So, the heartbeat cluster shall manage that both are ok and also check that
the virtual ip and the kamailio service in the primary server is OK....if
something fails it will activate the virtual IP address and the kamailio
process in the other server? so this heartbeat cluster is installed in both
kamailio servers?
which HA software do you recommend?
Do you mean that both Kamailio-1 and Kamailio-2
will be as primary
server?
and the clients will register in the 2 machines?
and also they will bind
to
the ip of the HA? sorry my friend but i do not
understand very well, i'm
quite new with redundant systems, could you please explain a little
please?
Two Kamailios in a HeartBeat cluster which manages the kamailio
service along with a virtual IP in which kamailios are supposed to
listen. Just one kamailio is running (HA manages them).
Regsitration can be done in a shared database with
db_mode=3 (or 2) so
no locations are lost when HA stops the running instance of kamailio
(or the server is down) and starts kamailio in the other cluster node.
So, the database of the kamailios should be dedicated and externalised
server?
Another option without using realtime DB storage is
replicating the
REGISTER from one Kamailio to the other (t_replicate method) but it
requires both kamailios being running at the same time (so
net.ipv4.ip_nonlocal_bind must be 1) and kamailios must NOT be managed
by HA. Also it requires some other considerations.
