In am running a 24/7 monitoring system based on PHP, I was asked to make minimum downtime. So i need your advise.
I have a 4 servers and 1 storage. All servers are in Vsphere cluster. So if one goes down active node takes up to 3 min to start. I want to have 0 downtime. Besides the hardware cluster i want to create a software:
Apache and MYSQL cluster.
So lest say i have 2 servers, both have Uniform server installed as a service, i want them automatically to synchronize MYSQL and Apache Data.
Can you please advise me the best approach.
My idea was to install some file synchronizer 2 way enabled for Apache
And MYSQL cluster for windows
But maybe there is some better way?
