Today, I read about the difference the two directories sites-available
and sites-enabled. Likewise of mods-available and mods-enabled.
sites-available contain all the configuration files that may be active
or not whereas sites-enabled as it name suggest contain enabled or
active sites. We should never edit files in the sites-enabled
directory as it may create problem.
To manage the two directories simultaneously, edit the files in the
sites-available and create symlink in the sites-enabled. After that
run the command
$a2ensite abc.com
Similarly, substitute a2ensite with “a2enconf” for configuration file
and for .load file with “a2enmod”
Apart from this I tried to create passport size photograph and arranged it in a sheet using the online tools.
