Ubuntu apt安装nginx

以下是官方给出的 nginx 安装步骤，详情可参考这里

安装依赖程序

apt install curl gnupg2 ca-certificates lsb-release -y

导入stable nginx 安装源

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

设置安装源倾向性

echo -e "Package: *\nPin: origin nginx.org\nPin: release o=nginx\nPin-Priority: 900\n" \
    | sudo tee /etc/apt/preferences.d/99nginx

导入nginx官方签名

curl -o /tmp/nginx_signing.key https://nginx.org/keys/nginx_signing.key

验证下载的文件是否包含正确的密钥

gpg --dry-run --quiet --import --import-options show-only /tmp/nginx_signing.key

输出如下指纹信息则正确：573BFD6B3D8FBC641079A6ABABF5BD827BD9BF62

pub   rsa2048 2011-08-19 [SC] [expires: 2024-06-14]
      573BFD6B3D8FBC641079A6ABABF5BD827BD9BF62
uid                      nginx signing key <signing-key@nginx.com>

最后，将密钥移动到 apt 可信密钥存储（注意“asc”文件扩展名更改）：

mv /tmp/nginx_signing.key /etc/apt/trusted.gpg.d/nginx_signing.asc
