need some guide to host a domain with out downtime

[cmdman]

hi mr

i got a small project to do i have a domain myserver.com i need to make this server HA or what ever ,site should not go offline at any time

We have servers in 3 different locations, different ISP and with multiple IP`s is it possible with Kloxo-mr

site is not big application just webapplication with out sql db, but big traffic every day may be 50 to 70k visits

[cmdman]

any idea please how it can be done

Kloxo-MR 6.5 have some limitation for this situation (example need manual optimize for php-fpm).

[cmdman]

either 6.5 or 7.0 i need that site should never goes down and this is just webapp no sql db just html site huge users visits

please tell me how i can do it with 3 server with different locations

[MRatWork]

No special treatment. Just install Kloxo-MR 7.0 in all servers. Just add server2 and server3 in server1 if want master-slave system.

[cmdman]

Site design

Server 1- kloxomr 7.0 IP - 193.45.56.11
Server 2- kloxomr 7.0 IP - 193.45.56.12
Server 3- kloxomr 7.0 IP - 193.45.56.13

in server 1 i create domain as mydomain.com and upload site files  how about others server what need to do incase my server 1 is down because of some issues or datacenter down how site will work from other servers ..

[MRatWork]

In website side, we can sync database with mysql cluster. For website content, we can sync with simple bash code periodically.

The problem is dns side because dns refer to 'single' ip for __base__ address (IP). So, we need switch/change IP if one 1 IP down.

Another scenario is using load-balancing where 1 server as front and and just install nginx/hiawatha and other servers as backend data.

You need IP failover to achieve this.

You need IP failover to achieve this.

Yes, server for this forum using IP failover to minimize downtime (because no need re-propagation DNS).
