Hi
We have configured maxscale in our environment using the links
http://karlssonondatabases.blogspot.in/2014/02/maxscale-for-rest-of-us-part-1.html,
2, 3 . We have two slaves and one master and the replication between them
is working well. But after configuring read/write split the select queries
are being executed in master itself, not routing to the slaves. Please find
the attached documents of maxscale configuration, maxscale commands
maxscale log and. Please help with maxscale read/write split.
Attached documentsdetails
1. maxsconf.txt from the location /etc/maxscale.cnf
2. maxscale-commands.txt, coomands like maxadmin -pmariadb list
servers, maxadmin -pmariadb list services, maxadmin -pmariadb show service
"Splitter Service",
3. maxscale-log.txt from /var/log/maxscale
Thanks
Chaitu
