一、系统环境
1、系统：Ubuntu 16.04.2 LTS
2、WEB服务器：Openresty11.2.5
二、开始配置
1、获取certbot客户端
2、停止Nginx服务
3、生成证书
当前网站有多个域名时需在后面增加，例如：
./certbot-auto certonly –standalone –email `你的邮箱地址` -d `你的域名1` -d `你的域名2`
可能会出现错误1：OSError: Command /opt/eff.org/certbot/venv/bin/python2.7 – setuptools pkg_resources pip wheel failed with error code 2
解决办法：
可能会出现错误2：
解决：说明你的Nginx服务还在运行啊！赶紧的kill掉啊
成功生成证书的输出结果：
4、查看生产的证书
5、编辑Nginx配置文件和开启SSL服务
配置虚拟主机
6、重启Nginx服务
7、Let’s Encrypt 生成的免费证书为3个月时间，使用Crontab可以无限次续签证书
遇到的坑，查边所有的地方都不能够解决，最后是内存不够用的问题？
如何解决：
最后记得释放掉分配的交换分区
