今天拿到客户两笼刀片机，进行RHEL6U3系统的安装操作，打算安装完第一台刀片之后，将其配置成KICKSTART服务器对其他刀片进行网络安装。

然而，安装完第一片刀之后，对其进行IP的设置。

1. 首先查看有多少个网卡

[root@blog01 ~]# ip a1: lo: 
    
      mtu 16436 qdisc noqueue state UNKNOWN    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00    inet 127.0.0.1/8 scope host lo    inet6 ::1/128 scope host       valid_lft forever preferred_lft forever2: eth0: 
     
       mtu 1500 qdisc mq state UP qlen 1000    link/ether 38:ea:a7:a1:fd:66 brd ff:ff:ff:ff:ff:ff    inet6 fe80::3aea:a7ff:fea1:fd66/64 scope link       valid_lft forever preferred_lft forever3: eth1: 
      
        mtu 1500 qdisc noop state DOWN qlen 1000    link/ether 38:ea:a7:a1:fd:6a brd ff:ff:ff:ff:ff:ff4: eth2: 
       
         mtu 1500 qdisc noop state DOWN qlen 1000    link/ether 38:ea:a7:a1:fd:68 brd ff:ff:ff:ff:ff:ff5: eth3: 
        
          mtu 1500 qdisc noop state DOWN qlen 1000    link/ether 38:ea:a7:a1:fd:6c brd ff:ff:ff:ff:ff:ff6: eth4: 
         
           mtu 1500 qdisc noop state DOWN qlen 1000 link/ether 38:ea:a7:a1:fd:69 brd ff:ff:ff:ff:ff:ff7: eth5: 
          
            mtu 1500 qdisc noop state DOWN qlen 1000 link/ether 38:ea:a7:a1:fd:6d brd ff:ff:ff:ff:ff:ff8: eth6: 
           
             mtu 1500 qdisc noop state DOWN qlen 1000 link/ether 38:ea:a7:a1:fd:6e brd ff:ff:ff:ff:ff:ff9: eth7: 
            
              mtu 1500 qdisc noop state DOWN qlen 1000 link/ether 38:ea:a7:a1:fd:72 brd ff:ff:ff:ff:ff:ff
            
           
          
         
        
       
      
     
    

[root@blog01 ~]# for i  in `seq 0 7`> do> res=`ethtool eth$i |grep Link |awk -F: '{print $2}'`> echo "eth$i  Link $res"> doneeth0  Link  yeseth1  Link  yeseth2  Link  noeth3  Link  noeth4  Link  noeth5  Link  noeth6  Link  noeth7  Link  no

3. 可以看出eth0,eth1是连接成功的

4. 对eth0配置IP地址

从客户获得的IP设置范围是10.196.28.0/24 ,该网段端口被设置成了Trunk模式。

5.手动将eth0加入vlan id为528的VLAN，并配置IP

[root@blog01 ~]# vconfig  add eth0 528[root@blog01 ~]# ifconfig eth0.528 10.196.28.43 netmask 255.255.255.0[root@blog01 ~]# ping  -W1 -c2 10.196.28.254PING 10.196.28.254 (10.196.28.254) 56(84) bytes of data.64 bytes from 10.196.28.254: icmp_seq=1 ttl=255 time=1.14 ms64 bytes from 10.196.28.254: icmp_seq=2 ttl=255 time=1.15 ms--- 10.196.28.254 ping statistics ---2 packets transmitted, 2 received, 0% packet loss, time 1002msrtt min/avg/max/mdev = 1.149/1.154/1.159/0.005 ms

6.写入网卡配置文件

为了使得系统重启后，IP配置仍旧生效，写入系统配置文件

另外本机需要作为KVM虚拟化平台，故需要创建桥接设备br0

[root@blog01 ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0DEVICE=eth0ONBOOT=yesTYPE=EthernetBOOTPROTO=none[root@blog01 ~]#cat /etc/sysconfig/network-scripts/ifcfg-eth0.528DEVICE=eth0.528ONBOOT=yesBOOTPROTO=noneVLAN=yesTYPE=EthernetBRIDGE=br0[root@blog01 ~]#cat /etc/sysconfig/network-scripts/ifcfg-br0DEVICE=br0ONBOOT=yesBOOTPROTO=noneTYPE=BridgeIPADDR=10.196.28.43NETMASK=255.255.255.0GATEWAY=10.196.28.254

7.重新启动网络服务，查看最终网卡配置信息

[root@blog01 ~ ]# service network restart[root@blog01  ~]# cat /proc/net/vlan/configVLAN Dev name     | VLAN IDName-Type: VLAN_NAME_TYPE_RAW_PLUS_VID_NO_PADeth0.528       | 528  | eth0[root@SJC42KVM01 ~]# brctl  showbridge name    bridge id        STP enabled    interfacesbr0        8000.38eaa7a1fd66    no        eth0.528[root@SJC42KVM01 ~]# ifconfig  eth0eth0      Link encap:Ethernet  HWaddr 38:EA:A7:A1:FD:66           inet6 addr: fe80::3aea:a7ff:fea1:fd66/64 Scope:Link          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1          RX packets:14600981 errors:0 dropped:0 overruns:0 frame:0          TX packets:16880 errors:0 dropped:0 overruns:0 carrier:0          collisions:0 txqueuelen:1000          RX bytes:1175506152 (1.0 GiB)  TX bytes:4080056 (3.8 MiB)[root@blog01  ~]# ifconfig  eth0.528eth0.528  Link encap:Ethernet  HWaddr 38:EA:A7:A1:FD:66           inet6 addr: fe80::3aea:a7ff:fea1:fd66/64 Scope:Link          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1          RX packets:600 errors:0 dropped:0 overruns:0 frame:0          TX packets:313 errors:0 dropped:0 overruns:0 carrier:0          collisions:0 txqueuelen:0          RX bytes:66715 (65.1 KiB)  TX bytes:57925 (56.5 KiB)[root@blog01 ~]# ifconfig  br0br0       Link encap:Ethernet  HWaddr 38:EA:A7:A1:FD:66           inet addr:10.196.28.43  Bcast:10.196.28.255  Mask:255.255.255.0          inet6 addr: fe80::3aea:a7ff:fea1:fd66/64 Scope:Link          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1          RX packets:549 errors:0 dropped:0 overruns:0 frame:0          TX packets:345 errors:0 dropped:0 overruns:0 carrier:0          collisions:0 txqueuelen:0          RX bytes:63581 (62.0 KiB)  TX bytes:64296 (62.7 KiB)

8.测试网络连接是否通畅

[root@blog01 ~]# ping -W1 -c2  10.196.28.254PING 10.196.28.254 (10.196.28.254) 56(84) bytes of data.64 bytes from 10.196.28.254: icmp_seq=1 ttl=255 time=1.31 ms64 bytes from 10.196.28.254: icmp_seq=2 ttl=255 time=0.907 ms--- 10.196.28.254 ping statistics ---2 packets transmitted, 2 received, 0% packet loss, time 1002msrtt min/avg/max/mdev = 0.907/1.108/1.310/0.204 ms[root@blog01 ~]# ping -W1 -c2  10.192.28.254PING 10.192.28.254 (10.192.28.254) 56(84) bytes of data.64 bytes from 10.192.28.254: icmp_seq=1 ttl=249 time=2.63 ms64 bytes from 10.192.28.254: icmp_seq=2 ttl=249 time=2.78 ms--- 10.192.28.254 ping statistics ---2 packets transmitted, 2 received, 0% packet loss, time 1004msrtt min/avg/max/mdev = 2.635/2.709/2.784/0.090 ms

配置完成！
