配置Bond

配置bond接口文件

注意：做bond之前先将网卡配置文件备份
网卡： 2块

a.去到配置文件目录

1 | [root@ela2 ~]# cd /etc/sysconfig/network-scripts/
2 | [root@ela2 network-scripts]# vim ifcfg-bond0
DEVICE=bond0
TYPE=Ethernet0
ONBOOT=yes
NM_CONTROLLED=no
BOOTPROTO=none
IPADDR=x.x.x.x
PREFIX=24
IPV6INIT=no
USERCTL=no
GATEWAY=x.x.x.1
3 | [root@ela2 network-scripts]# vim ifcfg-eth0
DEVICE=eth0
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=no
BOOTPROTO=none
IPV6INIT=no
USERCTL=no
MASTER=bond0
SLAVE=yes
4 | [root@ela2 network-scripts]# vim ifcfg-eth1
DEVICE=eth1
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=no
BOOTPROTO=none
IPV6INIT=no
USERCTL=no
MASTER=bond0
SLAVE=yes

2.bonding 参数

[root@ela2 ~]# vim /etc/modprobe.d/bond0.conf
alias  bond0 bonding
options bonding mode=0 miimon=100

3.重启网络服务

[root@ela2 ~]#  systemctl  restart  network

4.查看网卡的速率

1 | ethtool bond0
Settings for bond0:
        Supported ports: [ ]
        Supported link modes:   Not reported
        Supported pause frame use: No
        Supports auto-negotiation: No
        Supported FEC modes: Not reported
        Advertised link modes:  Not reported
        Advertised pause frame use: No
        Advertised auto-negotiation: No
        Advertised FEC modes: Not reported
        Speed: 2000Mb/s
        Duplex: Full
        Port: Other
        PHYAD: 0
        Transceiver: internal
        Auto-negotiation: off
        Link detected: yes

5、解除Bond0

a.删除bondind参数

1 | cd/etc/modprobe.d/
2 | rm -rf  bond0.conf 

b.删除bond的配置文件

1 | cd /etc/sysconfig/network-scripts/
2 | rm -rf ifcfg-bond0

c.还原网卡的配置文件

DEVICE=eth0
TYPE=Ethernet
ONBOOT=yes
BOOTPROTO=none
NAME=“eth0”
