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。
我遵循了here指令。我的Linode服务器上有一个Flask App,位于/var/www/html/hxueh.net/finance。在 finance 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>
我在同一台服务器上运行了一个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中显示:

更新:问题已解决。
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帮我部署了我的第一个网络应用程序。
答案 0 :(得分:1)
你有:
WSGIProcessGroup finance
告诉mod_wsgi将请求发送到在守护程序进程组中运行但尚未配置守护进程组的WSGI应用程序。
在WSGIScriptAlias
指令之前添加:
WSGIDaemonProcess finance
同时阅读:
了解有关守护进程组的更多信息。
BTW,mod_wsgi 4.3.0的版本很老了。你应该避免在Debian / Ubuntu上为mod_wsgi使用系统提供的软件包,因为它们通常是过时的并且也是不受支持的。建议您使用pip
安装方法自行卸载系统软件包并从源代码安装。参见:
