How to create and connect to your first server

How to create and connect to your first instance

This page shows how to create and connect to your first Scaleway instance.

Requirements

After you’ve launched your server, you can connect to it as root and use it as you wish.

There are five steps to provision a new server

  • Name & tag your server
  • Choose your image
  • Add storage
  • Start the server
  • Mount additional volumes (Optional)

Important: Your SSH public keys are fetched during the boot process.

If you add them after your server is booted, they will not be added to your authorized_keys file.

If you do not want the keys to be downloaded during the next boot, execute the following command on your server:

root@c1-X-Y-Z-T:~# echo manual > /etc/init/ssh-keys.override

Server creation

Before starting, click the “Create Server” button in the control panel.

Control Panel

Step 1 - Name & tag your server

You will land on the server-creation page where you must input basic information for your server:

  • The name of your server
  • The tag you want to assign to it (Optional). Tags let you organize your servers, you can assign any tag to each server.

Create server basic information

Step 2 - Choose your image

After inputting your server basic information, you have to choose a starting image for your server.

You can choose this image from three sources:

Create server image

Step 3 - Add storage

A simple solution to increase the storage for your servers is to add extra volumes.

You can add extra storage to your server. Added storage can be an existing volume or new volume.

Create server volumes

Step 4 - Start your server

Click the “Create Server” button. This action starts your server. In a few seconds, your server will be ready to use.

Log into your server

When your server is running, you can see the server’s IP address in the server list on the control panel.

For OSX and Linux

On a Mac or Linux computer, open your terminal program and in the shell just type the following command:

john@localhost:~$ ssh -i ~/.ssh/your_private_key root@your_server_ip

Allow the connection to the host:

The authenticity of host 'myhost.ext (212.47.226.35)' can't be established.
RSA key fingerprint is 4f:ba:65:cf:14:64:a7:1e:b6:07:7c:00:71:95:21:fa.
Are you sure you want to continue connecting (yes/no)?

Well done, you are now logged into your server!

For Windows

On Windows, you will need a small application named PuTTy, an SSH client. You can download putty here.

Once you have downloaded PuTTY, just start the program.

  • Fill the “Hostname” field with your server’s IP address
  • In the left-side menu, under Connection, expand the SSH sub-category
  • Select the Auth sub-category and click the “Browse” button
  • Select the private key file you generated previously
  • Return in the Session category and click the “Open” button

Import your SSH key on Putty

You are now logged into your server from Windows!

Mount additional volumes

Format additional volumes

If the new volume has never been formatted, you need to format the volume using mkfs before you can mount it.

For instance, the following command creates an ext4 file system on the volume:

root@c1-X-Y-Z-T:~# mkfs -t ext4 /dev/nbd1
mke2fs 1.42.9 (4-Feb-2014)
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
Stride=0 blocks, Stripe width=0 blocks
610800 inodes, 2441406 blocks
122070 blocks (5.00%) reserved for the super user
First data block=0
Maximum filesystem blocks=2503999488
75 block groups
32768 blocks per group, 32768 fragments per group
8144 inodes per group
Superblock backups stored on blocks:
  32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632

Allocating group tables: done
Writing inode tables: done
Creating journal (32768 blocks): done
Writing superblocks and filesystem accounting information: done

Mount additional volumes manually

To mount the device manually as /mnt/data, run the following commands:

root@c1-X-Y-Z-T:~# mkdir -p /mnt/data
root@c1-X-Y-Z-T:~# mount /dev/nbd1 /mnt/data
root@c1-X-Y-Z-T:~# ls -la /mnt/data/
total 24
drwxr-xr-x 3 root root  4096 Jan  1 00:07 .
drwxr-xr-x 3 root root  4096 Jan  1 00:07 ..
drwx------ 2 root root 16384 Jan  1 00:07 lost+found

Mount additional volumes with systemd (automatic mount)

To mount the additional volume automatically, you can create a systemd script that will mount your volumes automatically during the boot of your cloud server.

If not yet done, create the directory into you want to mount your volume: mkdir -p /mnt/data

As the volume is empty by default, you have to create a filesystem before you can use it. To format it with with an ext4 filesystem, use the following command: mkfs -t ext4 /dev/nbd1

To get the UUID of your volume, run the command blkid and take a note of the ID as you will need it in the next step.

Create or edit the file that corresponds to the path of your directory nano /etc/systemd/system/mnt-data.mount and edit is as following: The file name of the script must correspond to the path where you mount the volume (/mnt/datamnt-data.mount)

[Unit]
Description=Mount NDB Volume at boot

[Mount]
What=UUID="16575a81-bb2c-46f3-9ad8-3bbe20157f7c"
Where=/mnt/data
Type=ext4
Options=defaults

[Install]
WantedBy=multi-user.target

Replace UUID with the ID of your volume.

Now reload systemd: systemctl daemon-reload Launch the script to mount the volume: systemctl start mnt-data.mount Finally enable the script to mount your volume automatically during boot: systemctl enable mnt-data.mount

Your volume will automatically be mounted after a reboot. You can run the df -h command, this command will list all your devices and where they are mounted:

root@scw-65acb0:~# df -h
Filesystem      Size  Used Avail Use% Mounted on
udev           1009M     0 1009M   0% /dev
tmpfs           203M   12M  191M   6% /run

tmpfs          1011M     0 1011M   0% /dev/shm
tmpfs           5.0M     0  5.0M   0% /run/lock
