仅当使用带有nginx服务器的flask restplus时,才会出现此错误。使用flask时服务器正常工作,在本地运行应用程序时,flask-restplus api工作正常,甚至是:
uwsgi --socket 0.0.0.0:5000 --protocol=http -w wsgi:application
在我的EC2实例上。
我尝试过使用gunicorn和nginx(而不是uwsgi),但我在/var/log/nginx/error.log文件中遇到了同样的错误:
2017/07/03 20:30:02 [crit] 957#957: *1 connect() to unix:/home/jamie/my_app/my_app.sock failed
(2: No such file or directory) while connecting to upstream,
client: #.#.#.#, server: #.#.#.#, request: "GET /favicon.ico HTTP/1.1", upstream:
"uwsgi://unix:/home/jamie/my_app/my_app.sock:", host: "#.#.#.#", referrer: "http://#.#.#.#/"
该应用程序通过wsgi.py来实现,如下所示:
from main import application
if __name__ == "__main__":
application.run('0.0.0.0')
main.py文件包含以下内容:
from boto3 import resource
from flask import json, request, abort
from flask import Flask
from flask_restplus import Api, Resource, fields
application = Flask(__name__)
api = Api(application)
@api.route('/users', methods=['GET', 'POST'])
class Users(Resource):
def get(self):
return users_get()
@api.expect(resource_fields)
def post(self):
return user_login()
@api.route('/users/<string:Username>', methods=['GET', 'PUT', 'DELETE'])
class User(Resource):
def get(self, Username):
return user_get(Username)
def put(self, Username):
return create_user(Username)
def delete(self, Username):
return delete_user(Username)
为了配置我跟随this digitalocean tutorial的服务器,我的配置基本相同。如果有人想看到它,我可以提供它。
我的uwsgi ini文件如下:
[uwsgi]
module = wsgi:application
master = true
processes = 5
socket = my_app.sock
chmod-socket = 666
vacuum = true
die-on-term = true
我的nginx服务器配置位于etc / nginx / sites-available / my_app 像这样:
server {
listen 80;
server_name #.#.#.#;
location / {
include uwsgi_params;
uwsgi_pass unix:/home/jamie/my_app/my_app.sock;
}
}
最后我的/etc/systemd/system/fitness_test_app.service文件是这样的:
[Unit]
Description=uWSGI instance to serve my_app
After=network.target
[Service]
User=jamie
Group=www-data
WorkingDirectory=/home/jamie/my_app
Environment="PATH=/home/jamie/my_app/myprojectenv/bin"
ExecStart=/home/jamie/my_app/myprojectenv/bin/uwsgi --ini my_app.ini
[Install]
WantedBy=multi-user.target
如果有人知道什么可能导致这个问题,我将非常感谢答案,因为我已经有一段时间无法解决这个问题了。
