We are in the process of migrating an overburdened Debian 3.0/Apache/qmail box into a webfarm setup.
Looking at using a ServerIronXL for loadbalancing. Would appreciate anyone's experiences/recommendations on the following points: 1. What is the recommended method to synch config files on all "real" servers (Eg. Httpd.conf, horde/imp config files etc?) - Have only one server that admins connect to for mods, then rsync any changes to the other servers? 2. What about logfiles - We would have all users mail etc on an NFS share - Can you do the same for logfiles?(Or do you get locking issues?) - From a statistical aspect, it would be a pain to have to collaborate each "real" servers logfiles, then run analysis. Also from a support perspective - How are support personnel supposed to know which "real" server a client would actually be connecting to in order to see if they are entering a wrong username/pass etc? 3. Imaging of Servers - I have looked at SystemImager http://www.systemimager.org/, and it looks to do exactly what I want (i.e. be able to create a bootable CD from our SOE for deployment of new serverfarm boxes, or quick recovery from failure) - Can anyone provide feedback as to it's effectiveness? Thanks in advance. Regards, MB
