运行烧瓶应用时,Apache2的error.log
显示无法找到flask_bootstrap
模块:
[wsgi:warn] mod_wsgi: Compiled for Python/2.7.11.
[wsgi:warn] mod_wsgi: Runtime using Python/2.7.12.
[mpm_event:notice] AH00489: Apache/2.4.18 (Ubuntu) mod_wsgi/4.3.0 Python/2.7.12 configured -- resuming normal operations
[core:notice] AH00094: Command line: '/usr/sbin/apache2'
[wsgi:error] mod_wsgi (pid=18587): Target WSGI script '/var/www/myapp/myapp.wsgi' cannot be loaded as Python module.
[wsgi:error] mod_wsgi (pid=18587): Exception occurred processing WSGI script '/var/www/myapp/myapp.wsgi'.
[wsgi:error] Traceback (most recent call last):

[wsgi:error] File "/var/www/myapp/myapp/__init__.py", line 2, in <module>
[wsgi:error] from flask_bootstrap import Bootstrap
[wsgi:error] ImportError: No module named flask_bootstrap
我已根据venv
myapp.conf
<VirtualHost *:80>
ServerName yourdomain.com
ServerAdmin youemail@email.com
WSGIProcessGroup myapp
WSGIApplicationGroup %{GLOBAL}
WSGIScriptAlias / /var/www/myapp/myapp.wsgi
WSGIDaemonProcess myapp python-home=/var/www/myapp/myapp/venv
<Directory /var/www/myapp/myapp/>
Order allow,deny
Allow from all
</Directory>
ErrorLog ${APACHE_LOG_DIR}/error.log
LogLevel warn
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
该模块可在系统范围内和在venv中使用:
root@host:/var/www/myapp# python
Python 2.7.12 (default, Dec 4 2017, 14:50:18)
[GCC 5.4.0 20160609] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from flask_bootstrap import Bootstrap
>>> Bootstrap
<class 'flask_bootstrap.Bootstrap'>
和...
root@host:/var/www/myapp# source myapp/venv/bin/activate
(venv) root@host:/var/www/myapp# python
Python 2.7.12 (default, Dec 4 2017, 14:50:18)
[GCC 5.4.0 20160609] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from flask_bootstrap import Bootstrap
>>> Bootstrap
<class 'flask_bootstrap.Bootstrap'>
我注意到有关于2.7.11与2.7.12不匹配的警告,但是次要版本真的是问题吗?
修改1
根据the docs,将以下内容添加到myapp.wsgi
activate_this = '/var/www/myapp/myapp/venv/bin/activate_this.py'
execfile(activate_this, dict(__file__=activate_this))
没有任何区别。
答案 0 :(得分:1)
所以,在格雷厄姆说服我之后,我的“修复”(将这两行移到<Directory>
指令中)并不是真正的修复,可能是其他错误的标志,我决定深入挖掘。
根据文档,特别是confirming the location of the virtual environment,我惊讶地发现在我的本地盒子上激活虚拟环境时(不是通过wsgi应用程序):
sys.prefix = '/usr'
当我预料到的时候:
sys.prefix = '/var/www/myapp/myapp/venv'
我不知道这是怎么发生的。也许是以root
完成所有初始工作的结果。
然而,很高兴地说,删除和重新构建虚拟环境,这次作为普通用户,一切似乎都很好。
答案 1 :(得分:0)
事实证明问题在于两行:
WSGIProcessGroup myapp
WSGIApplicationGroup %{GLOBAL}
应该在<Directory>
!
所以,myapp.conf
现在看起来像这样:
<VirtualHost *:80>
ServerName yourdomain.com
WSGIDaemonProcess myapp python-home=/var/www/myapp/myapp/venv
WSGIScriptAlias / /var/www/myapp/myapp.wsgi
<Directory /var/www/myapp/myapp>
WSGIProcessGroup myapp
WSGIApplicationGroup %{GLOBAL}
Order deny,allow
Allow from all
</Directory>
ErrorLog ${APACHE_LOG_DIR}/error.log
LogLevel warn
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
公平地说,这是the docs中的例子。
非常感谢所有评论的人:)
