After a reboot httpd fails with the below status.

To take care of that mod_evasive error (from a Qualys IP) I set a log path in /etc/httpd/conf.d/mod_evasive.conf, e.g., DOSLogDir "/var/log/httpd/mod_evasive"

I then found this thread, and set the following in /usr/lib/systemd/system/httpd.service:

PrivateTmp=false
NoNewPrivileges=yes

And then:
systemctl daemon-reload

Also saw this error from mod_security: Status engine is currently disabled, enable it by set SecStatusEngine to On.

So I set SecStatusEngine On in /etc/httpd/conf.d/mod_security.conf.

These seem like work-arounds. Is there a better way to handle these warnings and errors? We are on kernel-5.0.17-300.fc30.x86_64
