How to create and connect to your first C1 server

How to create and connect to your first C1 server

This page shows how to create and connect to your first C1 server.

Requirements

  • You have an account and are logged into cloud.scaleway.com
  • You have configured your SSH Key

Each server that you create is a physical server dedicated for you, there is no virtualization.

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.

You can select the type of disk to host your volumes from two technologies:

  • LSSD (Local solid state drive) to deliver fast disk I/O.
  • LHDD (Local spinning disk), use for moderate read/write access.

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 fstab (automatic mount)

To mount additional volumes automatically, you have to reference your devices in the /etc/fstab file.
/etc/fstab references all devices to mount when they are connected.

For instance to mount /dev/nbd1 device automatically to the /mnt/data directory, the /etc/fstab has the following content:

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>

/dev/nbd1 /mnt/data auto  defaults,nobootwait,errors=remount-ro 0 2

The configuration above mounts the /dev/nbd1 device to the /mnt/data directory with fstab default option and nobootwait.
nobootwait is set to prevent boot problems in the case your volume is not yet downloaded to the local storage.

Create the /mnt/data directory if it doesn’t exist.

root@c1-X-Y-Z-T:~# mkdir -p /mnt/data

To check devices are mounted properly, run the mount -a command to mount all devices.

Important: On the next server boot, your volumes will be mount automatically.

Now run the df -h command, this command will list all your devices and where they are mounted:

root@c1-X-Y-Z-T:~# df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/nbd0        23G  420M   22G   2% /
none           1010M   36K 1010M   1% /dev
none            203M   80K  203M   1% /run
none            5.0M     0  5.0M   0% /run/lock
none           1012M     0 1012M   0% /run/shm
none            100M     0  100M   0% /run/user
/dev/nbd1       9.2G  149M  8.6G   2% /mnt/data
