CentOS 7 网卡bond配置

对p1p1 p1p2两张网卡做bond步骤

1)做之前请对各网卡配置进行备份

1 使用root账号登录服务器

2 cp p1p1 p1p2 网卡的初始配置到tmp 目录下，进行备份。

--------------------------------------------------------------

[root@XACR-aliware04 ~]# cd /etc/sysconfig/network-scripts/

[root@XACR-aliware04 network-scripts]# cp ifcfg-p1p1 /tmp

[root@XACR-aliware04 network-scripts]# cp ifcfg-p1p2 /tmp

--------------------------------------------------------------

2)使用nmcli命令配置bond

生成bond配置

--------------------------------------------------------------

nmcli con add type bond ifname bond0 mode 1

nmcli con add type bond-slave ifname p1p1 master bond0

nmcli con add type bond-slave ifname p1p2 master bond0

注：p1p1 p1p2 为物理网卡的名字

bond的mode如下：

balance-rr (0) --轮询模式（bond默认的模式）

active-backup (1) --主备模式（常用）

balance-xor (2)

broadcast (3)

802.3ad (4) --聚合模式

balance-tlb (5)

balance-alb (6)

--------------------------------------------------------------

3)修改bond0网卡配置

修改下面表格中标红的内容

---------------------------------------------------------------

cd /etc/sysconfig/network-scripts

[root@XACR-aliware04 network-scripts]# vimifcfg-bond-bond0

DEVICE=bond0

BONDING_OPTS=mode=active-backup

TYPE=Bond

BONDING_MASTER=yes

BOOTPROTO=static ---将原来的dhcp 改成static

DEFROUTE=yes

PEERDNS=yes

PEERROUTES=yes

IPV4_FAILURE_FATAL=no

NAME=bond-bond0

UUID=f4146d29-d694-4f13-ae59-56f940c7d120

ONBOOT=yes

IPADDR=192.168.80.7 ---配置分配给服务器的IP地址

PREFIX=24 --配置子网掩码

GATEWAY=192.168.80.1 ---配置网关

保存并退出

---------------------------------------------------------------

4)重启网络

systemctl restart network �C重启网络服务

cat /proc/net/bonding/bond0 ---查看bond0接口的相关信息

----------------------------------------------------------------

[root@XACR-aliware04 network-scripts]# cat /proc/net/bonding/bond0

---到此就完成bond配置了---
