On a redhat distro, this is what I have done, for 2 squid instances... This is only in the lab so I may have missed something, hope it helps a little.... Make a /etc/squid2 directory & copy data into it, also make a cache dir for the second instance & copy the init script mkdir /etc/squid2 cp -r /etc/squid /etc/squid2 cp /etc/init.d/squid /etc/init.d/squid2 mkdir -p /var/spool/squid2 ; chmod 750 /var/spool/squid2 ; chown squid.squid /var/spool/squid2 Link squid2 to squid ( to get a different process to look for in the initscripts pidof() ) ln -s /usr/sbin/squid /usr/sbin/squid2 Differences between /etc/init.d/squid & /etc/init.d/squid2 ( < = squid > = squid2 ) < [ -f /etc/squid/squid.conf ] || exit 0 > [ -f /etc/squid2/squid.conf ] || exit 0 < if [ -f /etc/sysconfig/squid ]; then < . /etc/sysconfig/squid > if [ -f /etc/sysconfig/squid2 ]; then > . /etc/sysconfig/squid2 < [ -f /usr/sbin/squid ] && SQUID=squid > [ -f /usr/sbin/squid2 ] && SQUID=squid2 < CACHE_SWAP=`sed -e 's/#.*//g' /etc/squid/squid.conf | \ > CACHE_SWAP=`sed -e 's/#.*//g' /etc/squid2/squid.conf | \ < [ -z "$CACHE_SWAP" ] && CACHE_SWAP=/var/spool/squid > [ -z "$CACHE_SWAP" ] && CACHE_SWAP=/var/spool/squid2 < $SQUID -z -F -D 2>/dev/null > $SQUID -f /etc/squid2/squid.conf -z -F -D 2>/dev/null < [ ! -f /var/run/squid.pid ] || break > [ ! -f /var/run/squid2.pid ] || break < $SQUID -k shutdown & > $SQUID -f /etc/squid2/squid.conf -k shutdown & < [ -f /var/run/squid.pid ] || break > [ -f /var/run/squid2.pid ] || break < [ -e /var/lock/subsys/squid ] && restart || : > [ -e /var/lock/subsys/squid2 ] && restart || : Differences between /etc/squid/squid.conf & /etc/squid2/squid.conf ( < is squid/squid.conf > is squid2/squid.conf ) < cache_dir aufs /var/spool/squid 5000 32 256 > cache_dir aufs /var/spool/squid2 5000 32 256 > cache_access_log /var/log/squid2/access.log > cache_log /var/log/squid2/cache.log > pid_filename /var/run/squid2.pid chkconfig squid2 on service squid2 start Hope this helps as well...
