Linode VPS默認情況下是通過DHCP自動獲取IP的，所以在安裝Kloxo完成設置Kloxo的時候會出現no_ip_address的提示，這個時候就需要手動設置上IP，這樣才能添加域名。

如果你設置Kloxo的時候出現no_ip_address的提示你可以按照下面步驟修改：

使用編輯器編輯（如果不會用編輯器，可以使用winscp）：/etc/sysconfig/network-scripts/ifcfg-eth0

# Configuration for eth0
DEVICE=eth0
BOOTPROTO=none

# This line ensures that the interface will be brought up during boot.
ONBOOT=yes

# eth0 - This is the main IP address.
# The address, netmask and gateway are all necessary.
IPADDR=12.34.56.78?? #你的IP地址
NETMASK=255.255.255.0? #子網掩碼
GATEWAY=12.34.56.1 #網關

一般這樣設置好，再執行命令：service network restart 重啟網絡就好了，如果還是不通，重啟試一下。

添加第2個IP，可以創建 /etc/sysconfig/network-scripts/ifcfg-eth0:0
# Configuration for eth0:0
DEVICE=eth0:0
BOOTPROTO=none

# This line ensures that the interface will be brought up during boot.
ONBOOT=yes

# eth0:0
IPADDR=34.56.78.90
NETMASK=255.255.255.0
GATEWAY=12.34.56.1

添加第3個IP，創建 /etc/sysconfig/network-scripts/ifcfg-eth0:1 按上面的內容添加到這個文件中，以此類推。

以上辦法都是在CentOS或者Fedora下添加IP的方法，如果是在Debian/Ubuntu下添加IP的方法(注，當然Kloxo沒有Debian下的版本)：

修改 /etc/network/interfaces

# The loopback interface
auto lo
iface lo inet loopback

# Configuration for eth0 and aliases

# This line ensures that the interface will be brought up during boot.
auto eth0 eth0:0 eth0:1

# eth0 - This is the main IP address that will be used for most outbound connections.
# The address, netmask and gateway are all necessary.
iface eth0 inet static
address 12.34.56.78
netmask 255.255.255.0
gateway 12.34.56.1

# eth0:0
iface eth0:0 inet static
address 34.56.78.90
netmask 255.255.255.0

# eth0:1 - Private IPs have no gateway (they are not publicly routable) so all you need to
# specify is the address and netmask.
iface eth0:1 inet static
address 192.168.133.234
netmask 255.255.128.0

保存，重啟網絡，/etc/init.d/networking restart 即可。
