Squid - upgrade and install howto

If you are currently running a rpm-based squid binary, and you have just made a fresh fedora installation, here's an on how to upgrade and install your currently running Squid proxy web caching server.

By definition:
Squid is a high-performance proxy caching server for Web clients, supporting FTP, gopher, and HTTP data objects. Unlike traditional caching software, Squid handles all requests in a single, non-blocking, I/O-driven process. Squid keeps meta data and especially hot objects cached in RAM, caches DNS lookups, supports non-blocking DNS lookups, and implements negative caching of failed requests

PACKAGE VERIFICATION:
~~~~~~~~~~~~~~~~~~~~~

# rpm -qa squid


SQUID INSTALLATION
~~~~~~~~~~~~~~~~~~

# yum -y install squid


SQUID UPGRADE
~~~~~~~~~~~~~~

# yum -y update squid

Remember that doing yum downloads and installs squid binary with all default compile arguments. If you wish to have a customized compile arguments, you need to download the latest stable tar ball squid.

One of my next entries would discuss more of customizing squid configuration file.
