How to Clear Cache on Squid 3 - Debian 6.0

There are 4 steps in clearing the cache of squid3.

1. Stop squid3.

$/etc/init.d/squid3 stop

2. Delete the cache directory.

$rm -Rf /var/spool/squid3/*

3. Create swap Directories.

$squid3 -z

4. Start squid3.

/etc/init.d/squid3 start

To make it easier, you can just do it in one shot.

Here's a script that I made to do that.

**********************************************

#!/bin/sh

#clear cache squid3 by lui 06-01-2011

/etc/init.d/squid3 stop;

sleep 1;

rm -Rf /var/spool/squid3/*;

sleep 1;

squid3 -z;

sleep 1;

/etc/init.d/squid3 start;

**********************************************

After clearing the cache, you can verify it by using "squidclient" to check squid cache storage.

1. Install squidclient.

$apt-get install squidclient

2. Check the cache storage capacity.

$squidclient mgr:storedir

Look for this line:

Current Capacity: 0% used, 100% free
