## Assumptions

* Access to your web host with SSH
* A functional static website built with Hugo

The spoiler is that you can deploy your entire website with a command that looks like the following:

```bash
hugo && rsync -avz --delete public/ www-data@ftp.topologix.fr:~/www/
```

As you will see, we put it in a shell script file, which makes building and deployment as easy as executing `./deploy`.

## Install SSH Key

If it is not done yet, we will make an automated way to SSH to your server. If you have already installed an SSH key, switch to the next section.

First, install the ssh client. On Debian/Ubuntu/derivates, use the following command:

{{% code file="install-openssh.sh" %}}
```bash
sudo apt-get install openssh-client
```
{{% /code %}}

Then generate your ssh key by entering the following commands:

```bash
~$ cd && mkdir .ssh & cd .ssh
~/.ssh/$ ssh-keygen -t rsa -q -C "For SSH" -f rsa_id
~/.ssh/$ cat >> config <<EOF
Host HOST
     Hostname HOST
     Port 22
     User USER
     IdentityFile ~/.ssh/rsa_id
EOF
```

Don't forget to replace the `HOST` and `USER` values with your own ones. Then copy your ssh public key to the remote server:

```bash
~/.ssh/$ ssh-copy-id -i rsa_id.pub USER@HOST.com
```

Now you can easily connect to the remote server:

```
~$ ssh user@host
Enter passphrase for key '/home/mylogin/.ssh/rsa_id':
```

And you've done it!

## Shell Script

We will put the first command in a script at the root of your Hugo tree:

```bash
~/websites/topologix.fr$ editor deploy
```

Here you put the following content. Replace the `USER`, `HOST`, and `DIR` values with your own:

```bash
#!/bin/sh
USER=my-user
HOST=my-server.com
DIR=my/directory/to/topologix.fr/   # might sometimes be empty!

hugo && rsync -avz --delete public/ ${USER}@${HOST}:~/${DIR}

exit 0
```

Note that `DIR` is the relative path from the remote user's home. If you have to specify a full path (for instance `/var/www/mysite/`) you must change `~/${DIR}` to `${DIR}` inside the command line. For most cases you should not have to.

Save and close, and make the `deploy` file executable:

```
~/websites/topologix.fr$ chmod +x deploy
```

Now you only have to enter the following command to deploy and update your website:

```
~/websites/topologix.fr$ ./deploy
