GreenPlum是一款開源的分佈式數據庫存儲解決方案，其主要關注在數據倉庫和商業智能方面。可以在虛擬化x86服務器上運行無分享（shared-nothing）的大規模並行處理（MPP）架構。
1.機器節點
192.168.12.23 mpp01
192.168.12.24 mpp02
192.168.12.25 mpp03
2.環境預備工作 （以下具體參考上篇文章）
- 關閉防火牆，關閉selinux
- 配置hosts
- 集羣間互信
- 時間同步
3.設置用戶（三臺）
groupadd -g 530 gpadmin
useradd -g 530 -u 530 -d /home/gpadmin -s /bin/bash gpadmin
chown -R gpadmin:gpadmin /usr/local
4.修改內核配置（三臺）
vim /etc/sysctl.conf
xfs_mount_options = rw,noatime,inode64,allocsize=16m
kernel.shmmax = 500000000
kernel.shmmni = 4096
kernel.shmall = 4000000000
kernel.sem = 250 512000 100 2048
kernel.sysrq = 1
kernel.core_uses_pid = 1
kernel.msgmnb = 65536
kernel.msgmax = 65536
kernel.msgmni = 2048
net.ipv4.tcp_syncookies = 1
net.ipv4.ip_forward = 0
net.ipv4.conf.default.accept_source_route = 0
net.ipv4.tcp_tw_recycle = 1
net.ipv4.tcp_max_syn_backlog = 4096
net.ipv4.conf.all.arp_filter = 1
net.ipv4.ip_local_port_range = 1025 65535
net.core.netdev_max_backlog = 10000
vm.overcommit_memory = 2
執行命令 sysctl -p 使修改數值生效
5.修改限制配置（三臺）
vim /etc/security/limits.conf
* soft nofile 65536* hard nofile 65536* soft nproc 131072* hard nproc 131072
6.設置預讀塊的值爲16384(三臺)
# /sbin/blockdev --getra /dev/sda 查看預讀塊，默認大小爲256
# /sbin/blockdev --setra 16384 /dev/sda 設置預讀塊
7.設置磁盤訪問I/O調度策略(三臺)
#echo deadline > /sys/block/sda/queue/scheduler
8.下載安裝greenplum
rpm -ivh greenplum-db-5.21.0-rhel7-x86_64.rpm
chown -R gpadmin:gpadmin /usr/local
9.創建all_hosts和all_segment文件
10.安裝檢查
切換gpadmin：su - gpadmin
source /usr/local/greenplum-db-5.21.0/greenplum_path.sh
11.設置gpadmin用戶環境變量
vim ~/.bash_profile vim ~/.bashrc
添加source /usr/local/greenplum-db-5.21.0/greenplum_path.sh
12.修改修改gpinitsystem_config文件
SEG_PREFIX=gpseg
PORT_BASE=40000
declare -a DATA_DIRECTORY=(/data1/gpdata/primary /data1/gpdata/primary)
MASTER_HOSTNAME=mpp01
MASTER_DIRECTORY=/data1/gpdata/master
MASTER_PORT=5432
TRUSTED_SHELL=ssh
CHECK_POINT_SEGMENTS=8
ENCODING=UNICODE
DATABASE_NAME=test_init_db
13.修改權限
chmod 775 gpinitsystem_config
14.分發子節點
scp -rp greenplum-db-5.21.0/ mpp02:/usr/local/
scp -rp greenplum-db-5.21.0/ mpp03:/usr/local/
15.數據庫獲取機器信任（gpadmin用戶）
- gpssh-exkeys -f /usr/local/greenplum-db-5.21.0/all_hosts
16.在主節點運行gpseginstall工具，來安裝從節點segment（gpadmin用戶）
- gpseginstall -f /usr/local/greenplum-db-5.21.0/all_segment -u gpadmin -p gpadmin
- gpssh -f /usr/local/greenplum-db-5.21.0/all_hosts -e 'mkdir -p /data1/gpdata/primary'
- gpssh -f /usr/local/greenplum-db-5.21.0/all_hosts -e 'chown gpadmin:gpadmin /data1/gpdata/primary'
- gpssh -f /usr/local/greenplum-db-5.21.0/all_segment -e 'mkdir -p /data1/gpdata/mirror'
- gpssh -f /usr/local/greenplum-db-5.21.0/all_segment -e 'chown gpadmin:gpadmin /data1/gpdata/mirror'
17.設置程序遠程訪問
- vim /data1/gpdata/master/gpseg-1/pg_hba.conf
- vim /data1/gpdata/master/gpseg-1/postgresql.conf
18.安裝子節點
- gpinitsystem -c /usr/local/greenplum-db-5.21.0/gpinitsystem_config -h /usr/local/greenplum-db-5.21.0/all_segment
19.啓動和停止數據庫測試
- $ gpstart -a
- $ gpstop -a
- $ gpstop -u //不停服務重新加載
20.進入客戶端
21.遠程機器連接客戶端
- psql -h 192.168.12.24 -p 5432 -U gpadmin -d postgres
完成安裝
select * from pg_stat_activity where DATNAME = 'struct_dev';
