How to connect to the server via SSH after deployment?
|
||||
</summary>
|
||||
|
||||
After deployment, the default username for an Ubuntu instance is **ubuntu**, and for a Debian instance it is **admin**. Amazon EC2 does not allow users to access newly created instances with an SSH password. Instead, users are required to create "key pairs", which are used as credentials for SSH access.
|
||||
You need to know the username and the private key for your instance in order to login to it via SSH.
|
||||
|
||||
This template generates a key pair for you during deployment, and the private key will be available as text under the **Outputs** tab after the stack is successfully created.
|
||||
Each Linux server distribution on AWS has its own default login username, while password login is disabled since the use of private key, or "key pairs", is enforced.
|
||||
|
||||
The following is a list of default usernames used by the distributions provided:
|
||||
> **Reference**: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/connection-prereqs.html
|
||||
|
||||
| Distribution | Default Login Username |
|
||||
| --- | --- |
|
||||
| Ubuntu (`Ubuntu *.04`) | `ubuntu` |
|
||||
| Debian (`Debian 9` only) | `admin` |
|
||||
| CentOS (`CenOS 7` and `CentOS 8`) | `centos` |
|
||||
| AmazonLinux2 | `ec2-user` |
|
||||
|
||||
For the private key(aka "Key pair"), this template generates one for you during deployment, and it will be available as text under the **Outputs** tab after the stack is successfully created.
|
||||
|
||||
You will need to save the private key from the **Outputs** tab to a file on your computer, if you want to access the VPN server via SSH.
|
||||
|
||||
> **Note:** You may need to format the private key by replacing all spaces with newlines, before saving to a file.
|
||||
> **Note:** You may need to format the private key by replacing all spaces with newlines, before saving to a file. The file also needs to be set with [proper permission](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/connection-prereqs.html#connection-prereqs-private-key) before it can be used by SSH client.
|
||||
|
||||
|
||||
|
||||
To add proper permissions to your private key file, run the following command under the directory where the file is located:
|
||||
```bash
|
||||
sudo chmod 400 my-key-pair.pem
|
||||
```
|
||||
|
||||
As a result, the command to login to your instance should look like:
|
||||
```bash
|
||||
$ ssh -i path/to/your/key.pem instance-username@instance-ip-address
|
||||
```
