certbot--ubuntu16.04

官网网址:https://certbot.eff.org/
在页面上选择相应的版本和工具

这里的环境是ubuntu16.04和nginx

1.先ssh到服务器中

2.安装certbot的需要的环境

sudo apt-get update
sudo apt-get install software-properties-common
sudo add-apt-repository universe
sudo add-apt-repository ppa:certbot/certbot
sudo apt-get update

3.安装certbot

sudo apt-get install certbot python-certbot-nginx

4,下载基于nginx的certbot证书

sudo certbot --nginx

第一次运行时候会有很多步骤
1.填写email
2.选择domain name(域名)或填写域名
3.是否可以通过email发送消息给你
4.输入webroot
5.记不清了

成功后会在/etc/letsencrypt/live/下面生成以你域名命名的文件夹,里面有你的证书文件

5.配置到nginx里面

server {
        server_name your_domain_name;
    location /media/ {
        alias /data/media/;
    }
        location /static/ {
            alias /home/name/project/project/static/;
        }
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
        listen 443 ssl; # managed by Certbot
        ssl_certificate  /etc/letsencrypt/live/your_domain_name/fullchain.pem;
        ssl_certificate_key /etc/letsencrypt/live/your_domain_name/privkey.pem;
        include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
        ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
}
server {
    if ($host = your_domain_name) {
        return 301 https://$host$request_uri;
    } # managed by Certbot
    listen 80;
    server_name  your_domain_name;
    return 404; # managed by Certbot
}
