一、环境准备

安装包：greenplum-db-6.9.0-rhel7-x86_64.rpm

下载路径：https://github.com/greenplum-db/gpdb/releases

二、基础配置

1、关闭防火墙，关闭selinux（略）

2、配置主机名

[root@gdym01-zongshuai ~]# cat  /etc/hosts
172.16.43.161 gdym01-zongshuai.novalocal

3、修改内核参数

[root@gdym01-zongshuai ~]# cat  /etc/sysctl.conf 
vm.swappiness=10
kernel.shmall = 68719476736
kernel.shmmax = 4294967296
kernel.shmmni = 4096
vm.overcommit_memory = 2 
vm.overcommit_ratio = 95 
net.ipv4.ip_local_port_range = 10000 65535 
kernel.sem = 500 2048000 200 40960
kernel.sysrq = 1
kernel.core_uses_pid = 1
kernel.msgmnb = 65536
kernel.msgmax = 65536
kernel.msgmni = 2048
net.ipv4.tcp_syncookies = 1
net.ipv4.conf.default.accept_source_route = 0
net.ipv4.tcp_max_syn_backlog = 4096
net.ipv4.conf.all.arp_filter = 1
net.core.netdev_max_backlog = 10000
net.core.rmem_max = 2097152
net.core.wmem_max = 2097152
vm.zone_reclaim_mode = 0
vm.dirty_expire_centisecs = 500
vm.dirty_writeback_centisecs = 100
vm.dirty_background_ratio = 3
vm.dirty_ratio = 10
vm.dirty_background_bytes = 1610612736
vm.dirty_bytes = 4294967296

4、修改描述符文件

[root@gdym01-zongshuai ~]# cat  /etc/security/limits.conf 
* soft nofile 65536
* hard nofile 65536
* soft nproc 131072
* hard nproc 131072

三、安装greenplum数据库

1、rpm安装

[root@gdym01-zongshuai ~]#rpm -ivh --prefix=/data/greenplum  greenplum-db-6.9.0-rhel7-x86_64.rpm

2、创建gpadmin用户并授权

[root@gdym01-zongshuai greenplum]# groupadd -g 530 gpadmin
[root@gdym01-zongshuai greenplum]# useradd -g 530 -u 530 -m -d /home/gpadmin -s /bin/bash gpadmin
[root@gdym01-zongshuai greenplum]# chown -R gpadmin:gpadmin /data/greenplum

3、应用环境变量

切换gpadmin用户

[root@gdym01-zongshuai greenplum]# su - gpadmin
[gpadmin@gdym01-zongshuai ~]$ source   /data/greenplum/greenplum-db/greenplum_path.sh

4、 设置gpadmin用户的环境变量

[gpadmin@gdym01-zongshuai ~]$ cat ~/.bash_profile 
export MASTER_DATA_DIRECTORY=/data/greenplum/gpdata/master/gpseg-1
export PGPORT=5432
export PGUSER=gpadmin
export PGDATABASE=gpdb
[gpadmin@gdym01-zongshuai ~]$ source  ~/.bash_profile 

5、配置免密

[gpadmin@gdym01-zongshuai ~]$ ssh-keygen  -t rsa
[gpadmin@gdym01-zongshuai ~]$ ssh-copy-id gdym01-zongshuai.novalocal

7、添加节点服务器文件

[gpadmin@gdym01-zongshuai ~]$ vim  seg_hosts 
gdym01-zongshuai.novalocal

8、使用gpssh-exkeys打通所有服务器(Master)

[gpadmin@gdym01-zongshuai ~]$ gpssh-exkeys -f /home/gpadmin/seg_hosts

9、创建数据目录

[gpadmin@gdym01-zongshuai greenplum]$ mkdir -p /data/greenplum/gpdata/master
[gpadmin@gdym01-zongshuai greenplum]$ mkdir -p /data/greenplum/gpdata/primary
[gpadmin@gdym01-zongshuai greenplum]$ mkdir -p /data/greenplum/gpdata/mirror 

四、初始化数据库

1、复制配置文件

[gpadmin@gdym01-zongshuai ~]$ cp  /data/greenplum/greenplum-db/docs/cli_help/gpconfigs/gpinitsystem_config   /home/gpadmin/initGreenplum

2、修改配置文件 /home/gpadmin/initGreenplum

declare -a DATA_DIRECTORY=(/data/greenplum/gpdata/primary)
MASTER_HOSTNAME=172.16.43.161
MASTER_DIRECTORY=/data/greenplum/gpdata/master
MASTER_PORT=5432 
MIRROR_PORT_BASE=7000 
DATABASE_NAME=gpdb 
declare -a MIRROR_DATA_DIRECTORY=(/data/greenplum/gpdata/mirror) 
MACHINE_LIST_FILE=/home/gpadmin/seg_hosts

3、运行初始化命令

 [gpadmin@gdym01-zongshuai ~]$ gpinitsystem -c /home/gpadmin/initGreenplum

 4、连接greenplum

先给gpadmin创建密码

alter role gpadmin with password 'gpadmin';

 五、允许远程登陆

1、修改pg_hba.conf文件

[gpadmin@gdym01-zongshuai gpseg-1]$ pwd
/data/greenplum/gpdata/master/gpseg-1
[gpadmin@gdym01-zongshuai gpseg-1]$ vim  pg_hba.conf 
host     all         gpadmin     172.16.0.0/16   trust

2、重新加载配置

[gpadmin@gdym01-zongshuai gpseg-1]$ pg_ctl reload -D  /data/greenplum/gpdata/master/gpseg-1/
