Konfigurasi proxy server squid sederhana ada di IGNwiki http://igos-nusantara.or.id/wiki/IGOS_Nusantara_dan_proxy_server_squid
Daftar isi
Proxy Server Squid Transparent
Proxy server squid dapat dibuat agar transparan, artinya PC client akan diarahkan/redirect untuk selalu memakai proxy server. PC client tidak perlu lagi melakukan seting proxy di browser.
Pasang Squid
# yum install -y squid
Konfigurasi
Konfigurasi default ada di /etc/squid/squid.conf.default. Artikel squid tingkat lanjutan ini akan menunjukkan cara membuat konfigurasi lebih ringkas, caranya dengan membuang semua baris komentar. Baris komentar dibuang dengan memakai perintah grep, sed dan pipe (tanda lebih besar).
Perintah untuk membuang baris komentar
# grep -v "^#" /etc/squid/squid.conf.default | sed -e '/^$/d' > /etc/squid/squid.conf
Konfigurasi /etc/squid/squid.conf yang sudah ringkas sebagai berikut:
# cat /etc/squid/squid.conf
acl manager proto cache_object acl localhost src 127.0.0.1/32 acl localhost src ::1/128 acl to_localhost dst 127.0.0.0/8 0.0.0.0/32 acl to_localhost dst ::1/128 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 http_access allow manager localhost http_access deny manager http_access deny !Safe_ports http_access deny CONNECT !SSL_ports http_access allow localnet http_access allow localhost http_access deny all http_port 3128 hierarchy_stoplist cgi-bin ? coredump_dir /var/spool/squid 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 bash-4.1#
Buat cache
# /usr/sbin/squid -z
Jalankan squid
# service squid start
Masukkan service squid
# chkconfig --level 345 squid on
Konfigurasi browser di komputer klien
TIDAK PERLU mengubah konfigurasi browser agar memakai proxy server!
Periksa log
# tail -f /var/logs/squid/access.log
Jalankan browser dari komputer klien lalu akses situs. Di server perhatikan log yang muncul, tekan Ctrl + C jika sudah selesai melihat akses.log.
# tail -f /var/logs/squid/cache.log
Jalankan browser dari komputer klien lalu akses situs. Di server perhatikan log yang muncul, tekan Ctrl + C jika sudah selesai melihat cache.log.
