CentOS 7（Linux）安装Docker，执行yum install docker-io -y报错

一、执行yum install docker-io -y报错

Error: docker-ce conflicts with 2:docker-1.13.1-209.git7d71120.el7.centos.x86_64
       Error: docker-ce-cli conflicts with 2:docker-1.13.1-209.git7d71120.el7.centos.x86_64
       You could try using --skip-broken to work around the problem
       You could try running: rpm -Va --nofiles --nodigest

原因：CentOS 7原有的docker-ce、docker-ce-cli与当前安装的Docker版本冲突

二、尝试删除冲突包

分别执行如下命令删除冲突包：

sudo yum -y remove docker-ce

sudo yum -y remove docker-ce-cli

删除冲突包后，执行yum install docker-io -y命令，提示Complete！
