How to connect to a MongoDB server with SSH tunnel using a Private key
April, 19, 2024
To generate SSH keys in macOS, follow these steps:
- 1. Open up the Terminal by going to Applications -> Utilities -> Terminal
- 2. Enter the following command in the Terminal window:
ssh-keygen -t rsa-
3. Next, you will be prompted to provide the location where you want to create the private key file:
Enter file in which to save the key (/Users/youruser/.ssh/id_rsa):You can leave this empty to create the key in the default location, which is /home/youruser/.ssh/id_rsa, but we recommend to change it to the /Users/youruser/.ssh/mongolime for instance. The public key file will be created in the very same location, and with the same name, but with the .pub extension.
- 4. Afterwards, you will be prompted to choose a password. This is the password required to use the private key.
Enter passphrase (empty for no passphrase):
That completes the key generation. Below is an example of the entire process:
$ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/bushev/.ssh/id_rsa): /Users/bushev/.ssh/mongolime
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /Users/bushev/.ssh/mongolime.
Your public key has been saved in /Users/bushev/.ssh/mongolime.pub.
The key fingerprint is:
SHA256:Z8Jub9g8YsWPRADJ5k7v7YzW24deY2f53kGjrMEaHM4 [email protected]
The key's randomart image is:
+---[RSA 2048]----+

| oSo=o. o o|
| .++E.o.o .o|

- 5. Copy public key to a server
ssh-copy-id -i ~/.ssh/mongolime.pub user@host
This logs into the server host, and copies keys to the server, and configures them to grant access by adding them to the authorized_keys file. The copying may ask for a password or other authentication for the server. Only the public key is copied to the server. The private key should never be copied to another machine.
- 6. Finally, copy-paste content of a Private key file to a the MongoLime connection settings.
