大型门户网站、门户论坛服务器。大型购物网站服务器。
做好一个网站之后,有两种选择,一是租赁或者购买服务器,然后托管到电信机房,至于需要几台服务器,这个要看你网站的流量有多大,如果刚刚起步,一天只有几万的IP,一台足矣。但是这样成本相对比较高,买服务器、架设服务器、托管费用、后期服务器的管理、运行的安全问题,都是要考虑到的。不然三天两天被人攻击,是很烦的。比如说你卖了几天的商品,突然被攻击,网站无法访问,是相当晕人的。。。二是可以购买云主机,成本低廉,相对配置比较低,运作起来跟独立服务器一样的。问题二:其他都不需要了建议:如果是网站要求比较低,推荐云主机,省资金。如果业务发展到云主机已经不能承载的时候,建议用高配的独立服务器。常见的网站攻击有两种:
1,流量攻击,就是我们常说的DDOS和DOS等攻击,这种攻击属于最常见的流量攻击中的带宽攻击,一般是使用大量数据包淹没一个或多个路由器、服务器和防火墙,使你的网站处于瘫痪状态无法正常打开。但是这种攻击成本都会很高,所以遇到这样的攻击的时候大家不要惊慌,另外可以试试防御系统,这样的话攻击不会主要针对你的网站。
2, CC攻击,也是流量攻击的一种,CC就是模拟多个用户(多少线程就是多少用户)不停地进行访问那些需要大量数据操作(就是需要大量CPU时间)的页面,造成服务器资源的浪费,CPU长时间处于100%,永远都有处理不完的连接直至就网络拥塞,正常的访问被中止。
防御手段:
遇到流量攻击的话,防御只能靠硬防。硬防就是硬件防火墙,表面看上去跟普通的服务器差不多,顾名思义就是硬件组成的防火墙。主要用来扛流量攻击。硬防的话。10G墙都要十几万。成本高,需要一定的出口带宽支持。所以一般都是一些大的高防机房架设起来。
网站一般都会被打CC攻击。打封端口。无效请求,占用机器带宽。内存占用率升高,会使得服务器延时,甚至宕机。有效防御常见有加带宽,装软防,调策略。专业的技术,根据攻击调整防护墙上的策略,屏蔽无限防的请求IP。能有效的减缓CC攻击。
其解决方案是:使用高防服务器。同时高效防御两种攻击。
