操作系统下都有hosts文件可自定单个域名指向IP，要将特定域名下所有子域名都指向特定IP就需要转发DNS服务器来解决了，Dnsmasq就是比较轻量级的一个，很多第三方路由固件都自带Dnsmasq。
Dnsmasq域名泛解析配置：

address=/.www.haiyun.me/8.8.8.8
address=/.google.com/203.208.46.200
#这样所有www.haiyun.me子域名都解析到8.8.8.8

Dnsmasq禁止域名被劫持：

bogus-nxdomain=8.8.8.8
#8.8.8.8为劫持IP地址

LVM分区在查看PV时提示以下错误：

pvscan 
  Couldn't find device with uuid MBRrbL-wujm-Tfpe-h2qo-M6vo-9W1B-Im0zjo.
  PV /dev/xvda2       VG VolGroup00      lvm2 [7.88 GB / 0    free]
  PV /dev/xvda3       VG VolGroup00      lvm2 [1.97 GB / 0    free]
  PV unknown device   VG VolGroup00      lvm2 [9.97 GB / 9.97 GB free]

VG中去除PV unknown device：

vgreduce --removemissing /dev/VolGroup00 #去除未知或已丢失的VG
  Couldn't find device with uuid MBRrbL-wujm-Tfpe-h2qo-M6vo-9W1B-Im0zjo.
  Wrote out consistent volume group VolGroup00

从VG中去除特定PV：

vgreduce VolGroup00  /dev/xvdb1

删除PV：

pvremove  /dev/xvdb1

Kloxo面板重启Apache时提示以下错误：

[Tue Dec 18 22:07:51 2012] [warn] NameVirtualHost 8.8.8.8:80 has no VirtualHosts
[Tue Dec 18 22:07:51 2012] [warn] NameVirtualHost 8.8.8.8:443 has no VirtualHosts

原因是在以下配置文件内重复设置NameVirtualHost，注释一个即可。

/etc/httpd/conf/kloxo/init.conf
/etc/httpd/conf/kloxo/virtualhost.conf
