A few things we have noticed recently when it comes to Galera Manager support requests, that we feel we should address in this blog post.

This means you install the base operating system and nothing else: no Nginx, no Apache, no InfluxDB, etc. The Galera Manager installer (gm-installer) will pull all the requisite packages, set SELinux to permissive during the install, etc. The next release of the gm-installer aims to be less fragile when it comes to this, and will aggressively handle installs on machines that already have software installed on it.
