在Flask设置中无法解决mod_wsgi异常

我想使用Python 3部署Flask应用程序 . 我正在运行Ubuntu 16.04，Apache2 .

我运行了sudo apt-get install libapache2-mod-wsgi-py3来安装wsgi .

我按照指令here . 我的Linode服务器上有一个Flask App，位于/var/www/html/hxueh.net/finance . 在财务文件夹中有一个文件和一个文件夹 . 结构看起来像这样 .

|--------finance
|----------------finance
|-----------------------static
|-----------------------templates
|-----------------------venv
|-----------------------application.py
|----------------finance.wsgi

在venv / bin中：

activate activate_this.py flask pip3.5 python3.5
activate.csh easy_install pip python python-config
activate.fish easy_install-3.5 pip3 python3 wheel

finance.wsgi是：

#!/usr/bin/python3
import sys
import logging
logging.basicConfig(stream=sys.stderr)
sys.path.insert(0,"/var/www/html/hxueh.net/finance/")

from finance import app as application

我的Apache2配置是：

<VirtualHost *:80>
        ServerName finance.hxueh.net
        ServerAdmin hxueh1996@gmail.com
        WSGIScriptAlias / /var/www/html/hxueh.net/finance/finance.wsgi
        <Directory /var/www/html/hxueh.net/finance/finance/>
                Order allow,deny
                Allow from all
        </Directory>
        <Directory /var/www/html/hxueh.net/finance>
                WSGIProcessGroup finance
                WSGIApplicationGroup %{GLOBAL}
                Order deny,allow
                Allow from all
        </Directory>
        Alias /static /var/www/html/hxueh.net/finance/finance/static
        <Directory /var/www/html/hxueh.net/finance/finance/static/>
                Order allow,deny
                Allow from all
        </Directory>
        ErrorLog ${APACHE_LOG_DIR}/error.log
        LogLevel warn
        CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

我有一个在同一台服务器上运行的Wordpress应用程序，Certbot启用了Let的加密证书 .

当我访问我的服务器时它返回错误500.在error.log中它显示：

[Sun Jan 21 10:40:56.310304 2018] [mpm_prefork:notice] [pid 26281] AH00169: caught SIGTERM, shutting down

UPDATE: Problem Solved.

我重写了结构并将wsgi文件放在项目中 .

|--------Finance
|----------------static
|----------------templates
|----------------venv
|----------------application.py
|----------------finance.wsgi

我也重写了Apache 2文件 . 我禁用了WSGIProcessGroup，因为我不需要它 .

<VirtualHost *:80>
        ServerName finance.hxueh.net
        ServerAdmin hxueh1996@gmail.com
        WSGIScriptAlias / /var/www/html/hxueh.net/Finance/finance.wsgi
        <Directory /var/www/html/hxueh.net/Finance/>
                Order allow,deny
                Allow from all
        </Directory>
        <Directory /var/www/html/hxueh.net/Finance>
                Order deny,allow
                Allow from all
        </Directory>
        Alias /static /var/www/html/hxueh.net/Finance/static
        <Directory /var/www/html/hxueh.net/Finance/static/>
                Order allow,deny
                Allow from all
        </Directory>
        ErrorLog ${APACHE_LOG_DIR}/error.log
        LogLevel warn
        CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

确保在/etc/apache2/mods-available/mod.load中启用mod_wsgi . 只需运行 mod_wsgi-express module-config 并将输出放入其中 . 然后运行 sudo a2enmod wsgi 和 sudo service apache2 restart .

我的finance.wsgi是：

#!/usr/bin/python3
import sys
import logging
logging.basicConfig(stream=sys.stderr)
sys.path.insert(0,"/var/www/html/hxueh.net/Finance/")

from application import app as application

最后，感谢Graham Dumpleton帮助我部署了我的第一个Web应用程序 .
