非root安装docker

添加docker组

cat /etc/group |grep docker
sudo groupadd docker
sudo gpasswd -a 用户名 docker

下载docker源码

https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/static/stable/x86_64/docker-18.09.0.tgz

解压缩

tar -zxvf docker-18.09.0.tgz
sudo cp docker/* /usr/bin/
#docker有关指令的所属用户和所属组(必做,不然非root用户使用docker指令报错:权限不够)
sudo chown root:docker /usr/bin/docker*
sudo chown root:docker /usr/bin/containerd*
sudo chown root:docker /usr/bin/runc
sudo chown root:docker /usr/bin/ctr
