/etc/init.d/[service] [operation]

This "pathname" is actually a script that causes the initiate daemon (that constantly stays in memory) to act on a service that has been input. After the service, an operation can be input in from one of the following:

  • start
  • stop
  • reload
  • restart
  • force-reload

For our purposes, the only services that we know that this script can act on are as follows:

  • nginx
  • mysql
  • php5-fpm

/etc/hosts.deny

This file can be accessed via pico or any other text editor in order to manage the IP addresses that have been blocked from accessing your virtual machine (including your own if it accidentally happens). Once you are in the file, delete the IP address (possibly your IP address) at the bottom of the file that you no longer wish to restrict.
