Obtain Media ### Obtain Media
If you are new to Linux or new to CentOS minimal installations, I would advise reviewing all the information at the URL below. Otherwise, scroll down and select the download URL under section 2. We will be using x86_64 version, also, known as 64 bit. The 32 bit version *should* work as well.

Installation ### Installation
Boot from media and, generally, accept the defaults. You have an opportunity to provide time zone, a host name, configure network interfaces, provide DNS IPs, and domain search. If configured at this point, the installation script automatically configures the resulting installation using these settings. It is a time saver, however, I am going to assume either these setting have not been set or changes will be needed. Boot from media and, generally, accept the defaults.

Time Zone
After installation, the default time zone is America/New_York. Changing the time can be done several ways. My preference is to first identify the time zone by listing /usr/share/zoneinfo.
