flask和vue前后端分离项目部署的示例代码

前段时间开发了一个项目, 我后端用的是flask框架写接口,前端用的是vue框架,项目前后端完全分离,部署的时候遇到一点问题,记录一下.

部署环境:centos6.5、Python3.6.3 、flask0.12.0 vue

部署方式:uwsgi+nginx

步骤:

​ 1.首先安装python运行环境,正常
​ 2.安装uswsgi运行,正常(使用pip安装,pip install uwsgi):

新建config.ini文件

[uwsgi]

# uwsgi 启动时所使用的地址与端口,nginx代理的时候需要转发到该地址
socket = x.x.x.x:xxxx    
#python环境目录 
#home = /usr/local/python/bin
#指向网站根目录
chdir = /root/www
#python项目启动程序文件
wsgi-file = /root/www/run.py
#python程序内用于启动的application变量名
callable = app
#处理器数
processes = 3
#线程数
threads = 3
#状态监测地址
stats = 127.0.0.1:5000
#设置uwsgi包解析的内部缓存区大小。默认4k
buffer-size = 32768

uwsgi启动命令:

uwsgi config.ini   #该命令直接启动
uwsgi -d --ini config.ini  #该命令后台运行,常用

3.安装nginx,正常,我们是运维安装的,过程不表,请百度一下

问题来了:

​ 我们在同时代理vue和flask 的时候,不管怎么折腾,前端都无法访问到flask的地址

解决办法:

​ 使用了两个不同 的域名分别代理了vue和flask,vue指向flask的代理域名
