You need to be careful with permissions:

Create ~/.ssh:
```
$ mkdir ~/.ssh
```
Create ~/.ssh/authorized_keys:
```
$ touch ~/.ssh/authorized_keys
```
Make sure you have the right permissions:
- Home directory on the server should not be writable by others:
```
$ chmod go-w ~
```
- SSH folder on the server needs 700 permissions:
```
chmod 700 ~/.ssh
```
- Authorized_keys file needs 644 permissions:
```
chmod 644 ~/.ssh/authorized_keys
```
Add your key to ~/.ssh/authorized_keys. You can either add it manually or use
```
$ ssh-copy-id user@host
```
