Repair, test, and optimize all MySQL databases via SSH:

mysqlcheck --all-databases -r #repair
mysqlcheck --all-databases -a #analyze
mysqlcheck --all-databases -o #optimize 

Get a listing of file sizes recursively to see if there are only a few files eating up disk space. Tested in CentOS 6:

du -k | sort -n | perl -ne 'if ( /^(\d+)\s+(.*$)/){$l=log($1+.1);$m=int($l/log(1024)); printf ("%6.1f\t%s\t%25s %s\n",($1/(2**(10*$m))),(("K","M","G","T","P")[$m]),"*"x (1.5*$l),$2);}'

Find files older than X number of days and delete them. Remove the -delete to only list them. X number of days changed with the +7

find /folder/to/check/recursively -type f -mtime +7 -delete -print

Step 1 – Log in to your cPanel account by pointing your browser to cpanel.your-domain.com Enter your username and password, you should get these credentials from your hosting company.

Step 2 – Find the box labeled “Mail” and click the “Forwarders” icon.

Step 3 – You will see a list of existing forwards. If you wanted to delete one then this would be the place to do it. Right now we want to create a new one so click the “Add Forwarder” button.

Step 4 – Fill in the first part of the new email address(example: test) and choose the domain this address will be under. Next fill in the forward to email address field with the full address of the account where you want to get the mail. Make sure the radio button next to that field is selected and click “Add Forwarder”

That’s pretty much it, once the mail server receives an email to that address it will turn around and send it to the forwarding address.

Luckily setting up a new email address for your domain name is incredibly easy if you have a cPanel host and today I’m going to show you how to do it.
