- Both servers (S1 and S2) are identical.
- Both of them have two network interfaces - one for Main IP which is visible from outside, and one for local IP for interconnection (heartbeat monitoring, MySQL Replication)
- DB are synchronized over MySQL Replication
- LinuxHA heartbeat monitors servers, e.g.
- When S1 fails - S2 sees that and after 10s (default) will take main IP, e.g. will start to serve calls, it is done automatically
- When S1 is back up - S2 returns main IP to S1 and system starts to function in normal work flow (done automatically).
