安装ifconfig（如果已经安装，可以跳过）
```
yum install net-tools.x86_64
```
设置静态IP（防止重启后DHCP分配新的IP）

安装Greenplum

上传文件到master（mdw）主机

rz（可以使用其它方式上传）
```
yum install lrzsz.x86_64
```

mkdir /root/appcd /root/app
rz#从虚拟机host上选择greenplum-db-4.3.8.0-build-1-RHEL5-x86_64.bin进行上传,也可使用wget进行下载

wget（省略）

GP binary安装master（mdw）

/bin/bash greenplum-db-4.3.8.0-build-1-RHEL5-x86_64.bin

q #略过
Do you accept the Pivotal Database license agreement? [yes|no] yes
<Enter> #默认路径安装
Install Greenplum Database into </usr/local/greenplum-db-4.3.8.0>? [yes|no] yes
/usr/local/greenplum-db-4.3.8.0 does not exist.
Create /usr/local/greenplum-db-4.3.8.0 ? [yes|no]
(Selecting no will exit the installer) yes

创建服务器列表master（mdw）

创建host_file，包含了Greenplum部署的所有主机名，内容如下：
mdw
smdw
sdw1
sdw2
sdw3

创建一个hostfile_segonly，包含了所有的Segment Host的主机名，内容如下：
sdw1
sdw2
sdw3

创建hostfile_exkeys，包含了所有的Greenplum主机的网口对应的主机名（因为有可能是双网卡的服务器），内如如下：
mdw
smdw
sdw1
sdw2
sdw3

设置ssh免密码登陆master（mdw）
```
ssh-keygen -t rsa
```

cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

chmod 600 ~/.ssh/authorized_keys

#copy到所有服务器上

scp ~/.ssh/authorized_keys root@smdw:~/.ssh/

#测试
ssh smdw

安装GPDB master（mdw）

source /usr/local/greenplum-db/greenplum_path.sh

gpseginstall -f host_file -u gpadmin -p gpadmin#确保gpadmin有访问host_file的权限

确认安装master（mdw）
```
gpssh -f host_file -e ls -l $GPHOME
```
如有密码提示
```
gpssh-exkeys -f /home/gpadmin/host_file
```

创建数据存储区域

master（mdw）

mkdir /data/
mkdir /data/master
chown -R gpadmin:gpadmin /data/

standby master(smdw) - 在master（mdw）上远程创建

source /usr/local/greenplum-db/greenplum_path.sh
gpssh -h smdw -e 'mkdir /data/'
gpssh -h smdw -e 'mkdir /data/master'
gpssh -h smdw -e 'chown -R gpadmin:gpadmin /data/'

segment（每个）

gpssh -f hostfile_segonly -e 'mkdir /data'
gpssh -f hostfile_segonly -e 'mkdir /data/primary'
gpssh -f hostfile_segonly -e 'mkdir /data/mirror'
gpssh -f hostfile_segonly -e 'chown -R gpadmin:gpadmin /data/'

配置NTP

master（mdw）

vi /etc/ntp.conf

# Permit time synchronization with our time source, but do not
# permit the source to query or modify the service on this system.
restrict default nomodify 
restrict -6 default kod nomodify notrap nopeer noquery

# Permit all access over the loopback interface.  This could
# be tightened as well, but to do so would effect some of
# the administrative functions.
restrict 127.0.0.1
restrict -6 ::1

# Hosts on local network are less restricted.
#restrict 192.168.1.0 mask 255.255.255.0 nomodify notrap

# Use public servers from the pool.ntp.org project.
# Please consider joining the pool (http://www.pool.ntp.org/join.html).
server cn.pool.ntp.org

standby master（smdw）
```
vi /etc/ntp.conf
```

server mdw prefer
server cn.pool.ntp.org

segment

vi /etc/ntp.conf

server mdw perfer
server smdw

在master（mdw）主机，使用NTP守护进程同步所有Segment主机的系统时钟
```
gpssh -f host_file -v -e 'ntpd'
```
开启各个NTP客户机的ntpd服务

/etc/init.d/ntpd start
chkconfig --level 35 ntpd on#进行一次同步ntpdate cn.pool.ntp.org

安装前系统环境检查

检查操作系统配置

su gpadmin

source /usr/local/greenplum-db/greenplum_path.sh
gpssh -f host_file -e hostname
gpcheck -f host_file -m mdw -s smdw

硬件环境检查

gpcheckperf -f host_file -r N -d /tmp > subnet1.out
gpcheckperf -f hostfile_segonly -d /data/mirror -r ds
