高级网络控制

一、链路聚合

设置备用网卡，当其中一块损坏时，能保证服务器正常上网。

bond方式（支持2块）

nmcli connection delate eth0

配置两块网卡，删除ip

nmcli connection add con-name bond0 ifname bond0 type bond ip4 172.25.254.109/24

nmcli connection add con-name eth0 ifname eth0 type bond-slave master bond0

nmcli connection add con-name eth1 ifname eth1 type bond-slave master bond0

watch -n 1 'cat /proc/net/bonding/bond0'

team方式（最多支持8块）

nmcli connection add type team con-name team0 ifname team0 config '{"runner":{"name":"activebackup"}}' ip4 172.25.254.109/24

nmcli connection add con-name eth0 ifname eth0 type team-slave master team0

nmcli connection add con-name eth1 ifname eth1 type team-slave master team0

watch -n 1 teamdctl team0 state

二、桥接

文件模式编辑

vim /etc/sysconfig/network-scripts/ifcfg-br0

DEVIECE=enp0s25

ONBOOT=yes

BOOTROTO=none

BRIDGE=br0

vim /etc/sysconfig/network-scripts/ifcfg-enp0s25

DEVICE=br0

ONBOOT=yes

BOOTROTO=none

TYPE=Bridge

IPADDR=172.25.254.9

PREFIX=24

命令模式编辑

brctl addbr br0

ifconfig br0 172.25.254.100 netmask 255.255.255.0

ping 172.25.254.250

brctl addif br0 eth0

brctl show

删除桥接

ifconfig br0 down

brctl delif br0 eth0

brctl delbr br0

brctl show
