I have a MongoDB instance on my EC2 server that I want to be accessible both from the machine itself (on localhost) and also remotely.
I currently have it configured so that I can connect to my db from the machine itself on localhost:27017 (with read/write access). I want to make this db available (but only readonly) to other clients via my.ip.address:27017.
How would I go about setting this up?
If you turn on authentication as well as adding an local user with both read and write permissions you can also add a read-only user.
You would have to manage the authentication in your application / shell code but basically, anyone not from local host should authenticate as the read only user.

I am brand new to RDS and have only used postgres through Rails and/or Heroku for the most part, so not that deep into database management. All I am trying to do is verify I can connect to the RDS instance I just created on AWS, but it is hanging, psql reporting this after hanging for about 30 seconds or a few minutes I guess:
$ psql postgresql://myuser:mypass#myawshost.rds.amazonaws.com:5432/my-db-name
psql: error: could not connect to server: Operation timed out
Is the server running on host "myawshost.rds.amazonaws.com" (<the ip address>) and accepting
TCP/IP connections on port 5432?
How do I connect to my AWS RDS instance from localhost?
I am sure I have the correct username and password.
I am sure the host is correct.
I am not sure if I should be including the port.
I am not sure if I am supposed to put a DB name, as under the "Configuration" tab in the RDS admin console for my database, it says DB instance ID: my-db-name, Engine version: 13.3, DB name: -, I am not sure if that - is my actual postgres db name or my-db-name is....
I tried this with the db name and it still hangs:
$ psql postgresql://myuser:mypass#myawshost.rds.amazonaws.com:5432/-
I edited the security group which is linked under the VPC security groups section of the Connectivity & security tab of https://console.aws.amazon.com/rds/home, so it allows all incoming connections. I also tried limiting to just my IP address as incoming connections.
Any help would be appreciated, thanks. Not sure why it would just be hanging. I have used a local version of postgres just fine, but connecting to postgres RDS is not working.
Underneath the Connectivity and Security > Security section I just noticed it says Public accessibility: No. Must I enable something else? There is also one VPC, one Subnet group, and several Subnets, which I don't know too much about, must I do something there?
Finally, "status" says Available with a green light, so things seem fine there.
I found a useful link in AWS knowledge center, I hope this will help you.
Btw if your RDS is deployed in a public subnet, yes you need to enable if you want to access RDS over the internet.
My DB instance is in a public subnet, and I can't connect to it over the internet from my local computer
This issue can occur when the Publicly Accessible property of the DB instance is set to No. To check whether a DB instance is publicly accessible, you can use the Amazon RDS Console or the AWS CLI.
To change the Publicly Accessible property of the Amazon RDS instance to Yes:
Verify that your VPC has an internet gateway attached to it. Make sure that the inbound rules for the security group allow connections.
Open the Amazon RDS console.
Choose Databases from the navigation pane, and then select the DB instance.
Choose Modify.
Under Connectivity, extend the Additional configuration section, and then choose Publicly accessible.
Choose Continue.
Choose Modify DB Instance.
Note: You don't need to choose Apply Immediately. For more information about how Apply Immediately can affect downtime, see Using the Apply Immediately parameter.

I used mongodb on my local without authentication by running mongod as server and connecting it by just mongo as a user.
Now after creating users and running the server as mongod --auth i can connect using user id and pwd assigned by me.
The problem is while connecting back mongo with mongod it again gets connected to the database and whole database is visible again,this should not happen as I have enabled the authentication.
Using mongod as a server should block the users from getting access. Same is the problem for my personal server.
Is there any solution to enable the security permanently that is enable mongod --auth and not just mongod.
If I understand correctly, your concern is that restarting a mongod process without access control enabled allows you to access data without authentication. This is the expected outcome: a user with direct access to restart services or copy MongoDB data files has greater permissions than the mongod process.
Authentication only verifies remote client access to the mongod service: it does not encrypt or protect data files if a user has direct local read access. If you have an environment allowing remote and/or multi-user access, you should take steps to appropropriately limit access to your data files and service management.
If you want to secure data files from direct access, it sounds like you may be looking for Encryption at Rest or Disk Encryption. These security measures prevent direct read access to your data files or filesystem without appropriate credentials, but you still have to limit access appropriately and protect those credentials.
For general measures see the MongoDB Security Checklist.
I have enabled the security.authorization setting in /etc/mongod.conf
security:
authorization: enabled
But I am still able to connect to the mongo shell without providing credentials.
mongo
Enabling security.authorization seems to enforce access control on the databases and the anonymous user doesn't seem to be able to perform any actions such as listing databases and/or collections.
I have attempted to enable auth in the /etc/mongodb.conf file, but this didn't seem to have any effect and I can still connect anonymously.
auth = true
How do I set the mongo shell to require authentication so that anonymous connections are blocked.
The authorization mode in mongodb does not work like mysql.
It will prevent non authorized or anonymous users to read or write the DB but it won't forbid people to connect to your DB.
Anonymous users will always be able to connect themselves but can't do anything.
If you want to block the connection from unknown users or server, you can enable the net.bindIp parameter to allow only the selected IP to connect to your database.
I can't seem to connect to Cloud SQL with Workbench. I keep getting this error.
Failed to Connect to MySQL at CLOUD-SQL-IPv4:3306 with user root
Access denied for use 'root'#'WHITE-LISTED-IP-ADDRESS' (using password: YES)
I have white listed my IP.
I have set an IP for the SQL instance.
I have checked the username and Password several times.
Any idea why this is happening?
It seems you have to create a new user in the Google Cloud Console with the host name set to %(any host). You can't seem to connect using the root user.
Is it possible to connect with the #root user but after you finish the setup you have to restart the sql server.
What is important to set up an SSL certificate if you connect to you production database, but if you only try it out you can allow unsecured connection. Another important thing is to add your IP to the Authorised Networks in the Connection tab.
I have a mongodb running in my server, for local connections to the db I don't need any password to protect it(that is within the same physical machine, meaning connect to the server thru the 127.0.0.1 ip address).
But I don't want other people in the network be able connect to my database without password, only the authorized user. So I want to do password protection for the remote user.
How to do it?
Right now monogdb does not support authentication mode based on the user location. So that means if you run mongod with --auth that will apply to everyone.
There are no (yet) advanced authentication schemas like IP, protocol source, etc. For now you can only define if the user has read only or write permissions on a database. So basically the only thing mongodb cares is if you typed the right password for the right user.
Personally in all production environment I would recommend to use the secure mode, because even if you allow only connection from a localhost any users who has access to the local server or any malicious script on the host can easily wipe all your data.
The MongoDB Security and Authentication page has information on configuring user authentication and firewall settings.
Note that when you enable password authentication for a database, the authentication requirement will apply to both local and remote users (so you will also need to connect with a password through the local IP).
MongoDb does not offer an easy way to protect the database. I assume this is the reason why there are tens of thousands of mongodb instances on the net that are unprotected for hackers
