Por lo que me puse a configurarlo, pero usando Lihttpd en vez de Apache. Aquí van los pasos que realice:
Enable CacheManager Instalar Lighttpd – Configurar CGI – Activar Squid CacheMgr
1.1 Install lighttpd
1.1.1 cd /usr/ports/www/lighttpd
1.1.2 make install – not clean necesitaremos scripts desde los sources
1.2 Config lighttpd.conf
1.2.1 server.document-root = "/usr/local/www/data"
1.2.2 Create document-root dir
1.2.2.1 mkdir -p /usr/local/www/data
1.2.2.2 chown -R www:www /usr/local/www/data – Change owner
1.2.3 server.port = 8180
1.3 Create files that no exist
1.3.1 Create file server.errorlog = "/var/log/lighttpd.error.log"
1.3.1.1 touch /var/log/lighttpd.error.log
1.3.1.2 chown www:www /var/log/lighttpd.error.log
1.3.2 Create file accesslog.filename = "/var/log/lighttpd.access.log"
1.3.2.1 touch /var/log/lighttpd.access.log
1.3.2.2 chown www:www /var/log/lighttpd.access.log
1.4 Config lighttpd.conf for CGI support
1.4.1 Enabled lighttpd modules
1.4.1.1 server.modules = ( "mod_alias", "mod_access","mod_cgi","mod_accesslog" )
1.4.2 Add .cgi extension to exclude static content
1.4.2.1 static-file.exclude-extensions = ( ".php", ".pl", ".fcgi", ".cgi" )
1.4.3 Add alias to a cgi-bin dir
1.4.3.1 alias.url += ( "/cgi-bin" => "/usr/local/www/data/cgi-bin" )
$HTTP["url"] =~ "^/cgi-bin" { cgi.assign = ( "" => "" )
dir-listing.activate = "enable" }
1.4.4 Test file sintax 1.4.4.1 lighttpd -t -f /usr/local/etc/lighttpd.conf
1.5 Create boot script
1.5.1 Copy and Set vars for lighttpd.conf
1.5.1.1 cp /usr/ports/www/lighttpd/files/lighttpd.sh.in /etc/rc.d/lighttpd
1.5.1.2 chmod ug+x /etc/rc.d/lighttpd
1.5.1.3 Set : ${lighttpd_enable="YES"}
1.5.1.4 Set: : ${lighttpd_conf="/usr/local/etc/lighttpd.conf"}
1.5.1.5 Set : command=/usr/local/sbin/lighttpd
1.5.2 Enabled lighttpd in boot time
1.5.2.1 vi /etc/rc.conf add lighttpd_enable="YES"
1.6 Conf SQUID for Cachemgr.cgi
1.6.1 Check SQUID options
1.6.1.1 acl manager proto cache_object
acl localhost src 127.0.0.1/32
acl webserver src 192.168.1.0/255.255.255.0
http_access allow manager localhost
http_access allow manager webserver
cache_mgr smith@localdomain (user for login into cachemgr)
cachemgr_passwd tu_password all (pass for login into cachemgr)
1.7 Conf /usr/local/etc/squid/cachemgr.conf
The access configuration file defining which Squid servers may be
managed via this cachemgr.cgi program.
1.7.1 Add squid.conf http_port
1.8 Restart squid and lighttpd
1.8.1 /etc/rc.d/lighttpd restart; /etc/rc.d/squid restart
Luego se debería acceder desde el browser a la dirección del cache http://ip-cache:port_lighttpd/cgi-bin/cachemgr.cgi
Luego con los datos subministrados anteriormente al squid.conf deberiamos logearnos.
