虛拟機centos系統，停機裝第二塊網卡，需要更改的配置

虛拟機centos系統，停機裝第二塊網卡，需要更改的配置。

問題描述： 虛拟機centos系統，停機裝第二塊網卡，發現  /etc/sysconfig/network-scripts/ifcfg-eth1 不存在。但 ifconfig 能夠看到  eth1  中的  HWaddr  值。

[root@11gnode1 ~]# ifconfig

eth0 Link encap:Ethernet HWaddr 00:0C:29:06:C9:21 

inet addr:10.100.25.8 Bcast:10.255.255.255 Mask:255.0.0.0

[root@11gnode1 ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth1

[root@11gnode1 ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth1

cat: /etc/sysconfig/network-scripts/ifcfg-eth1: No such file or directory

解決辦法： 經過實踐，虛拟機centos系統，停機裝第二塊網卡，需要人工手動建立 eth1 檔案。

1. 建立 eth1 檔案，并根據  ifconfig 結果中的  HWADDR 值編輯檔案。

[root@11gnode1 ~]# touch /etc/sysconfig/network-scripts/ifcfg-eth1

2. 檢視驗證。
