Linux安装docker报错（rpm -Va –nofiles –nodigest）

1、报错信息

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

2、报错原因：之前系统安装过docker，可能导致版本冲突

3、解决方法：卸载后重装

查询安装过的包

yum list installed | grep docker

删除安装的软件包

yum -y remove docker-ce-cli.x86_64
yum -y remove containerd.io.x86_64

删除镜像/容器等

rm -rf /var/lib/docker
rm -rf /var/run/docker

重新安装即可

 yum -y install docker
