neo4j-shell 連線在 aws 上被拒絕

我已經在鏈接中檢查了關於同一問題的另一個問題

Linux 連接埠在本地開放，但不對外開放

neo4j-shell-主機127.0.0.1-埠1337

我收到錯誤

telnet 127.0.0.1 1337 正常運作 telnet 10.142.85.146 1337 失敗

我在這裡看到了一些相似之處； neo4j-shell 正在尋找 10.142.85.146 但無法找到它

我能夠使用公共IP位址正常運作；這是本地地址 我遇到了問題

任何幫助將不勝感激。我不想開始另一個問題，因此在同一個線程中編寫

其他資訊 最奇怪的部分是我的 AWS 控制台顯示私人位址是 10.142.65.14 這是如何轉換為 10.142.85.146 我不知道

答案1

我根據 AWS 命名約定使用目前 IP 和主機名稱更新了 /etc/hosts，一切都開始正常運作。

我正在查看這篇文章以在每次啟動時自動更新它們 http://www.onepwr.org/2012/04/26/chef-recipe-to-setup-up-a-new-nodes-fqdn-hostname-etc-properly/
