greenplum数据库安装部署
环境以及准备工作
集群机器规划
| ip | 主机名 | 基本配置 | 操作系统 |
|---|---|---|---|
| 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】: 根据官方issue，在部署greenplum数据库时，centos7.3版本前使用时会有一些bug问题
【注意】：如果后续需要扩容实施存储，可以直接上更高的配置，例如8核等，根据情况自定
更改主机名【所有机器】
11.8.37.111 # hostnamectl set-hostname gpmaster
11.8.37.112 # hostnamectl set-hostname gpstandby

System Expansion is used to add segments to an existing GPDB array.
gpexpand did not detect a System Expansion that is in progress.
Before initiating a System Expansion, you need to provision and burn-in
the new hardware. Please be sure to run gpcheckperf to make sure the
new hardware is working properly.
Please refer to the Admin Guide for more information.
Would you like to initiate a new System Expansion Yy|Nn (default=N):
> y # yes
You must now specify a mirroring strategy for the new hosts. 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.
Grouped mirroring places all of a given hosts segments on a single
mirrored host. 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 # 直接回车也可以，默认就是grouped
By default, new hosts are configured with the same number of primary
segments as existing hosts. Optionally, you can increase the number
of segments per host.
For example, if existing hosts have two primary segments, entering a value
of 2 will initialize two additional segments on existing hosts, and four
segments on new hosts. In addition, mirror segments will be added for
these new primary segments if mirroring is enabled.
How many new primary segments per host do you want to add? (default=0):
> 0 # 直接回车也可以，默认就是0

横向扩容到这一步实施完毕。
greenplum纵向扩容实施操作
相当于集群机器保持原样，通过更改配置，利用cpu核数增加存储数
最后效果就是每个单机存储节点上的seg目录增加了
因为没有新增服务器，所以操作基本都是在gpmaster上实施
【注意】: 纵向扩容前原来4C的配置升级到了6C
gpmaster上配置工作

System Expansion is used to add segments to an existing GPDB array.
gpexpand did not detect a System Expansion that is in progress.
Before initiating a System Expansion, you need to provision and burn-in
the new hardware. Please be sure to run gpcheckperf to make sure the
new hardware is working properly.
Please refer to the Admin Guide for more information.
Would you like to initiate a new System Expansion Yy|Nn (default=N):
> y
You must now specify a mirroring strategy for the new hosts. 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.
Grouped mirroring places all of a given hosts segments on a single
mirrored host. 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
** No hostnames were given that do not already exist in the **
** array. Additional segments will be added existing hosts. **
By default, new hosts are configured with the same number of primary
segments as existing hosts. Optionally, you can increase the number
of segments per host.
For example, if existing hosts have two primary segments, entering a value
of 2 will initialize two additional segments on existing hosts, and four
segments on new hosts. In addition, mirror segments will be added for
these new primary segments if mirroring is enabled.
How many new primary segments per host do you want to add? (default=0):
> 1 # 这里多少意味着增加多少(但是需要考虑cpu核数是否支持扩容)
Enter new primary data directory 1:
> /home/gpadmin/gpdata/gpdatap3
Enter new mirror data directory 1:
