根据我的错误日志，我的目标WSGI脚本无法作为Python模块加载，但是在我的日志末尾，我还收到一个 ImportError：No module named foodshop.settings 。我可以验证该模块是否存在。
这是我的错误日志：

另外，这是我的apache2.conf文件：
Mutex file:${APACHE_LOCK_DIR} default PidFile ${APACHE_PID_FILE} Timeout 300 KeepAlive On MaxKeepAliveRequests 100 KeepAliveTimeout 5 # These need to be set in /etc/apache2/envvars User ${APACHE_RUN_USER} Group ${APACHE_RUN_GROUP} HostnameLookups Off ErrorLog ${APACHE_LOG_DIR}/error.log LogLevel warn IncludeOptional mods-enabled/*.load IncludeOptional mods-enabled/*.conf Include ports.conf <Directory /> Options FollowSymLinks AllowOverride None Require all denied </Directory> <Directory /usr/share> AllowOverride None Require all granted </Directory> <Directory /var/www/> Options Indexes FollowSymLinks AllowOverride None Require all granted </Directory> AccessFileName .htaccess <FilesMatch "^\.ht"> Require all denied </FilesMatch> LogFormat "%v:%p %h %l %u %t \"%r\" %>s %O \"%{Referer}i\" \"%{User-Agent}i\"" vhost_combined LogFormat "%h %l %u %t \"%r\" %>s %O \"%{Referer}i\" \"%{User-Agent}i\"" combined LogFormat "%h %l %u %t \"%r\" %>s %O" common LogFormat "%{Referer}i -> %U" referer LogFormat "%{User-agent}i" agent IncludeOptional conf-enabled/*.conf IncludeOptional sites-enabled/*.conf ServerAdmin webmaster@localhost DocumentRoot /var/www/html CustomLog ${APACHE_LOG_DIR}/access.log combined WSGIScriptAlias / /home/ubuntu/gather/src/foodshop/wsgi.py <Directory /home/ubuntu/gather/src/foodshop/> WSGIProcessGroup gather WSGIApplicationGroup %{GLOBAL} Options All AllowOverride All Require all granted </Directory> Alias /media/ /home/ubuntu/gather/src/foodshop/media/ <Directory /home/ubuntu/gather/src/foodshop/media/> Options FollowSymLinks MultiViews Order deny,allow Allow from all </Directory> Alias /static/ /home/ubuntu/gather/src/foodshop/static/ <Directory /home/ubuntu/gather/src/foodshop/static/> Options FollowSymLinks MultiViews Order allow,deny Allow from all </Directory>
和我的000-default.conf文件：
<VirtualHost *:80> ServerAdmin webmaster@localhost DocumentRoot /var/www/html ErrorLog ${APACHE_LOG_DIR}/error.log CustomLog ${APACHE_LOG_DIR}/access.log combined Alias /static /home/ubuntu/gather/static <Directory /home/ubuntu/gather/static> Require all granted </Directory> <Directory /home/ubuntu/gather/src/foodshop> <Files wsgi.py> Require all granted </Files> </Directory> WSGIDaemonProcess gather processes=2 threads=15 WSGIProcessGroup gather WSGIScriptAlias / /home/ubuntu/gather/src/foodshop/wsgi.py </VirtualHost>
最后，这是我的wsgi.py文件：
import os os.environ.setdefault("DJANGO_SETTINGS_MODULE", "foodshop.settings") from django.core.wsgi import get_wsgi_application application = get_wsgi_application()
我已连接到EC2实例（Ubuntu 14.04），并且在该实例上仅运行1个应用程序。当我在本地主机上运行它时，它可以完美运行。
您无需做任何事情即可将您的应用程序及其设置文件放置在Python路径上。
如果您不使用virtualenv（尽管应该使用），那么最简单的方法是在wsgi文件中执行以下操作：
import os, sys sys.path.append('/home/ubuntu/gather/src') os.environ.setdefault("DJANGO_SETTINGS_MODULE", "foodshop.settings")
