS="-Xms256m -Xmx256m" -d --name ES01 elasticsearch:7.7.0

进入docker 容器中：
[root@master-1 ~]# docker exec -it 0bf67ecae8d0 /bin/bash
config 目录下是集群配置文件
data 目录是数据文件存储的地方
进入容器后插件安装：
[root@0bf67ecae8d0 elasticsearch]# cd plugins/
[root@0bf67ecae8d0 plugins]# elasticsearch-plugin install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v7.7.0/elasticsearch-analysis-ik-7.7.0.zip
[root@0bf67ecae8d0 plugins]# exit
[root@master-1 ~]# docker restart 0bf67ecae8d0
elasticsearch-head监控插件安装：
[root@master-1 ~]# docker pull mobz/elasticsearch-head:5
[root@master-1 ~]# docker run -d -p 9100:9100 docker.io/mobz/elasticsearch-head:5
解决跨域问题：
[root@master-1 ~]# docker exec -it 0bf67ecae8d0 /bin/bash
[root@0bf67ecae8d0 elasticsearch]# ls
LICENSE.txt NOTICE.txt README.asciidoc bin config data jdk lib logs modules plugins
[root@0bf67ecae8d0 elasticsearch]# cd config/
[root@0bf67ecae8d0 config]# ls
analysis-ik elasticsearch.keystore elasticsearch.yml jvm.options jvm.options.d log4j2.properties role_mapping.yml roles.yml users users_roles
[root@0bf67ecae8d0 config]# vi elasticsearch.yml
添加下面两句
http.cors.enabled:true
http.cors.allow-origin:"*"
保存后重启容器
[root@0bf67ecae8d0 config]# exit
exit
[root@master-1 ~]# docker restart 0bf67ecae8d0
安装kibana：
[root@master-1 ~]# docker pull kibana:7.7.0
安装完成以后需要启动kibana容器，使用--link连接到elasticsearch容器
[root@master-1 ~]# docker run --name kibana --link=ES01 -p 5601:5601 -d kibana:7.7.0
[root@master-1 ~]# docker start kibana
docker run --name elasticsearch -p 9200:9200 -p 9300:9300 \
-e "discovery.type=single-node" \
-e ES_JAVA_OPTS="-Xms256m -Xmx256m" \
--restart=always \
