squid常用命令:
/usr/local/squid/sbin/squid -z 初始化缓存空间
/usr/local/squid/sbin/squid 启动
/usr/local/squid/sbin/squid -k shutdown 停止
/usr/local/squid/sbin/squid -k reconfigure 重新载入配置文件
/usr/local/squid/sbin/squid -k rotate 轮循日志
#acl all src 0.0.0.0/0.0.0.0 and http_access allow all选项定义了一个访问控制列表。详细情况参见和Squid软件
#携带的文档。这里的访问控制列表允许所有对代理服务的访问,因为这里该代理是加速web服务器。
