首先我们要安装git

apt-get update
apt-get -y install git

然后,检出Let's Encrypt的客户端源码

git clone https://github.com/letsencrypt/letsencrypt

这样,我们就成功的下载了Let's Encrypt的客户端

关闭nginx后进入Let's Encrypt目录

cd letsencrypt

运行Standalone插件

./letsencrypt-auto certonly --standalone

在你运行插件后,Let's Encrypt会进入初始化阶段,这时,你要输入一些信息,用于生成证书

多个域名用空格分割

如果你看到这样的文字,就说明生成了

    IMPORTANT NOTES:
- Congratulations! Your certificate and chain have been saved at
/etc/letsencrypt/live/example.com/fullchain.pem. Your
cert will expire on 2016-03-19. To obtain a new version of the
certificate in the future, simply run Let's Encrypt again.
- Your account credentials have been saved in your Let's Encrypt
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 Let's
Encrypt so making regular backups of this folder is ideal.

这段文字提示了证书的存放位置和过期日期
我的存放位置是 /etc/letsencrypt/live/example.com/fullchain.pem 在2016年3月19日过期
我们配置Nginx证书时的证书文件和密钥文件都在那个目录下。其中fullchain.pem包含了网站证书和根证书链

配置Nginx
修改我们的虚拟主机配置文件,在listen后面把80改成443,并加SSL,然后在下面加入我们的证书和密钥地址。

        listen 443 ssl;
ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_prefer_server_ciphers on;
ssl_ciphers AES256+EECDH:AES256+EDH:!aNULL;

然后保存,退出,重启Nginx即可!
