p5-thhidam-datacle-green01
p5-thhidam-datacle-green03
一、系统设置（所有主机）
1、操作系统环境
CentOS 7.5.1804，64位操作系统，没有更新过
[root@localhost tools]# cat /etc/redhat-release
CentOS Linux release 7.5.1804 (Core) 2、关闭防火墙
systemctl stop firewalld.service #停止firewall
systemctl disable firewalld.service3、关闭NetworkManager
systemctl stop NetworkManager
4、关闭selinux
root@p5-thhidam-datacle-green01 gpAdminLogs]# 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
5、配置/etc/sysctl.conf

* hard nproc 1310727、手动执行命令让参数生效，也可以重启系统
#sysctl -p8、修改/etc/hosts文件配置主机与ip地址的映射
192.xxxx.x.x p5-thhidam-datacle-green01
192.xx.x.x p5-thhidam-datacle-green02
192.x.x.x p5-thhidam-datacle-green039、创建gpadmin用户
--每台服务器都做
groupadd -g 530 gpadmin
useradd -g 530 -u 530 -m -d /data/gpadmin -s /bin/bash gpadmin
chown -R gpadmin:gpadmin /data/gpadmin
echo "gpadmin" | passwd --stdin gpadmin
二、安装和分发
CentOS7.5 部署Greenplum6.14集群源码安装
1 联网安装必要的包（所有机器）
[root@p5-thhidam-datacle-green01~]# yum -y install rsync coreutils glib2 lrzsz sysstat e4fsprogs xfsprogs ntp readline-devel zlib zlib-devel openssl openssl-devel pam-devel libxml2-devel libxslt-devel python-devel tcl-devel gcc make smartmontools flex bison perl perl-devel perl-ExtUtils* OpenIPMI-tools openldap openldap-devel logrotate gcc-c++ python-py python-pip libdwarf-devel libzstd-devel yum -y install bzip2-devel libevent-devel apr-devel curl-devel ed python-paramiko python-devel
[root@p5-thhidam-datacle-green01~]# pip3 install --upgrade pip
[root@p5-thhidam-datacle-green01~]# pip3 install lockfile paramiko setuptools epydoc psutil
[root@p5-thhidam-datacle-green01~]# pip3 install --upgrade setuptools2 master节点解压代码编译安装Greenplum
或者 ：
wget https://github.com/greenplum-db/gpdb/releases/download/6.14.1/6.14.1-src-full.tar.gz- 编译
[root@p5-thhidam-datacle-green01 gpdb-5.15.1]# ./configure --prefix=/data/gpadmin --with-gssapi --with-pgport=5432 --with-libedit-preferred --with-perl --with-python --with-openssl --with-pam --with-krb5 --with-ldap --with-libxml --enable-cassert --enable-debug --enable-testutils --enable-debugbreak --enable-depend --disable-orca

若出现：则说明安装成功。
3. 分发文件
因为只在master上安装了Greenplum，所以下面要将安装包批量发送到每个slave机器上，才能算是整个Greenplum集群安装了Greenplum。
先在master主节点上创建GP的tar文件，其中gpsqlpwd是安装路径。
[root@p5-thhidam-datacle-green01 gpsql]# chown -R gpadmin:gpadmin /data/gpsql/
[root@p5-thhidam-datacle-green01 gpadmin]# gtar -cvf /data/gpadmin/gp.tar /data/gpsql
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
在master主机，以gpadmin用户身份创建以下文本，可在gpadmin目录下创建conf文件夹，用来放这些启动互信信息
--master主机需要做
su - gpadmin
mkdir /data/gpadmin/conf
source /data/gpadmin/greenplum_path.sh
ssh-keygen
ssh-copy-id -i p5-thhidam-datacle-green02
ssh-copy-id -i p5-thhidam-datacle-green03
gpssh-exkeys -f /data/gpadmin/conf/all_hosts
****记住要用master节点ssh一下
ssh gpadmin@p5-thhidam-datacle-green02
ssh gpadmin@p5-thhidam-datacle-green02
编辑 集群列表
[root@p5-thhidam-datacle-green01 conf]# vim /data/gpadmin/conf/all_hosts p5-thhidam-datacle-green01 p5-thhidam-datacle-green02 p5-thhidam-datacle-green03 [root@p5-thhidam-datacle-green01 conf]# vim /data/gpadmin/conf/seg_hosts p5-thhidam-datacle-green02 p5-thhidam-datacle-green03

三、初始化和创建数据库
1 配置.bash_profile 环境变量（每台机器都要配置）
[gpadmin@p5-thhidam-datacle-green01 ~]$ vim .bash_profile
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
PATH=$PATH:$data/.local/bin:$data/bin
export PATH
source /data/gpadmin/greenplum_path.sh
export MASTER_DATA_DIRECTORY=/data/gpadmin/gpadata/gpmaster/gpseg-1
export PGPORT=2346
export PGDATABASE=testDB[gpadmin@p5-thhidam-datacle-green01 ~]$ . ~/.bash_profile
2 同步时钟
