①. 快速安装docker

①. 官网中文安装参考手册

(https://docs.docker-cn.com/engine/installation/linux/docker-

ce/centos/#prerequisites)

②. 确定你是CentOS7及以上版本(cat /etc/redhat-release)

③. yum安装gcc相关

yum -y install gcc

yum -y install gcc-c++

④. 卸载旧版本

sudo yum remove docker*

yum -y remove docker docker-common docker-selinux docker-engine
# 2018.3官网版本
yum remove docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-selinux \
                  docker-engine-selinux \
                  docker-engine

⑤. 安装需要的软件包 (yum install -y yum-utils device-mapper-persistent-data lvm2)

⑥. 设置stable镜像仓库

# 大坑:如下的可能会报错
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
# 推荐
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

⑦. 更新yum软件包索引(yum makecache fast)
⑧. 安装DOCKER CE(yum -y install docker-ce)
⑨. 启动docker

systemctl start docker

⑩. 测试

docker version
docker run hello-world

⑩①. 配置镜像加速

(注意:daemon.json是docker的核心文件)

mkdir -p /etc/docker

sudo tee /etc/docker/daemon.json <<-'EOF'
# 自己的阿里云镜像
{
  "registry-mirrors": ["https://opvvjpc5.mirror.aliyuncs.com"]
}
EOF
 #网易云
{"registry-mirrors": ["http://hub-mirror.c.163.com"] }
 
 #阿里云
{
  "registry-mirrors": ["https://｛自已的编码｝.mirror.aliyuncs.com"]
}
{
  "registry-mirrors": ["https://opvvjpc5.mirror.aliyuncs.com"]
}

systemctl daemon-reload
systemctl restart docker
