====== Change the Memory Limit for PHP Scripts ======
**WARNING:** Always make a backup of php.ini before making changes to it.

If you are doing this as root, you do not need to use 'sudo' at the beginning of the commands.
  - Open your php.ini file. (Most often it is in the /etc/ directory)
      <file>sudo nano /etc/php.ini</file>
  - Locate the following setting:
      <file>memory_limit '' 8M ; Maximum amount of memory a script may consume (8MB)</file>
  - Replace the '8M' with the desired setting, ie Cacti recommends 512M or better.
  - Press 'Ctrl+O' and then 'Enter'.
  - Press 'Ctrl+X' to exit.
  - Restart Apache Server with the following command:
      <file>sudo /etc/init.d/httpd restart</file>
