CentOS 7 网卡bond配置

56341

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。

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

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

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

[iyunv@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

[iyunv@XACR-aliware04 network-scripts]# vim ifcfg-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 –重启网络服务

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

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

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