下載軟件包：
cd /workspace/gpdb/
wget dl.#kjh#.com/greenplum-db-5.10.2-rhel7-x86_64.rpm
RPM方式，
默認安裝到 /usr/local/greenplum-db/ （以root在master執行）
rpm -Uvh greenplum-db-5.10.2-rhel7-x86_64.rpm
建立節點信任關系
打通master到各節點的免密碼登錄 （以root在master執行）
source /usr/local/greenplum-db/greenplum_path.sh gpssh-exkeys -f /workspace/gpdb/gp-all.txt
安裝各個節點，並建立gpadmin用戶（以root在master執行）
gpseginstall -f /workspace/gpdb/gp-all.txt -u gpadmin -p gpadmin安裝後檢查
source /usr/local/greenplum-db/greenplum_path.sh gpcheck -f /workspace/gpdb/gp-all.txt -m gpnode615.kjh.com gpnode616.kjh.com -s gpnode611.kjh.com gpnode612.kjh.com gpnode613.kjh.com gpnode614.kjh.com
創建服務安裝文件夾 （root用戶master節點執行）
#gpssh工具可以同時在多個機器上執行相同命令，和ansible功能類似
/usr/local/gpdata :master 數據數據目錄
/data/gpdata :sg 數據數據目錄
/data01/gpdata :sg 數據數據目錄
gpssh -f /workspace/gpdb/gp-all.txt => groupadd -g 1888 gpadmin useradd -g 1888 -u 1888 -m -d /home/gpadmin -s /bin/bash gpadmin chown -R gpadmin.gpadmin /home/gpadmin echo "gpadmin" | passwd --stdin gpadmin mkdir -p /usr/local/gpdata/gpmaster mkdir -p /data/gpdata/primary mkdir -p /data01/gpdata/primary mkdir /data/gpdata/mirror mkdir /data01/gpdata/mirror chown -R gpadmin:gpadmin /usr/local/gpdata chown -R gpadmin:gpadmin /data/gpdata chown -R gpadmin:gpadmin /data01/gpdata

修改.bashrc

cat >>/home/gpadmin/.bashrc<<-EOF
source /usr/local/greenplum-db/greenplum_path.sh
export MASTER_DATA_DIRECTORY=/usr/local/gpdata/gpmaster/gpseg-1

source /usr/local/greenplum-db/greenplum_path.sh
export MASTER_DATA_DIRECTORY=/usr/local/gpdata/gpmaster/gpseg-1
export PGPORT=5432
EOF使之生效

增加gpinitsystem_config文件為模板
cp $GPHOME/docs/cli_help/gpconfigs/gpinitsystem_config /usr/local/greenplum-db/gpinit_config
配置gpinit_config
vi /usr/local/greenplum-db/gpinit_config

gpinitsystem -c gpinit_config -h hostfile_segments
gpinitsystem命令參數解釋：
-c：指定初始化文件。
-h：指定segment主機文件。
-s：指定standby主機，創建standby節點。su - gpadmin
gpinitsystem -c /usr/local/greenplum-db/gpinit_config -h /usr/local/greenplum-db/all_segment -s gpnode616.kjh.com初始化過程：

系統登錄初始化設置：
psql修改數據庫密碼:
psql -d testgpdb
gpdb=# alter user gpadmin with password ‘gpadmin‘;
gpdb=# \q
#### 遠程登陸
psql -p 5432 -d testgpdb
# 查詢當前版本
select * from version();
設置監聽IP和Port
vi ${MASTER_DATA_DIRECTORY}/postgresql.conf
# 設置監聽IP (* 生產環境慎用)
listen_addresses = ‘${ host ip address } ‘
port = 5432
#### 設置數據庫白名單
vi ${MASTER_DATA_DIRECTORY}/pg_hba.conf
# 增加如下一條記錄，允許用戶密碼模式和可以登陸的IP地址範圍；
#TYPE DATABASE USER CIDR-ADDRESS METHOD
host all gpadmin 0.0.0.0/0 md5
# 測試登陸
psql -p 5432 -h 172.20.6.15 -U gpadmin -d testgpdb 至此集群配置完成.
