Centos7 双端口 Bond & Vlan

服务器两块网卡做 Bond，并配置 Vlan 为 321

|| 关闭 NetworkManager

# systemctl stop NetworkManager

# systemctl disable NetworkManager

|| 修改网卡配置

1- bond 配置

# vim /etc/modprobe.d/bond.conf
alias bond0 bonding
options bond0 miimon=100 mode=1

2- 需要 bond 的两个端口

# vim /etc/sysconfig/network-scripts/ifcfg-enp130s0f0
TYPE=Ethernet
BOOTPROTO=dhcp
DEFROUTE=yes
NAME=enp130s0f0
UUID=2140300b-1780-4058-9e09-bfe90c34b272
DEVICE=enp130s0f0
ONBOOT=yes
MASTER=bond0
SLAVE=yes

# vim /etc/sysconfig/network-scripts/ifcfg-enp130s0f1
TYPE=Ethernet
BOOTPROTO=dhcp
NAME=enp130s0f1
UUID=a59ad333-13bf-4389-99e2-edc2b3e4c649
DEVICE=enp130s0f1
ONBOOT=yes
MASTER=bond0
SLAVE=yes

3- 添加 bond0

# vim /etc/sysconfig/network-scripts/ifcfg-bond0
DEVICE=bond0
TYPE=Ethernet
ONBOOT=yes
BOOTPROTO=static

4- 配置 Vlan 321

# vim /etc/sysconfig/network-scripts/ifcfg-bond0.321
DEVICE=bond0.321
TYPE=Ethernet
ONB00T=yes
BOOTPROTO=none
IPADDR=10.125.144.37
NETMASK=255.255.255.0
GATEWAY=10.125.144.1
DNS1=114.114.114.114
VLAN=yes

5- 重启

# reboot

|| 测试

分别断开再连接两网口

1- 测试 enp130s0f0

# ifdown enp130s0f0

# tail -f /var/log/messages
