硬件配置：
16 台 IBM X3650,
节点配置：CPU 2 * 8core，内存 128GB，硬盘 16 * 900GB，万兆网卡。
万兆交换机。

安装需求：
1台Master，1台Standby Master，14台Segment计算节点。

安装步骤：
1. Master节点安装
2. 创建GP安装配置文件并配置ssh互信
3. 关闭防火墙及开启自启动
4. 关闭SELinux
5. 磁盘调度算法
6. 磁盘预读取配置
7. 语言与字符集
8. Sysctl.conf增加配置
9. 用户资源限额配置
10. 时间校对
11. 设定网卡自启动
12. 创建用户(可选)
13. 创建目录并赋权
14. 各节点GP软件的安装
15. 初始化GP数据库

1. Master节点安装

先确认各节点目录结构保持一致：

[root@XXXGPM01 db]# df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/sda6        20G  440M   18G   3% /
tmpfs            63G   76K   63G   1% /dev/shm
/dev/sda2       485M   39M  421M   9% /boot
/dev/sda1       200M  260K  200M   1% /boot/efi
/dev/sda4       5.5T  3.1G  5.5T   1% /data1
/dev/sdb1       5.8T   34M  5.8T   1% /data2
/dev/sda8       9.7G  150M  9.0G   2% /home
/dev/sda5        49G  3.1G   43G   7% /opt
/dev/sda9       9.7G  151M  9.0G   2% /tmp
/dev/sda7        20G  5.8G   13G  32% /usr
/dev/sda10      9.7G  338M  8.8G   4% /var

主节点/etc/hosts文件，追加内容（万兆网卡的IP地址和主机名）：

172.16.99.18 XXXGPM01
172.16.99.19 XXXGPM02
172.16.99.20 XXXGPD01
172.16.99.21 XXXGPD02
172.16.99.22 XXXGPD03
172.16.99.23 XXXGPD04
172.16.99.24 XXXGPD05
172.16.99.25 XXXGPD06
172.16.99.26 XXXGPD07
172.16.99.27 XXXGPD08
172.16.99.28 XXXGPD09
172.16.99.29 XXXGPD10
172.16.99.30 XXXGPD11
172.16.99.31 XXXGPD12
172.16.99.32 XXXGPD13
172.16.99.33 XXXGPD14
  1. 解压安装介质
    GP的安装包：/opt/db.zip
    cd /data1; unzip /opt/db.zip
  2. 安装目录
    mkdir -p /data1/gpinstall

在 XXXGPM1 节点上，将 greenplum-db-4.x.x.x-build-5-RHEL5-x86_64.zip 解开， 以 root 用户执行得到的.bin 文件。按照提示进行安装。

# /bin/bash greenplum-db-4.3.2.0-build-1-RHEL5-x86_64.bin

选择自定义安装目录： /data1/gpinstall/greenplum-db-4.3.2.0

安装完成之后，可以看到如下目录

[root@XXXGPM01 gpinstall]# pwd
/data1/gpinstall
[root@XXXGPM01 gpinstall]# ls -lh
总用量 4.0K
lrwxrwxrwx.  1 root root   22 6月   4 18:51 greenplum-db -> ./greenplum-db-4.3.2.0
drwxr-xr-x. 11 root root 4.0K 6月   4 18:51 greenplum-db-4.3.2.0

2. 创建GP安装配置文件并配置ssh互信

mkdir -p /data1/gpinstall/config
创建两个配置文件

1. allnodes.txt

XXXGPM01
XXXGPM02
XXXGPD01
XXXGPD02
XXXGPD03
XXXGPD04
XXXGPD05
XXXGPD06
XXXGPD07
XXXGPD08
XXXGPD09
XXXGPD10
XXXGPD11
XXXGPD12
XXXGPD13
XXXGPD14

2. nodes.txt

XXXGPD01
XXXGPD02
XXXGPD03
XXXGPD04
XXXGPD05
XXXGPD06
XXXGPD07
XXXGPD08
XXXGPD09
XXXGPD10
XXXGPD11
XXXGPD12
XXXGPD13
XXXGPD14

3. 配置所有GP节点root用户的ssh互信：

source /data1/gpinstall/greenplum-db/greenplum_path.sh 
gpssh-exkeys -f /data1/gpinstall/config/allnodes.txt

测试可以正常互信。此时就可以方便的去同步配置所有的参数。

先写脚本同步各节点的/etc/hosts文件：

#!/bin/bash
#Usage: copy files to other hosts in cluster.
#ex: sh bulkcp.sh /etc/hosts /etc/hosts
#Author: AlfredZhao
#Version: 1.0.0
for((i=18;i<=33;i++))
do
 scp $1 172.16.99.$i:$2
 echo "scp $1 172.16.99.$i:$2"
done

gpssh -f /data1/gpinstall/config/allnodes.txt -e ” 回车即可进入交互性界面。

3. 关闭防火墙及开启自启动

检查是否关闭及开机启动项设置：

service iptables status
service ip6tables status
service libvirtd status

service iptables stop
service ip6tables stop
service libvirtd stop

chkconfig libvirtd off
chkconfig iptables off
chkconfig ip6tables off

4. 关闭SELinux

检查SELinux的当前状态和配置：

getenforce
more /etc/selinux/config | grep SELINUX=

临时关闭SELinux和永久禁用SELinux：

setenforce 0
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config

5. 磁盘调度算法

检查当前的磁盘调度算法：
cat /sys/block/sd*/queue/scheduler

原厂给的设置方法：
修改/boot/grub/menu.lst 找到 kernel /vmlinuz-xxx 这一行，在最后添加 elevator=deadline

检查/验证方法：
系统启动正常后，执行 cat /sys/block/*/queue/scheduler 应能看到： noop anticipatory [deadline] cfq

实际遇到问题：RHEL6.5系统 没有/boot/grub/menu.lst 这个文件。
nl /boot/grub/menu.lst
换一个思路，利用rc.local配置加两行信息如下：

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

这里为了快速同步集群的配置统一，将这两行写入临时配置文件/tmp/gpconfig/1deadline.conf,然后同步到各节点。
mkdir -p /tmp/gpconfig
最后在交互性界面执行命令：
cat /tmp/gpconfig/1deadline.conf >> /etc/rc.d/rc.local

6. 磁盘预读取配置

检查磁盘预读取设置，应都是 16384：
blockdev –getra /dev/sd* blockdev –getra /dev/dm-*

设置办法：
修改/etc/rc.d/rc.local 增加两行

blockdev --setra 16384 /dev/sd* 
blockdev --setra 16384 /dev/dm-*

检查办法：
系统重启后，运行
blockdev --getra /dev/sd* blockdev --getra /dev/dm-* 应都是 16384

/etc/rc.d/rc.local
sh bulkcp.sh /tmp/gpconfig/2rclocal.conf /tmp/gpconfig/2rclocal.conf
gpssh -f /data1/gpinstall/config/allnodes.txt -e ''
cat /tmp/gpconfig/2rclocal.conf >> /etc/rc.d/rc.local

7. 语言与字符集

检查语言和字符集：echo $LANG
en_US.UTF-8
设置办法：系统安装时指定。
检查办法：登录系统，执行命令 locale 结果应该是 en_US.UTF-8

修改：
sed -i 's/zh_CN.UTF-8/en_US.UTF-8/g' /etc/sysconfig/i18n

8. Sysctl.conf增加配置

配置sysctl.conf
sysctl -p
有时需要 modprobe bridge

设置办法： 修改/etc/sysctl.conf,
增加以下内容：

net.ipv4.ip_forward = 0  
net.ipv4.conf.default.accept_source_route = 0  
kernel.sysrq = 0  
kernel.core_uses_pid = 1  
net.ipv4.tcp_syncookies = 1  
kernel.msgmnb = 65536  
kernel.msgmax = 65536  
kernel.sem = 250 64000 100 2048  
kernel.shmmax = 5000000000  
kernel.shmmni = 40960  
kernel.shmall = 40000000000  
net.ipv4.tcp_tw_recycle=1  
net.ipv4.tcp_max_syn_backlog=4096  
net.core.netdev_max_backlog=10000  
vm.overcommit_memory=2  
net.ipv4.conf.all.arp_filter = 1  
net.ipv4.ip_local_port_range = 1025 65535

然后执行 sysctl -p。

vi /tmp/gpconfig/4sysctl.conf
sh bulckcp.sh /tmp/gpconfig/4sysctl.conf /tmp/gpconfig/4sysctl.conf
gpssh -f /data1/gpinstall/config/allnodes.txt -e ''
cat /tmp/gpconfig/4sysctl.conf >> /etc/sysctl.conf

检查办法： 用 sysctl ，检查上述各参数是否匹配。

9. 用户资源限额配置

查看用户资源限额：
ulimit -a

设置办法：
修改 /etc/security/limits.d/90-nproc.conf
Replace with：

* soft nofile 1048576 
* hard nofile 1048576 
* soft nproc 1048576 
* hard nproc 1048576

同步修改：

vi /tmp/gpconfig/5limits.conf
sh bulkcp.sh /tmp/gpconfig/5limits.conf /tmp/gpconfig/5limits.conf
nl /etc/security/limits.d/90-nproc.conf
cat /tmp/gpconfig/5limits.conf >> /etc/security/limits.d/90-nproc.conf

检查办法： 用任意普通用户登录，执行 ulimit -a，检查上述参数是否匹配。

10. 时间校对

检查时间：
date

校对时间：
–2015年6月5日9:17
date 060509172015
hwclock -w

11. 设定网卡自启动

确定需要启用的网卡：eth2
ifconfig eth2 | grep 172
more /etc/sysconfig/network-scripts/ifcfg-eth2 |grep ONBOOT

修改eth2网卡配置，开启自启动
sed -i 's/ONBOOT=no/ONBOOT=yes/g' /etc/sysconfig/network-scripts/ifcfg-eth2

以上步骤修改完毕后统一重启下机器，再次验证以上各个步骤是否修改成功。

12. 创建用户(可选)

这个也可以在gpseginstall时指定选项创建，这里为了规范业务用户的uid和gid事先先创建好组和用户：
写一个小脚本，分发到各节点，然后在交互式界面下统一执行脚本建立组，用户，密码：

#!/bin/bash
#Usage: create gpadmin
#Author: AlfredZhao
#version: 1.0.0

groupadd gpadmin -g 3030
useradd gpadmin -u 3030 -g 3030
passwd gpadmin <<EOF
> gpadminpwd
> gpadminpwd
> EOF

13. 创建目录并赋权

Master 目录：

gpssh -h XXXGPM01 -e 'mkdir -p /data1/master' 
gpssh -h XXXGPM02 -e 'mkdir -p /data1/master'

gpssh -h XXXGPM01 -e 'chown gpadmin:gpadmin /data1/master' 
gpssh -h XXXGPM02 -e 'chown gpadmin:gpadmin /data1/master'

数据库数据文件存储目录：
注意这里配置文件变为nodes.txt,主节点并不需要创建这些目录。

gpssh -f /data1/gpinstall/config/nodes.txt -e ''

mkdir -p /data1/primary 
mkdir -p /data1/mirror     
mkdir -p /data2/primary 
mkdir -p /data2/mirror

chown gpadmin:gpadmin /data1/primary 
chown gpadmin:gpadmin /data1/mirror     
chown gpadmin:gpadmin /data2/primary 
chown gpadmin:gpadmin /data2/mirror

14. 各节点GP软件的安装

gpseginstall -f allnodes.txt -c csv
如果前面没有手工提前建立gpadmin用户，这里可以指定用户密码(-u -p)，统一建立gpadmin用户和密码

[root@XXXGPM01 data1]# gpseginstall -f /data1/gpinstall/config/allnodes.txt -c csv

15. 初始化GP数据库

以下工作，在Master节点上以gpadmin用户登陆完成。
cd /data1/gpinstall/config
新建gpinitsystem_config配置文件，内容如下：

ARRAY_NAME="XXXGPDB"  
SEG_PREFIX=gpseg  
PORT_BASE=40000  
declare -a DATA_DIRECTORY=(/data1/primary /data1/primary /data1/primary /data1/primary /data1/primary /data1/primary /data2/primary /data2/primary /data2/primary /data2/primary /data2/primary /data2/primary)  
MASTER_HOSTNAME=XXXGPM01 
MASTER_DIRECTORY=/data1/master  
MASTER_PORT=5432  
TRUSTED_SHELL=ssh 
CHECK_POINT_SEGMENTS=256 
ENCODING=UNICODE 
MIRROR_PORT_BASE=50000  
REPLICATION_PORT_BASE=41000  
MIRROR_REPLICATION_PORT_BASE=51000  
declare -a MIRROR_DATA_DIRECTORY=(/data1/mirror /data1/mirror /data1/mirror /data1/mirror /data1/mirror /data1/mirror /data2/mirror /data2/mirror /data2/mirror /data2/mirror /data2/mirror /data2/mirror)

15.1 配置下gpadmin用户的各节点间互信：

gpssh-exkeys -f /data1/gpinstall/config/allnodes.txt

15.2 初始化数据库：

gpinitsystem -c gpinitsystem_config -h nodes.txt -B 8

15.3 配置环境变量：

source /usr/local/greenplum-db/greenplum_path.sh
export MASTER_DATA_DIRECTORY=/data1/master/gpseg-1

15.4 建立冗余的master节点：

gpinitstandby -s XXXGPM02

15.5 调整数据库参数：

以下数据库参数调整后必须重新启动数据库。

调整方法：执行命令 gpconfig -c 参数名 -v 参数值 -m Master节点值

检查方法：重启数据库后，执行命令 gpconfig -s 参数名

参数名 参数值 master节点值

gpconfig -c shared_buffers -v 128MB -m 128MB
gpconfig -c gp_vmem_protect_limit -v 15360 -m 15360
gpconfig -c max_connections -v 1000 -m 200
gpconfig --skipvalidation -c wal_send_client_timeout -v 60s -m 60s

15.9 创建业务数据库XXX

项目内规范：所有后期创建数据库，都必须在psql 登陆到postgres数据库后创建！！

psql postgres
postgres=# create database XXX;
CREATE DATABASE

psql XXX

15.10 调整连接控制参数

修改文件 $MASTER_DATA_DIRECTORY/pg_hba.conf
增加一行：
host all all 0/0 md5
修改standby master上的文件 $MASTER_DATA_DIRECTORY/pg_hba.conf
增加一行：
host all all 0/0 md5
