VPS被删除后,里面的数据还能恢复吗?

Posted by zuzhihui in 常见问题 on 2011/01/29 with No Comments

我的VPS由于欠费被自动删除了,VPS里面的数据还能恢复吗?答案是不一定。

如果VPS刚被删除,恢复的可能性比较大,如果被删除了很多天了,恢复的可能性就很小了。

如果您的VPS由于欠费7天被删除了,然后想把数据恢复回来,需要补齐VPS的费用,另外补交50元数据恢复服务费。

关于VPS被攻击

Posted by zuzhihui in 最新消息 on 2011/01/28 with No Comments

做网站有可能会被攻击,虽然这个可能性很小,但还是存在的。无论是VPS,虚拟主机还是独立服务器,都有可能会被攻击。

VPS等网站被攻击的原因,基本上都和网站内容有关系,比如私服,赌博之类的网站被攻击的可能性就比较大。而一般的网站,是极少被攻击的。

对于一般的攻击,我们机房可以抵挡。对于比较大型的DDOS攻击,机房无法抵挡,机房只能把被攻击的IP给封掉。大型的DDOS会发起非常大的流量涌向机房,把机房的整个入口给淹没掉,这时会导致机房里所有的VPS都无法和外界通信。这时候如果仅仅停掉被攻击的VPS或者服务器,是没法化解机房入口拥堵的流量的,必须把被攻击的IP从路由器上做空,这样相当于对外界广播:“此IP现在已经不在我们机房”,这样攻击的流量就不会被路由到机房的入口,机房就恢复正常了。

为了给各位vps客户提供更加稳定的网络,必须要杜绝或者最大限度减少被大型DDOS攻击的可能性。所以机房决定,如果被大型DDOS攻击,将封IP至少24小时,24小时后客户申请解封IP。给机房其他客户造成损失的,罚款150元。请大家理解。

什么是VPS主机(虚拟私有服务器)

Posted by zuzhihui in 常见问题 on 2011/01/28 with No Comments

VPS的全称是Virtual Private Server,中文就是”虚拟私有服务器”。VPS还有另外一个名称是VDS(Virtual Dedicated Server,虚拟专用服务器)。把一个物理服务器分成多个虚拟服务器使用,每个虚拟服务器上安装完整的操作系统,配置单独的IP地址,各个虚拟服务器互不影响,可以单独重启。这样的虚拟服务器就是VPS。在VPS上的操作系统看来就好象运行在一个独立的物理主机上。

这种把一个物理服务器分成多个VPS使用的技术就叫做虚拟化技术,当前有各种不同的虚拟化技术。我们瑞豪开源使用的虚拟化技术叫做XEN,这是英国剑桥大学研发的一种虚拟化技术。XEN虚拟化技术的性能被公认为是最好的,详见这个报告。

VPS和网站空间的区别很大,这两个根本不是一类概念。VPS是个完整的操作系统,而网站空间仅仅是网站空间。可以在VPS上安装软件划分出很多空间,绑定很多域名。可以在VPS上安装运行任何程序,包括网站程序,数据库程序,VPN程序,代理程序等等,而网站空间的作用仅仅是存放网页。

什么是空域名CNAME?

Posted by zuzhihui in 域名 on 2011/01/19 with 2 Comments

这里说的空域名是指前缀为空的域名记录,比如live.com是空域名,而www.live.com和mail.live.com等就不是空域名。

一个域名记录可以指向一个IP地址,指向一个IP地址的域名记录叫做A记录,指向另外一个别名域名的记录叫做CNAME记录,A记录是指向IP地址的,CNAME是别名记录,是用来指向其他域名的。CNAME别名记录的好处是当IP变化的时候,不用修改此CNAME记录,只要修改CNAME所指向的域名的解析即可。

一般的DNS服务器是不支持空域名CNAME记录的,包括瑞豪开源的默认DNS服务器也不支持。支持空域名CNAME的DNS服务器列举几个如下:

使用he.net的免费DNS服务器

Posted by zuzhihui in 客户服务 on 2011/01/18 with No Comments

he.net提供免费的DNS服务器。he.net是美国老牌IDC,在技术领域比较强,尤其是IPV6应用。he.net提供的DNS服务器都在美国,如果网站的访问者大部分在国外,建议he.net的DNS服务器,会比国内的DNS服务器快一些。如果用国内的DNS,那么Google的爬虫在抓取网站的时候可能会碰到DNS错误,而使用he.net的DNS服务器则不会有这个问题。另外,he.net的DNS服务器还支持空域名CNAME 。

使用he.net的DNS服务器的步骤如下:

注册

在首页 https://dns.he.net/ 点击Register!按钮,然后会进入 http://ipv6.he.net/certification/register.php 注册新用户。注意注册信息要填写完整,email地址一定要准确,注册后密码会发到邮箱里面去。

使用

注册成功后,密码会发到注册的邮箱里面去。

在浏览器里面输入dns.he.net后,输入用户名密码登录进去。然后重新在浏览器地址栏里面输入dns.he.net,主界面左侧会有“Add a new domain”,点击”Add a new domain”可以新增一个域名,在域名列表点击小图标可以管理这个域名的DNS解析。新增加一个域名后,要到域名服务商那里把该域名的DNS服务器修改为dns.he.net提供的DNS服务器,dns.he.net提供了5个DNS服务器如下,一般修改为前两个即可。
ns1.he.net
ns2.he.net
ns3.he.net
ns4.he.net
ns5.he.net

在域名服务商那里修改后,等几分钟就应该会生效了。

解析

在dns.he.net,登录后,进入要解析的域名,点击New A按钮可以添加一个A记录。一般至少添加两个A记录,一个是www,一个是空的。

反投诉IP更换

Posted by zuzhihui in 客户服务 on 2011/01/18 with No Comments

反投诉部署文档 怎样给一个网站使用反投诉解决方案  和 外贸网站反投诉解决方案  里面提到的老的反投诉IP是202.142.24.139,现在已经更换为:202.142.20.138。请各个部署了反投诉的客户,用这个新IP 202.142.20.138替换老IP 202.142.24.139。假如您的反投诉的域名是good.com,那就解析good.com的A记录到202.142.20.138。

为什么换IP?因为老IP 202.142.24.139现在被反垃圾邮件组织列为垃圾IP,而新IP 202.142.20.138 是干净的。

不换IP有什么问题吗?如果您坚持使用老IP,那么您的域名可能会被受到牵连。

以后如果再换反投诉IP,做了反投诉的域名可以不做修改吗?可以的,我们正在酝酿这个解决方案,预计3天之后就可以实现。

点击别人的域名为什么会进入我vps上的网站?

Posted by zuzhihui in Linux技术 on 2011/01/17 with No Comments

点击别人的域名bad.com为什么会进入我vps上的网站good.com?

这是因为别人的域名bad.com指向了您的VPS的IP地址,访问bad.com就访问到您的ip上面了。别人的域名指向您的IP,这个事情咱们拿他没办法,他的域名bad.com爱指向哪个ip,我们无法干涉。

但是,bad.com指向我们的ip,我们可以想办法让他无法访问。在VPS上创建一个网站,就叫bad.com,然后做一个网站首页,首页写上:”这是一个骗子网站”。这样如果bad.com域名指向过来,访问的时候就会看到这个首页,而不是自己的其他网站。

如果您的vps使用的是apache,也可以通过修改您网站的.htaccess文件来把其它域名重定向到其他网站比如google.com去,.htaccess中做如下修改即可:

RewriteCond %{HTTP_HOST} !^www\.good\.com [NC]
RewriteCond %{HTTP_HOST} !^good\.com [NC] 
RewriteRule (.*) http://www.google.com [L,R=301]

如果是Kloxo控制面板,请参考 lighttpd环境下在kloxo中把网站301重定向到另外一个网站

另外,grep smartd /var/log/message* 可以看到很多smartd报告的错误信息:

在国内注册域名要慎重

Posted by zuzhihui in 域名 on 2011/01/14 with No Comments

在国内注册域名慎重,因为国内的域名注册商经常会随便停止一个域名的解析,给客户造成很大的损失。瑞豪开源有几个客户在国内注册的域名,由于国外厂家向域名注册商投诉侵权,这些国内域名注册商一收到投诉,就不问青红皂白把域名停止解析了。

瑞豪开源提供域名注册服务,不会随便暂停域名。欢迎各位在瑞豪开源注册域名,转入域名到瑞豪开源,转入域名的流程是 怎样把域名转移到RASHOST
