Open a terminal window by pressing Ctrl+Alt+T on your keyboard.
2. Edit the `/etc/environment` file using your favorite text editor (e.g., nano or vim). For example:
# This script opens the /etc/environment file using the nano text editor with root privileges.
# The "sudo" command allows the user to execute a command with root privileges.
# The "nano" command opens the nano text editor.
# The "/etc/environment" argument specifies the file to be opened.
sudo nano /etc/environment
# This script edits the /etc/environment file using the nano text editor with root privileges.
# The "sudo" command allows the user to execute a command with root privileges.
# The "nano" command opens the nano text editor.
# The "/etc/environment" argument specifies the file to be edited.
sudo nano /etc/environment
3. Add the following line to the end of the file, replacing “http://proxy-server:80” with the actual address and port number of your proxy server:
# Set the variable http_proxy to the address and port number of the proxy server
# Note: This allows the script to use the proxy server for internet connections
http_proxy=http://proxy-server:80 # Replace "proxy-server" with the actual address of the proxy server and "80" with the port number
# Note: The "http_proxy" variable is used by many programs to determine the proxy server to use for internet connections. The format is "http://address:port".
4. Save and close the `/etc/environment` file.
5. Restart the network service to apply the changes:
# This script restarts the network service to apply changes made in the /etc/environment file.
# Use sudo to run the command as root user.
sudo systemctl restart networking
# The systemctl command is used to manage system services, in this case, the networking service.
# The restart option restarts the service, applying any changes made to its configuration.
# This command can also be written as:
# sudo service networking restart
# However, the systemctl command is preferred as it is more modern and provides more features.
# It is important to restart the network service after making changes to the /etc/environment file.
# This file contains system-wide environment variables, which are used by all users and processes.
# Restarting the network service ensures that the changes made in the file are applied and available to all users and processes.
6. Verify that the proxy server is working by running a simple command, such as “curl http://google.com”. If you see output from Google’s website, then everything is set up correctly.
To configure specific applications to use the proxy server (e.g., Firefox or wget), consult their documentation for instructions.
But wait! What if you don’t want to mess with your `/etc/environment` file? Maybe you prefer a more user-friendly approach, like using a GUI tool. Well, Ubuntu Server has got you covered there too!
1. Install the “Proxy Configuration” package:
# This script installs the "Proxy Configuration" package on Ubuntu Server.
# First, we use the `sudo` command to run the following command as root user.
sudo apt install proxyconfig
# The `apt` command is used to manage packages on Ubuntu. Here, we are using it to install the "Proxy Configuration" package.
# The `install` option is used to install a new package.
# The `proxyconfig` package is the one we want to install.
# After running this command, the user will be prompted to enter their password to confirm the installation.
# Once the installation is complete, the "Proxy Configuration" package will be available for use.
# If you don't want to modify your `/etc/environment` file, you can use a GUI tool instead.
# Ubuntu Server provides a user-friendly approach for configuring proxies.
# To use this tool, we first need to install it. We can do this by running the following command:
sudo apt install proxyconfig
# This will install the "Proxy Configuration" package, which includes the GUI tool.
# Once the installation is complete, the tool will be available for use.
# This script is now ready to be used for installing the "Proxy Configuration" package on Ubuntu Server.
2. Open the Proxy Configuration window by running this command in your terminal:
# This script opens the Proxy Configuration window by running the proxyconfig-gtk command in the terminal.
# First, we need to specify the type of script we are using, which is bash.
#!/bin/bash
# Next, we call the proxyconfig-gtk command to open the Proxy Configuration window.
proxyconfig-gtk
# Finally, we add a comment to explain the purpose of the script.
# This script is used to open the Proxy Configuration window for configuring proxy settings.
3. Follow the on-screen instructions to configure your proxy server settings, and click “Save” when you’re done.
That’s it! You should now be able to access the internet through your proxy server on Ubuntu Server, without having to edit any configuration files manually, even if you have a complex storage system set up.
But wait! What if you want to add SSH keys during installation? Well, Ubuntu Server has got you covered there too! During the initial setup process, you can choose to import your SSH keys from Github or Launchpad by selecting “Import Username” and entering your username. This will allow you to login password-less on your first login!
However, if you’re setting up a storage system for your Ubuntu Server, there is an additional step that needs to be taken before configuring the proxy settings:
1. Create a software RAID (md) or volume group (LVM). This can be done during the installation process by following the prompts in the Storage configuration section of the setup wizard.
2. Once your storage system is set up, you can proceed with configuring the proxy settings as described above.
3. Restart any applications that need to use the new proxy settings (e.g., Firefox or wget).
That’s it! You should now be able to access the internet through your proxy server on Ubuntu Server, without having to edit any configuration files manually, even if you have a complex storage system set up.
