Step #1: Find Squid cache dir location
Open a terminal and then type:
# grep cache_dir /etc/squid/squid.conf
Sample outputs:
cache_dir ufs /var/spool/squid 100 16 256
Step #2: Restart Squid with an empty cache
Open
a terminal and login as root user. Or use the ssh command to login to
the remote server. Once logged in type the following command to shutdown
squid proxy server:
# squid -k shutdown
Use the following rm command to delete the directory:
# rm -rf /path/to/dir/cache/
# rm -rf /var/spool/squid/
Please note that you need repeat the rm command for each cache_dir
location you wish to empty. Next, use the following mkdir command to
create directory and set permission using chown command:
# mkdir /var/spool/squid
# chown squid:squid /var/spool/squid
A note about SELinux user
If you are using SELinux, type the following command to restestore file(s) default SELinux security contexts:
# restorecon -vr /var/spool/squid
Creating cache_dir
Finally, to re-create the cache directories, enter:
# squid -z

Starting squid proxy server
To start squid type:
# squid
OR
# service squid start
Sample outputs:
Starting squid: [ OK ]
Step #3: Verify Squid is running
Type the following commands:
# netstat -tulpn | grep :3128
# tail -f /var/log/squid/access.log
# tail -f /var/log/squid/cache.log
