How to install MariaDB Galera without internet connection( without YUM)?
Hi guys,
I want to install a HA ( high availability ) environment without internet, but I am a rookie. Most webs, I can't find relative information how to do this job.
First, how to do with step by step instructions, please? Second, is it correct that I must have 4 PCs ( 3 cluster nodes and 1 HA proxy)?
Answer Answered by Daniel Black in this comment.
You need 3 cluster nodes minimum to determine quorum. HA proxy can be on one or more of these nodes. Note a 1 HA node proxy becomes a single point of failure.

Exact deployment will depend on requirements. Get professional help if you are out of your depth. Various blogs on galera and HA have been written and transcribing those to a comprehensive step by step guide is beyond the level I'm willing to write up.
