/usr/lib64/httpd/modulesThe httpd package we installed includes the config file:
/etc/httpd/conf/httpd.confListening on a Port

Setting the Document Root
The DocumentRoot defines the top-level directory of the web site
Setting an Identity

Defining Multi-Process Settings
To improve response times, apache manages a pool of “spare” server
processes
These numbers control the size of the pool:
| StartServers | 8 |
| MinSpareServers | 5 |
| MaxSpareServers | 20 |
| ServerLimit | 256 |
| MaxClients | 256 |
Containers
Container directives use XML-style opening / closing tags
