5、初始化及启动squid
#useradd -s /sbin/nologin squid #创建squid用户
#mkdir -p /usr/local/squid/var/cache #创建缓存目录
#chown -R squid:squid /usr/local/squid/var/cache #授权给squid
#chown -R squid:squid /usr/local/squid/var/logs
#vim /etc/hosts
192.168.0.201 www.gangpao.com #绑定hosts文件指定图片服务器ip
192.168.0.202 shop.gangpao.com
#/usr/local/squid/sbin/squid -zX #初始化缓存目录
#/usr/local/squid/sbin/squid -s #启动squid
#ps aux|grep squid #检查squid是否启动，出现下面进程，表示启动成功！
root 34370.00.6 6240 424 ? Ss 21:42 0:00 /usr/local/squid/sbin/squid -s
squid 34390.09.7240325888 ? S 21:42 0:01 (squid) -s
squid 34400.00.6 2932 420 ? S 21:42 0:00 (unlinkd)
root 39220.01.1 3912 676 pts/0 S+ 22:40 0:00 grep squid
6、测试
在客户端绑定hosts域名指向squid服务器
#vim /etc/hosts
192.168.0.200 www.gangpao.com
192.168.0.200 shop.gangpao.com
#curl -I http://www.gangpao.com/6.jpg
