安裝介質：
greenplum-db-5.17.0-rhel6-x86_64.zip
地址：
https://network.pivotal.io/products/pivotal-gpdb#/releases/301769/file_groups/1397
有二進制安裝包和RPM安裝包，我這里選擇二進制安裝包來安裝

機器規劃（一個主節點，三個數據節點）：
192.168.11.210 mdw
192.168.11.211 sdw1
192.168.11.212 sdw2
192.168.11.213 sdw3

1，禁用防火墻和selinux

service iptables stop chkconfig iptables offvi /etc/selinux/config selinux=disabled

2，配置內核參數
配置內核參數文件：

vi /etc/sysctl.confkernel.shmmax = 500000000 kernel.shmmni = 4096 kernel.shmall = 4000000000 kernel.sem = 500 1024000 200 4096 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_tw_recycle = 1 net.ipv4.tcp_max_syn_backlog = 4096 net.ipv4.conf.all.arp_filter = 1 net.ipv4.ip_local_port_range = 10000 65535 net.core.netdev_max_backlog = 10000 net.core.rmem_max = 2097152 net.core.wmem_max = 2097152 vm.overcommit_memory = 2 vm.swappiness = 10 vm.dirty_expire_centisecs = 500 vm.dirty_writeback_centisecs = 100 vm.dirty_background_ratio = 0 vm.dirty_ratio=0 vm.dirty_background_bytes = 1610612736 vm.dirty_bytes = 4294967296

執行sysctl -p使內核參數生效

3，配置資源限制參數

vi /etc/security/limits.conf * soft nofile 65536 * hard nofile 65536 * soft nproc 131072 * hard nproc 131072

4，文件系統格式
文件系統格式推薦使用XFS

5，配置磁盤文件預讀參數
推薦配置為16384
獲取當前值：/sbin/blockdev --getra /dev/sda
設置新值：/sbin/blockdev --setra 16384 /dev/sda

6，配置磁盤I/O調度策略
推薦設置成deadline模式，有兩種設置方法
方法一：

echo deadline /sys/block/sda/queue/scheduler

重啟之后失效，可以把上面命令配置到環境變量或者rc.local里面使之啟動生效

方法二（永久）：
在grub.conf里面配置elevator=deadline：

vi /etc/grub.conf kernel /vmlinuz-2.6.32-754.11.1.el6.x86_64 ro root=UUID=39773d5f-aa30-4e9c-aca4-b8f41a865397 elevator=deadline rd_NO _LUKS rd_NO_LVM LANG=en_US.UTF-8 rd_NO_MD SYSFONT=latarcyrheb-sun16 crashkernel=auto KEYBOARDTYPE=pc KEYTABLE=us rd_NO_DM r hgb quiet

7，禁用THP（透明大頁）
grub.conf里面添加transparent_hugepage=never：

vi /etc/grub.conf kernel /vmlinuz-2.6.32-754.11.1.el6.x86_64 ro root=UUID=707d5027-2cc0-4111-9efc-bddc1cc4fe5d elevator=deadline rd_NO _LUKS rd_NO_LVM LANG=en_US.UTF-8 rd_NO_MD SYSFONT=latarcyrheb-sun16 crashkernel=auto KEYBOARDTYPE=pc KEYTABLE=us rd_NO_DM r hgb quiet transparent_hugepage=never

需要重啟生效

8，創建用戶和組

groupadd gpadmin useradd gpadmin -g gpadmin New password: <changeme> Retype new password: <changeme>

9，安裝GPDB

unzip greenplum-db-5.17.0-rhel6-x86_64.zip ./greenplum-db-5.17.0-rhel6-x86_64.bin

交互模式中需要接受license，設置安裝路徑等，本文安裝路徑為/home/gpadmin/greenplum

10，創建hostlist文件
創建兩個hostlist文件，列出各個節點的主機名（host列出所有機器主機名，seg_host僅列出segment主機名）

vi host mdw sdw1 sdw2 sdw3vi seg_host sdw1 sdw2 sdw3

11，配置各個節點互信

gpssh-exkeys -f /home/gpadmin/greenplum/host

12，其它節點批量安裝GPDB

gpseginstall -f /home/gpadmin/greenplum/host

–確認其他節點安裝情況

gpssh -f /home/gpadmin/greenplum/host -e ls -l $GPHOME

13，創建數據存儲目錄
主節點創建數據目錄：

mkdir -p /home/gpadmin/gpdata/master

segment節點批量創建目錄

gpssh -f seg_host -e 'mkdir -p /home/gpadmin/gpdata/primary' gpssh -f seg_host -e 'mkdir -p /home/gpadmin/gpdata/mirror'

由于本文是直接安裝在家目錄下面，不會涉及權限問題，如果安裝其它目錄下需要配置相應權限

14，配置NTP同步
略

15，配置初始化gpdb參數
復制初始化參數文件到gpdb安裝目錄

cp /home/gpadmin/greenplum/docs/cli_help/gpconfigs/gpinitsystem_config /home/gpadmin/greenplum

修改gpdb初始化參數文件

vi gpinitsystem_config ARRAY_NAME="Greenplum Data Platform" SEG_PREFIX=gpseg PORT_BASE=6000 declare -a DATA_DIRECTORY=(/home/gpadmin/gpdata/primary /home/gpadmin/gpdata/primary /home/gpadmin/gpdata/primary) MASTER_HOSTNAME=mdw MASTER_DIRECTORY=/home/gpadmin/gpdata/master MASTER_PORT=5432 TRUSTED_SHELL=ssh CHECK_POINT_SEGMENTS=8 ENCODING=UNICODE MIRROR_PORT_BASE=7000 REPLICATION_PORT_BASE=8000 MIRROR_REPLICATION_PORT_BASE=9000 declare -a MIRROR_DATA_DIRECTORY=(/home/gpadmin/gpdata/mirror /home/gpadmin/gpdata/mirror /home/gpadmin/gpdata/mirror) DATABASE_NAME=devin MACHINE_LIST_FILE=/home/gpadmin/greenplum/seg_host

15，初始化gpdb

gpinitsystem -c gpinitsystem_config -h seg_host

其他常用參數
-s 配置standby master
-S spread mirror （默認grouped mirror模式）

16，檢查gpdb狀態
