RE: [squid-users] 2 squid processes

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 /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...

"squid -f /path/to/second/squid.conf -z" ought to do it.
