CentOS 6.2 上的靜態 IPv4 和 IPv6 配置

  • April 14, 2016

我嘗試在 CentOS 6.2 上配置靜態 IPv4 和 IPv6 配置。

以下配置完美執行：

# ifconfig eth0 x.x.x.x/29
# route add defalt gw x.x.x.y

# ip addr add dev eth0 XXXX:C810:3001:D00::3/56
# ip -6 route add default XXXX:C810:3001:D00::1

但是，我想在重新啟動後保留此配置。

所以我做了以下配置：

啟用 IPv6

[root@test network-scripts]# cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=test.net
NETWORKING_IPV6=yes

介面配置

[root@test network-scripts]# cat /etc/sysconfig/network-scripts/ifcfg-eth0 
DEVICE="eth0"
BOOTPROTO="static"
ONBOOT="yes"
HWADDR="2C:C3:AC:A8:C3:3E"
IPADDR=x.x.x.x
GATEWAY=x.x.x.x
NETMASK=255.255.255.248
TYPE=Ethernet
IPV6INIT=yes
IPV6ADDR=XXXX:C810:3001:D00::3/56
IPV6_DEFAULTGW=XXXX:C810:3001:D00::1

DNS1=208.67.222.222
DNS2=208.67.220.220
# Only DNS{1,2} according to /usr/share/doc/initscripts-9.03.27/sysconfig.txt
# DNS3=2620:0:ccc::2
# DNS4=2620:0:ccD::2

重啟網路

[root@test network-scripts]# service network restart

IPv6 配置不起作用…

[root@test network-scripts]# ip addr show
1: lo: <LOOPBACK,UP,LOWER_UP> 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 forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
   link/ether 1c:c1:de:b8:a3:fd brd ff:ff:ff:ff:ff:ff
   inet x.x.x.x/29 brd x.x.x.x scope global eth0
   inet6 fe80::1ec1:deff:feb8:a3fd/64 scope link 
      valid_lft forever preferred_lft forever

解析器的 IPv6 地址甚至不在 resolv.conf 中！

我錯過了配置步驟嗎？

我認為 IPv6 配置將是一種形式..

[root@test network-scripts]# lsb_release -a
LSB Version:    :core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch

網路管理器正在嘗試覆蓋您的靜態配置設置。以 root 或 sudo 使用者身份執行：

service NetworkManager stop

如果您沒有服務，請嘗試：

/etc/init.d/NetworkManager stop

此外，您可以將靜態介面設置為不由 NetworkManager 管理，這是我在 CentOS 配置中所做的，只需添加以下行

NM_CONTROLLED=no

到您的靜態配置文件。您的靜態配置文件沒有該行，這意味著 NetworkManager 將嘗試控制這些介面而不是忽略它們。

有關禁用和/或解除安裝 NM的參考資訊，請參閱此處。
