Fuel部署Openstack遇到node untitled discovered dhcp server via eth0 with follo...

验证网络连通性出错

错误信息

将本地fule master节点上载到服务器上后，在fuel web界面上验证网络连通性时报错：
node untitled discovered dhcp server via eth0 with following parameters ip

解决方案

可以看到错误分为两块：
- 10.20.0.2与安装过程冲突
- 192.168.0.1与安装过程冲突
其中10.20.0.2是fuel master的IP，192.168.0.1是服务器网关路由的IP。
第一块错误的原因是：从本地上载master节点到服务器上，导致节点网卡的mac地址不一致。先来解决这一个错。

Fuel master节点MAC地址问题

本地的master节点四块网卡MAC地址为：

"00:0C:29:AA:51:61"
"00:0C:29:AA:51:6B"
"00:0C:29:AA:51:75"
"00:0C:29:AA:51:7F"

因此咱们需要修改服务器master四块网卡的MAC地址，修改步骤如下：

• 修改master节点对应的vmx文件：
  

修改前：

[mw_shl_code=bash,true]ethernet0.virtualDev = "e1000"
ethernet0.networkName = "network_lw_3"
ethernet0.addressType = "static"
ethernet0.present = "TRUE"
ethernet1.virtualDev = "e1000"
ethernet1.networkName = "network_lw_3"
ethernet1.addressType = "static"
ethernet1.present = "TRUE"
ethernet2.virtualDev = "e1000"
ethernet2.networkName = "network_lw_3"
ethernet2.addressType = "static"
ethernet2.present = "TRUE"
ethernet3.virtualDev = "e1000"
ethernet3.networkName = "network_lw_3"
ethernet3.addressType = "static"

uuid.bios = "42 15 69 82 80 27 f6 52-da 5c bb dd e4 b0 0d 1b"

ethernet0.address = "00:50:56:34:41:0F"
ethernet1.address = "00:0C:29:AA:51:6B"
ethernet2.address = "00:0C:29:AA:51:75"
ethernet3.address = "00:0C:29:AA:51:7F"[/mw_shl_code]

将网卡addressType设置为“generated”：
[mw_shl_code=bash,true]ethernet0.virtualDev = "e1000"
ethernet0.networkName = "network_lw_3"
ethernet0.addressType = "generated"
ethernet0.present = "TRUE"
ethernet1.virtualDev = "e1000"
ethernet1.networkName = "network_lw_3"
ethernet1.addressType = "generated"
ethernet1.present = "TRUE"
ethernet2.virtualDev = "e1000"
ethernet2.networkName = "network_lw_3"
ethernet2.addressType = "generated"
ethernet2.present = "TRUE"
ethernet3.virtualDev = "e1000"
ethernet3.networkName = "network_lw_3"
ethernet3.addressType = "generated"[/mw_shl_code]


VMware MAC地址的生成是根据uuid.bios生成的，并且始终保证uuid.bios的后三项即为第一块网卡的MAC地址的后三位，因此，我们需要将bios这一项需要将最后三个数字改为AA:51:61，再修改网卡MAC地址：

[mw_shl_code=bash,true]uuid.bios = "42 15 69 82 80 27 f6 52-da 5c bb dd e4 aa 51 61"

ethernet0.address = "00:0C:29:AA:51:61"
ethernet1.address = "00:0C:29:AA:51:6B"
ethernet2.address = "00:0C:29:AA:51:75"
ethernet3.address = "00:0C:29:AA:51:7F"[/mw_shl_code]

• 修改虚拟机设置中四张网卡的mac为上述配置中对应的地址：
  如第一张网卡：
  

• 修改vsphere，允许该端口组的MAC“地址更改”与“伪传输”
  

再验证网络，结果如下图，可以看到只有10.20.0.2的错误已经解决

网关问题

网络连通性报错的是192.168.0.1与安装过程冲突，注意我们在本地利用Fuel安装Openstack时，配置网络时，特意去掉了DHCP：





所以我们将192.168.0.1路由的DHCP功能关闭吧先….
关闭之后再重新验证，验证成功~
