Django应用程序无法在Elastic Beanstalk AWS上启动

时间：2018-04-04 13:35:47

标签： python django python-3.x amazon-web-services elastic-beanstalk

当我在弹性beanstalk上部署我的Django项目时，我收到500内部服务器错误。我已经尝试了所有的东西，EB仪表板看起来很好，健康是完美的，没有提到任何错误。任何人都可以对此有所了解吗？

在项目目录中，您应该有一个.elasticbeanstalk文件夹，您必须拥有另一个.ebextensions。如果您没有，请添加它。

然后，您必须创建文件以在EBT为您触发的实例上运行some stuff。例如，添加像10_packages.config这样的文件，这个数字很重要，因为它会保留订单。文件内容是这样的：

# 10_packages.config
# Add the packages needed to run the application and some other tools
packages:
    yum:
        git: []
        postgresql94-devel: []
        gcc: []
        gcc-c++: []
        make: []
        libffi-devel: []
        libmemcached-devel: []
        vim-enhanced: []

然后你需要安装django和你的应用程序所需的所有软件包。创建一个名为20_pip_requirements.config

的文件 
# 20_pip_requirements.config
# Update pip in the venv
commands:
  01_upgrade_pip_for_venv:
    command: "sudo /opt/python/run/venv/bin/pip install --upgrade pip"

最终，您必须迁移数据库，这必须只运行一次。让我们触发另一个文件30_migrate.config 

# 30_migrate.config
container_commands:
  01_migrate_database:
        command: "./manage.py migrate"
        leader_only: true

这只是一个例子，但是让你知道你必须做什么。
