我们用的是新创建的用户，而不是root，所以文件权限不足。 ...
elasticsearch异常问题 discovery.seed_hosts, discovery.seed_providers, cluster.initial_master_nodes] must be configured
另外可以用root用户直接执行运行，不用切用户

复制下载链接后，可直接在Linux环境下载
wget https://mirrors.huaweicloud.com/elasticsearch/7.10.1/elasticsearch-7.10.1-linux-x86_64.tar.gz
解压文件
tar -zxvf elasticsearch-7.10.1-linux-x86_64.tar.gz
赋予文件夹及子文件可执行权限
chmod -R +x elasticsearch-7.10.1
创建elasticsearch启动用户：can not run elasticsearch as root
adduser es
更改文件夹（elasticsearch-7.10.1）的所属用户
chown -R es elasticsearch-7.10.1
赋予用户（es）该文件夹（elasticsearch-7.10.1）的执行权限
chmod -R +x es elasticsearch-7.10.1
切换到config目录文件
cd elasticsearch-7.10.1/config/
编辑 elasticsearch.yml
cluster.name: elasticsearch node.name: node-1
切换到bin目录文件
cd elasticsearch-7.10.1/bin/
切换用户（es），使用用户（es）后台启动elasticsearch
su es ./elasticsearch -d
访问链接，查看启动效果
curl http://localhost:9200
Ps：部署配置过程中需要注意以下几点：
1.赋予elasticsearch文件执行权限
2.创建elasticsearch启动用户，root用户不能直接启动
3.赋予elasticsearch文件用户执行权限
4.更换elasticsearch文件所属用户
5.修改elasticsearch/config/elasticsearch.yml文件中的cluster.name、node.name: node-1
6.su 切换刚创建的elasticsearch文件所属用户启动
7.elasticsearch默认访问端口为9200，若外部访问则必须开放9200映射端口
命令：/sbin/iptables -I INPUT -p tcp --dport 9200 -j ACCEPT，要在root用戶下...
