Installing Squid—a caching agent

To install squid, we will use the zc.recipe.cmmi recipe (http://pypi.python.org/pypi/zc.recipe.cmmi) and plone.recipe.squid recipe (http://pypi.python.org/pypi/plone.recipe.squid).

In 06-deployment-optimization-squid.cfg, we have:

[buildout]
extends = 06-deployment-optimization-varnish.cfg
parts += 
    squid-install
    squid

[squid-install]
recipe = zc.recipe.cmmi
url = http://www.squid-cache.org/Versions/v3/3.0/\
  squid-3.0.STABLE21.tar.gz

[squid]
recipe = plone.recipe.squid:instance
cache-size = 1000
daemon = ${squid-install:location}/sbin/squid
backends = 127.0.0.1:8080
bind = 127.0.0.1:3128

Now stop Varnish and run Buildout:

$ bin/buildout -c 06-deployment-optimization-squid.cfg

Next, be sure to create some cache swap directories for Squid, with the following command:

$ bin/squid -z 

You should see:

$ bin/squid -z

Next, start Squid in the foreground (with –N), as shown:

$ bin/squid -N

Now, browse...
