一、Greenplum简介
Greenplum数据库系统体系结构的概述。

Greenplum数据库通过在多个服务器或主机之间分配负载来存储和处理大量数据。
Greenplum中的逻辑数据库是一组单独的PostgreSQL数据库，这些数据库协同工作以呈现单个数据库映像。该主是入口点，Greenplum的数据库系统。
它是用户连接并提交SQL语句的数据库实例。
主服务器协调系统中其他数据库实例（称为segment）的工作负载，这些实例处理数据处理和存储。这些段通过互连（Greenplum数据库的网络层）相互之间和主机进行通信 。
当前安装的测试环境如下所示：
主机名 ip 配置 系统版本 用途 数据库安装位置 数据安装目录
mdwh1 172.16.101.112 6c,16G CentOS Linux release 7.5.1804 (Core) master主节点 /usr/local/greenplum-db /data/master
sdwh1 172.16.101.113 6c,16G CentOS Linux release 7.5.1804 (Core) segment节点,mirro节点 /usr/local/greenplum-db /data/primary,/data/mirro
sdwh1 172.16.101.114 6c,16G CentOS Linux release 7.5.1804 (Core) segment节点,mirro节点 /usr/local/greenplum-db /data/primary,/data/mirro
注意

二、配置系统（所有服务器都需要配置）
1. 确保您的主机系统满足平台要求中所述的要求。
2. 禁用SELinux和防火墙软件。
禁用SELinux

1.以root用户身份检查SELinux的状态：

[root@mdwh ~]# sestatus

SELinux status: disabled

2.如果未禁用SELinux，请通过编辑/etc/selinux/config文件：

SELINUX=disabled

禁用防火墙

systemctl stop firewalld && systemctl disable firewalld.service
3. 设置所需的操作系统参数。
vi /etc/sysctl.conf
参考参数如下:

kernel.shmall = 4000000000
kernel.shmmax = 500000000
kernel.shmmni = 4096
vm.overcommit_memory = 2
vm.overcommit_ratio = 95
net.ipv4.ip_local_port_range = 10000 65535
kernel.sem = 500 2048000 200 40960
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_max_syn_backlog = 4096
net.ipv4.conf.all.arp_filter = 1
net.core.netdev_max_backlog = 10000
net.core.rmem_max = 2097152
net.core.wmem_max = 2097152
vm.swappiness = 10
vm.zone_reclaim_mode = 0
vm.dirty_expire_centisecs = 500
vm.dirty_writeback_centisecs = 100
vm.dirty_background_ratio = 0 # See Note 5
vm.dirty_ratio = 0
vm.dirty_background_bytes = 1610612736
vm.dirty_bytes = 4294967296
修改立即生效
sysctl -p
1
修改文件数，进程数的限制vi /etc/security/limits.conf,在文件末尾新增以下内容
* soft nofile 524288
* hard nofile 524288
* soft nproc 131072
* hard nproc 131072
4. 创建ip和主机名映射：vi /etc/hosts
172.16.101.112 mdwh
172.16.101.113 sdwh1
172.16.101.114 sdwh2
5. 创建gpadmin帐户。
groupadd -g 530 gpadmin

useradd -g 530 -u 530 -m -d /home/gpadmin -s /bin/bash gpadmin

chown -R gpadmin:gpadmin /home/gpadmin

echo "gpadmin" | passwd --stdin gpadmin
6. 配置root和gpadmin用户SSH免密登录
root用户登录主节点：

1. ssh-keygen 生成公钥和私钥
2. 用ssh-copy-id将公钥复制到远程机器中
ssh-copy-id sdwh1
ssh-copy-id sdwh2

gpadmin用户登录主节点：

1. ssh-keygen 生成公钥和私钥
2. 用ssh-copy-id将公钥复制到远程机器中
ssh-copy-id sdwh1
ssh-copy-id sdwh2
三、安装Greenplum数据库
下载安装包，放到master节点服务器上
1.下载greenplum-db-6.0.0-rhel7-x86_64.rpm文件，下载地址https://github.com/greenplum-db/gpdb/releases/tag/6.0.0

2.yum install greenplum-db-6.0.0-rhel7-x86_64.rpm或者
rpm -ivh greenplum-db-6.0.0-rhel7-x86_64.rpm
master节点开始安装rpm包
[root@mdwh ~]# rpm -ivh greenplum-db-6.0.0-rhel7-x86_64.rpm

新建gpconfigs文件夹，存放gp安装过程中所使用到的配置文件
[root@mdwh ~]# mkdir /usr/local/greenplum-db-6.0.0/gpconfigs

[root@mdwh gpadmin]# cd /usr/local/greenplum-db-6.0.0/gpconfigs

allhosts: 所有服务器的主机名
seghosts: 所有Segment节点的主机名

[root@mdwh gpconfigs]# vi allhosts
写入
mdwh
sdwh1
sdwh2

[root@mdwh gpconfigs]# vi seghosts
写入
sdwh1
sdwh2

通过gpssh在所有的segment节点进行安装rpm包
以下命令以重做ssh密钥交换
[root@mdwh gpconfigs]# gpssh-exkeys -f seghosts
[STEP 1 of 5] create local ID and authorize on local host
... /root/.ssh/id_rsa file exists ... key generation skipped

[STEP 2 of 5] keyscan all hosts and update known_hosts file

[STEP 3 of 5] retrieving credentials from remote hosts

执行具体的安装操作
1. 通过gpssh -f seghosts连接上所有的segment节点

[root@mdwh gpconfigs]# gpssh -f seghosts
=> pwd
[sdwh1] /root
[sdwh2] /root
=> pwd
[sdwh1] /root
[sdwh2] /root

2. 从主机复制rpm包

13.查看segment状态 gpstate -m

设置任何ip都可访问greenplum
1. 进入master节点服务器

2. 编辑pg_hba.conf

[gpadmin@mdwh gpconfigs]$ vim /data/master/gpseg-1/pg_hba.conf
尾行加入：host all all 0.0.0.0/0 trust
3. 使用仅重新加载配置文件更改的greenplum重启命令

port：5432
initail Database：postgres
username：gpadmin
password：gpadmin

四、启动和停止Greenplum数据库
启动Greenplum数据库
gpstart
1
重新启动Greenplum数据库，停止Greenplum数据库系统，然后重新启动它。
gpstop -r
1
仅重新加载配置文件更改，将更改重新加载到Greenplum数据库配置文件，而不会中断系统。
gpstop -u
1
在维护模式下启动主机，仅启动主服务器以执行维护或管理任务，而不会影响段上的数据。
gpstart -m
1
停止Greenplum数据库
gpstop
1
要以快速模式停止Greenplum数据库
gpstop -M fast
