本文主要是介绍Hawq安装搭建，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
环境列表
操作系统：centos 7 64位
Hawq版本：git clonehttps://git-wip-us.apache.org/repos/asf/incubator-hawq.git
虚拟机主机列表
| 主机名 | Ip |
| hawq1 | 192.168.204.201 |
| hawq2 | 192.168.204.202 |
| hawq3 | 192.168.204.203 |

一hawq编译安装(root用户操作hawq1, 192.168.204.201)
1操作系统环境准备
安装centos7,设置主机名，关闭防火墙，关闭selinux
chkconfig iptables off
chkconfig ip6tables off
systemctl stop firewalld.service
sestatus //查询
vi /etc/selinux/config //关闭selinux
2软件环境准备
curl -L"https://bintray.com/wangzw/rpm/rpm" -o/etc/yum.repos.d/bintray-wangzw-rpm.repo
yum install -y epel-release
yum makecache
yum install -y man passwd sudo tar whichgit mlocate links make bzip2 net-tools \

碰到问题：
Transaction check error:
file /usr/lib/systemd/system/blk-availability.service from install ofdevice-mapper-7:1.02.107-5.el7.x86_64 conflicts with file from packagelvm2-7:2.02.105-14.el7.x86_64

rpm -qa | grep lvm2
yum erase lvm2-2.02.105-14.el7.x86_64
3下载incubator-hawq
git clonehttps://git-wip-us.apache.org/repos/asf/incubator-hawq.git
4安装libyarn
cd depends/libyarn/
mkdir build
cd build
../bootstrap --prefix=/usr/local/
make
sudo make install
把结果*.so文件复制至/usr/lib或者如下操作
ln -s /usr/local/libyarn.so /usr/lib
ln -s /usr/local/libyarn.so.1 /usr/lib
ln -s /usr/local/libyarn.so.0.1.10 /usr/lib
ldconfig
5配置及编译hawq(注意保持网络通畅)
./configure --prefix=/hawq
make
make install
二虚拟机制作
第一部分操作完成后,保存虚拟机hawq1，然后copy成2份，然后分别打开虚拟机根据虚拟机主机列表更改主机名，IP等操作，然后互ping IP，确认虚机机之间网络通畅。
三hadoop 2.X系统安装配置（可以利用gpssh设置互信等），然后启动运行，
hadoop 2.X系统安装配置参考：http://blog.csdn.net/sunziyue/article/details/50735192
之后再配置好hawq软件中相关配置文件(hawq用户操作)。
四初始化hawq实例(hawq用户操作)
source /install/dir/greenplum_path.sh
hawq init cluster
hawq stop/restart/start cluster
