运行 gpccinstall 时安装 greenplum 命令中心失败

Question

我用 5.18 为我的 greenplum db 下载了 greenplum-cc-web-4.6.1-LINUX-x86_64.zip，然后点击此链接 (https://gpcc.docs.pivotal.io/460/topics/setup-collection-agents.html) 安装命令中心。当 gpccinstall 出现故障时，一切正常。它显示以下错误：

RunCommandOnEachHost failure happened

以前有没有人遇到过这个问题？我在谷歌和关键社区中进行了一些搜索，但未能找到解决方案。任何帮助表示赞赏。

顺便说一句，当我忽略上述错误并继续时，我发现 gpcc Web 服务器可以成功启动。当我登录时，只有“查询监视器”UI 部分显示一个警告：“GPCC 不再接收更新。检查您的网络状态或 gpcc 状态并刷新此页面。”，其他部分 UI 似乎正常。

Answer 1

从这里开始：

Error when unzip remote binary on client-gp03.bj Warning: the ECDSA host key for 'client-gp03.bj' differs from the key for the IP address '10.136.173.8'
Offending key for IP in /home/gpadmin/.ssh/known_hosts:10
Matching host key in /home/gpadmin/.ssh/known_hosts:17
tar: bin/gpccws: Cannot open: File exists
tar: Exiting with failure status due to previous errors

您的 /home/gpadmin/.ssh/known_hosts 文件中有重复的 ssh 指纹密钥。我建议从该文件中删除第 10 行和第 17 行，然后运行 ​​ssh-keyscan client-gp03.bj >> /home/gpadmin/.ssh/known_hosts

完成后，尝试ssh-ing到主机，看看指纹错误是否清除，如果是，再次尝试gpcc安装。
