[英]django boto3: NoCredentialsError — Unable to locate credentials
[英]NoCredentialsError : Unable to locate credentials - python module boto3
我在python
虛擬環境( virtualenv
)中運行django
。 django
網站由來自亞馬遜 ec2 實例(ubuntu 16.04)的apache2
提供服務。 我使用boto3
模塊寫入亞馬遜 s3。
我安裝了awscli
並運行了aws configure
並正確設置了我的 aws 訪問密鑰。 (我知道我配置正確,因為$ aws s3 ls
返回我的 s3 存儲桶的正確列表。)
但是,當我嘗試從 django 應用程序向 s3 寫入一些對象時,它無法產生標題中所述的錯誤。
我最近搬到了一個新實例並開始使用 python 虛擬環境。 在此之前,它曾經運行良好。 我已經閱讀了關於 SO 的問題和來自 aws 的文檔。 下面是堆棧跟蹤。

我想出了我收到錯誤的原因。 我發布答案以防萬一其他人遇到此問題。
tl;dr:aws 配置文件不在 apache 的主目錄中
django 應用程序在用戶 www-data(apache2) 下運行。 當我使用aws configure
配置我的憑據時,我的設置存儲在.aws/config
文件中。
.aws/configure
文件存儲在我的主目錄中,而不是在www-data (apache2) 的主目錄中,默認情況下是/var/www
。 因此,當 django 應用程序調用 boto3 模塊時,該模塊正在/var/www/.aws/config
查找配置文件,但我的文件在/home/ubuntu/.aws/config
。
只需將相關文件復制到/var/www/
為我解決問題。
