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- 解压安装介质
GP的安装包：/opt/db.zipcd /data1; unzip /opt/db.zip - 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-4.3.2.02. 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

XXXGPD10
XXXGPD11
XXXGPD12

XXXGPD06
XXXGPD07
XXXGPD08
XXXGPD09
XXXGPD10
XXXGPD11
XXXGPD12
XXXGPD13
XXXGPD143. 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" donegpssh -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 off4. 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/config5. 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.localsh bulkcp.sh /tmp/gpconfig/2rclocal.conf /tmp/gpconfig/2rclocal.confgpssh -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 $LANGen_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9:17date 060509172015hwclock -w
11. 设定网卡自启动
确定需要启用的网卡：eth2ifconfig eth2 | grep 172more /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 < 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/mirror14. 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

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-115.4 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���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
