Hello,

Is anyone able to confirm whether the cluster definition I provided should indeed do what I think it should? If so, I will take a look further myself to find the reason why not.

Thanks in advance,

Charles

Hi All,

I'm having difficulties with the above module and can't see what I'm doing wrong.

Config as follows:

modparam("db_cluster", "connection", "db01=>mysql://readwrite:password@db01.domain.com/kamailio")
modparam("db_cluster", "connection", "db02=>mysql://readonly:password@db02.domain.com/kamailio")
modparam("db_cluster", "cluster", "cls1=>db01=0s9s;db02=9s0s")

As you can see, there are two database servers - a master and a slave. I am trying to force all read operations to the slave (db02) and all write operations to the master (db01).

Unless I am missing the point, the above priorities should achieve the desired effect. However, it seems to be going wrong somewhere as write operations are being sent to the slave:

ERROR: db_mysql [km_dbase.c:122]: driver error on query: DELETE command denied to user 'readonly'@'x.x.x.x' for table 'location'

ERROR: db_mysql [km_dbase.c:122]: driver error on query: UPDATE command denied to user 'readonly'@'x.x.x.x' for table 'location'
ERROR: db_mysql [km_dbase.c:122]: driver error on query: INSERT command denied to user 'readonly'@'x.x.x.x' for table 'location' 

It is the same for all modules, by the way, not just usrloc. For each module, I have db_url set to "cluster://cls1".

If I change the cluster definition to "cls1=>db01=9s9s;db02=0s0s", all operations (read and write) are sent to db01 as expected.

Am I missing something here? Can anyone see what I may be doing wrong?

Many thanks,

Charles
