linux重启bond丢失IP

可以尝试重新配置bond，重启网络服务：

1. 首先，编辑/etc/sysconfig/network-scripts/ifcfg-bond0文件，添加如下内容：

DEVICE=bond0

BOOTPROTO=none

ONBOOT=yes

USERCTL=no

IPADDR=192.168.1.100

NETMASK=255.255.255.0

TYPE=Ethernet

BONDING_OPTS=\"mode=1 miimon=100\"

2. 编辑/etc/sysconfig/network-scripts/ifcfg-eth0文件，添加如下内容：

DEVICE=eth0

BOOTPROTO=none

ONBOOT=yes

MASTER=bond0

SLAVE=yes

USERCTL=no

3. 编辑/etc/sysconfig/network-scripts/ifcfg-eth1文件，添加如下内容：

DEVICE=eth1

BOOTPROTO=none

ONBOOT=yes

MASTER=bond0

SLAVE=yes

USERCTL=no

4. 重启网络服务：

# service network restart

[root@localhost ~]# service network restart

Shutting down interface bond0: ERROR: [ipv6_test_device_status] Missing parameter 'device' (arg 1)

[ OK ]

Shutting down interface em2: [ OK ]

Shutting down loopback interface: [ OK ]

Bringing up interface bond0: Device does not seem to be present, delaying initialization.

解决：

加载bonding模块

modprobe bonding

查看模块是否加载成功：

lsmod | grep bonding

再次重启网卡

service network restart
