squid guidance
 

I need some help regarding to squid proxy server. well if you view the following web site
http://pbraun.nethence.com/doc/www/squid.html
you can see the all settings which need for squid as a cache server.I want to know some few things about it in
Prepare the system,
mv /var/spool/squid /var/spool/squid.dist
mkdir /cache
chown squid:squid /cache
chmod 750 /cache
why the user use the mv command ?

and in the following

Prepare the file,
mv /etc/squid/squid.conf /etc/squid/squid.conf.dist
sed '/^#/d;/^$/d' /etc/squid/squid.conf.dist > /etc/squid/squid.conf
chown root:squid squid.conf
chmod 640 squid.conf

again the user use the mv coomand to move the file.why he use sed command ?About chown command is the user assigning rights of squid files to the root ?
and last think i want to know that what does squid -z do ?
kindly guide me ,
should be grateful to you
garden.

Here mv command is used to rename the file squid.conf to squid.conf.dist , so the original file is saved. Now sed is used to remove the # mark and the blank spaces from the squid.conf.dist and save the output in squid.conf.

So the original files will be deleted
It will remove the lines containing #
It will chown to user root and group squid
It will create the swap directories


Kind regards

thanks for the reply . well what about

chown squid:squid /cache
chmod 750 /cache

and

squid -z

kindly guide me this as well
thanks.

user squid and group squid

It will create the swap directories

Kind regards

thanks a lot for your guidance.well there is a little confusion about cache directory.mkdir /cache which will create directory and squid -z swap dir.so why need to create dir two times?technically what is the difference between cache and swap dir in sauid?

2- my phycal ram is 4 GB so what should i keep the cache dir size in squid.conf file.
Thaks again for guiding me.

You don't need to use them both
will create what you want with the proper permissions.

the cache dir will not run in RAM
