1.准备工作
每台机器都需要
[root@hadoop001 ~]# yum install -y sed
[root@hadoop001 ~]# yum install -y tar
[root@hadoop001 ~]# yum install -y perl
2.配置系统信息
2.1 配置系统信息，做安装Greenplum的准备工作
Greenplum 数据库版本5.24.2
Linux系统版本 CentOS7.5 64bit
2.1.1 Greenplum集群介绍
这里使用1个master，2个segment的集群，ip为：
172.26.183.103
172.26.183.101
172.26.183.102
其中172.26.183.103为master，其余为segment。
2.1.2 修改/etc/hosts文件（所有的机器都要修改）
这里主要是为之后Greenplum能够在各个节点之间相互通信做准备，添加如下：
格式为：主机ip地址 主机名
[root@hadoop001 ~]# cat /etc/hosts
172.26.183.103 hadoop001 hadoop001
172.26.183.101 hadoop002 hadoop002
172.26.183.102 hadoop003 hadoop003
注意：一定要按照这个格式写，参数代表的含义，上面已经做出说明。
配置了这个文件之后，需要继续修改hostname，即修改/etc/sysconfig/network这个文件
如下（所有机器都要修改）：
[root@hadoop001 ~]# vi /etc/sysconfig/network
# Created by anaconda
NETWORKING=yes
HOSTNAME=hadoop001
注意：这里修改hostname，需要重启之后方可生效，如需立即生效，需使用hostname命令。
[root@hadoop001 ~]# hostname
这里的HOSTNAME一定要与/etc/hosts中的主机名一致，最终可以使用ping命令测试是否配置好了：
[root@hadoop001 ~]# ping hadoop002
[root@hadoop001 ~]# ping hadoop003
一定要使用主机名来测试，使用ip地址测试无效。
2.1.3 创建用户和用户组（所有机器都要创建）
[root@hadoop001 ~]# groupadd -g 530 gpadmin
[root@hadoop001 ~]# useradd -g 530 -u 530 -m -d /home/gpadmin -s /bin/bash gpadmin
[root@hadoop001 ~]# chown -R gpadmin:gpadmin /home/gpadmin
[root@hadoop001 greenplum]# passwd gpadmin
#此处密码设置为：gpadmin
2.1.4 修改系统内核（所有的机器都要修改）
[root@hadoop001 ~]# vi /etc/sysctl.conf
# GP
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.conf.default.rp_filter = 1
net.ipv4.ip_local_port_range = 1025 65535
net.core.netdev_max_backlog = 10000
net.core.rmem_max = 2097152
net.core.wmem_max = 2097152
vm.overcommit_memory = 2
执行以下命令使参数生效:
[root@hadoop001 ~]# sysctl -p
注意：每台机器都要修改，不然就会初始化不成功。
2.1.5 修改文件打开限制（每台机器都要修改）：
[root@hadoop001 ~]# vi /etc/security/limits.conf
* soft nofile 65536
* hard nofile 65536
* soft nproc 131072
* hard nproc 131072
在这个文件末尾，添加上面四行就可以了。
2.1.6 关闭防火墙（每台机器都要）
[root@hadoop001 ~]# service iptables stop
除此之外，还需关闭SELINUX
[root@hadoop001 ~]# cat /etc/selinux/config
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of three two values:
# targeted - Targeted processes are protected,
# minimum - Modification of targeted policy. Only selected processes are protected.
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
好了现在准备工作已经做好了，可以开始安装Greenplum了。
3 安装Greenplum
3.1 创建安装文件目录（每台机器都需要创建）
[root@hadoop001 ~]# mkdir -p /opt/greenplum
[root@hadoop001 ~]# chown -R gpadmin:gpadmin /opt/greenplum
之后安装文件，就放在这个目录下面
3.2 下载安装包
官网 https://network.pivotal.io/products/pivotal-gpdb
注意：下载安装包之前，需要在官网注册账号，方可下载。
3.3 master上安装Greenplum（只需master即可）
上传Greenplum的安装文件greenplum-db-5.24.2-rhel7-x86_64.zip并解压缩。(需要联网权限)
[root@hadoop001 ~]# cd /opt/greenplum
[root@hadoop001 greenplum]# rz
[root@hadoop001 greenplum]# ll
total 274132
-rw-r--r-- 1 root root 280705026 Mar 12 17:37 greenplum-db-5.24.2-rhel7-x86_64.zip
[root@hadoop001 greenplum]# unzip ./greenplum-db-5.24.2-rhel7-x86_64.zip
[root@hadoop001 greenplum]# ll
total 550756
-rwxr-xr-x 1 root root 283260764 Jan 31 02:36 greenplum-db-5.24.2-rhel7-x86_64.bin
-rw-r--r-- 1 root root 280705026 Mar 12 17:37 greenplum-db-5.24.2-rhel7-x86_64.zip
在root用户下，将下载的文件放在CentOS系统中自己能找到的位置即可，给该文件赋予可执行权限，之后执行该文件，即开始安装
[root@hadoop001 greenplum]# chmod +x greenplum-db-5.24.2-rhel7-x86_64.bin
[root@hadoop001 greenplum]# ./greenplum-db-5.24.2-rhel7-x86_64.bin
期间需要修改默认安装目录，输入 /opt/greenplum//greenplum-db-5.24.2之后即可安装成功（yes 后面的第二次提示），此时master上的Greenplum安装成功了。
安装完成后的提示：
********************************************************************************
Installation complete.
Greenplum Database is installed in /opt/greenplum//greenplum-db-5.24.2
Pivotal Greenplum documentation is available
for download at http://gpdb.docs.pivotal.io
********************************************************************************
但是之前我们都是以root身份安装的，所以要将安装目录下的文件的所有者，都修改为gpadmin。
[root@hadoop001 greenplum]# chown -R gpadmin:gpadmin /opt/greenplum
因为只在master上安装了Greenplum，所以接下来要将安装包批量发送到每个segment上，才能算是整个集群完整安装了Greenplum。
下面的操作都是为了连接所有节点，并将安装包发送到每个节点
3.4 创建配置文件
[root@hadoop001 greenplum]# su - gpadmin
[gpadmin@hadoop001 ~]$ ll
total 0
[gpadmin@hadoop001 ~]$ mkdir conf
[gpadmin@hadoop001 ~]$ ll
total 4
drwxrwxr-x 2 gpadmin gpadmin 4096 Mar 13 22:57 conf
[gpadmin@hadoop001 ~]$ cd conf
[gpadmin@hadoop001 conf]$ vi hostlist
hadoop001
hadoop002
hadoop003
[gpadmin@hadoop001 conf]$ vi seg_hosts
hadoop002
hadoop003
[gpadmin@hadoop001 conf]$ ll
total 8
-rw-rw-r-- 1 gpadmin gpadmin 30 Mar 13 22:58 hostlist
-rw-rw-r-- 1 gpadmin gpadmin 30 Mar 13 23:05 seg_hosts
注意:此时需要转换成gpadmin身份来操作了，按照上面的文件内容创建hostlist和seg_hosts文件备用。
hostlist存储了所有节点的主机名，seg_hosts存储了所有从节点的主机名。
这里文件中的hadoop001、hadoop002、hadoop003
即为之前在 /etc/hosts文件中配置的最后一个参数。
3.5 打通所有节点
greenplum_path.sh中保存了运行Greenplum的一些环境变量设置，包括GPHOOME、PYTHONHOME等设置。
[gpadmin@hadoop001 ~]$ source /opt/greenplum/greenplum-db/greenplum_path.sh
[gpadmin@hadoop001 ~]$ gpssh-exkeys -f /home/gpadmin/conf/hostlist
[STEP 1 of 5] create local ID and authorize on local host
... /home/gpadmin/.ssh/id_rsa file exists ... key generation skipped
[STEP 2 of 5] keyscan all hosts and update known_hosts file
[STEP 3 of 5] authorize current user on remote hosts
... send to hadoop002
***
*** Enter password for hadoop002:
... send to hadoop003
[STEP 4 of 5] determine common authentication file content
[STEP 5 of 5] copy authentication files to all remote hosts
... finished key exchange with hadoop002
... finished key exchange with hadoop003
[INFO] completed successfully
注意：
(1)首次执行gpssh-exkeys命令时，在[STEP 3 of 5]，要输入每个segment节点的gpadmin用户的密码。
(2)gpssh-exkeys命令使用的时候一定要用gpadmin身份，因为这个命令会生成ssh的免密码登录的秘钥，在/home/gpadmin/.ssh这里。如果以root身份使用gpssh-exkeys命令，那么生成的.ssh秘钥在root的home下面或者是在/home/gpadmin下面但是是root的所有者，如果之后使用gpadmin身份执行相应操作的时候就没有权限。
[INFO] completed successfully 这就说明成功打通了，之后就可以使用下面的命令开启批量操作，如下：
[gpadmin@hadoop001 ~]$ gpssh -f /home/gpadmin/conf/hostlist
=> pwd
[hadoop001] /home/gpadmin
[hadoop003] /home/gpadmin
[hadoop002] /home/gpadmin
=> exit
这里pwd命令是linux中的查看路径命令，这里也是查看一下批量操作时所处的位置，从中可以看到同时连接到了3个节点。这里如果/etc/hosts文件中参数只设置了两个，没有设置主机名，就只能同时连接2个节点，而且是随机的。
这里我们只是测试一下，exit之后先做一些其他的操作。
3.6 将安装包分发到每个子节点
打通之后需要将master中的greenplum安装包批量复制到各个segment节点上。
打包：
[gpadmin@hadoop001 ~]$ cd /opt/greenplum/
[gpadmin@hadoop001 greenplum]$ tar -cf gp-5.24.tar ./greenplum-db-5.24.2/
[gpadmin@hadoop001 greenplum]$ ll
total 1238124
-rw-rw-r-- 1 gpadmin gpadmin 703856640 Mar 13 23:17 gp-5.24.tar
lrwxrwxrwx 1 gpadmin gpadmin 21 Mar 13 22:52 greenplum-db -> greenplum-db-5.24.2
drwxr-xr-x 11 gpadmin gpadmin 4096 Mar 13 22:52 greenplum-db-5.24.2
-rwxr-xr-x 1 gpadmin gpadmin 283260764 Jan 31 02:36 greenplum-db-5.24.2-rhel7-x86_64.bin
-rw-r--r-- 1 gpadmin gpadmin 280705026 Mar 12 17:37 greenplum-db-5.24.2-rhel7-x86_64.zip
然后利用gpscp命令将这个文件复制到每一台机器上：
[gpadmin@hadoop001 greenplum]$ gpscp -f /home/gpadmin/conf/seg_hosts gp-5.24.tar =:/opt/greenplum/
如果没有意外，就批量复制成功了，可以去子节点的相应文件夹查看，之后要将tar包解压，我们使用批量操作。
[gpadmin@hadoop001 greenplum]$ cd ~/conf/
[gpadmin@hadoop001 conf]$ gpssh -f seg_hosts
=> cd /opt/greenplum
[hadoop003]
[hadoop002]
=> tar -xf gp-5.24.tar
[hadoop003]
[hadoop002]
#建立软链接
=> ln -s greenplum-db-5.24.2 greenplum-db
[hadoop003]
[hadoop002]
=> ll
[hadoop003] total 687368
[hadoop003] -rw-rw-r-- 1 gpadmin gpadmin 703856640 Mar 13 23:24 gp-5.24.tar
[hadoop003] lrwxrwxrwx 1 gpadmin gpadmin 21 Mar 13 23:26 greenplum-db -> ./greenplum-db-5.24.2
[hadoop003] drwxr-xr-x 11 gpadmin gpadmin 4096 Mar 13 22:52 greenplum-db-5.24.2
[hadoop002] total 687368
[hadoop002] -rw-rw-r-- 1 gpadmin gpadmin 703856640 Mar 13 23:24 gp-5.24.tar
[hadoop002] lrwxrwxrwx 1 gpadmin gpadmin 21 Mar 13 23:26 greenplum-db -> ./greenplum-db-5.24.2
[hadoop002] drwxr-xr-x 11 gpadmin gpadmin 4096 Mar 13 22:52 greenplum-db-5.24.2
#(可以使用ll查看一下是否已经安装成功)
=> exit
这样就完成了所有节点的安装。
4. 初始化数据库
在初始化之前的的几个步骤都是做一些准备工作。
4.1 批量创建Greenplum数据存放目录
[gpadmin@hadoop001 conf]$ gpssh -f hostlist
=> mkdir gpdata
[hadoop002]
[hadoop001]
[hadoop003]
=> cd gpdata
[hadoop002]
[hadoop001]
[hadoop003]
=> mkdir gpmaster gpdatap1 gpdatap2 gpdatam1 gpdatam2
[hadoop002]
[hadoop001]
[hadoop003]
=> ll
[hadoop002] total 20
[hadoop002] drwxrwxr-x 2 gpadmin gpadmin 4096 Mar 13 23:29 gpdatam1
[hadoop002] drwxrwxr-x 2 gpadmin gpadmin 4096 Mar 13 23:29 gpdatam2
[hadoop002] drwxrwxr-x 2 gpadmin gpadmin 4096 Mar 13 23:29 gpdatap1
[hadoop002] drwxrwxr-x 2 gpadmin gpadmin 4096 Mar 13 23:29 gpdatap2
[hadoop002] drwxrwxr-x 2 gpadmin gpadmin 4096 Mar 13 23:29 gpmaster
[hadoop001] total 20
[hadoop001] drwxrwxr-x 2 gpadmin gpadmin 4096 Mar 13 23:29 gpdatam1
[hadoop001] drwxrwxr-x 2 gpadmin gpadmin 4096 Mar 13 23:29 gpdatam2
[hadoop001] drwxrwxr-x 2 gpadmin gpadmin 4096 Mar 13 23:29 gpdatap1
[hadoop001] drwxrwxr-x 2 gpadmin gpadmin 4096 Mar 13 23:29 gpdatap2
[hadoop001] drwxrwxr-x 2 gpadmin gpadmin 4096 Mar 13 23:29 gpmaster
[hadoop003] total 20
[hadoop003] drwxrwxr-x 2 gpadmin gpadmin 4096 Mar 13 23:29 gpdatam1
[hadoop003] drwxrwxr-x 2 gpadmin gpadmin 4096 Mar 13 23:29 gpdatam2
[hadoop003] drwxrwxr-x 2 gpadmin gpadmin 4096 Mar 13 23:29 gpdatap1
[hadoop003] drwxrwxr-x 2 gpadmin gpadmin 4096 Mar 13 23:29 gpdatap2
[hadoop003] drwxrwxr-x 2 gpadmin gpadmin 4096 Mar 13 23:29 gpmaster
=> exit
4.2 配置.bash_profile环境变量（每台机器都要）
编辑.bash_profile文件，添加以下内容：
[gpadmin@hadoop001 conf]$ cd
[gpadmin@hadoop001 ~]$ vi .bash_profile
source /opt/greenplum/greenplum-db/greenplum_path.sh
export MASTER_DATA_DIRECTORY=/home/gpadmin/gpdata/gpmaster/gpseg-1
export PGPORT=5432
#export PGDATABASE=testDB
export PGDATABASE=postgres
[gpadmin@hadoop001 ~]$ source .bash_profile
注意：PGPORT指的是你安装greenplum数据库的端口号。
这里有个问题，Greenplum自己会安装一个Python包，是2.6.6的。而CentOS6.5本身自带有一个Python包，是2.6.2的，设置了以上的环境变量了之后，使用yum安装一些软件的时候就会出现问题（因为yum是基于Python的），因为系统就发现自己有两个Python包，他不知道用哪一个了。我还没有试过更新系统的Python包，需要安装软件的时候，我就将环境变量都注释掉，安装完之后再让他生效。
4.3 创建初始化配置文件（只需master即可）
[gpadmin@hadoop001 ~]$ vi /home/gpadmin/conf/gpinitsystem_config
# FILE NAME: gpinitsystem_config
