一、 HAWQ2.3.0環境準備【全部主機節點】：
1， vim /etc/sysctl.conf,編輯如下內容:
kernel.shmmax= 1000000000
kernel.shmmni= 4096
kernel.shmall= 4000000000
kernel.sem= 250 512000 100 2048
kernel.sysrq= 1
kernel.core_uses_pid= 1
kernel.msgmnb= 65536
kernel.msgmax= 65536
kernel.msgmni= 2048
net.ipv4.tcp_syncookies= 0
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= 200000
net.ipv4.conf.all.arp_filter= 1
net.ipv4.ip_local_port_range= 1281 65535
net.core.netdev_max_backlog= 200000
vm.overcommit_memory= 2
fs.nr_open= 3000000
kernel.threads-max= 798720
kernel.pid_max= 798720
#increase network
net.core.rmem_max=2097152
net.core.wmem_max=2097152
保存退出後，使用命令“sysctl -p” 使之生效：
sysctl -p
2， vim /etc/security/limits.conf 編輯如下內容:
* soft nofile 2900000
* hard nofile 2900000
* soft nproc 131072
* hard nproc 131072
重新登錄以使配置生效，或者使用命令臨時設置一下：
ulimit -n 10240
3， 添加gpadmin用戶（greeplum admin縮寫），使用/opt/gpadmin作爲主目錄
useradd --home=/opt/gpadmin/ --no-create-home --comment "HAWQ admin" gpadmin
echo gpadmin | passwd --stdin gpadmin
mkdir /opt/gpadmin
chown gpadmin:gpadmin /opt/gpadmin
2，添加gpadmin到/etc/sudoers，編輯該文件，添加如下行
gpadmin ALL=(ALL) NOPASSWD:ALL
3， 配置gpadmin用戶的ssh【免密互訪】
4， 準備軟件包依賴項：
libgsasl is needed by apache-hawq-2.3.0.0-el7.x86_64
protobuf >= 2.5.0 is needed by apache-hawq-2.3.0.0-el7.x86_64
net-snmp-libs is needed by apache-hawq-2.3.0.0-el7.x86_64
thrift >= 0.9.1 is needed by apache-hawq-2.3.0.0-el7.x86_64
boost >= 1.53.0 is needed by apache-hawq-2.3.0.0-el7.x86_64
其中gcc gcc-c++ protobuf net-snmp-libs boots可直接安裝。而安裝libgsasl需要添加一個包含libgsasl庫的源：新建/etc/yum.repos.d/fedora.repo文件，添加如下內容：
[epel-repo]
name=epel
baseurl=http://dl.fedoraproject.org/pub/epel/6/x86_64/
enabled=1
gpgcheck=0
執行安裝：
yum install gcc gcc-c++ -y
yum install protobuf -y
yum install net-snmp-libs -y
yum install boost -y
yum install libgsasl-devel -y
C)下載安裝thrift 0.9.1
wget http://dl.fedoraproject.org/pub/epel/7/x86_64/Packages/t/thrift-0.9.1-15.el7.x86_64.rpm
rpm -ivh thrift-0.9.1-15.el7.x86_64.rpm
二、 下載安裝包apache-hawq-rpm-2.3.0.0-incubating.tar.gz，並解壓縮
cd Downloads
wget http://mirrors.tuna.tsinghua.edu.cn/apache/incubator/hawq/2.3.0.0-incubating/apache-hawq-rpm-2.3.0.0-incubating.tar.gz
tar -zxvf apache-hawq-rpm-2.3.0.0-incubating.tar.gz
三、 安裝服務端
1， 安裝
rpm -ivh --prefix=/opt/gpadmin apache-hawq-2.3.0.0-el7.x86_64.rpm
**移除安裝
yum remove apache-hawq -y
2 HAWQ的參數配置
配置HAWQ的集羣及其它參數
cd /usr/hawq/etc
vi hawq-site.xml
# 修改如下參數
參數名 值
hadoop.security.authentication simple
hawq_master_address_host ep-bd01
hawq_dfs_url ep-bd01:8020/hawq
hawq_rm_memory_limit_perseg 64GB
hawq_rm_yarn_address ep-bd01:8032
hawq_dfs_url ep-bd01:8020/hawq
hawq_global_rm_type yarn
hawq_rm_yarn_scheduler_address ep-bd01:8030
hawq_acl_type standalone
hawq_master_directory /opt/gpadmin/data/masterdd
hawq_segment_directory /opt/gpadmin/data/segmentdd
vi yarn-site.xml
# 修改如下參數
參數名 值
hadoop.security.authentication simple
2， 建立dfs/hawq
sudo -u hdfs hdfs dfs -mkdir /hawq
sudo -u hdfs hdfs dfs -chown gpadmin:gpadmin /hawq
3， 建立data目錄
sudo -u gpadmin mkdir -p /opt/gpadmin/data/masterdd /opt/gpadmin/data/segmentdd
4， 複製文件到其他節點
su - gpadmin
scp -r /opt/gpadmin/apache-hawq ep-bd[02-05]:/opt/gpadmin/.
或者，複製安裝包到其他節點，直接rpm安裝
5，初始化cluster【注意，這裏必須進入/opt/gpadmin/apache-hawq/bin】
su - gpadmin
cd /opt/gpadmin/apache-hawq/bin
source ../greenplum_path.sh
./hawq init cluster
# 初始化cluster失敗，調整之後，再次執行初始化之前需要
#刪除dfs目錄中內容：
sudo -u hdfs hdfs dfs -rm -r -f /hawq/*
#刪除數據目錄中內容
ssh ep-bd01 rm -rf /opt/gpadmin/data/masterdd/*
ssh ep-bd02 rm -rf /opt/gpadmin/data/masterdd/*
ssh ep-bd03 rm -rf /opt/gpadmin/data/masterdd/*
ssh ep-bd04 rm -rf /opt/gpadmin/data/masterdd/*
ssh ep-bd05 rm -rf /opt/gpadmin/data/masterdd/*
# 啓動停止重啓hawq
hawq stop/restart/start cluster
四、 結論，目前實驗結果，再CDH5.15.0 + clouderaManager上，HAWQ2.3.0安裝失敗，遇到的錯誤是：
