网卡绑定（bond）之子接口

服务器两张网卡需要做bond，并且bond后网卡需配置不同网段的地址，用于走不同流量，这个时候就可以采用起子接口的方式。

# 第一步：停掉NetworkManager服务

systemctl stop NetworkManager.service

systemctl disable NetworkManager.service

# 第二步：备份

cp /etc/sysconfig/network-scripts/ifcfg-enp176s0f0{,.bak}

cp /etc/sysconfig/network-scripts/ifcfg-enp176s0f1{,.bak}

# 第三步：将网卡协议改为none并设备未开机自启动，并做双网卡配置

sed -i 's/BOOTPROTO=dhcp/BOOTPROTO=none/' /etc/sysconfig/network-scripts/ifcfg-enp176s0f0

sed -i 's/ONBOOT=no/ONBOOT=yes/' /etc/sysconfig/network-scripts/ifcfg-enp176s0f0

echo "MASTER=bond0" >>/etc/sysconfig/network-scripts/ifcfg-enp176s0f0

echo "SLAVE=yes" >>/etc/sysconfig/network-scripts/ifcfg-enp176s0f0

 

sed -i 's/BOOTPROTO=dhcp/BOOTPROTO=none/' /etc/sysconfig/network-scripts/ifcfg-enp176s0f1

sed -i 's/ONBOOT=no/ONBOOT=yes/' /etc/sysconfig/network-scripts/ifcfg-enp176s0f1

echo "MASTER=bond0" >>/etc/sysconfig/network-scripts/ifcfg-enp176s0f1

echo "SLAVE=yes" >>/etc/sysconfig/network-scripts/ifcfg-enp176s0f1

# 第四步：配置网卡bond0

echo "DEVICE=bond0

TYPE=Ethernet

ONBOOT=yes

BOOTPROTO=static" >/etc/sysconfig/network-scripts/ifcfg-bond0

# 第五步：写模块文件，bond模式为mode 0

echo "alias bond0 bonding

options bond0 miimon=100 mode=0" >/etc/modprobe.d/bond.conf

# 加载模块

modprobe bonding

# 第六步：起子接口

# 起子接口bond0.201

vim /etc/sysconfig/network-scripts/ifcfg-bond0.201

DEVICE=bond0.201

TYPE=Vlan

PHYSDEV=bond0

ONBOOT=yes

BOOTPROTO=static

REORDER_HDR=yes

IPADDR=10.10.51.16

GATEWAY=10.10.51.1

NETMASK=255.255.255.0

DNS1=114.114.114.114

DNS2=8.8.8.8

VLAN=yes

VLAN_ID=201

 

# 起子接口bond0.401

vim /etc/sysconfig/network-scripts/ifcfg-bond0.401

DEVICE=bond0.401

TYPE=Vlan

PHYSDEV=bond0

ONBOOT=yes

BOOTPROTO=static

REORDER_HDR=yes

IPADDR=111.20.200.90

GATEWAY=111.20.200.89

NETMASK=255.255.255.0

DNS1=114.114.114.114

DNS2=8.8.8.8

VLAN=yes

VLAN_ID=401

 

# 加载模块并重启主机

modprobe 8021q

reboot
