I am following The Perfect Server Guide for Ubuntu 10.04 http://www.howtoforge.com/perfect-server-ubuntu-10.04-lucid-lynx-ispconfig-3-p5 I learned that nginx faster. Can I install nginx later on after I finish setting my server up or do I have to do it before I install ISPConfig3? http://library.linode.com/web-servers/nginx/installation/ubuntu-10.04-lucid
Nginx has to be installed before you install ispconfig 3. I recommend that you redo the installation and use the perfect server guide for ispconfig 3 and nginx this time.
