【问题描述】：

尝试在 aws elasticbeanstalk 中上传我的实例时收到以下错误：

The configuration file .ebextensions/setup.config in application version t5 contains invalid YAML or JSON. 
YAML exception: while scanning a quoted scalar in "<reader>", line 3, column 18: command: 
"aws s3 cp s3:elasticbeanstalk-u ... ^ found unexpected end of stream in "<reader>", 
line 5, column 1: ^ , JSON exception: Unexpected character (c) at position 0.. Update the configuration file.

以下是setup.config 文件中包含的内容：

container_commands:
    01_setup_apache:
        command: "aws s3 cp s3:elasticbeanstalk-us-west-2-273610000489/enable_mod_rewrite.conf /etc/httpd/co

我正在使用 AWS 弹性 beanstalk，由于我无法将 httdp conf 文件修改为 AllowOverride All 以便使用重写规则清理我的 URL，因此建议我使用 ebextensions： http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/customize-containers.html

更新：

我认为运行的问题是这样的：

RewriteEngine On

位于 htaccess 中。几乎就像它不能接受 rewritenegine 被打开一样。

在/var/log/httpd/access_log

在/var/log/eb-activity.log:

更新 3：

【问题讨论】：

你给的setup.config被切断了。

【参考方案1】：

在将 .ebextensions 提交到 Elastic Beanstalk 之前，请务必检查它们。我用来检查文件的资源http://www.yamllint.com/

如果您尝试修改 Apache 配置，那么我建议您在 ebextensions 中使用“文件”。 read more...

我相信您正在努力实现以下目标：

files:          
  "/etc/httpd/conf.d/enable_mod_rewrite.conf": 
     mode: "644"
     owner: root
     group: root
     content: |
       AllowOverride All

【讨论】：

感谢您的澄清和编辑。当使用 setup.config 中添加的建议命令上传新实例时，实例的运行状况变为红色，如我的初始帖子下的图像更新所示

检查您的错误日志 - 那里可能有用。

感谢您的建议。我在我的初始帖子下更新了更新 2。特别是在 /var/log/httpd/error_log 下什么都没有写

在您的 EBStalk 配置中；在网络层，负载平衡下，您的 EC2 实例运行状况检查是什么？如果你有一个把它拿出来再试一次。

嗨。 EC2 实例健康检查是什么意思？我用 ec2 health 中的值更新了我的初始帖子。它仍然是红色的，使用这个配置文件 + 在 htacess 中重写给出红色，没有这个配置文件它的绿色，但显然 htaccess 不起作用

【参考方案2】：

根据乔治的回答，这对我有用。可以帮助遇到同样故障的其他人：

files:
  "/etc/httpd/conf.d/enable_mod_rewrite.conf":
     mode: "644"
     owner: root
     group: root
     content: |
       <Directory /opt/python/current/app/>
       AllowOverride All
       </Directory>

这是使用 django 应用程序，因此您需要将 .htaccess 文件放在主项目目录中。如果您放置在静态文件夹中，则在登录弹出窗口上按取消后，只有未经授权的用户仍然可以看到/单击某些内容。
