Limit on total number of servers running: Limit on the number of clients who can simultaneously connect. If this limit is ever reached, clients will be `locked out', so it should not be set too low. It is intended, mainly, as a brake to keep a runaway server from taking the system with it as it spirals down.

MaxClients 150

MaxRequestsPerChild: The number of requests each child process is allowed to process before the child dies. The child will exit so as to avoid problems after prolonged use when Apache (and maybe the libraries it uses) leak memory or other resources. On most systems, this isn't really needed, but a few (such as Solaris) do have notable leaks in the libraries. For these platforms, set to something like 10000 or so; a setting of 0 means unlimited.

NOTE: This value does not include keepalive requests after the initial request per connection. For example, if a child process handles an initial request and 10 subsequent "keptalive" requests, it would only count as 1 request towards this limit.

MaxRequestsPerChild 100

Listen: Allows you to bind Apache to specific IP addresses and/or ports, in addition to the default. See also the directive.

Listen 3000

Listen 12.34.56.78:80

BindAddress: You can support virtual hosts with this option. This directive is used to tell the server which IP address to listen to. It can either contain "*", an IP address, or a fully qualified Internet domain name.

BindAddress *

Well that's all for now. In the second part we shall look into Dynamic Shared Object (DSO) Support and also 'Main' server configuration.
