Elasticsearch版本
rpm -ivh elasticsearch-6.8.3.rpm创立文件夹
mkdir /usr/share/elasticsearch/datamkdir /usr/share/elasticsearch/logs因为平安问题Elasticsearch不让用root用户间接运行，所以要创立新用户
创立用户命令adduser es批改用户明码passwd es将es解压目录的所有者授予此用户chown -R es:es *批改elasticsearch.yml文件

vi /etc/elasticsearch/jvm.options-Xms4g-Xmx4g批改limits.conf文件

vi /etc/sysctl.confvm.max_map_count=655360将/elasticsearch 发送给其余两个服务器hadoop2, hadoop3
scp -r /usr/local/elasticsearch hadoop2:/usr/localscp -r /usr/local/elasticsearch hadoop3:/usr/local切换至es用户并启动
su esbin/elasticsearch用浏览器拜访es所在机器的9200端口 http://hadoop1:9200
