Discover a feature that can significantly ease your server setup process on EDIS Global VPS Hosting - Post-Install Scripts. This feature can be found in the auto-installer options within your KVM panel. It's a boon for those installing multiple servers with a specific setup or "recipe". All you need to do is paste your recipe/script or upload it directly into the tool, and it will be executed automatically right after the installation completes.
Below are three example scripts tailored for different operating systems:
The following script was successfully tested on Debian 12. This script performs the following operations on a Debian-based OS (Debian, Ubuntu, Linux Mint, Kali Linux, Raspbian, Pop!_OS, MX Linux, Deepin):
- Disables password authentication for the root user, allowing only SSH key authentication.
- Changes the default SSH port from 22 to 10022 and restarts the SSH daemon to apply the changes.
- Updates the system packages, upgrades existing packages, and installs the components of a LAMP stack (Linux, Apache, MySQL, and PHP).
- Sends a notification through Pushover (a notification service) indicating that the post-installation script has completed, along with the server's IP address.
This below example post install script performs the installation oft a simple firewall. This script does three main things:
- It installs a firewall tool called UFW (uncomplicated firewall)
- It sets up rules in the firewall to allow incoming connections for SSH on port 22, web traffic on port 80, and secure web traffic on port 443.
- It turns the firewall on with these rules in place.
The length of our Post Install Scripts is unrestricted. You can combine and tailor them to create intricate setup processes and streamline your deployment.
The following script performs several actions on a RPM-based OS (RHEL, Fedora, CentOS, openSUSE, SLES, Oracle Linux, Rocky Linux, AlmaLinux)
- SSH ConfigurationIt restricts root login to SSH key authentication only, disabling password access. It then restarts the SSH daemon to apply these changes.
- LAMP Stack Installation: Updates the system packages. Installs necessary utilities: curl, wget, and unzip. Installs and starts the Apache web server, and ensures it starts on boot. Installs and starts the MariaDB server, and ensures it starts on boot. Installs PHP along with some additional modules.
- Notification (optional)Sends a notification via the Pushover service, indicating that the post-installation script has completed and providing the IP address of the server.
The above scripts serve as illustrative examples, showcasing how you can leverage the Post Install Script feature. The potential applications are boundless.
Here are some more examples of tasks you can automate with post-install scripts:
