====== Installing Squid with Vufind in 10 minutes ======


Due to Syndetics network/service issues, Western Michigan University implemented a reverse proxy cache for particular third party venders.  Squid [http://www.squid-cache.org/] is an opensource reverse proxy cache. It can cache and store third party content locally, thus improving response times.

 
In our case, we use a separate server to increase performance. Squid can either be installed on the Vufind server or separately.  However, due to its system load, it is recommended that Squid be installed on a secondary machine*.  In these instructions, the base operating system is RedHat 5.2/CentOS [http://www.centos.org/].
======== Install the Operating System ========
    * Large Partitions
    * Swap should be 2x or more of RAM
======== Update System ========
    *[root@Squidbox] yum update -y
======== Reboot into new Kernel ========
    *[root@Squidbox] reboot
======== Open Squid Port 3128 ========
    *[root@Squidbox] setup
    *Follow GUI

======== Install Squid ======== 
    *[root@Squidbox] yum install squid -y
======== Configure Squid ========
    *replace this with the /etc/squid/squid.conf
Note 1: 165.254.62.247 is the IP of syndetics.com
Note 2: 3128 is the default port

======== Add Squid as a Service ========
[root@Squidbox]/sbin/chkconfig --add squid
======== Start Squid ========
[root@Squidbox]/sbin/service squid start


Note: Currently (1.0RC1), you must go through and hand edit bookcovers.php, Record/Review.php, and Record/Exercpt.php and replace http://syndetics.com with yoursquidboxip.  I did submit a patch to allow easier setup.
