How to clear squid log manually in centOS/RHEL

In this post i am going to delete/clear squid log manually.

Method:1 - Fast way to delete squid log (later you can delete directory squid.old )

#cd /var/spool/
#mv squid squid.old
#mkdir squid
#chown squid.squid squid
#ls -ld squid
drwxr-xr-x 18 squid squid 4096 Feb  5 03:06 /var/spool/squid

Restart service, after restarting server cache directory create automatically
#service squid restart

Verify that user are accecing internet or not 
# tail -f /var/log/squid/access.log

#service squid restart

# ls

Method:3- Using script

Create a file name as squidclear.sh

#cat squidclear.sh

# cat squidlogclear.sh

#/bin/bash

rm -rf /var/spool/squid/*

rm -rf /var/log/squid/*.gz

echo >/var/log/squid/access.log

echo >/var/log/squid/cache.log

echo >/var/log/squid/squid.out

echo >/var/log/squid/store.log

squid -z

service squid restart

Make script executable

#chmod o+x squidclear.sh

Run scrip

# ./squidclear.sh
