单机部署
# 下载最新的ES，https://www.elastic.co/cn/downloads/elasticsearch
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.14.0-linux-x86_64.tar.gz
tar zxvf elasticsearch-7.14.0-linux-x86_64.tar.gz -C /opt
?由于ES是不允许root用户身份启动的，所以还需要单独创建一个用户用来运行ES
adduser elastic
# 给 elastic 用户赋予权限
chown -R elastic:elastic /opt/elasticsearch-7.14.0
增加系统资源的配置
# vim /etc/security/limits.conf，重新登录账号生效
* soft nofile 65536
* hard nofile 65536
* soft nproc 4096
* hard nproc 4096
# vim /etc/sysctl.conf，执行 sysctl -p 生效
vm.max_map_count=262144
简单配置ES，config/elasticsearch.yml
# vim /opt/elasticsearch-7.14.0/config/elasticsearch.yml
network.host: 0.0.0.0
discovery.seed_hosts: ["192.168.202.133"]
cluster.initial_master_nodes: ["192.168.202.133"]
启动ES
su - elastic -C "/opt/elasticsearch-7.14.0/bin/elasticsearch"
安装head插件，见：https://github.com/mobz/elasticsearch-head
如果能翻墙，建议直接chrome扩展商店安装更方便?https://chrome.google.com/webstore/detail/elasticsearch-head/ffmkiejjmecolpfloofpjologoblkegm/related
如果不能，下载本地插件版：https://download.csdn.net/download/hjxisking/20814938
