/usr/local/squid3/sbin/squid -k interrupt
关闭squid（最高优先级，直接杀死squid进程）
/usr/local/squid3/sbin/squid -k kill
滚动日志文件
/usr/local/squid3/sbin/squid -k rotate
设置每周二凌晨四点30分自动滚动日志
echo "30 4 * * 2 root /usr/local/squid3/sbin/squid -k rotate " >>/etc/crontab
目前应用中的squid.conf文件，由于日志文件增长很快，所以直接输出到/dev/null丢弃掉了
