离线环境下安装docker
1.从docker官方下载安装包
2.内网环境中安装docker

#创建文件夹
mkdir docker 在这里插入代码片
#上传解压tar包
tar -zxvf docker-19.03.7.tgz
#将docker包下的指令移动到/usr/bin目录下
mv docker/* /usr/bin/
#配置代理，使docker可以从仓库拉镜像
mkdir /etc/systemd/system/docker.service.d
echo /etc/systemd/system/docker.service.d/http-proxy.conf
#在http-proxy.conf中配置一下内容
[Service] 
Environment="HTTP_PROXY=http://ip:port/" "HTTPS_PROXY=http://ip:port/" "NO_PROXY=localhost,127.0.0.1,×.×.×.×" 
#刷新配置，重启docker服务：
sudo systemctl daemon-reload
sudo service docker restart
#检查是否配置成功
systemctl show --property=Environment docker  #如果配置成功，执行该命令将会看到配置的代理信息
#配置国内镜像源
echo /etc/docker/daemon.json
#复制粘贴时注意json格式

} 

#查看是否配置成功：
sudo docker info

• 启动服务

#添加文件权限并启动docker
chmod +x /etc/systemd/system/docker.service 
#重载unit配置文件
systemctl daemon-reload
#启动Docker
systemctl start docker
#设置开机自启
systemctl enable docker.service

#移动到/usr/local/bin目录下并修改名称
sudo mv docker-compose-Linux-x86_64 /usr/local/bin/docker-compose
#添加可执行权限
sudo chmod +x /usr/local/bin/docker-compose
#查看是否成功
docker-compose -v

#新建greenplum文件夹
mkdir docker/greenplum
#上传greenplum安装包到greenplum文件夹下
#编辑Dockerfile文件
vi Dockerfile
#复制粘贴以下内容
FROM lyasper/gphost
COPY greenplum-db-6.4.-rhel7-x86_64.rpm /home/gpadmin/greenplum-db.rpm
RUN rpm -i /home/gpadmin/greenplum-db.rpm --nodeps --force

• 执行Dockerfile文件

docker build . -t mygreenplum

执行docker-compose

docker-compose up -d

集群配置和初始化

• 登录master节点

ssh -p 2222 gpadmin@127...1  #密码: changeme

source /usr/local/greenplum-db/greenplum_path.sh

./artifact/prepare.sh -s 2 -n 2

source env.sh
gpinitsystem -a -c gpinitsystem_config

#gpadmin超级用户无密码，登录master节点后直接执行以下命令即可登录
psql
#如果想修改gpadmin密码可执行
alter user gpadmin with password 'new password';

# 登录master节点后，执行以下命令cd /gpadmin/master/gpseg-1
vi pg_hba.conf
# 最后一行添加如下內容
host    all     all     0.0.0.0/       md5
# 修改后重启集群
gpstop -u
