# 一、安装

  有两种安装方法，脚本安装和 apt 安装

## 1、脚本安装

  root 下执行以下命令(非 root 下会要求输入密码）：

```bash
wget -qO- https://get.docker.com/ | sh
```

等待执行完毕后会有如下提示：

```
    If you would like to use Docker as a non-root user, you should now consider
    adding your user to the "docker" group with something like:

    sudo usermod -aG docker 用户名
   Remember that you will have to log out and back in for this to take effect!
```

就是如果要以非 root 用户直接运行 docker 时需要执行`sudo usermod -aG docker 非root用户名`,然后重新登陆即可。

## 2、apt 安装

&emsp;&emsp;直接运行(root 下)

```bash
apt-get update
apt-get install docker.io
```

# 二、配置国内源

&emsp;&emsp;国外源太慢配置为国内源。修改或创建`/etc/docker/daemon.json`,内容如下：

```json
{
  "registry-mirrors": ["加速地址"],
  "insecure-registries": []
}
```

以下是国内加速地址：

- 网易 [http://hub-mirror.c.163.com](http://hub-mirror.c.163.com)
- ustc [https://docker.mirrors.ustc.edu.cn](https://docker.mirrors.ustc.edu.cn)

然后重启生效

```bash
sudo systemctl daemon-reload
sudo systemctl restart docker
```
