squid做内部图片缓存

如果公司网站的图片非常多，公司内部又使用了内部DNS的话，为了加快游览公司网站，你可以在内部搭建台SQUID服务器，以加快速度。

 

------------安装--------------
cd /usr/local/src
tar zxvf squid-2.5.STABLE12.tar.gz
cd squid-2.5.STABLE12
./configure --prefix=/usr/local/squid --disable-internal-dns
make all
make install
chmod -R 777 /usr/local/squid
cd /usr/local/squid/etc/
mv squid.conf squid.conf.source

 

vi /usr/local/squid/etc/squid.conf

把你公司的网站图片服务器地址与对应的域名全部添加到hosts文件中

如：echo "x.x.x.x x.x.com" >> /etc/hosts

 

mkdir /cache

chmod -R 777 /cache

 

echo "/usr/local/squid/sbin/squid -z " >> /etc/rc.local

echo "/usr/local/squid/sbin/squid -D " >> /etc/rc.local

 

echo "# reboot Squid cache" >>/root/restart_squid.sh
echo "killall -9 squid" >>/root/restart_squid.sh
echo "rm -rf /cache/* " >>/root/restart_squid.sh
echo "rm -f /usr/local/squid/var/logs/squid.pid " >>/root/restart_squid.sh
echo "/usr/local/squid/sbin/squid -z " >>/root/restart_squid.sh
echo "/usr/local/squid/sbin/squid -D " >>/root/restart_squid.sh
echo "# /usr/local/squid/sbin/squid -k reconfigure " >>/root/restart_squid.sh

 

chmod 777 -R /root/restart_squid.sh （可执行文件，方便以后使用）

 

crontab -l
30 4 * * * /root/restart_squid.sh

 

service iptables stop（关闭防火墙）

iptables -L（查看防火墙是否开启）

 

du -sh /cache查看cache （里面容量数值有变化，说明SQUID运作正常）
/usr/local/squid/sbin/squid -k reconfigure 刷新
