折腾:

[记录]尝试去在CentOS中折腾uwsgi

期间,对于app是:

(SIPEvents)  SIPEvents cat app.py
from flask import Flask
app = Flask(__name__)
@app.route(“/”)
def hello():
    return “Hello World!”
if __name__ == “__main__”:
    app.run(host=’0.0.0.0′, port=8080)

运行出错:

(SIPEvents)  SIPEvents flask run –host=0.0.0.0 –port=8080
 * Serving Flask app “app”
 * Forcing debug mode on

socket.error: [Errno 98] Address already in use

感觉是:

此处uwsgi占用了端口?

所以无法使用。

[已解决]如何杀掉在后台运行的uwsgi的进程

然后就可以解决此问题了。

不过又出现其它问题:

[已解决]Flask运行出错:socket.gaierror Errno -2 Name or service not known
