使用 Nginx 和 Gunicorn 部署 Django 博客出现的2个问题

Question

问题描述

服务器:阿里云ECS服务器
服务器系统:Ubuntu 16.04 64位
域名:备案ing(访问时是使用ip地址去访问服务器,所以应该和域名无关)

在初次安装好Nginx后可以使用id地址访问到 欢迎页面,
但是在配置完nginx之后出现 502 Bad Gateway

这是第一个问题,查了很多文档 都试了一下没解决

---

第二个问题:跳过页面502访问问题继续部署的时候,在部署 Gunicorn的时候输入

gunicorn --bind unix:/tmp/www.xxx.com.socket blog.wsgi:application
# 执行代码路径是在项目路径 也就是blog路径下执行的,www.xxx.com是父级路径

报错了,报错信息是:

第一次进行服务器部署,真的头有点大,恳请各位帮忙看下这2个问题是什么情况,以及如何解决,跪谢!!!

Answer 1

ImportError: No module named 'blog'是包或者模块的引用有问题，建议在项目中使用绝对导入；
另外，502 Bad Gateway应该是你的哪个配置文件有问题。部署建议参考：
How To Set Up Django with Postgres, Nginx, and Gunicorn on Ubuntu 16.04
How to Deploy a Django Application to Digital Ocean

Answer 2

你遇到的502就是因为你的程序故障导致的吧
异常也展示出来：ImportError: No module named 'blog'

Answer 3

可以参考一下我的部署记录 http://www.abb1315.com/post/9/ 希望能有帮助。
