greenplum數據庫安裝部署
環境以及準備工作
集群機器規劃
| 11.8.37.111 | gpmaster | 4C8G | CentOS7.4 |
| 11.8.37.112 | gpstandby | 4C8G | CentOS7.4 |
| 11.8.37.113 | segment01 | 4C8G | CentOS7.4 |
| 11.8.37.114 | segment02 | 4C8G | CentOS7.4 |
【注意】: 根據官方issue，在部署greenplum數據庫時，centos7.3版本前使用時會有一些bug問題
【注意】：如果后續需要擴容實施存儲，可以直接上更高的配置，例如8核等，根據情況自定

Spread mirroring places a given hosts mirrored segments each on a separate host. You must be adding more hosts than the number of segments per host to use this.

You must be adding at least 2 hosts in order to use this.What type of mirroring strategy would you like?spread|grouped (default=grouped): > grouped # 直接回車也可以，默認就是groupedBy default, new hosts are configured with the same number of primarysegments as existing hosts. Optionally, you can increase the numberof segments per host.For example, if existing hosts have two primary segments, entering a valueof 2 will initialize two additional segments on existing hosts, and foursegments on new hosts. In addition, mirror segments will be added forthese new primary segments if mirroring is enabled.How many new primary segments per host do you want to add?

greenplum縱向擴容實施操作
相當于集群機器保持原樣，通過更改配置，利用cpu核數增加存儲數
最后效果就是每個單機存儲節點上的seg目錄增加了
因為沒有新增服務器，所以操作基本都是在gpmaster上實施
【注意】: 縱向擴容前原來4C的配置升級到了6C
gpmaster上配置工作
