對p1p1 p1p2兩張網卡做bond步驟
1) 做之前請對各網卡配置進行備份
1 使用root賬號登錄服務器
2 cp p1p1 p1p2 網卡的初始配置到tmp 目錄下，進行備份。
--------------------------------------------------------------
[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 爲物理網卡的名字
bond的mode如下：
balance-rr (0) --輪詢模式（bond默認的模式）
active-backup (1) --主備模式（常用）
balance-xor (2)
broadcast (3)
802.3ad (4) --聚合模式
balance-tlb (5)
balance-alb (6)
--------------------------------------------------------------
3) 修改bond0網卡配置
修改下面表格中標紅的內容
---------------------------------------------------------------
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 ---將原來的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 ---配置分配給服務器的IP地址
PREFIX=24 --配置子網掩碼
GATEWAY=192.168.80.1 ---配置網關
保存並退出
---------------------------------------------------------------
4) 重啓網絡
systemctl restart network –重啓網絡服務
cat /proc/net/bonding/bond0 ---查看bond0接口的相關信息
----------------------------------------------------------------
[root@XACR-aliware04 network-scripts]# cat /proc/net/bonding/bond0

---到此就完成bond配置了---
