standby web server

pinecone
have a couple of apache 2.2 servers. one is primary - the other is a copy. is there a mechanism in v7.x to configure them for automatic failover should the primary go offline?

thanks in advance...

    No.

    Astaro did, and maybe still does, have a very simple load balancer, but it was round-robin only and had no sensitivity to load or outages.

    FYI, there are some free Linux/UNIX based load-balancing programs.

    Or you can use "heartbeat", a linux/unix program which watches a master server, and if it dies, promotes a slave to master, by taking over the IP address of the master.

    I think Astaro uses heartbeat within their hot-failover system.

    Another option would be a reverse http proxy, such as Squid in reverse mode.
