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]# 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 ---------------------------------------------------------------- [root@XACR-aliware04 network-scripts]# cat /proc/net/bonding/bond0 Ethernet Channel Bonding Driver: v3.7.1 (April 27, 2011)
Bonding Mode: fault-tolerance (active-backup) Primary Slave: None
Currently Active Slave: p1p2 MII Status: up
MII Polling Interval (ms): 100 Up Delay (ms): 0 Down Delay (ms): 0
Slave Interface: p1p1 MII Status: up Speed: 10000 Mbps Duplex: full
Link Failure Count: 2
Permanent HW addr: f4:e9:d4:9a:f1:a0 Slave queue ID: 0
Slave Interface: p1p2 MII Status: up Speed: 10000 Mbps Duplex: full
Link Failure Count: 2
Permanent HW addr: f4:e9:d4:9a:f1:a2 Slave queue ID: 0
---------------------------------------------------------------- ---到此就完成bond配置了---
