How to create an Apache/Mysql Failover system?

Question

I am building a web application for a client, using WAMP (Windows. Apache, Mysql , PHP) and have been asked to make the system reliable with automated failover. The web application should automatically go to working backup if the main server dies. Right now the applicaiton lives on one machine, but when the system is put in production a hot (live) stand by server needs to be active. I understand how to do mysql replication, but that alone does not take care of the automatic failover. Does anyone have any ideas?

Answer 1

THere is one that I know, I used it once for the same reason, but you need to deploy your web server on Linux! Anyway there is a signal you application may catch when the system is crashing, or is about to be shut down, This signal may be caught and used by the apache server. I do not rememberthe exc signal and parameters the apache must be started with. But you may check it upon the apache help, best of luck,

fairly lengthy in the past the society replaced into divided into 4 castes based upon the character of provider they accomplish that as that they jointly ensure the graceful working of the social device. It replaced into like the operational divisions of companies. those 4 castes have been the 4 useful pillars on which the society replaced into status. interior the path of time the caste began to get desperate by using delivery and later a number of those sections began thinking themselves better to others. This ultimately delivered approximately the cruelty and inhuman behaviors of untouchability etc. there has been repeatedly cautions from Hindu scholars against those inhuman behaviors. Now this technique is getting phased out and the Hindus could be quickly out of the undesirable style it left.

I would change that to Linux (LAMP) in a heartbeat if I was concerned with reliability. Just an opinion but from years of server management.
