一次nginx配置经历

做题记录了新服务器postgres的安装及访问相关的问题及解决方案。 昨天晚上遇到api接口及前端没发访问的问题。 解决方案：

1. 首先需要开通443及80等端口（ubuntu默认是不开启状态）
2. 因为项目前后端及API都在一个域名+二级目录部署，所以我再把nginx配置也加到下面。

server {
      listen       443 ssl;
      server_name  aa.com;
      ssl_certificate "/root/cert/aa.com.pem";
      ssl_certificate_key "/root/cert/aa.com.key";

    }

      }
