Как обеспечить удаленный доступ к MySQL для root
Итак мы хотим, чтобы root мог влезть в любую базу данных откуда угодно (просто рай для хакеров).
Во-первых, добавляем привилегии root
|
1 |
grant all privileges on *.* to 'root'@'%' identified by 'secret-password' |
Во-вторых, комментируем строчку в /etc/mysql/mysql.conf.d/mysqld.cnf
|
1 |
#bind-address = 127.0.0.1 |
В третьих, перезапускаeм MySQL
|
1 |
/etc/init.d/mysql restart |
Удаленный доступ работает (ниже пример, взятый с бескрайних просторов)
