Question

我尝试使用/opt/vertica/sbin/install_vertica脚本并按照/opt/vertica/sbin/install_vertica -s vertica001,vertica002,vertica003 -r /root/packages/vertica-6.0.1-7.x86_64.RHEL5.rpm

命令安装vertica

我收到了以下错误

我为dbadmin设置了无密码ssh，也有sudo访问权限。

我是否需要为root用户提供无密码的ssh？我在这里失踪了什么？

我是否需要为root用户提供无密码的ssh？我在这里失踪了什么？

是。安装程序在host参数中指定的节点上运行。如果节点之间没有设置SSH，那么安装程序应该如何完成该过程呢？请参阅文档中的Configuring the Network以及如何Enable Secure Shell (SSH) Logins。

问：为什么要安装Vertica 6.0？最新版本为7.2

vertica安装失败，出现ssh错误
