When encountering the “DSN ‘plesk’ is invalid” error during Plesk installation, you’ll want to ensure that the Database Server Name (DSN) is correctly configured. Here’s how you can troubleshoot and potentially fix this issue:

1. Verify Database Configuration: Double-check that the database server name (DSN) provided during the installation process is accurate. Ensure there are no typos or errors in the hostname or port number.
2. Check Database Connectivity: Make sure the Plesk server can connect to the database server. You can test this using command-line tools like telnet to check if the port is open and ping to verify connectivity to the database server.
3. Database Permissions: Ensure that the database user provided during the installation has the necessary permissions to create and manage databases on the server. It should have privileges like CREATE DATABASE, ALTER, DROP, etc.
4. Firewall Settings: Check the firewall settings on both the Plesk server and the database server to ensure that the necessary ports are open for communication between them.
5. DNS Resolution: Ensure that the hostname of the database server is resolving correctly. You can do this by using tools like nslookup or ping to resolve the hostname to its IP address.
6. Review Installation Logs: Check the installation logs for any specific error messages related to the DSN validation failure. These logs should provide more details about what went wrong during the installation process.
7. Consult Plesk Documentation or Support: If you’re still unable to resolve the issue, consider consulting the official Plesk documentation or reaching out to their support team for assistance. They may have specific troubleshooting steps or solutions for this error.
