Python Apache Flask错误13,权限被拒绝
我第一次在AWS上使用Apache部署了一个Flask应用程序。HTML页面加载,但是像上传文件、写入文件和读取文件这样的事情似乎不起作用。在下面的示例中,我调用了这个特定函数,该函数写入从URL接收的数据。但是在这里,我禁用了它,代码只需要读取已经存在的文件。所以,export_po_list.xml已经存在了,我已经从终端检查过了。同样的代码在我的PC中本地运行良好 正在检查/var/log/apache2/error.log 我使用chmod 777-R对包含这个flask应用程序的整个文件夹进行了修改。它仍然不起作用Python Apache Flask错误13,权限被拒绝,python,apache,amazon-web-services,flask,Python,Apache,Amazon Web Services,Flask,我第一次在AWS上使用Apache部署了一个Flask应用程序。HTML页面加载,但是像上传文件、写入文件和读取文件这样的事情似乎不起作用。在下面的示例中,我调用了这个特定函数,该函数写入从URL接收的数据。但是在这里,我禁用了它,代码只需要读取已经存在的文件。所以,export_po_list.xml已经存在了,我已经从终端检查过了。同样的代码在我的PC中本地运行良好 正在检查/var/log/apache2/error.log 我使用chmod 777-R对包含这个flask应用程序的整个文

不要为文件使用相对路径名,您需要计算绝对路径并确保该位置为可写目录。这是必要的,因为Apache的当前工作目录通常是根目录,而根目录对于代码运行时的用户是不可写的 有关更多详细信息,请参阅mod_wsgi文档,网址为:
ssh
进入它并验证权限。您需要为用户提供所需的权限,并确保ps u
列出了服务器进程。再次确保您的export\u po\u list.xml
属于适当的用户并具有读取权限。这是一种什么样的部署?我的意思是EC2、BeansTalk?用户、组和mod perms都必须足够宽松。apache通常要求将该组设置为http
,os.getcwd()
打印什么?
