apache2 未在本地服务器上显示 Flask 应用程序

Question

我正在关注本教程：https : //pythonprogramming.net/creating-first-flask-web-app/?completed=/flask-web-development-introduction/

在我的本地服务器上（本地网络上的家用机器）。Flask 本身正常启动

>>> python /var/www/FlaskApp/FlaskApp/__init__.py 
* Running on http://0.0.0.0:5000/ (Press CTRL+C to quit)
127.0.0.1 - - [31/Oct/2016 22:56:29] "GET / HTTP/1.1" 200 -
127.0.0.1 - - [31/Oct/2016 22:56:29] "GET /favicon.ico HTTP/1.1" 404 -

Flask 启动 但是无论如何 Apache 都会显示其默认网页。

须藤 a2enmod wsgi

Module wsgi already enabled

cat /var/www/FlaskApp/FlaskApp/ init .py

from flask import Flask
app = Flask(__name__)
@app.route('/')
def homepage():
    return "Hi There, how you're doin?"
if __name__ == "__main__":
    app.run()(debug=True)

cat /etc/apache2/sites-available/FlaskApp.conf

<VirtualHost *>
                ServerName dagzserv
                ServerAdmin my@email.com
                WSGIScriptAlias / /var/www/FlaskApp/flaskapp.wsgi
                <Directory /var/www/FlaskApp/FlaskApp/>
            Require all granted
                </Directory>
                Alias /static /var/www/FlaskApp/FlaskApp/static
                <Directory /var/www/FlaskApp/FlaskApp/static/>
            Require all granted
                </Directory>
                ErrorLog ${APACHE_LOG_DIR}/error.log
                LogLevel warn
                CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

sudo a2ensite FlaskApp

Site FlaskApp already enabled

我尝试添加 app.run(host='0.0.0.0', port=5000) 我确实有 /etc/hosts dagserv 作为我在本地网络 (10.0.1.xxx) 中的 ip 也尝试将 ServerName 作为本地主机。

我不明白的一件事是 Apache 究竟是如何找到“FlaskApp.conf”的，但我认为它正在扫描其配置目录（/etc/apache2/sites-available/FlaskApp.conf）

我在 /var/logs/apache2 中没有收到错误

Answer 1

1. Apache 如何找到“FlaskApp.conf”

有一行/etc/apache2/apache2.conf包含虚拟主机配置：

# Include the virtual host configurations:
IncludeOptional sites-enabled/*.conf

Apache2 服务器将加载apache2.conf并包括虚拟主机配置。

2. 为什么 Apache 无论如何都显示其默认网页。

如果您通过 IP 地址访问服务器，Apache 将根据其默认站点配置返回/etc/sites-available/000-default.conf. 所以如果你想通过 IP 地址访问你的 WSGI 服务器，你应该先禁用 Apache 默认站点配置：

sudo a2dissite 000-default.conf
service apache2 restart
