Linux下Docker安装配置

1.CentOS

服务器的系统是CentOS7.4的

[root@VM_82_178_centos ~]# cat /etc/RedHat-release

CentOS Linux release 7.4.1708 (Core)

#安装依赖包

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

#增加Docker软件包源

yum-config-manager \

–add-repo \

https://download.docker.com/linux/centos/docker-ce.repo

#安装Docker CE

yum install docker-ce -y

#启动

systemctl start docker

#开机启动

systemctl enable docker

#查看Docker信息

docker info

2.Ubuntu 上安装

apt-get update

安装证书：

apt-get install \

apt-transport-https \

ca-certificates \

curl \

software-properties-common

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add –

增加docker源的key：

sudo apt-key fingerprint 0EBFCD88

pub 4096R/0EBFCD88 2017-02-22

Key fingerprint = 9DC8 5822 9FC7 DD38 854A E2D8 8D81 803C 0EBF CD88

uid Docker Release (CE deb)

sub 4096R/F273FCD8 2017-02-22

增加docker软件包源：

sudo add-apt-repository \

“deb [arch=amd64] https://download.docker.com/linux/ubuntu \

$(lsb_release -cs) \

stable”

跟新apt包索引：

sudo apt-get update

安装docker ce

apt-get install docker-ce

3.配置Docker加速器

Docker Hub 提供众多镜像，你可以从中自由下载数十万计的免费应使用镜像， 这些镜像作为 docker 生态圈的基石，是我们用和学习 docker 不可或者缺的资源。为理解决国内使用户用 Docker Hub 时遇到的稳固性及速度问题 DaoCloud 推出永久免费的新一代加速器服务。

Linux：

curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://bc437cce.m.daocloud.io

[root@localhost ~]# curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://bc437cce.m.daocloud.io

docker version >= 1.12

{“registry-mirrors”: [“http://bc437cce.m.daocloud.io”]}

Success.

You need to restart docker to take effect: sudo systemctl restart docker

[root@localhost ~]#

[root@localhost ~]# systemctl restart docker

[root@localhost ~]# systemctl stop docker

[root@localhost ~]# ps -ef|grep docker

root 15185 3300 0 01:39 pts/1 00:00:00 grep –color=auto docker

[root@localhost ~]# systemctl start docker

[root@localhost ~]# ps -ef|grep docker

root 15191 1 2 01:39 ? 00:00:00 /usr/bin/dockerd

root 15198 15191 0 01:39 ? 00:00:00 docker-containerd –config /var/run/docker/containerd/containerd.toml

root 15325 3300 0 01:39 pts/1 00:00:00 grep –color=auto docker
