centos6 双网卡远程安全配置和删除bond

 双网卡绑定配置

// 修改网卡配置文件

cd /etc/sysconfig/network-scripts

cp ifcfg-lo ifcfg-bond0

vi ifcfg-bond0

DEVICE=bond0
IPADDR=10.1.2.3
NETMASK=255.255.255.0
ONBOOT=yes
NAME=bond0
BOOTPROTO=none
USERCTL=no
GATEWAY=10.1.2.1
DNS1=10.10.10.10
DNS2=10.10.10.11

 

vi ifcfg-eth0

DEVICE=eth0
HWADDR=00:0C:29:96:E1:07
TYPE=Ethernet
UUID=5fa57856-a597-4f64-af31-13ed16e28615
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=none
USERCTL=no
MASTER=bond0
SLAVE=yes

 

vi ifcfg-eth1

DEVICE=eth1
HWADDR=00:0C:29:96:E1:11
TYPE=Ethernet
UUID=fb8dd150-605c-4eb2-bcbf-a92b32217863
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=none
USERCTL=no
MASTER=bond0
SLAVE=yes

 

// 新建bonding.conf文件，将bonding和bond0关联
vi /etc/modprobe.d/bonding.conf

alias bond0 bonding
options bond0 miimon=100 mode=0

// 重启网卡查看，一切就绪
service network restart

 

 双网卡bond解绑

cd /etc/sysconfig/network-scripts

rm -f /etc/sysconfig/network-scripts/ifcfg-bond0
rm -f /etc/modprobe.d/bonding.conf

vi ifcfg-eth0

DEVICE=eth0
HWADDR=00:0C:29:96:E1:07
TYPE=Ethernet
UUID=5fa57856-a597-4f64-af31-13ed16e28615
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=none
USERCTL=no
IPADDR=10.1.2.3
NETMASK=255.255.255.0
GATEWAY=10.1.2.1
DNS1=10.10.10.10
DNS2=10.10.10.11

 

vi ifcfg-eth1

DEVICE=eth1
HWADDR=00:0C:29:96:E1:11
TYPE=Ethernet
UUID=fb8dd150-605c-4eb2-bcbf-a92b32217863
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=none
USERCTL=no
IPADDR=192.168.1.201
NETMASK=255.255.255.0

 

最后执行：

rmmod bonding && service network restart

完成解绑

全程远程操作，安全！
