RHEL6.2详细安装greenplum-db-4.3.5.4(part one)
因公司原有的Oracle数据库已经无法满足当前的实际应用，现需要跟换数据库系统，综合考虑选择greenplum分布式数据库。在安装部署中遇到各种问题，都一一解决，如有错误的地方，请指正，谢谢！
物理环境
硬件环境：
3台台式机
1台6G内存的作为master，操作系统为RHEL6.2，最小化安装
2台4G联想电脑安装虚拟机vmwareworkstation11,其上各安装两台RHEL6.2，最小化安装
分别的IP是
master：168.168.168.16
台式机的windows的IP为
segment1:168.168.168.17
segment2:168.168.168.18
虚拟机：
segment1-1:168.168.168.20
segment1-2:168.168.168.22
segment2-1:168.168.168.19
segment2-2:168.168.168.21
基础配置
首先需要关闭防火墙，selinux
[root@master ~]#service iptables stop
[root@master ~]# chkconfig iptables off
[root@master ~]# vi /etc/sysconfig/selinux 修改SELINUX参数为disabled
# This file controls the state of SELinuxon the system.
# SELINUX= can take one of these threevalues:
# 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 these twovalues:
# targeted - Targeted processes are protected,
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
编辑hosts文件
[root@master ~]# vi /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
168.168.168.16 master
168.168.168.20 segment1-1
168.168.168.22 segment1-2
168.168.168.19 segment2-1
168.168.168.21 segment2-2
