Hello,
I am trying to make a MySQL system with high availability. One Master
server and one slave server wich will assume the master functions
when the master server goes down.
My problem is to make a rule for the execution in slave server when
master server goes down. When master server goes down, the slave
server assume the VIP and then must execute a script to test
something and then the server can go up but it can't go up until the
first test has finished.
Can you say me how to write this rule ??
Thank you!
Can you give a bit more details on what you've gotten setup so far?
Are you using heartbeat v2? Are you using the /etc/ha.d/haresources
file or CRM? Are you using DRBD?
In my case (still working on DRBD issues) my ha.cf file is:
http://tle-bu.org/misc/ha.cf.vash
And my haresources file is:
http://tle-bu.org/misc/haresources.vash
Do note though that the haresources file above may be broken. As I
mentioned, I am currently working on a DRBD problem. However, the
commented out line (second from the bottom) works fine.
If you can provide more details and/or ask specific questions I might
be able to help you more. At the moment though, I'm still learning as
well, though I have gotten past a few of the early trip-ups.
Madi

Excuse me now. I explain this later, but now I am trying to solve some
doubts with list archive.
In the future I am writing again my doubt or my solution for my problem.
Thank you in advance.
