Do you still have the mysql client programs present (mysqladmin, mysql)
- They provide a distribution-agnostic way of shutting down things.

"mysqladmin shutdown -pSOMEPASSWORD"

If your distribution runs mysqld through mysqld_safe or mysqld_multi
wrapper, send a SIGHUP to the mysqld_safe process, not to individual
mysqld processes.

If you have no apropriate backup you should consider hiring external
advice first.
