【问题描述】：
我正在尝试部署一个我一直在使用 django 进行的项目。在开发中，我一直在使用 SQLite，在生产中我正在尝试使用 MySQL。
通常当我创建 EB 实例时，一切运行正常，并且控制台显示状态正常。在尝试部署（在 ebcli 中运行 eb deploy）时，我遇到了以下错误
2020/06/18 15:59:50.357281 [INFO] Copying file /opt/elasticbeanstalk/config/private/rsyslog.conf to /etc/rsyslog.d/web.conf

罪魁祸首似乎是我的db迁移命令，如下，在'.ebextensions'中，命名为'db-migrate.config'
container_commands:
01_migrate:
command: "django-admin.py migrate"
leader_only: true
option_settings:
aws:elasticbeanstalk:application:environment:
DJANGO_SETTINGS_MODULE: djangomicroblog.settings
原来的错误信息也指向我来自'/var/log/cfn-init.log的日志，这里看到的错误如下
2020-06-18 14:18:23,279 [ERROR] -----------------------BUILD FAILED!------------------------
2020-06-18 14:18:23,279 [ERROR] Unhandled exception during build: Command 01_migrate failed

File "/usr/lib/python2.7/site-packages/cfnbootstrap/command_tool.py", line 117, in apply
raise ToolError(u"Command %s failed" % name)
ToolError: Command 01_migrate failed
我已尝试搜索这些错误消息，但结果非常有限且似乎不起作用。
我的settings.py中设置数据库的函数也如下
def get_db():
try:
return {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': os.environ['RDS_DB_NAME'],
'USER': os.environ['RDS_USERNAME'],
'PASSWORD': os.environ['RDS_PASSWORD'],
'HOST': os.environ['RDS_HOSTNAME'],
'PORT': os.environ['RDS_PORT'],
}
}
except:
return {
'default': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
}
}
DATABASES = get_db()
任何帮助将不胜感激

你解决了吗？我有同样的问题。
-
我做到了，原来问题是我为 Amazon linux 1 环境设置了应用程序，但我使用的是 amazon linux 2 环境。 Amazon linux 2 似乎很新，我找不到转换我的应用程序的方法，所以我在 amazon linux 1 中重新制作了环境（python 3.6 而不是 3.7）。我的另一篇文章有更多细节

解决方法跟我一样！感谢您的回答，祝您有愉快的一天。
