docker环境搭建

docker安装（centos）

• 添加代理

    [root@localhost ~]# export https_proxy=http://192.168.102.10:8118
    [root@localhost ~]# export http_proxy=http://192.168.102.10:8118 
  

• 安装docker repository

  根据操作系统选择需要的docker版本

  https://docs.docker.com/install/linux/docker-ce/centos/#install-docker-ce

  安装docker仓库需要的组件

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

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

  如果上面的安装不了可以换成阿里云的镜像源：

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

• 安装docker-CE(17.03.2版本)

  要先安装docker-ce-selinux-17.03.2.ce，否则安装docker-ce会报错

  yum install https://download.docker.com/
  linux/centos/7/x86_64/stable/Packages/docker-ce-selinux-17.03.2.ce-1.el7.centos.noarch.rpm
  

  sudo yum install docker-ce-17.03.2.ce-1.el7.centos
  

  如果遇到问题：Delta RPMs disabled because /usr/bin/applydeltarpm not installed.

  yum install -y deltarpm
  

• 启动docker

  设置docker开机自动启动

  sudo systemctl enable docker
  

  开启docker服务

  systemctl start docker
  

docker安装（Ubuntu）

Ubuntu的由于官方在线安装没有提供历史版本，采用离线安装模式

• 添加代理(如果有需要)

    [root@localhost ~]# export https_proxy=http://192.168.102.10:8118
    [root@localhost ~]# export http_proxy=http://192.168.102.10:8118 
  

• 安装docker(17.03.2版本)

  升级source列表（这里用国内源会比较快，替换源）

  vim /etc/apt/sources.list
  

  将该文件中的源替换为网易源（阿里源也可）

  deb http://mirrors.163.com/ubuntu/ precise main restricted universe multiverse
  deb http://mirrors.163.com/ubuntu/ precise-security main restricted universe multiverse
  deb http://mirrors.163.com/ubuntu/ precise-updates main restricted universe multiverse
  deb http://mirrors.163.com/ubuntu/ precise-proposed main restricted universe multiverse
  deb http://mirrors.163.com/ubuntu/ precise-backports main restricted universe multiverse
  deb-src http://mirrors.163.com/ubuntu/ precise main restricted universe multiverse
  deb-src http://mirrors.163.com/ubuntu/ precise-security main restricted universe multiverse
  deb-src http://mirrors.163.com/ubuntu/ precise-updates main restricted universe multiverse
  deb-src http://mirrors.163.com/ubuntu/ precise-proposed main restricted universe multiverse
  deb-src http://mirrors.163.com/ubuntu/ precise-backports main restricted universe multiverse 
  

  开始更新

  apt-get update
  

  去官方下载docker二进制文件（.deb）

  https://download.docker.com/linux/ubuntu/dists/xenial/pool/stable/amd64/
  

  下载docker所依赖的库文件（https://pkgs.org/）
  搜索：libltdl7
  下载deb：libltdl7_2.4.6-2_amd64.deb

  将这两个deb文件上传到机器的/tmp目录下，并安装deb文件

  sudo dpkg -i /tmp/libltdl7_2.4.6-0.1_amd64.deb
  sudo dpkg -i /tmp/docker-ce_17.03.2_ce-0_ubuntu-xenial_amd64.deb
  

• 启动docker

  设置docker开机自动启动

  sudo systemctl enable docker
  

  启动docker服务

  systemctl start docker
