Before setting up cURL, you should prepare your system. This includes updating your operating system to the latest version. This preparation ensures a stable environment and helps avoid issues during or after installation.
To make sure your system runs the latest software and security updates, start by performing a system update. Enter the following command:
sudo apt update && sudo apt upgrade -y
This ensures your system has the latest security patches and software versions before installation.
Once the necessary preparations are complete, you can start installing cURL. Run the following command:
sudo apt install curl -y
cURL does not require traditional configuration but can be customized via a configuration file. In this file, you can define default options that are automatically applied with every call. Common examples include:
--user-agent "MyAgent/1.0" to set a custom user agent--silent to suppress progress or extra output--insecure to disable SSL certificate checks (recommended for testing only)--header "Authorization: Bearer <TOKEN>" for API authenticationAdditionally, environment variables like HTTP_PROXY or HTTPS_PROXY can be set to route cURL requests through a proxy server. This makes cURL more efficient for recurring tasks since you don’t have to re-enter long command options each time.
Congratulations! You have now successfully installed and configured cURL on your VPS/Dedicated Server. We also recommend checking out the following resources to help with server configuration:
