This is a proposed Canonical Question about Beginning Web Server Administration.

hostnames: meaningful vs meaningless

Assume puppet-managed cluster of different servers – hardware, software, operating systems, virtual/dedicated etc. Would you go for meaningful hostnames (mysqlmaster01..99, mysqlslave001..999, vpnprimary, vpnbackup, etc). Or would you prefer meaningless names like characters from some book or movie w/e? My problem with meaningfull servers is that names usually represent a single service and if server has more than 1 purpose – it gets really messy(especially when server roles change often). Isn’t mapping service name <-> ip […]

ProxyCommand allows you to configure a machine […]
