摘要: 最受欢迎的免费HTTPS证书,了解一下?
HTTPS已成为业界标准,这篇博客将教你申请Let's Encrypt的免费HTTPS证书。
本文的操作是在Ubuntu 16.04下进行,使用nginx作为Web服务器。
1. 安装Certbot
Certbot可以用于管理(申请、更新、配置、撤销和删除等)Let's Encrypt证书。这里安装的是带nginx插件的certbot:
sudo apt-get update
sudo apt-get install software-properties-common
sudo add-apt-repository -y ppa:certbot/certbot
sudo apt-get update
sudo apt-get install -y python-certbot-nginx
2. 配置Nginx
vim /etc/nginx/conf.d/fundebug.conf
此时还没有HTTPS证书,因此域名只能使用80端口而非443端口,网站只能通过http协议而非https协议访问:http://www.fundebug.com。
server
{
listen 80;
server_name www.fundebug.com;
}
重启nginx:
systemctl restart nginx
3. 配置DNS
使域名www.fundebug.com指向nginx所在服务器的IP:

4. 申请证书
使用certbot命令为www.fundebug.com申请HTTPS证书。--nginx选项表示Web服务器为nginx,-d选项指定域名,-n选项表示非交互式运行命令。若去除-n选项,则终端会提醒你选择是否将http请求重定向为https请求。
certbot --nginx -d www.fundebug.com -n
证书申请成功之后,会看到以下信息。Let's Encrypt证书的有效期只有3个月,但是Certbot会通过Cron和systemd timer自动更新证书,证书的时效性不用担心。
IMPORTANT NOTES:
- Congratulations! Your certificate and chain have been saved at:
/etc/letsencrypt/live/www.fundebug.com/fullchain.pem
Your key file has been saved at:
/etc/letsencrypt/live/www.fundebug.com/privkey.pem
Your cert will expire on 2018-09-29. To obtain a new or tweaked
version of this certificate in the future, simply run certbot again
with the "certonly" option. To non-interactively renew *all* of
your certificates, run "certbot renew"
- If you like Certbot, please consider supporting our work by:

HTTPS证书相关的文件在/etc/letsencrypt/目录中:
find /etc/letsencrypt/ -name "*www.fundebug.com*"
/etc/letsencrypt/renewal/www.fundebug.com.conf
/etc/letsencrypt/archive/www.fundebug.com
/etc/letsencrypt/live/www.fundebug.com
certbot会自动修改nginx配置文件:
cat /etc/nginx/conf.d/fundebug.conf
nginx监听了443端口并配置了HTTPS证书,这时我们可以通过HTTPS协议访问了!https://www.fundebug.com
server
{
listen 80;
server_name www.fundebug.com;
listen 443 ssl; # managed by Certbot
ssl_certificate /etc/letsencrypt/live/www.fundebug.com/fullchain.pem; # managed by Certbot
ssl_certificate_key /etc/letsencrypt/live/www.fundebug.com/privkey.pem; # managed by Certbot
include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
}
