IMPORTANT NOTES:
 - Congratulations! Your certificate and chain have been saved at:
   /etc/letsencrypt/live/linuxchina.net/fullchain.pem
   Your key file has been saved at:
   /etc/letsencrypt/live/linuxchina.net/privkey.pem
   Your cert will expire on 2020-02-29. To obtain a new or tweaked
   version of this certificate in the future, simply run certbot
   again. To non-interactively renew *all* of your certificates, run
   "certbot renew"
 - Your account credentials have been saved in your Certbot
   configuration directory at /etc/letsencrypt. You should make a
   secure backup of this folder now. This configuration directory will
   also contain certificates and private keys obtained by Certbot so
   making regular backups of this folder is ideal.
 - If you like Certbot, please consider supporting our work by:

==第零==
这里最了的办法了，不用再去理其它了，昨天就看了别的 搞了半天s呀 20170627

今天用了另外一个方法 20170125
<pre>pkg install py27-certbot

certbot certonly --standalone -d wiki.linuxchina.net  -d blog.linuxchina.net 
</pre>

==自动更新证书==
<pre>
#!/bin/sh
service nginx stop  && certbot renew && service nginx start

#这个是别人的写法 也是不错 
echo '0 3 * */2 * certbot renew --pre-hook "service nginx stop" --post-hook "service nginx start"' >certbot-auto-renew-cron
crontab certbot-auto-renew-cron
</pre>
说明 
--pre-hook 这个参数表示执行更新操作之前要做的事情，因为我有 --standalone 模式的证书，所以需要 停止 nginx 服务，解除端口占用。
--post-hook 这个参数表示执行更新操作完成后要做的事情，这里就恢复 nginx 服务的启用

https://certbot.eff.org/#freebsd-nginx
https://my.oschina.net/u/2328699/blog/829503

==第一==
===单域名===
 <pre> 
#这是老办法了
 git clone https://github.com/letsencrypt/letsencrypt
 cd letsencrypt
 ./letsencrypt-auto certonly --standalone --email evan886@gmail.com -d linuxchina.net  -d www.linuxchina.net  --debug </pre>
===泛域名===
<pre>#泛域名 注xxx.com请根据自己的域名自行更改  要续期的话，执行certbot-auto renew就可以了
./certbot-auto --server https://acme-v02.api.letsencrypt.org/directory  --email evan886@gmail.com -d "*.linuxchina.net" --manual --preferred-challenges dns-01 certonly
 </pre>

==第二、Let’s Encrypt免费SSL证书获取与应用==
<pre>在完成Let’s Encrypt证书的生成之后，我们会在”/etc/letsencrypt/live/yourdomain/”域名目录下有4个文件就是生成的密钥证书文件。<br/> cert.pem – Apache服务器端证书<br/> chain.pem – Apache根证书和中继证书
#我们重点的是关注这个 
fullchain.pem – Nginx所需要ssl_certificate文件
privkey.pem – 安全证书KEY文件

ssl_certificate /etc/letsencrypt/live/linuxchina.net/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/linuxchina.net/privkey.pem;

 #90天后自动更新 好像不行，有交互界面的 
 * * */90 * * /data/mon/autossl

 详细的nginx https配置文件
 #4 blog 
    server {
        listen       80;
       # listen [::]:80 ipv6only=on default_server;
        listen 443 default ssl;
       #listen [::]:80;
       #ssl on;
        ssl_certificate /etc/letsencrypt/live/linuxchina.net/fullchain.pem;
        ssl_certificate_key /etc/letsencrypt/live/linuxchina.net/privkey.pem;

       server_name  linuxchina.net www.linuxchina.net;

 #by evan
    if ($scheme = http) {
           return 301 https://$server_name$request_uri;
    } 
 #by evan
    #    server_name  blog.linuxchina.net;
        charset utf-8;
          root /data/www/evan;
        index index.php index.html index.htm;

注意:
ssl on 不要打开 ，不然会400

重新更新key  现在可以用更加简单的了 ，见文章最前面
 #/bin/sh 
 cd /data/www/ssl/letsencrypt
 #git clone https://github.com/letsencrypt/letsencrypt
 ./letsencrypt-auto certonly --renew-by-default --email evan886@gmail.com  -d linuxchina.net  -d www.linuxchina.net --debug</pre>
