[python] flask + ngnix

文本记录了当使用python+flask的应用时，如何配合ngnix实现通过80端口访问，从而也就可以使用域名直接访问python app。

评论中有502错误解决方法。

如果有多个app，virtualenv可以共用，只要在service的路径里面写上实际路径即可

virtualenv webprojectenv

source webprojectenv/bin/activate

502

For those that have the 502 gateway error try changing chmod-socket = 660

uwsgi_pass unix:///home/sammy/myproject/myproject.sock;

 

假设目录为test1

运行create.sh

createsh test1
source myprojectenv/bin/activate
增加.py or template

测试是否正常

  1. uwsgi –socket 0.0.0.0:5000 –protocol=http -w wsgi:app

 

如下代码存为create.sh, 即使目录存在，也可以使用此脚本重新配置

if [ $# -ne 1 ]
then
echo “Error input, must be a project name”
exit
fi
