I'm following along with this article https://www.digitalocean.com/community/articles/how-to-install-rails-and-nginx-with-passenger-on-ubuntu. 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: /opt/nginx But it can't do that, because you're running the installer as michael. Please re-run this installer as root.
