7. Restart the system

8, Installation Greenplum

Installation into/opt/gpdb


sudo apt-get install-y Software-properties-common

sudo add-apt-repository ppa:greenplum/db

sudo apt-get update

sudo apt-get install-y greenplum-db-oss

9. Initializing Environment variables

$ su Root

$ source/opt/gpdb/

10. Create a host file all_hosts

$ VI all_hosts




11. Run Gpseginstall Tool

$ gpseginstall-f all_hosts-u gpadmin-p gpadmin

It's possible to avoid a secret failure.

20171215:08:55:58:054683 Gpseginstall:ifrebigdata1:root-[error]:-error on Cmd:gpssh-exkeys-f all_hosts


$su Gpadmin


$gpssh-exkeys-f all_hosts

12. Verify installation and password-free login

$ gpssh-f all_hosts-e ls $GPHOME

13. Add source/opt/gpdb/ to the. bashrc file at the end (all nodes are to be done)

14. Create a storage area

A) Create a master data storage area


b) Change of directory ownership

Chown Gpadmin/data/master

c) Create a file containing all segment hosts Seg_hosts

d) root user creates master and mirror data directories on the segment host with the Gpssh tool

$ su Root

$ source/opt/gpdb/

$ gpssh-exkeys-f all_hosts

Gpssh-f seg_hosts-e ' mkdir-p/data/primary '

Gpssh-f seg_hosts-e ' mkdir-p/data/mirror '

Gpssh-f seg_hosts-e ' Chown gpadmin/data/primary '

Gpssh-f seg_hosts-e ' Chown gpadmin/data/mirror '

15. Synchronization System Time

Installing NTP on each machine

A.gpssh-f all_hosts-e ' apt install-y ntp '

B. Modifying/etc/ntp.conf additions

Server Masterhostname

C.gpssh-f/data/all_hosts-e ' ntpd '

16. Verify Operating system settings

#gpcheck-F/data/all_hosts-m ifreBigData1

17. Initializing GP Database system


$ cp/opt/gpdb/docs/cli_help/gpconfigs/gpinitsystem_config ~/gpinitsystem_config

$ chmod 775 Gpinitsystem_config

$ VI Gpinitsystem_config

Array_name= "Greenplum Data Platform"



Declare-a data_directory= (/data/primary)








Declare-a mirror_data_directory= (/data/mirror)

A) Run the initialization tool

$ cp/data/seg_hosts ~

$ gpinitsystem-c gpinitsystem_config-h seg_hosts

Check Results

b) Setting environment variables

Add to

Export Master_data_directory=/data/master/ifreseg-1

To Master's ~/.BASHRC
