To install RunCloud successfully, you need to meet the following requirements:
- Your VPS must be fully installed and initialized before you run the RunCloud installation script.
- Your VPS must be a fresh instance with no pre-existing software on it. RunCloud will not work on a VPS that has other web servers or control panels installed.
- Your VPS firewall must allow incoming and outgoing TCP traffic on ports 22, 80, 443, and 34210.
- If you are using a manual installation script, you must enter the correct root password when prompted by the RunCloud installation script.

Additionally, please ensure your server meets the following requirements:
- OS: Ubuntu 20.04, 22.04, or 24.04 (64-bit LTS)
- Hardware: 1+ CPU Core, 2GB+ Disk Space
- Network: Public IPv4 Address (NAT is not supported)
- RAM: For the best performance, you need to choose the RAM configuration based on your site’s needs. We recommend 1GB as a minimum for small sites and 2GB or more for production applications with significant traffic, caching, or backups.
If you are stuck at 100% during installation, please check that you have met all the requirements above. If you have, you can try to delete the server on RunCloud and reinstall it again. If you are still experiencing installation issues, please get in touch with our support team by opening a ticket.
