The recent upgrades of Cpanel have been a pain because they've broken mysqlhotcopy. Not kosher. Fortunately fixing this is pretty easy, by simply downgrading the DBD module of Perl, which mysqlhotcopy relies on.

Usually the error is something like this:

To solve this, simply downgrade the DBD to version 4.001. Create a script anywhere on your root folder as, say, dbd-downgrade.sh:

1
2
3
4
5
6
7
8
9

#!/bin/sh
cd /usr/src
wget -O dbd.tar.gz  "http://search.cpan.org/CPAN/authors/id/C/CA/CAPTTOFU/DBD-mysql-4.001.tar.gz"
gzip -cd dbd.tar.gz | tar xf -
rm -rf dbd.tar.gz
cd DBD-mysql-4.001
perl Makefile.PL
make
make install

Then of course chmod the file to executable (644) and run it:

Then try your mysqlhotcopy command again. It should work. The only thing to consider is that if your Cpanel is setup to upgrade automatically, it may rebuild DBD. You may need to downgrade the DBD again, until this thing is fixed!

If after this update, you see the error for RELOAD privileges, like this…

DBD::mysql::db do failed: Access denied; you need the RELOAD privilege for this operation at /usr/bin/mysqlhotcopy line 472.

…then simply login to mysql as "root" user through the root SSH terminal, and execute the following command:

mysql>  grant all privileges on *.* to root@localhost;
mysql>  flush privileges;

Done. That should do it. Let me know if it doesn't.

A more long term fix

MySQL bug list has a couple of suggested fixes. If you are comfortable with Perl, you can edit the code in /usr/bin/mysqlhotcopy and have it solved in a better way.
