基本环境：
| server | IP |
|---|---|
| MDW | 172.16.16.31 |
| SDW1 | 172.16.16.34 |
| SDW2 | 172.16.16.35 |
1：检查操作系统是否符合要求，以及系统设置。
我这里使用的系统是CentOS ,操作系统要求CentOS64-bit 6.x or 7.x，CentOS最好是7以上版本。 然后关闭selinux，iptables
cat /etc/selinux/config SELINUX=disabled
查看状态：
[root@16-31 mail]# sestatus SELinux status: disabled
关闭iptables
[root@16-31 ~]# chkconfig iptables off [root@16-31 ~]# chkconfig --list |grep iptables iptables 0:off 1:off 2:off 3:off 4:off 5:off 6:off
配置系统参数，官方给出了一些建议的配置：
vi /etc/sysctl.conf
然后修改
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.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
第二个文件也有一些需要修改的地方
vi /etc/security/limits.conf
添加以下内容：
* soft nofile 65536 * hard nofile 65536 * soft nproc 131072 * hard nproc 131072
修改IO调度算法：
echo deadline > /sys/block/sr0/queue/scheduler
然后重启机器。文件系统最好使用XFS。 禁用THP：
[root@16-31 ~]# grubby --update-kernel=ALL --args="transparent_hugepage=never" [root@16-31 ~]# cat /sys/kernel/mm/*transparent_hugepage/enabled [always] madvise never [always] madvise never
2：安装Greenplum
我们下载的是5.0版本，使用二进制发行版安装，使用root用户登录，最好建立一个单独的用户进行安装。 所有节点创建用户
useradd gpadmin
先进行解压：
[root@16-31 sa]# unzip greenplum-db-5.0.0-rhel7-x86_64.zip [root@16-31 gptest]# groupadd gpadmin [root@16-31 gptest]# useradd -r -g gpadmin -s /bin/false gpadmin
开始安装：
[root@16-31 gptest]# /bin/bash greenplum-db-5.0.0-rhel7-x86_64.bin
安装过程会有提示：
I HAVE READ AND AGREE TO THE TERMS OF THE ABOVE PIVOTAL SOFTWARE LICENSE AGREEMENT. ******************************************************************************** Do you accept the Pivotal Database license agreement? [yes|no] ******************************************************************************** yes ******************************************************************************** Provide the installation path for Greenplum Database or press ENTER to accept the default installation path: /usr/local/greenplum-db-5.0.0 ******************************************************************************** /home/greenplum-db-5.0.0 ******************************************************************************** Install Greenplum Database into /home/greenplum-db-5.0.0?

Greenplum Database is installed in /home/greenplum-db-5.0.0 Pivotal Greenplum documentation is available for download at http://gpdb.docs.pivotal.io ********************************************************************************
安装以后的我们进去看一下具体的安装目录：
[root@16-31 greenplum-db-5.0.0]# ls bin docs etc ext greenplum_path.sh include lib pxf sbin share
看看目录具体作用：
greenplum_path.sh：配置文件 bin目录：主要是一些工具，其中也包括pgsql等 docs目录：帮助文件和一些配置文件 etc:示例配置文件和一些工具的配置文件 ext：GP的一些绑定程序，我们看到现在只有一个python include：GP的一些C的头文件 lib：库文件 sbin：内部脚本和程序 share ：共享文件夹
然后我们在另外两台机器上也执行相同脚本进行安装和部署或者使用gpseginstall进行安装。这里我们使用第二种方法 先修改host文件：
172.16.16.31 mdw 172.16.16.34 sdw1 172.16.16.35 sdw2
初始化一下环境变量，这里我们可以看到两个
[root@mdw greenplum-db-5.0.0]# source /home/greenplum-db-5.0.0/greenplum_path.sh [root@mdw greenplum-db-5.0.0]# source /home/greenplum-db/greenplum_path.sh
两个文件是一模一样的选择任何都是一样的。然后创建一个文件：
[root@16-31 greenplum-db-5.0.0]# cat my_host_list_file mdw sdw1 sdw2
配置SSH的免密链接：
[gpadmin@mdw sa]$ gpssh-exkeys -f /home/gpdb/hostlist [STEP 1 of 5] create local ID and authorize on local host [STEP 2 of 5] keyscan all hosts and update known_hosts file [STEP 3 of 5] authorize current user on remote hosts ... send to sdw1 *** *** Enter password for sdw1: ... send to sdw2 [STEP 4 of 5] determine common authentication file content [STEP 5 of 5] copy authentication files to all remote hosts ... finished key exchange with sdw1 ... finished key exchange with sdw2 [INFO] completed successfully
在各个节点创建所必须的文件夹：
[gpadmin@mdw sa]$ gpssh -f /home/gpdb/seghostlist -e -v ‘sudo mkdir -p /home/greenplum && sudo chown -R gpadmin /home/greenplum‘ [WARN] Reference default values as $MASTER_DATA_DIRECTORY/gpssh.conf could not be found Using delaybeforesend 0.05 and prompt_validation_timeout 1.0 [Reset ...] [INFO] login sdw2 [INFO] login sdw1 [sdw2] sudo mkdir -p /home/greenplum && sudo chown -R gpadmin /home/greenplum [sdw1] sudo mkdir -p /home/greenplum && sudo chown -R gpadmin /home/greenplum [INFO] completed successfully [Cleanup...]
下面开始安装：

然后给这个账号暂时赋予管理员的权限：
[root@mdw ~]# visudo gpadmin ALL=(ALL) ALL gpadmin ALL=(ALL) NOPASSWD:ALL
安装完成以后我们检查一下安装：
[gpadmin@mdw home]$ gpssh -f /home/gpdb/seghostlist -e ls -l $GPHOME [sdw1] ls -l /home/greenplum/greenplum-db/. [sdw1] total 40 [sdw1] drwxr-xr-x 8 gpadmin root 4096 Sep 8 05:20 bin [sdw1] drwxr-xr-x 4 gpadmin root 4096 Sep 8 05:02 docs [sdw1] drwxr-xr-x 2 gpadmin root 4096 Sep 8 05:02 etc [sdw1] drwxr-xr-x 3 gpadmin root 4096 Sep 8 05:02 ext [sdw1] -rw-r--r-- 1 gpadmin root 738 Dec 14 2017 greenplum_path.sh [sdw1] drwxr-xr-x 6 gpadmin root 4096 Sep 8 05:02 include [sdw1] drwxr-xr-x 7 gpadmin root 4096 Sep 8 05:02 lib [sdw1] drwxr-xr-x 8 gpadmin root 4096 Sep 8 05:07 pxf [sdw1] drwxr-xr-x 2 gpadmin root 4096 Sep 8 05:07 sbin [sdw1] drwxr-xr-x 5 gpadmin root 4096 Sep 8 04:59 share [sdw2] ls -l /home/greenplum/greenplum-db/.

接下来我们创建数据目录的空间：
[gpadmin@mdw home]$ cd greenplum/
[gpadmin@mdw greenplum]$ ls
greenplum-db greenplum-db-5.0.0
[gpadmin@mdw greenplum]$ source /home/greenplum/greenplum-db-5.0.0/greenplum_path.sh
[gpadmin@mdw greenplum]$ gpssh -f /home/gpdb/hostlist -e ‘mkdir -p /home/greenplum/data‘
[sdw1] mkdir -p /home/greenplum/data
[sdw2] mkdir -p /home/greenplum/data
[ mdw] mkdir -p /home/greenplum/data
[gpadmin@mdw greenplum]$ gpssh -h mdw -e ‘mkdir -p /home/greenplum/data/master‘
[mdw] mkdir -p /home/greenplum/data/master
[gpadmin@mdw greenplum]$ gpssh -f /home/gpdb/seghostlist -e ‘mkdir -p /home/greenplum/data/{primary,mirror}‘
[sdw1] mkdir -p /home/greenplum/data/{primary,mirror}
[sdw2] mkdir -p /home/greenplum/data/{primary,mirror}
设置环境变量：
[gpadmin@sdw1 data]$ cat /home/greenplum/greenplum-db-5.0.0/greenplum_path.sh >>/home/gpadmin/.bash_profile [gpadmin@sdw1 data]$ source /home/gpadmin/.bash_profile [gpadmin@sdw1 data]$ gps gpscp gpseginstall gpsourcify.pl gpssh-exkeys gpstate gpstringsubs.pl gpsd gpsmon gpssh gpstart gpstop gpsys1 [gpadmin@mdw .ssh]$ cat /home/greenplum/greenplum-db-5.0.0/greenplum_path.sh>> ~/.bashrc [gpadmin@mdw .ssh]$ scp ~/.bashrc sdw1:~ .bashrc 100% 969 1.0KB/s 00:00 [gpadmin@mdw .ssh]$ scp ~/.bashrc sdw2:~ .bashrc
同步时钟： 在Master主机上编辑/etc/ntp.conf来设置如下内容： server 127.127.1.0 在Segment主机上编辑/etc/ntp.conf server mdw
[root@mdw ntp]# su gpadmin [gpadmin@mdw ntp]$ gpssh -f /home/gpdb/hostlist -v -e ‘ntpd‘ [WARN] Reference default values as $MASTER_DATA_DIRECTORY/gpssh.conf could not be found Using delaybeforesend 0.05 and prompt_validation_timeout 1.0 [Reset ...] [INFO] login sdw1 [INFO] login mdw [INFO] login sdw2 [sdw1] ntpd [sdw1] -bash: ntpd: command not found [ mdw] ntpd [ mdw] -bash: ntpd: command not found [sdw2] ntpd [sdw2] -bash: ntpd: command not found [INFO] completed successfully [Cleanup...]
上面的都完成以后，我们来开始初始化GP之前的检查：

配置文件如下：
ARRAY_NAME="Greenplum Data Platform" SEG_PREFIX=gpseg PORT_BASE=40000 declare -a DATA_DIRECTORY=(/home/greenplum/data/primary /home/greenplum/data/primary) MASTER_HOSTNAME=mdw MASTER_DIRECTORY=/home/greenplum/data/master MASTER_PORT=5432 TRUSTED_SHELL=ssh CHECK_POINT_SEGMENTS=8 ENCODING=UNICODE declare -a MIRROR_DATA_DIRECTORY=(/home/greenplum/data/mirror /home/greenplum/data/mirror) MACHINE_LIST_FILE=/home/gpdb/seghostlist
下面就开始初始化数据库吧：
