sebaiknya buat dahulu direktori cache pada waktu instalasi

SETTING PROXY OpenBSD
Extract squid
# mkdir /usr/local/src
# tar zxvf squid-2.5.STABLE14.tar.gz -C /usr/local/src

# groupadd squid
# useradd -m -d /cache -g squid -s /dev/null squid

Edit squid
# cd /usr/local/src/squid-2.5.STABLE14
# ee icons/Makefile.in
Ganti dari icondir=$(datadir)/icons
Menjadi icondir=$(libexecdir)/icons

# ee src/Makefile.in
Ganti dari DEFAULT_LOG_PREFIX=$(localstatedir)/logs
Menjadi DEFAULT_LOG_PREFIX=$(localstatedir)/log/squid
Ganti dari DEFAULT_PID_FILE=$(DEFAULT_LOG_PREFIX)/squid.pid
Menjadi DEFAULT_PID_FILE=$(localstatedir)/run/squid.pid
Ganti dari DEFAULT_SWAP_DIR=$(localstatedir)/cache
Menjadi DEFAULT_SWAP_DIR=/cache
Ganti dari DEFAULT_ICON_DIR=$(datadir)/icons
Menjadi DEFAULT_ICON_DIR=$(libexecdir)/icons

Kompilasi Squid
# cd /usr/local/src/squid-2.5.STABLE14
# ./configure –prefix=/usr –exec-prefix=/usr –bindir=/usr/sbin –libexecdir=/usr/lib/squid
–localstatedir=/var –sysconfdir=/etc/squid –enable-pf-transparent –enable-snmp –enable-ssl –enable-removal-policies=heap –enable-default-languages=English
–enable-err-languages=English –enable-delay-pools –enable-cache-digests –enable-poll –disable-ident-lookups –disable-hostname-checks –enable-storeio=diskd,ufs

# make
# make install
# mkdir -p /var/log/squid
# chown squid:squid /var/log/squid
# chmod 750 /var/log/squid
# chmod 750 /cache

Edit /etc/squid/squid.conf

Buat direktori cache
# /usr/sbin/squid -z

Jalankan dengan
# /usr/sbin/squid -D untuk start
# /usr/sbin/squid -k shutdown untuk stop
# /usr/sbin/squid -k reconfigure untuk restart

Cek dengan
# tail -f /var/log/messages

Supaya autorun edit
# ee /etc/rc.local

if [ -x /usr/sbin/squid ]; then
echo -n ’squid’; /usr/sbin/squid -D
fi

# ee /etc/pf.conf
rdr on rl1 proto tcp from any to any port 80 -> 192.168.1.1 port 3128 —> rl1 ke local

#### untuk mendel /cache spt biasa
terus untuk delete log nya di
/var/log/squid/access.log
