Configuring, Tuning and Debugging Apache

RPMs, mod_perl, apachectl, telnet, mod_status, DSO, apxs, Apache::Status...Scared yet? Mr. Lerner tells us about all of these so we can better manage our web servers.

Apache is a wonderful, robust and easily configurable HTTP server. However, it is also a complex piece of software that requires some experience in order to tune correctly. When mod_perl is added to the mix, the complexity increases even more. Luckily, it is possible to install Apache such that installing and upgrading modules can be easy and painless.

Moreover, a number of modules and tools (such as mod_status and Apache::Status) make it possible to view the internals of Apache as it is executing. By taking advantage of these tools, we can find and fix problems with our servers, spending our time on more interesting issues than trying to figure out why a server does not run.
