Question

我有一个与ElasticBeanstalk关联的EC2实例，在该实例上部署了我的flask应用程序。我已经使用flask，python实现了一些其他的API。

我在Linux 2上创建了另一个EC2实例，该实例上安装了MongoDB社区版。我注意到它在/etc/mongod.conf文件中映射了一个本地IP：

# network interfaces
net:
  port: 27017
  bindIp: 127.0.0.1

根据我的理解，我需要将EC2实例的私有IP（烧瓶应用程序）映射到它：

# network interfaces
net:
  port: 27017
  bindIp: <private ip of EC2 with flask app>

这样我就可以从flask应用访问该实例上安装的MongoDB。

# configuring mongo
application.config["MONGO_DBNAME"] = "my_db"
application.config["MONGO_URI"] = "mongodb://public_ip_of_mongodb:27017/my_app"

由于某些原因，一旦我编辑'/etc/mongod.conf文件'mongod服务就会开始失败：

即使我将bindId还原为127.0.0.1，它仍然会失败。

我在这里错过了什么吗？

更新bindIp mongod服务失败后，AWS EC2 Linux实例
