node.js - Connect to MongoDB hosted on AWS ec2 from Elastic Beanstalk -

-

i'm trying host web app on aws.

i'm hosting nodejs app on elastic beanstalk (salable). have created ec2 instance host mongodb.

in test, mongodb ec2 instance accepts connection @ port 27017 anywhere. , website works great.

the problems want restrict access mongodb ec2 instance allow connections elastic beanstalk app.

i changed rule of ec2 instance security group, accept tcp port 27017 connection security group elastic beanstalk app assigned to.

this breaks communication mongodb app immediately.

i have tried allow traffic beanstalk security group, no luck

have got wrong? please help!

needed edit /etc/mongod.conf file , set bind_ip = 0.0.0.0 in order make connections externally.

also had try different version of mask work. xxx.xxx.0.0/16 worked me, xxx.xxx.0.0/24 , xxx.xxx.0.0/32 didn't.

also, recommended use private ip if in same zone (keeps costs down), public otherwise.
