【问题标题】：Django - No file write in tmp - invalid syntax (connections.py, line 36)Django - tmp 中没有文件写入 - 语法无效（connections.py，第 36 行）
【发布时间】：2019-03-16 13:36:47
【问题描述】：

我将我的 django 站点放入 centos7 服务器。

我最近在 tmp 目录中上传文件时遇到了一些问题（它不起作用），所以我指定了一个 tmp 目录（参见settings.py 的最后几行）。

但我仍然阻止在此目录中写入文件的问题...

在我的开发计算机上，在上传期间，tmp file 是在 web 浏览器上传期间创建的（确实是正常的）。但是在这里，在网络浏览器上上传期间没有写入任何内容，我有这个错误。

错误

我认为发生错误是因为没有写入 tmp 文件...

如果有人可以帮助我，我会非常优雅，centos7 中的 prod env 对于新手 centos 向导来说非常奇怪。

编辑 1 - 权限 TMP 文件夹

[ME@web01 PATHTOPARENTSITE]$ ls -Z MYSITE/media/
drw-r--r--. apache apache system_u:object_r:httpd_sys_content_t:s0 tmp
drwxr-xr-x. apache apache system_u:object_r:httpd_sys_content_t:s0 work_directory

编辑 2 - 完成日志调试

【问题讨论】：

运行Django服务器的用户是否对/tmp目录有适当的权限？
什么是connections.py？错误来自该文件，与设置无关。 invalid syntax (connections.py, line 36)
@WillemVanOnsem 我编辑了表格yut问题，如果我理解你的话。
@DalinDad：看起来只有apache 可以写入目录。 import getpass; print(getpass.getuser()) 的结果是什么？这应该会打印出运行 Django 服务器的用户名。
@BurhanKhalid 我用完整的日志编辑了我的帖子。我希望它可以帮助

标签： django apache centos7

【解决方案1】：

Willem Van Onsem找到的解决方法是修改权限模式。

所以在settings.py，只需更改：

FILE_UPLOAD_PERMISSIONS = 0o644

作者：

FILE_UPLOAD_PERMISSIONS = 0o755
