1. 将自己的域名解析道服务器A上

2. Install Certbot

登录到服务器 A

$ sudo apt-get update

$ sudo apt-get install certbot 
$ certbot --version //验证是否安装成功

3. 制作证书

如果443端口开着，需要先关闭

certbot certonly    --------> 开启命令

看到 ** Congratulations** 就表示制作成功，相关证书可以在/etc/letsencrypt/live/you.domain.com/下查看，

4. 配置 nginx server

server {
        listen 80;
        listen 443 ssl;
        server_name jenkins.dev.school.thoughtworks.cn;
        location / {
                proxy_pass http://localhost:8080/;
                proxy_set_header Host $http_host;
        }
 ssl_certificate /etc/letsencrypt/live/you.domain.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/you.domain.com/privkey.pem; # managed by Certbot
    ssl_session_cache shared:le_nginx_SSL:1m; # managed by Certbot
    ssl_session_timeout 1440m; # managed by Certbot

    ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # managed by Certbot
    ssl_prefer_server_ciphers on; # managed by Certbot

    ssl_ciphers "ECDHE-ECDSA-AES128-GCM-SHA256 ECDHE-ECDSA-AES256-GCM-SHA384 ECDHE-ECDSA-AES128-SHA ECDHE-ECDSA-AES256-SHA ECDHE-ECDSA-AES128-SHA256 ECDHE-ECDSA-AES256-SHA384 ECDHE-RSA-AES128-GCM-SHA256 ECDHE-RSA-AES256-GCM-SHA384 ECDHE-RSA-AES128-SHA ECDHE-RSA-AES128-SHA256 ECDHE-RSA-AES256-SHA384 DHE-RSA-AES128-GCM-SHA256 DHE-RSA-AES256-GCM-SHA384 DHE-RSA-AES128-SHA DHE-RSA-AES256-SHA DHE-RSA-AES128-SHA256 DHE-RSA-AES256-SHA256 EDH-RSA-DES-CBC3-SHA"; # managed by Certbot


    if ($scheme != "https") {
        return 301 https://$server_name$request_uri;
    } # managed by Certbot
}

5. 定时续期证书

crontab -e

添加：0 3 */7 * * /bin/certbot renew --renew-hook "/etc/init.d/nginx reload" 
每隔 7 天，夜里 3 点整自动执行检查续期命令一次。续期完成后，重启 nginx 服务

sudo service cron restart
