comment Search-engine friendly DNS redirection
They are not redirects, they are aliases. They handle the way names are translated into addresses, and don't affect what happens to web pages; a CNAME can be used to direct to a server which does virtual hosting and hosts different sites from another CNAME - I've used this technique lots myself.

comment su to user that doesn't exist any longer?
Yes you should be able to temporarily re-create the user; this should not involve editing any files, you can do it with useradd.

comment How fill a database mysql with examples data?
Unfortunately you need to be far more specific than this - what KIND of data to put into which tables - and writing scripts to generate it can be quite an onerous task. I spent three months on this last year.

comment What prevents loops in mysql master-master setups?
Rather, the locking which assures atomicity when using (e.g.) REPEATABLE_READ txn isolation, does not extend to the other node of a master-master - it does not do transactional replication - therefore if both nodes are written to, then situations which would lock or deadlock on a single node, will fail spectacularly and cause either out-of-sync data or a replication error (which mysql does not attempt to recover from automatically)

comment What prevents loops in mysql master-master setups?
In order to tolerate master-master, the application needs to work on the basis that its transactions will have the same (or equivalent) results regardless of the order they are applied AND not fail regardless of the order they are applied, in practice this is very hard to achieve - there are some special cases where it's possible.
