Description:
When using the MySQL Cluster Installer on FreeBSD to define hosts, I get a "No such file or directory '/proc/meminfo'".

In some Linux® distributions, one could look at /proc/meminfo to determine hardware memory information. However, in FreeBSD, sysctl(8) is instead used to view this and other system settings.

How to repeat:
Download:
https://dev.mysql.com/get/Downloads/MySQL-Cluster-8.0/mysql-cluster-8.0.13-dmr-freebsd11-x...

Run ndb_setup.py

Navigate to the https://hostname-or-ip:8081/welcome.html 

Add a FreeBSD host to the host list

The error should pop-up.

Suggested fix:
For FreeBSD 11, use sysctl to query baseline information from hardware such as memory information. 

man sysctl

shell> sysctl hw.physmem hw.usermem hw.realmem
hw.physmem: 500740096
hw.usermem: 468082688
hw.realmem: 536805376

Another workaround is to add the following line to the FreeBSD /etc/fstab:

linprocfs   /proc   linprocfs   rw   0   0
