CENTOS一键安装docker 经常买小鸡，每次都手动安装docker有点麻烦，所以把几条命令写成了脚本。如果是root用户运行：yum install wget -y && wget http://sh.335.im/install-docker.sh && chmod +x install-docker.sh && ./install-docker.sh如果是非root用户运行：sudo yum install wget -y && sudo wget http://sh.335.im/install-docker.sh && sudo chmod +x install-docker.sh && sudo ./install-docker.sh
