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
nmcli con add type bond-slave ifname p1p2

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
