为唯一域托管多个 Flask 应用程序答案

【问题标题】：hosting multiple Flask apps for unique domains为唯一域托管多个 Flask 应用程序
【发布时间】：2018-04-16 17:53:49
【问题描述】：

我有两个独特的域（例如 domain1.com 和 domain2.com）。我正在尝试使用 Flask 在一个 linode 服务器（例如12.34.567.890）上托管两个独特的网页（通过两个单独的烧瓶应用程序）。

目前，domain1.com 有效，但domain2.com 给了我 Apache2 默认页面。

这是我目前所拥有的：

等\apache2\ports.conf：

Listen 80
Listen 8080

<IfModule ssl_module>
    Listen 443
</IfModule>

<IfModule mod_gnutls.c>
    Listen 443
</IfModule>

# vim: syntax=apache ts=4 sw=4 sts=4 sr noet

etc\apache2\sites-available\000-default.conf:

<VirtualHost *:80>
    ServerAdmin webmaster@localhost
    DocumentRoot /var/www/html
    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

<VirtualHost *:8080>
    ServerAdmin webmaster@localhost
    DocumentRoot /var/www/html
    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

etc\apache2\sites-available\FlaskApp.conf：

<VirtualHost *:80>
            ServerName domain1.com
            ServerAdmin admin@email.com
            WSGIScriptAlias / /var/www/AppOne/flaskapp.wsgi
            <Directory /var/www/AppOne/FlaskApp/>
                    Order allow,deny
                    Allow from all
            </Directory>
            Alias /static /var/www/AppOne/FlaskApp/static
            <Directory /var/www/AppOne/FlaskApp/static/>
                    Order allow,deny
                    Allow from all
            </Directory>
            ErrorLog ${APACHE_LOG_DIR}/error.log
            LogLevel warn
            CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

<VirtualHost *:8080>
            ServerName domain2.com
            ServerAdmin admin@email.com
            WSGIScriptAlias / /var/www/AppTwo/flaskapp.wsgi
            <Directory /var/www/AppTwo/FlaskApp/>
                    Order allow,deny
                    Allow from all
            </Directory>
            Alias /static /var/www/AppTwo/FlaskApp/static
            <Directory /var/www/AppTwo/FlaskApp/static/>
                    Order allow,deny
                    Allow from all
            </Directory>
            ErrorLog ${APACHE_LOG_DIR}/error.log
            LogLevel warn
            CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

__init__.py 对于每个应用程序都是相同的（但在不同的目录中）：

from flask import Flask, render_template, flash, request, url_for, redirect, session
from content_management import Content
#...etc...
import gc

TOPIC_DICT = Content()

app = Flask(__name__)

@app.route('/')
def homepage():
    return render_template("home.html")

if __name__ == "__main__":
    app.run()

\var\www\ 目录如下所示：

\var\www
|
└─── AppOne
|    |    flaskapp.wsgi
|    |
|    └─── FlaskApp
|         |  __init__.py
|         |
|         └─── static
|         └─── templates
|         |        home.html
|         |
|         └─── venv
|
└─── AppTwo                  #same as AppOne
     |    flaskapp.wsgi
     |
     └─── FlaskApp
          |  __init__.py
          |
          └─── static
          └─── templates
          |        home.html
          |
          └─── venv

对不起，如果我有点冗长，但任何指导都会有所帮助！

【解决方案1】：

无需监听 8080 端口。AppTwo 的 WSGI 文件没有指向正确的目录。

ports.conf：

Listen 80

<IfModule ssl_module>
    Listen 443
</IfModule>

<IfModule mod_gnutls.c>
    Listen 443
</IfModule>

000-default.conf：

<VirtualHost *:80>
    ServerAdmin webmaster@localhost
    DocumentRoot /var/www/html
    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

FlaskApp.conf：

<VirtualHost *:80>
        ServerName domain1.com
        ServerAdmin admin@email.com
        WSGIScriptAlias / /var/www/AppOne/flaskapp.wsgi
        <Directory /var/www/AppOne/FlaskApp/>

        </Directory>
        ErrorLog ${APACHE_LOG_DIR}/error.log
        LogLevel warn

AppOne/flaskapp.wsgi：

import sys
import logging
logging.basicConfig(stream=sys.stderr)
sys.path.insert(0,"/var/www/AppOne/")

from FlaskApp import app as application
application.secret_key = 'PasswordGoesHere'

AppTwo/flaskapp.wsgi：

import sys
import logging
logging.basicConfig(stream=sys.stderr)
sys.path.insert(0,"/var/www/AppTwo/")

from FlaskApp import app as application
application.secret_key = 'PasswordGoesHere'
