1. 先安装依赖组件

sudo apt install curl gnupg2 ca-certificates lsb-release

echo "deb http://nginx.org/packages/debian `lsb_release -cs` nginx" \
    | sudo tee /etc/apt/sources.list.d/nginx.list

3. 增加key

curl -fsSL https://nginx.org/keys/nginx_signing.key | sudo apt-key add -

4. 校验key

sudo apt-key fingerprint ABF5BD827BD9BF62
如果看到以下命令，表明成功
pub   rsa2048 2011-08-19 [SC] [expires: 2024-06-14]
