MySQL wouldn't restart after updating via CustomBuild

(Posting this in case others have the same problem.)

The error message was cryptic:

Starting MySQL. ERROR! The server quit without updating PID file

I tried running mysqld_safe -v, but that just gave

mysqld from pid file ended

Finally, I tried mysqld-debug, which was more helpful:

error while loading shared libraries: libnuma.so.1: cannot open shared object file: No such file or directory

It turns out libnuma is part of numactl, so

yum install numactl

fixed the problem and now mysqld starts.

Thank you so much. You just saved my day!

I though Numa was needed for Mysql 5.7, but seems for 5.6.38 also.
