Attempting to use jemalloc for mysql 5.7.30

Linux db1 4.18.0-193.6.3.el8_2.x86_64 #1 SMP Wed Jun 10 11:09:32 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

MySQL 5.7.30

yum list installed shows: jemalloc.x86_64 5.2.1-2.el8 @epel

jemalloc file evident in /usr/lib64/


malloc-lib=/usr/lib64/ my.cnf returns an "unknown variable" error for malloc-lib


in the systemctl override file doesn't change anything

Manually doing

export LD_PRELOAD=/usr/lib64/

prior to a restart doesn't have any effect either.

What am I missing?
