What Types Of Problems Are Typical?

While atypical problems sometimes arise, the vast majority of the problems you face when trying to get your website to work fall on a very predictable spectrum.

We’ll look at these in more detail in the following sections. For now, here’s a simple checklist to watch out for:

  • Is your web server installed?
  • Is the web server running?
  • Is the syntax for your web server configuration files correct?
  • Are the ports you configured open (not blocked by a firewall)?
  • Are you entering DNS settings correctly?
  • Does the document root point to the location of your files?
  • Is your web server providing the correct index files?
  • Are the access rights correctWhoa and ownership of the file and directory structure?
  • Are you restricting access via config files?
  • If you have a database backend, does this work?
  • Can your site successfully connect to the database?
  • Is your web server configured to deliver dynamic content to the scripting engine?

These are some of the most common problems that administrators face when a site is not working properly. The exact problem can usually be resolved by looking at the log files for the various components and referring to the error pages displayed in your browser.

We’ll cover each of these scenarios below so you can make sure your services are configured correctly.
