Dear Till & Falko, For one of my Debian Etch servers with ISPConfig (server 1), i want to setup a mirror server (server 2). So, In case server 1 fails/crashes, server 2 takes over server 1 with a minimum of downtime. I was thinking about using DBRD and Heartbeat, but i need a little help to setup such a system or a Howto on howtoforge which i can use. Of course, I have seen that there are some Howto's available, but these are for Virtual environments, not for real servers. Is there also a guide or howto available, which i can use for real servers? Any help is apreaciated. Kind regards,
That's a difficult topic. Unfortunately, there's no out-of-the-box solution. This might be interesting: http://www.howtoforge.com/high_availability_nfs_drbd_heartbeat http://www.howtoforge.com/mirroring_with_rsync And if you use MySQL 5, take a look here: http://www.onlamp.com/pub/a/onlamp/2006/04/20/advanced-mysql-replication.html
Hi Falko, Well...maybe then my next server will be Debian Etch as the base system with Virtual machines. Which virtual environment do you recommend? XEN, OpenVZ or VMWare or ...? I think Xen is a good choice, but its seems that it is not reliable on 64 bit systems or am i mistaken?
i use rsync to create a mirror server (hardware must be the same) and i only change the network / host confs And i found these 2 links that would be helpful Linux Load Balancing Cluster : http://www.syslog.gr/content/view/7/2/ MySQL Cluster Server Setup HowTo : http://www.syslog.gr/content/view/6/2/
Till told me that you can do live-migration with OpenVZ (i.e., move running virtual machines), so this might be a good choice.
