- For the command-line interface method, type “sudo shutdown -r” or “reboot” in the terminal.
- If you have a graphical interface, open the terminal and use the same commands.
- Using SSH, connect to the remote server and enter the command “ssh -t [email protected] ‘sudo reboot'”.
- Save your work before rebooting and enter the password if required.
- Rebooting a Linux server may be necessary to resolve software issues, process updates, or implement configuration changes.
- Linux servers are known for their stability and may not require frequent reboots.
Rebooting a Linux Server Using the Command-Line Interface
One way to reboot a Linux server from Putty is by utilizing the command-line interface. This method is straightforward and requires using specific commands in the terminal. To initiate a reboot, you can type either “sudo shutdown -r” or simply “reboot” in the command-line interface.
When executing the command “sudo shutdown -r”, the server will go through a graceful shutdown process before restarting. This ensures that any running processes are properly terminated before the reboot. On the other hand, using the command “reboot” immediately initiates the restart without a graceful shutdown.
If you have a graphical interface available, you can also open the terminal and use the same aforementioned commands. In this case, the process remains the same, but you will have the visual advantage of using the graphical interface while executing the commands.
| Command | Description |
|---|---|
| sudo shutdown -r | Initiates a graceful shutdown followed by a restart of the Linux server |
| reboot | Immediately restarts the Linux server without a graceful shutdown |
Remember to save your work and close any open applications before executing the reboot command. It is also important to enter the password if prompted in order to authenticate the reboot request. By following these steps, you can efficiently and securely reboot your Linux server using Putty’s command-line interface.
Rebooting a Linux Server with a Graphical Interface
If you have a graphical interface on your Linux server, restarting it using Putty is just as simple. You can easily accomplish this by following a few straightforward steps in the terminal. First, open the terminal window by clicking on the appropriate icon or navigating to the applications menu. Once the terminal is open, you can proceed with the reboot process.
One method to restart your Linux server is by using the command: sudo shutdown -r. This command prompts the server to initiate a reboot. Alternatively, you can type the command reboot which achieves the same result. Both commands trigger the Linux server to go through the proper shutdown sequence and ultimately restart.
Before restarting your server, make sure to save any unsaved work and close any open applications. Entering the reboot command will prompt the system to request your password if required. Simply enter your password and the server will proceed with the reboot process. It is important to note that during the reboot, your server will temporarily be offline until it finishes starting up again.
Graphical Interface Reboot Command Example:
sudo shutdown -r
Rebooting a Linux server is often necessary to resolve software issues, apply updates, or implement configuration changes. Regular maintenance in the form of reboots can help keep your server running smoothly. However, it is worth noting that Linux servers are known for their stability and often do not require frequent reboots. Understanding how to reboot your server using Putty provides you with the flexibility to perform essential maintenance tasks whenever the need arises.
| Method | Command | Description |
|---|---|---|
| Graphical Interface | sudo shutdown -r | Restarts Linux server using the graphical interface. |
Rebooting a Linux Server Using SSH
Another option to reboot a Linux server remotely via Putty is by using SSH. SSH, or Secure Shell, allows you to securely connect to the remote server and execute commands. To reboot the server, simply open your Putty terminal and enter the following command:
Replace user with your username and server.com with the server’s domain or IP address. The
1 | -t |
flag ensures that a terminal is allocated for the command execution. If prompted, enter your password for authentication.
It is important to save your work before rebooting the server as any unsaved changes may be lost. Additionally, ensure that you have the necessary permissions to execute the reboot command. The server may prompt you for administrative privileges, in which case you should enter your password again.
Rebooting Linux Server Using SSH Example
Here’s an example of rebooting a Linux server remotely through Putty using SSH:
| Step | Action | ||
|---|---|---|---|
| 1 | Open Putty and enter the server’s IP address or domain in the “Host Name” field. | ||
| 2 | Choose the SSH protocol and Port 22. | ||
| 3 | Click “Open” to establish the SSH connection. | ||
| 4 | Enter your username and password when prompted. | ||
| 5 | Type the command
and press Enter to initiate the server reboot. |
||
| 6 | Confirm the reboot by entering your password again if required. |
Remember, Linux servers are known for their stability and may not require frequent reboots. However, if you encounter software issues, need to process updates, or make configuration changes, rebooting the server can help resolve these matters effectively.
Reasons for Rebooting a Linux Server
There are several reasons why rebooting a Linux server becomes necessary. One of the most common reasons is to resolve software issues. Over time, a server may encounter bugs or glitches that can impact its performance. By rebooting the server, you can clear out any temporary files or processes that may be causing the issues and start fresh. It’s like giving your server a clean slate to work from, allowing it to run smoothly and efficiently.
Another reason for rebooting a Linux server is to apply updates. Linux servers frequently receive updates to improve security, add new features, or fix any known vulnerabilities. These updates often require the server to be restarted in order for the changes to take effect. By rebooting the server, you ensure that all updates are properly installed, reducing the risk of any potential issues or security breaches.

Furthermore, rebooting a Linux server may be necessary when implementing configuration changes. Whether you’re making changes to network settings, installing new software, or updating system configurations, a reboot is often required to apply these changes accurately. It allows the server to reconfigure itself with the new settings, ensuring that everything is in place and functioning as intended.
It’s worth noting that Linux is known for its stability and may not require frequent reboots compared to other operating systems. However, occasional reboots are still necessary to maintain the server’s performance and ensure that any updates or changes are fully implemented. By understanding the reasons for rebooting a Linux server, you can confidently manage and maintain your server’s functionality.
