How do I know where is the Squid cache in the Linux Filesystem, and recreate it as empty?
The Squid cache stores the pages that are made by the client in order to return more quickly on subsequent requests without having to re-download every time the same page from the internet. It may happen, however, of having to clear the cache is to update it, and because it is full. Let’s see what is the correct procedure to be performed!
We identify first where is the Squid cache with the command:
# cat /etc/squid/squid.conf | grep cache_dir
we will see an output similar:
cache_dir ufs /var/spool/squid 10000 32 256
in this case in the directory: /var/spool/squid
Stop the process of Squid with the command:
# /etc/init.d/squid stop
# systemctl stop squid
eliminate the cache with the command:
# rm -rf /var/spool/squid/*
recreate the cache with the command:
# squid -z
Restart Squid with the command:
# /etc/init.d/squid start
# systemctl start squid
At this point we can see the different Squid log cache_log and access_log to verify proper operation!
