Thank you for responding.
I was using CentOS 8 already. This was a new installation of CentOS 8 in January and so far it has been running very well. There are occasionally some small software updates but yesterday's took a while so I suppose it was a larger update than usual.
When I run
./ctlscript.sh start mysql starts without issue but apache fails to start, with the message above.
find / -name libk*crypto.so* yields:
OpenSSL 1.1.1c FIPS 28 May 2019
yum install krb5-libs and got the response:
Package krb5-libs-1.17-18.el8.x86_64 is already installed.
Dependencies resolved. Nothing to do. Complete!
Please let me know if you need more information. Thanks for looking into this.
