4、安装过程
1）root用户，关闭防火墙
chkconfig iptables off
systemctl stop firewalld.service
systemctl disable firewalld.service
2）root用户，关闭SELINUX
vim /etc/selinux/config
改为：SELINUX=disabled
3）root用户，修改机器名
hostnamectl set-hostname mdw
4）root用户，修改host
vim /etc/hosts
127.0.0.1mdw localhost localhost.localdomain localhost4 localhost4.localdomain4
#::1localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.56.8 mdw mdw
192.168.56.8 sdw1 sdw1
192.168.56.8 sdw2 sdw2
5）root用户，创建组和用户
groupadd -g 530 gpadmin
mkdir /home/gpdata
useradd -u 3030 gpadmin -g gpadmin -d /home/gpdata
passwd gpadmin
6）root用户，配置内核
vi /etc/sysctl.conf
kernel.sem = 250 64000 100 512
kernel.shmmax = 500000000
kernel.shmmni = 4096
kernel.shmall = 4000000000
kernel.sysrq = 1
kernel.core_uses_pid = 1
kernel.msgmnb = 65536
kernel.msgmax = 65536
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.arp_filter = 1
net.core.netdev_max_backlog=10000
vm.overcommit_memory=2
vim /etc/security/limits.conf
* soft nofile 65536
* hard nofile 65536
* soft nproc 131072
* hard nproc 131072
7）root用户，上传程序包
chomd +x greenplum-db-6.0.0-beta.1-rhel7-x86_64.rpm
rpm -Uvh greenplum-db-6.0.0-beta.1-rhel7-x86_64.rpm
#默认安装到/usr/local，授权给gpadmin
chown -R gpadmin /usr/local/greenplum*
chgrp -R gpadmin /usr/local/greenplum*
#设置环境变量
source /usr/local/greenplum-db-6.0.0-beta.1/greenplum_path.sh
8）gpadmin用户， 创建目录
su -l gpadmin
mkdir -p /home/gpdata
mkdir -p /home/gpdata/master
mkdir -p /home/gpdata/gp1
mkdir -p /home/gpdata/gp2
9） gpadmin用户，创建all_host和seg_host文件
cd /home/gpadmin
mkdir gpconfigs
cd gpconfigs
vim all_hosts--包含master和segment的全部主机名称
mdw
sdw1
sdw2
vi all_segs--只包含segment的主机名称
sdw1
sdw2
10）gpadmin用户，设置安装用户的环境变量
cd
vim .bash_profile
【centos|centos 7.x 单机版安装greenplum 6.0】source /usr/local/greenplum-db-6.0.0-beta.1/greenplum_path.sh
export MASTER_DATA_DIRECTORY=/home/gpdata/master/gpseg-1
export PGPORT=5432
export PGUSER=gpadmin
export PGDATABASE=hdw
保存后执行 ： source /home/gpadmin/.bash_profile
vim .bashrc
source /usr/local/greenplum-db-6.0.0-beta.1/greenplum_path.sh
export MASTER_DATA_DIRECTORY=/home/gpdata/master/gpseg-1
export PGPORT=5432
export PGUSER=gpadmin
export PGDATABASE=hdw
保存后执行 ： source /home/gpadmin/.bashrc
11）gpadmin用户，为安装用户设置各个节点的SSH连接
gpssh-exkeys -f /home/gpadmin/gpconfigs/all_hosts
[gpadmin@mdw gpconfigs]$ gpssh -h mdw
=> echo $HOSTNAME
[mdw] mdw
=> exit
[gpadmin@mdw gpconfigs]$ gpssh -h sdw1
=> echo $HOSTNAME
[sdw1] mdw
=> exit
[gpadmin@mdw gpconfigs]$ gpssh -h sdw2
=> echo $HOSTNAME
[sdw2] mdw
=> exit
12）gpadmin用户， 编辑安装配置文件gpinitsystem_config
将/data/greenplum-db-4.2.2.0/docs/cli_help/gpconfigs/gpinitsystem_config
复制到/home/gpadmin/gpconfigs
cp /usr/local/greenplum-db-6.0.0-beta.1/docs/cli_help/gpconfigs/gpinitsystem_config
/home/gpadmin/gpconfigs
#修改为下面这行
declare -a DATA_DIRECTORY=(/home/gpdata/gp1 /home/gpdata/gp1)
#### OS-configured hostname or IP address of the master host.
MASTER_HOSTNAME=mdw
#### File system location where the master data directory
#### will be created.
MASTER_DIRECTORY=/data/master
#### Port number for the master instance.
MASTER_PORT=5432
#### Create a database of this name after initialization.
#DATABASE_NAME=name_of_database
#增加，完成greenplum初始化后创建库hdw
DATABASE_NAME=hdw
#### Specify the location of the host address file here instead of
#### with the the -h option of gpinitsystem.
#MACHINE_LIST_FILE=/home/gpadmin/gpconfigs/hostfile_gpinitsystem
#增加
MACHINE_LIST_FILE=/home/gpadmin/gpconfigs/all_segs
13）root用户，修改ssh_config
用root用户修改192.168.153.190上 /etc/ssh/ssh_config
编辑 GSSAPIAuthentication 为no
用gpadin用户，执行初始化greenplum系统的配置文件
[gpadmin@mdw gpconfigs]$ gpinitsystem -c /home/gpadmin/gpconfigs/gpinitsystem_config
安装过程执行。
14）gpadmin用户，安装完成，验证
[gpadmin@mdw gpconfigs]$ psql -d hdw
15）启停命令
gpstart #正常启动
gpstop #正常关闭
gpstop -M fast #快速关闭
gpstop –r #重启
5、问题处理
1） centos自定义安装，GP安装过程中报错，krb5-devel is needed by greenplum-db...
缺少依赖，使用root账号安装依赖项：
sudo yum install -y epel-release
sudo yum install -y apr-devel bison bzip2-devel cmake3 flex gcc gcc-c++ krb5-devel libcurl-devel libevent-devel libkadm5 libyaml-devel libxml2-devel perl-ExtUtils-Embed Python-devel python-paramiko python-pip python-psutil python-setuptools readline-devel xerces-c-devel zlib-devel
