CentOS安装docker

1.卸载旧版本

yum remove docker \
                     docker-client \
                     docker-client-latest \
                     docker-common \
                     docker-latest \
                     docker-latest-logrotate \
                     docker-logrotate \
                     docker-engine

2.安装必要工具

yum install -y yum-utils \
                      device-mapper-persistent-data \
                      lvm2

3.配置docker仓库

yum-config-manager \
    --add-repo \
    https://download.docker.com/linux/centos/docker-ce.repo

4.安装docker

yum install docker-ce

5.启动docker

systemctl start docker

6.设置开机启动

systemctl enable docker

7.设置阿里云镜像加速

sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

8.配置镜像加速器
针对Docker客户端版本大于 1.10.0 的用户
您可以通过修改daemon配置文件/etc/docker/daemon.json来使用加速器

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://8z1gmdrv.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker
