Replication of 2 ubuntu servers?

Question

replication

Good afternoon,

Tell me, how can I configure full replication between 2-3 servers (of the entire server) in Ubuntu?
Can this be done with Redis?

Thank you!

Answer 1

Nobody usually replicates the "whole server", this is done for specific components, and, depending on their specifics, in different ways. You can set up a distributed file system, but for a DBMS, for example, this type of replication is not suitable, because it does not provide data consistency.
