我正在使用进程4的uwsgi线程模式运行Flask,还使用pymongo flask_mongoengine和uwsgi说“ MongoClient在fork之前打开。仅创建MongoClient” 我尝试用connect = False连接,但结果相同
lazy-apps = true问题已解决,但似乎uwsgi需要更多时间来加载 怎样才能获得最佳性能?

app.config ['MONGODB_SETTINGS'] = {'DB':'somedb',“ USERNAME”: “ dbadmin”,“ PASSWORD”:“ somepass”,“ connect”:False}
和
client = MongoClient(connect = False,username ='dbadmin', password ='somepass',authSource ='somedb')
Mongoengine和pymongo的解决方案

如果您使用appllication factory pattern,则设置 MongoClient connection=False
应该可以解决。它适用于我的烧瓶应用(v1.0.2),在uwsgi server(v2.0.18)之后运行。
# __init__.py
from flask_mongoengine import MongoEngine
mongo = MongoEngine()
def create_app(config=None):
app = Flask(__name__)
app.config['MONGODB_HOST'] = 'localhost'
app.config['MONGODB_PORT'] = 27017
app.config['MONGODB_DB'] = 'datazzilla'
# NOTE: This fixes "UserWarning: MongoClient opened before fork."
# I'm not aware of side effects yet. Default value is/was "True"
app.config['MONGODB_CONNECT'] = False
mongo.init_app(app)
return app
