User moonsplit is having trouble installing Discourse on their Ubuntu VPS hosted on OVH. They followed a tutorial but still can’t get Discourse to run. RGJ asked for more specific details about the issue, while Simon_Manning suggested that the problem might be due to using a LAMP image when creating the VPS, recommending a base Ubuntu image instead. pfaffman pointed to the official Discourse installation guide. moonsplit revealed that they manually installed Apache and MySQL during the process. pfaffman and merefield explained that this is the likely cause of the issue, as Discourse uses nginx instead of Apache, and suggested starting fresh or uninstalling Apache to resolve the problem.
The page shown at that domain looks like a default page provided by some other web server software (Apache, I think) which might mean you’ve created your VPS using a LAMP image.
When you created the VPS, did you choose an option that mentioned anything about hosting websites? If so, it may be worth recreating the VPS with a different image, a base Ubuntu image which doesn’t include any software for web hosting.
If you follow the recommended installation process you can’t have another web server installed so you would need not to have apache. There are topics about installing discourse with other web servers.
