docker搭建greenplum集群

准备环境
centos版本：CentOS Linux release 7.6.1810
docker版本：Docker version 19.03.13
greenplum版本： greenplum-db-6.4.0
greenplum下载 提取码：oumt

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
{
"registry-mirrors": ["http://hub-mirror.c.163.com","https://registry.docker-cn.com","https://docker.mirrors.ustc.edu.cn"]
} 

#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
