Hello,
I have created a "homemade" mysql master/slave script and now I am testing
it. For now I think it is OK. I still continue testing it and for me I
think it is OK.
The script control the state of servers with semaphore files because the
two servers are in Master/Master config but only one can be considered as
master.
Master/Master config is not multistate, so a regular resource
should suffice here. Or perhaps I didn't understand this
correctly.
I have Mysql circular replication. With this configuration recovery
is more simple.
If you want to test it, you can download from:
http://code.adrianchapela.net/heartbeat/mysql_slave_master
Using status files can be tricky. Better to put them in
$HA_RSCTMP (/var/run/heartbeat/rsctmp) because this directory is
cleaned on heartbeat start.
Yes I know but I can't do better for now... :D. This directory could be
a better option to write status files. Have you some other idea to gets
status control ?
A small readme file with a simple example rule:
http://code.adrianchapela.net/heartbeat/mysql_slave_master.README
>From the readme:
This script has a attrd variable wich can set two values.
Value 0: when the instance isn't a master
Value 1: when the instance is a master.
The question is which instance? Or, more precisely, if there's
only one variable of a boolean kind, then you can determine if
there's a master but not which node is the master.
This value is used by heartbeat constraints . With this value you only
know if the node is a master or not but only in the same machine.
If you want to contribute the script, please talk to Alan.
Yes I want but I hink this script is very poor now, not ??
Thanks,
Dejan
Best regards.
