1.拉取镜像

代码语言：javascript复制
docker pull elasticsearch:7.7.0

2.创建挂载卷

代码语言：javascript复制
#创建目录
mkdir -p /docker/ES
mkdir /docker/ES/data1
mkdir /docker/ES/data2
mkdir /docker/ES/data3
mkdir /docker/ES/data4
mkdir /docker/ES/data5
mkdir /docker/ES/config
cd /docker/ES
chmod 777 data1 data2 data3 data4 data5
cd /docker/ES/config
#创建文件
touch es1.yml es2.yml es3.yml es4.yml es5.yml

3.编写es的yml配置文件

注意：云服务器需要设置安全策略放行9200,9300,9301,9302,9303,9304端口，否则访问失败;

注意：discovery.seed_hosts配置的是集群服务器，部署几台就写几台，集群最低3台，否则需要修改discovery.zen.minimum_master_nodes为1；

注意：124.71.65.69地址需要换成自己的服务器ip
