解決方案：

因為安全問題elasticsearch 不讓用root使用者直接執行，所以要建立新使用者
建議建立一個單獨的使用者用來執行ElasticSearch
建立elsearch使用者組及elsearch使用者
groupadd elsearch
useradd elsearch -g elsearch -p elasticsearch

chown -R elsearch:elsearch ./elasticsearch-5.5.1 使用者目錄許可權

如果你想把 Elasticsearch 作為一個守護程序在後臺執行，那麼可以在後面新增引數 -d 。

測試 Elasticsearch 是否啟動成功，可以開啟另一個終端，執行以下操作：

curl 'http://localhost:9200/?pretty'

你應該得到和下面類似的響應(response)：

[root@localhost ~]# curl 'http://localhost:9200/?pretty'

  "name" : "SoKheeE",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "M5lU32CWQHiDEVu6XUhjeg",
