export JAVA_HOME=/usr/local/elasticsearch/jdk

修改 elasticsearch.yml

vi /usr/local/elasticsearch/config/elasticsearch.yml
cluster.name: 项目名
node.name: master
path.data: /data/elasticsearch
path.logs: /data/elasticsearch/logs

由于 elasticsearch 默认不允许 roo t 账户启动，所以要先创建一个用户

1	useradd es

创建所属组

1	chown es:es -R /usr/local/elasticsearch
