My site is working on one web server (Apache+PHP, linux OS) and one DB server (MySQL) and it is facing a lot of traffic. I am planning to add additional web server beside the current one. I did not have experience with multiple web server setup so I need suggestions, advices or ideas about the best setup for two web servers.
Here some nice statistics about current web server:
The current Apache configuration is the following:
<IfModule prefork.c> StartServers 8 MinSpareServers 5 MaxSpareServers 20 ServerLimit 1556 MaxClients 1556 MaxRequestsPerChild 2000 </IfModule>
