亚马逊aws弹性豆茎。自定义配置文件不起作用

我在aws弹性beanstalk中遇到自定义配置文件的问题。

我的应用程序是python flask app。

我将01wsgi.config文件放入.ebextensions。

并将其压缩然后上传到弹性beanstalk。

源部署得很好,但配置没有执行。

如何使其正常工作?

目录结构:

source_root
  - .ebextensions
     -- 01wsgi.config
  - application
  - application.wsgi

01wsgi.config内容:

files:
  "/etc/httpd/conf.d/wsgi.conf":
    mode: "000644"
    owner: root
    group: root
    content: |
      LoadModule wsgi_module modules/mod_wsgi.so
      WSGIPythonHome /opt/python/run/baselinenv
      WSGISocketPrefix run/wsgi
      WSGIRestrictEmbedded On

我按照以下文件:

解决

将您的wsgi.conf文件放入.ebextensions目录。

制作一个将wsgi.conf复制到ondeck的配置文件。

01wsgi.config内容:

container_commands:
  replace_wsgi_config:
    command: "cp .ebextensions/wsgi.conf /opt/python/ondeck/wsgi.conf"

我想添加一些关于其他问题的信息:如果您进行不执行完整部署的更改(例如更改环境变量),Beanstalk将覆盖您的apache hosts文件。在大多数情况下,您的网络服务器将停止提供您的应用,除非您实际上没有自定义wsgi.conf

现在,要明确,您是正确的,因为您需要将您的WSGI配置放在.ebextentions目录中。然后使用container command将配置文件移动到EB查看的位置。您可以使用以下命令安全地执行此操作:

# Replace the default wsgi with ours
cp .ebextensions/wsgi.conf ../wsgi.conf

为防止在未执行部署的更新期间覆盖自定义wsgi.conf,您需要修补重新创建wsgi.conf的本机EB挂钩。我还没有找到任何关于此的文档,但是custom hooks已经记录在案,而本地文档也是以同样的方式工作。

这是我一直在使用的猴子补丁:

# Elastic Beanstalk always forces generation of apache hosts,
# stop it by returning true in the function that does it
sed '    /return True # DO NOT REGENERATE APACHE HOSTS/d' /opt/elasticbeanstalk/hooks/config.py \
  | sed -e 's/def generate_apache_config(params, filename):/def generate_apache_config(params, filename):\n    return True # DO NOT REGENERATE APACHE HOSTS/1' \
  -e 's/if not os.path.exists(WSGI_STAGING_CONFIG):/if not os.path.exists(WSGI_STAGING_CONFIG):\n        return True # DO NOT REGENERATE APACHE HOSTS/1' \
  > /tmp/config.py && mv -f /tmp/config.py /opt/elasticbeanstalk/hooks/config.py

SSH进入EB实例并查看/opt/elasticbeanstalk/hooks/config.py,您将看到EB在部署或更新环境期间所做的工作。

快乐的AWSing!
