There is some additional documentation required when installing Maxscale 2.4.2 on CentOS 7
Output from maxpasswd is placed in the /etc/maxscale.cnf file
The problem is that the /var/lib/maxscale/.secrets file is created as owned by the user who ran the commands rather than maxscale.

Access for secrets file [/var/lib/maxscale/.secrets] failed. Error 13, Permission denied.
It can be fixed with:
The yum install creates the maxscale user but does not advise that you change to that user to perform the other actions.
