README for squid 2.5
REQUIREMENTS
PRE-INSTALL
1. Create user/group squid with a unused id < 99:
'groupadd -g 20 squid'
'useradd -g squid -u 20 -d /var/squid -s /bin/false squid'
'passwd -l squid'
POST-INSTALL
1. run '/usr/sbin/squid -z' to build the cache structure
PRECAUTION
1. all directories used by squid must be chown to
squid.squid or to the effective cache user/group defined
in squid.conf
2. With version 2.5 the location of the squid executable has
changed from /usr/bin to /usr/sbin. Don't reject the new
startscript /etc/rc.d/squid.
CONFIGURATION OPTIONS
There are many other configuration options for squid. This
port should be a very basic one, read the docs for the more
advanced options. George Adamopoulos sent me an email with
some suggestions, which I'll not include in the port, but
put here because of his useful comments:
--enable-delay-pools
Enable delay pools to limit bandwidth usage. You need to
enable the option in order to use Squid to limit bandwith
usage. It will give fair bandwith usage for everybody.
In my case, I don't want one person sucking all of the
available bandwidth by downloading a big movie, causing
others to suffer.
--enable-storeio=diskd,ufs
Enable diskd. Improve disk I/O performance. According to
the Squid FAQ, if you enable diskd you can gain a 400%
increase of perfomance. However, you would need to
recompile the kernel because your operating system must
support message queues and shared memory.
--enable-removal-policies
Build support for the list of removal policies.
By default, Squid uses LRU, but there are two better
policies: GDSF and LFUDA. See the Squid config for a more
detailed explanation.
--disable-ident-lookups
Removes code that performs Ident (RFC 931) lookups.
Not really important. By the way, if you do transparent
proxy, ident lookups won't work.
--enable-snmp
You can monitor Squid with mrtg or rrdtool.
