Ubuntu网络配置——vlan+bonding
1. 普通网络配置
root@MXY-10-155:~#cat /etc/network/interfaces
auto lo
iface loinet loopback
auto em1
iface em1inet static
address10.26.10.155
netmask255.255.255.0
auto em2
iface em2inet static
address120.132.86.155
netmask255.255.255.224
gateway120.132.86.158
2. Vlan配置
1） 环境准备
apt-getinstall vlan
modprobe8021q
echo“8021q”>> /etc/modules
2） 配置文件
auto em1.100
iface em1.100 inet static
address 100.0.100.2
netmask 255.255.255.0
vlan-raw_device em1
3） 交换机打trunk
4） 重启服务器
3. 网络绑定
1） 环境准备
apt-get install ifenslave
echo “bonding” >> /etc/modules
2） 网络配置
vi /etc/network/interfaces
auto bond0
iface bond0 inet static
address 192.168.2.3
netmask 255.255.255.0
gateway 192.168.2.1
post-up ifenslave bond0 eth0 eth1
pre-down ifenslave -d bond0 eth0 eth1
可以直接删除原因来的eth0 eth1配置信息
然后重启服务器
4. 网卡绑定+vlan
1） 环境准备
apt-get install vlan ifenslave
echo “8021q” >> /etc/modules
echo “bonding” >> /etc/modules
2） 配置网络
auto lo
iface loinet loopback
auto em1
iface em1inet manual
bond-masterbond0
auto em2
iface em2inet manual
bond-masterbond1
auto em3
iface em3inet manual
bond-masterbond0
auto em4
iface em4inet manual
bond-masterbond1
autobond0
ifacebond0 inet manual
bond-mode4
bond-miimon100
bond-slavesnone
autobond1
ifacebond1 inet manual
bond-mode4
bond-miimon100
bond-slavesnone
autobond0.588
ifacebond0.588 inet static
address10.25.44.6
netmask255.255.255.0
vlan-raw-devicebond0
autobond0.202
ifacebond0.202 inet static
address10.25.63.6
netmask255.255.255.0
vlan-raw-devicebond0
autobond1.7
ifacebond1.7 inet static
address180.96.44.6
netmask255.255.255.0
gateway180.96.44.254
vlan-raw-devicebond1
autobond1.201
ifacebond1.201 inet static
address10.25.64.6
netmask255.255.252.0
vlan-raw-devicebond1
3） 重启MAC更换问题
当重启后，bond0和bond1的mac可能会发生变化，但交换机中arp表刷新时间比较慢，会导致重启后无法连上的问题
解决方法：
a. 人工刷新交换机arp表
b. 开机后主动ping网关，让交换机主动更新arp表
4） 重启后结果确认
