python – 为什么我有错误“地址已经在使用”？

我运行我的烧瓶应用程序,它运行良好,但到应用程序停止时和我的uwsgi日志

probably another instance of uWsgi is running on the same address (127.0.0.1:9002).
    bind(): Address already in use [core/socket.c line 764]

当我运行触摸touch_reload时,应用程序再次运行.
我在服务器上运行其他任何可能接受套接字的东西.

我的conf：

Nginx
server {
    listen 80;
    ....
    location / {
       include uwsgi_params;
       uwsgi_pass 127.0.0.1:9001;
    }
    ....
}
server {
    listen 80;
    ....
    location / {
       include uwsgi_params;
       uwsgi_pass 127.0.0.1:9003;
    }
    ....
}

uwsgi:
chdir = /var/www/../
module = wsgihandler
socket = 127.0.0.1:9003
wsgi-file = app/__init__.py
callable = app
master = true
chmod-socket = 664
uid = root
gid = root
processes = 4
socket-timeout = 180
post-buffering = 8192
max-requests = 1000
buffer-size = 32768
logto = /var/www/.../log/uwsgi.log
touch-reload = /var/www/.../touch_reload

解决方法:

我有同样的问题,但问题是在sqlalchemy,尝试添加这个：

@app.teardown_request
def shutdown_session(exception=None):
    from extension import db
    db.session.remove()
