Mysqldump executed by Virtualmin 4.16.gpl (database backup, virtual server backup, GUI or command line) is failing routinely for me, although I can manage databases from Virtualmin. I have read all threads I can find on this.
I have set the root password in /etc/webmin/mysql/config and checked that I can dump the databases using 'mysqldump' from command line (outside Virtualmin) with the same root password. I have checked the path to /usr/bin/mysqldump: anyway it was working previously.
The most frustrating part is that there is no error message apart from 'Database backup failed : mysqldump failed :
Warning: Using a password on the command line interface can be insecure.'
can you help?
(config file follows)
stop_cmd=/etc/init.d/mysql stop >/dev/null 2>&1
start_cmd=/etc/init.d/mysql start >/dev/null 2>&1 &
