1.安装docker
① 卸载现有的docker,这里只说明centos下的。其他方案请见:https://docs.docker.com/install/linux/docker-ce/centos
$ sudo yum remove docker \
docker-client \
docker-client-latest \
docker-common \
docker-latest \
docker-latest-logrotate \
docker-logrotate \
docker-selinux \
docker-engine-selinux \
docker-engine
② 安装相关包
sudo yum install -y yum-utils \
device-mapper-persistent-data \
lvm2
③ 设置源
sudo yum-config-manager \
--add-repo \
https://download.docker.com/linux/centos/docker-ce.repo
④ 安装最新版本的docker
sudo yum install docker-ce
⑤ 启动
sudo systemctl start docker
⑥ 验证是否成功
可以尝试运行
sudo docker run hello-world
也可以看看版本
sudo docker version
输出如下信息:
