Question

我确信主机文件中主机名（S）之前或之后没有多余的空格，使用ssh mdw可以连接到mdw。 /etc/hosts是这样的：

 127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
    ::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

错误日志：

你的绿叶中有多少台主机。您的/etc/hosts不包含有关mdw和sdw的任何信息。

假设您的greenplum中有两个名为mdw和sdw1的主机，/etc/hosts个文件应该是这样的：

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

172.31.25.24 mdw
172.31.16.170 sdw1

用您自己的名称替换ip和主机名。在再次尝试gpinitsystem之前，您需要确保已成功执行gpssh-exkeys。

<强>更新：

我使用Skype帮助他解决了这个问题。答案是他的gpadmin帐户没有权限调用ping实用程序，导致gpinitsystem调用ping以确保DBMS中的任何主机都存在。

gpinitsystem未知主机mdw
