CentOS6裏面ifcfg-eth0對於大小寫敏感

裝了一臺CentOS，在設置以太網網絡參數的時候

cd /etc/sysconfig/network-scripts

裏面有個ifcfg-eth0文件，vi編輯它

一開始的時候默認內容是

DEVICE="eth0"
HWADDR="CE:CB:F3:34:24:A0"
NM_CONTROLLED="yes"
ONBOOT="no"

我現在根據我的網絡環境，設置爲

DEVICE="eth0"
HWADDR="CE:CB:F3:34:24:A0"
NM_CONTROLLED="yes"
ONBOOT="yes"
ipaddr="172.18.11.2"
network="255.255.0.0"
gateway="172.18.11.1"

保存退出，service network restart重啓網絡服務，期待設置的網絡參數生效

沒想到無效

[root@localhost network-scripts]# service network restart
Shutting down interface eth0:  [  OK  ]
Shutting down loopback interface:  [  OK  ]
Bringing up loopback interface:  [  OK  ]
Bringing up interface eth0:  [  OK  ]

[root@localhost network-scripts]# ifconfig
eth0      Link encap:Ethernet  HWaddr CE:CB:F3:34:24:A0 
          inet6 addr: fe80::cccb:f3ff:fe34:24a0/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:788 errors:0 dropped:0 overruns:0 frame:0
          TX packets:29 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:283534 (276.8 KiB)  TX bytes:2020 (1.9 KiB)
          Interrupt:9

裏面沒有ip地址的內容

回頭在看看剛纔ifcfg-eth0，把裏面的最後三行改成大寫字母

DEVICE="eth0"
HWADDR="CE:CB:F3:34:24:A0"
NM_CONTROLLED="yes"
ONBOOT="yes"
IPADDR="172.18.11.2"
NETMASK="255.255.0.0"
GATEWAY="172.18.11.1"

保存退出，再次service network restart

再來驗證一下是否生效

[root@localhost network-scripts]# ifconfig
eth0      Link encap:Ethernet  HWaddr CE:CB:F3:34:24:A0 
          inet addr:172.18.11.2  Bcast:172.18.255.255  Mask:255.255.0.0
          inet6 addr: fe80::cccb:f3ff:fe34:24a0/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:870 errors:0 dropped:0 overruns:0 frame:0
          TX packets:51 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:288490 (281.7 KiB)  TX bytes:3494 (3.4 KiB)
          Interrupt:9

 

OK了，看來大小寫敏感啊
