Permission problems installing nginx

  • Posted June 9, 2013

I’m following along with this article At Step 6, I’m getting the following message asking me where I want nginx installed to (I clicked return) and then got an error because I’m running the installer as my name ‘michael’ (which I gave sudo privileges) instead of root.

Can you explain what I’m doing wrong?

Where do you want to install Nginx to?

Please specify a prefix directory [/opt/nginx]:

Permission problems

This installer must be able to write to the following directory:


But it can’t do that, because you’re running the installer as michael. Please re-run this installer as root.

The command on step 6 – sudo rvmsudo passenger-install-nginx-module

But I’m not entering a command (I’m only hitting ‘enter’ when it asks me to specify a “prefix directory”) which is triggering the permissions error. How do I prefix an ‘enter’ with sudo?

Try prefixing the command with "sudo " so it runs as root.
