1上传已编译完的包至/data/目录
2.解压
3 修改gpadmin的环境变量
[gpadmin@DB-01 ~]$ more .bash_profile
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
PATH=$PATH:$HOME/bin
export PATH
source /data/gpdb/greenplum_path.sh ---bin目录
export MASTER_DATA_DIRECTORY=/data/gpdb/gpdata2/gpmaster/gpseg-1 --数据目录
export PGPORT=5432
export PGDATABASE=ecejdatainfo
4 修改初始化配置文件
[gpadmin@DB-01 conf]$ pwd
/home/gpadmin/conf[gpadmin@DB-01 conf]$ ll

-rw-rw-r-- 1 gpadmin gpadmin 51 May 26 10:17 seg_hosts
[gpadmin@DB-01 conf]$ more gpinitsystem_config2 ---修改对应的数据目录 /data/gpdb/gpdata2
# FILE NAME: gpinitsystem_config
# Configuration file needed by the gpinitsystem
################################################
#### REQUIRED PARAMETERS
################################################
#### Name of this Greenplum system enclosed in quotes.
ARRAY_NAME="EMC Greenplum DW"
#### Naming convention for utility-generated data directories.
SEG_PREFIX=gpseg
#### Base number by which primary segment port numbers
#### are calculated.
PORT_BASE=40000
#### File system location(s) where primary segment data directories
#### will be created. The number of locations in the list dictate
#### the number of primary segments that will get created per
#### physical host (if multiple addresses for a host are listed in
#### the hostfile, the number of segments will be spread evenly across
#### the specified interface addresses).
declare -a DATA_DIRECTORY=(/data/gpdb/gpdata2/gpdatap1 /data/gpdb/gpdata2/gpdatap2 /data/gpdb/gpdata2/gpdatap3 /data/gpdb/gpdata2/gpdatap4)
#### OS-configured hostname or IP address of the master host.
MASTER_HOSTNAME=mdw
#### File system location where the master data directory
#### will be created.
MASTER_DIRECTORY=/data/gpdb/gpdata2/gpmaster
#### Port number for the master instance.
MASTER_PORT=5432
#### Shell utility used to connect to remote hosts.
TRUSTED_SHELL=ssh
#### Maximum log file segments between automatic WAL checkpoints.
CHECK_POINT_SEGMENTS=8
#### Default server-side character set encoding.
ENCODING=UNICODE

REPLICATION_PORT_BASE=41000
#### Base number by which mirror file replication port
#### numbers are calculated.
MIRROR_REPLICATION_PORT_BASE=51000
#### File system location(s) where mirror segment data directories
#### will be created. The number of mirror locations must equal the
#### number of primary locations as specified in the
#### DATA_DIRECTORY parameter.
declare -a MIRROR_DATA_DIRECTORY=(/data/gpdb/gpdata2/gpdatam1 /data/gpdb/gpdata2/gpdatam2 /data/gpdb/gpdata2/gpdatam3 /data/gpdb/gpdata2/gpdatam4)
################################################
#### OTHER OPTIONAL PARAMETERS
################################################
#### Create a database of this name after initialization.
#DATABASE_NAME=name_of_database
#### Specify the location of the host address file here instead of
#### with the the -h option of gpinitsystem.
MACHINE_LIST_FILE=/home/gpadmin/conf/seg_hosts
5 每个segment建立对应的节点目录
[gpadmin@DB-01 conf]$ cd /data/gpdb/gpdata2/
[gpadmin@DB-01 gpdata2]$ ll
