Squid adalah salah satu dari banyak proxy server yang banyak digunakan di dunia. Tutorial ini adalah kelanjutan dari tutorial untuk Ubuntu dan Debian.

Instalasi Squid

su -c "yum install squid"

File konfigurasi squid berada di /etc/squid/squid.conf, hapus semua isi squid.conf dan tambahkan dibawah ini kedalamnya

#
# Recommended minimum configuration:
#
 
# Example rule allowing access from your local networks.
# Adapt to list your (internal) IP networks from where browsing
# should be allowed
acl localnet src 10.0.0.0/8	# RFC1918 possible internal network
acl localnet src 172.16.0.0/12	# RFC1918 possible internal network
acl localnet src 192.168.0.0/16	# RFC1918 possible internal network
acl localnet src fc00::/7       # RFC 4193 local private network range
acl localnet src fe80::/10      # RFC 4291 link-local (directly plugged) machines
 
acl SSL_ports port 443
acl Safe_ports port 80		# http
acl Safe_ports port 21		# ftp
acl Safe_ports port 443		# https
acl Safe_ports port 70		# gopher
acl Safe_ports port 210		# wais
acl Safe_ports port 1025-65535	# unregistered ports
acl Safe_ports port 280		# http-mgmt
acl Safe_ports port 488		# gss-http
acl Safe_ports port 591		# filemaker
acl Safe_ports port 777		# multiling http
acl CONNECT method CONNECT
 
#
# Recommended minimum Access Permission configuration:
#
# Only allow cachemgr access from localhost
http_access allow localhost manager
http_access deny manager
 
# Deny requests to certain unsafe ports
http_access deny !Safe_ports
 
# Deny CONNECT to other than secure SSL ports
http_access deny CONNECT !SSL_ports
 
# We strongly recommend the following be uncommented to protect innocent
# web applications running on the proxy server who think the only
# one who can access services on "localhost" is a local user
#http_access deny to_localhost
 
#
# INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS
#
 
# Example rule allowing access from your local networks.
# Adapt localnet in the ACL section to list your (internal) IP networks
# from where browsing should be allowed
http_access allow localnet
http_access allow localhost
 
# And finally deny all other access to this proxy
http_access deny all
 
# Squid normally listens to port 3128
http_port 3128
 
# Uncomment and adjust the following to add a disk cache directory.
#cache_dir ufs /var/spool/squid 100 16 256
 
# Leave coredumps in the first cache dir
coredump_dir /var/spool/squid
 
# Add any of your own refresh_pattern entries above these.
refresh_pattern ^ftp:		1440	20%	10080
refresh_pattern ^gopher:	1440	0%	1440
refresh_pattern -i (/cgi-bin/|\?) 0	0%	0
refresh_pattern .		0	20%	4320
 
cache_dir ufs /var/spool/squid 4000 16 256

Proxy ini bisa digunakan oleh siapa saja karena tidak menggunakan hak akses, IP-IP yang bisa mengaksesnya bisa dilihat di file konfigurasi diatas dibawah # should be allowed. Cache squid disimpan di

/var/spool/squid
