It means that httpd isn't running. You should probably try it again using "apache" as the string you grep for. The closest Mint machine I have is in another room (and firewalled off) but all the Debian and Ubuntu machines I can get to right now use "apache2" as the executable for the web server, not "httpd".
If you haven't already, type
- Code: Select all
sudo /etc/init.d/apache2 start
and then try
- Code: Select all
ps ax | grep apache2
