在国产芯片服务器上构建postgresql-xl的大数据平台
基于海之舟大数据平台服务器，操作系统，使用二台设备构建。
端口、ip配置见下表
大数据软件postgresql-xl，ssh软件操作系统已自带，用户zs(操作系统已创建）,工作目录/home/zs/
1.以下操作二台服务器均需配置
su zs
nano /etc/hosts //编辑文件，加入以下行
192.168.1.125 gtm
192.168.1.125 coordinator1
192.168.1.125 datanode1
192.168.1.8 coordinator2
192.168.1.8 datanode2
vi .bashrc //配置环境变量
export PGHOME=/usr/local/pgxl10
export LD_LIBRARY_PATH= P G H O M E / l i b : PGHOME/lib: PGHOME/lib:LD_LIBRARY_PATH
export PATH= P G H O M E / b i n : PGHOME/bin: PGHOME/bin:PATH
export dataDirRoot=$HOME/data
su root //重启服务器，使配置生效
reboot
2.在gtm上操作
2.1设置ssh 二台设备无密码登陆
su zs
ssh-keygen -t rsa
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
chmod 600 ~/.ssh/authorized_keys
ssh zs@datanode1 mkdir -p .ssh
cat .ssh/id_rsa.pub | ssh zs@datanode1 ‘cat >> .ssh/authorized_keys’
ssh zs@datanode2 mkdir -p .ssh
cat .ssh/id_rsa.pub | ssh zs@datanode2 ‘cat >> .ssh/authorized_keys’
以上操作，提问全部回车。
2.2 建立大数据库
