解决方案:
因为安全问题elasticsearch 不让用root用户直接运行,所以要创建新用户
建议创建一个单独的用户用来运行ElasticSearch
创建elsearch用户组及elsearch用户
groupadd elsearch
useradd elsearch -g elsearch -p elasticsearch
chown -R elsearch:elsearch ./elasticsearch-5.5.1 用户目录权限
如果你想把 Elasticsearch 作为一个守护进程在后台运行,那么可以在后面添加参数 -d 。
测试 Elasticsearch 是否启动成功,可以打开另一个终端,执行以下操作:
curl 'http://localhost:9200/?pretty'
你应该得到和下面类似的响应(response):
[root@localhost ~]# curl 'http://localhost:9200/?pretty'
