Installing or reinstalling your dedicated server
You can easily reinstall your server and choose a different OS image in your OVHcloud Control Panel.
- Click
Bare Metal Cloud
from the top navigation bar. - Select
Dedicated servers
and then select your server's name. - In the General information panel, next to Operating system (OS) click the more options
...
button and selectInstall
.
In the popup window, select one of the installation options:
-
Install from an OVHcloud template: You can select the OS and customize the server configuration.
NOTE: You can install from a custom image by selecting Custom on the following screen. Please see our BYOI/BYOLinux Comparison guide for more information.
-
Install one of your templates: To apply a customized template, you need to have saved at least one server configuration. To do this, check the option
Save this installation
in Step 4 of the installation process.
You can manage all your licenses in the
Bare Metal Cloud
section under Licenses
. In this section, you can also order licenses or add existing ones via the Actions
button.
Select Install from an OVHcloud template
, then click Next
.
Select the operating system from the drop-down menus.
If you need to modify the partitioning scheme of your operating system, check the Customise the partition configuration box before clicking on Next
.
In this step, you can set up RAID and partitioning options within the limits of the server's hardware and operating system.
If you don't want to use all your disks for the installation, you can update it after checking the Customise the partition configuration box. In this case, you will be responsible for mounting the other disks in the operating system. You should refer to the operating system documentation to find out how to do this.
After you have finished your adjustments, click Next
.
On the summary page, you will find additional questions that are specific to the chosen operating system.
For example, if you are installing a GNU/Linux-based operating system, you can add your SSH key in the last step of the installation process.
For a detailed explanation of how to generate SSH keys, please refer to this guide.
Finally, click Confirm
to trigger the operating system installation on your dedicated server.
Logging on to your server
This tutorial is designed to help you as much as possible with common tasks. If you are having difficulty performing these actions, please contact a specialized service provider. OVHcloud can't provide you with technical support in this regard.
If you have installed an OVHcloud OS template on your server, a user with elevated permissions is created automatically. This user will be named according to the operating system, e.g. "ubuntu" or "rocky".
You will then receive an email containing the information needed to establish a first connection with SSH. SSH is a secure communication protocol, used to establish encrypted connections to a remote host. You can find more detailed information in our guide: Getting started with SSH.
Most current desktop operating systems will have an Open SSH client natively installed. This means that your access credentials allow you to quickly establish a connection to your server in the appropriate command line application (Terminal
, Command prompt
, Powershell
, etc.). Enter the following command:
Example:
You can use any third-party application compatible with Open SSH as well.
Once connected, you can replace the predefined password for the current user with a better passphrase by using this command:
On a GNU/Linux distribution, a password prompt will not display your keyboard inputs.
Type your current password and press Enter
. Enter the new passphrase and type it again at the next prompt to confirm it.
Activating the root user account
It is not necessary to use the "root" user account to get started with administrating your server. This account has to be enabled first in the server OS in order to use it. Moreover, SSH connections with the user "root" are disabled by default as a security measure.
Unless stated otherwise, all administrative actions described in our documentation can be accomplished by the default user account, i.e. typing sudo
followed by the respective command.
Depending on your requirements for security, mobility and convenience, SSH keys can serve as an additional connection method or replace logins with username and password. Find out how to use them in our guide: Creating and using SSH keys.
Once the installation is completed, you will receive an email with your Windows login credentials. You can then connect to your server via RDP (Remote Desktop Protocol). On your local Windows device, open the Remote Desktop Connection
client application.
Enter the IPv4 address of your server, then your username and passphrase. Usually a warning message will appear, asking to confirm the connection because of an unknown certificate. Click on Yes
to log in.
You can use also use any third-party application compatible with RDP. This is a requirement if your local device does not have Windows installed.
As a fallback option, you can use the IPMI console in your OVHcloud Control Panel to connect.
▼ Enabling Windows boot logs (optional)
Windows boot logs can be helpful for server error diagnostics.
To activate them, follow the steps below:
- Connect to your server via RDP or IPMI.
- Open the Windows start menu and click on
Run
.
- Enter "msconfig" and click on
OK
.
- In the new window, activate the logs option next to
Boot log
. Click onOK
.
The next time your server boots, logs will be saved into a .txt
file. The file path is: C:\Windows\ntbtlog.txt
.
To access the log file in rescue mode, please follow the instructions in the rescue mode guide.
Restarting your dedicated server
A reboot might become necessary to apply updated configurations or to fix an issue. Whenever feasible, perform a "soft reboot" via the command line:
However, you can carry out a "hard reboot" at any time in your OVHcloud Control Panel. From the General information
tab, click on ...
next to "Status" in the Service status box, then click Restart
and Confirm
the action in the popup window.
Securing your dedicated server
As explained in the “Objective” section of this guide, you are the administrator of your dedicated server. As such, you are responsible for your data and its security. You can learn more about securing your server in this guide.
If your server runs Windows, use this guide.
OVHcloud Monitoring
You can set the monitoring status for a dedicated server from the General information
tab in your OVHcloud Control Panel (section Service status) by clicking the Configure
button.
In the popup window, you have three options for monitoring behavior:
- Disabled: This option stops alert messages and interventions by OVHcloud. Choose this if you are executing pertinent administrative actions on the server that prevent an ICMP response.
- Enabled with proactive intervention: If the server stops responding, an alert email is sent to you and the server will be checked by a technician.
- Enabled without proactive intervention: You will receive an alert message by email in case the server stops responding. To initiate an intervention, you will need to create a support request.
Click on Confirm
to update your monitoring configuration.
You can find more information about OVHcloud Monitoring in this guide.
Network configuration
Network bridging
Network bridging is the action taken by network equipment to create an aggregate network from either two or more communication networks, or two or more network segments. Bridging is distinct from routing, which allows the networks to communicate independently while remaining separate.
The Network Bridge configuration is most commonly used in the context of virtualization, to allow each Virtual Machine to have its own public IP address.
For more information on network bridging, see our Configuring a Network Bridge guide.
IP aliasing
IP aliasing is the process of associating two or more IP addresses to the same network interface. This allows your server to establish multiple connections to a network, each serving a different purpose.
For detailed instructions on how to configure IP aliasing, please refer to this guide.
IPv6 configuration
All OVHcloud dedicated servers are delivered with a /64 IPv6 block. To use the addresses in this block, you will need to make some network configuration changes. Please refer to our guide: IPv6 Configuration.
Rescue mode
For any kind of issue, the first general troubleshooting step to take is rebooting your server into rescue mode from your OVHcloud Control Panel. It is important to identify server issues in this mode to exclude software-related problems before contacting our support teams.
Please refer to the rescue mode guide.
Access using IPMI
OVHcloud deploys all dedicated servers with an IPMI (Intelligent Platform Management Interface) console which runs in your browser or from a Java applet and enables you to connect directly to your server even if it has no network connection. This makes it a useful tool for troubleshooting issues that may have taken your server offline.
For more information, please refer to our guide: Using the IPMI with dedicated servers.
Backup and recovery
Our Getting Started - Backing Up a Bare Metal Server with Veeam Enterprise guide can guide you through the process of using S3 Object Storage as a backup and recovery solution.
