我为 dbadmin 设置了无密码 ssh，它也有 sudo 访问权限。

我需要为 root 用户设置无密码 ssh 吗？我在这里缺少什么？

Answer 1

Do I need to have passwordless ssh for root user here ? what I am missing here ?

是的。安装程序在主机参数中指定的节点上运行。如果未在节点之间设置 SSH，安装程序还应该如何完成该过程？参见 Configuring the Network以及如何Enable Secure Shell (SSH) Logins在文档中。

问:为什么要安装 Vertica 6.0？最新版本是7.2
