根据官方文档Red_Hat_Enterprise_Linux-7-Networking_Guide-en-US用nmcli做起来还是相当容易的。下面把俺的步骤贴下。
1、查看目前网卡的名称和状态。#nmcli device status DEVICE TYPE STATE CONNECTION eno16777736 ethernet connected eth1 eno33554992 ethernet disconnected -- eno50332216 ethernet disconnected -- lo loopback unmanaged -- 2、配置网卡bond0和模式主备 nmcli connection add type bond con-name bond0 ifname bond0 mode balance-xor
nmcli connection modify bond0 bond.options mode=2 修改办法
第一种模式：mod=0 ，即：(balance-rr)Round-robin policy（平衡抡循环策略）cisco交换机？
第二种模式：mod=1，即： (active-backup)Active-backup policy（主-备份策略）
第三种模式：mod=2，即：(balance-xor)XOR policy（平衡策略）华为交换机配置Eth-Trunk dis interface Eth-Trunk 2 According to SA-XOR-DA,
第四种模式：mod=3，即：broadcast（广播策略）
第五种模式：mod=4，即：(802.3ad)IEEE 802.3ad Dynamic link aggregation（IEEE802.3ad 动态链接聚合）
第六种模式：mod=5，即：(balance-tlb)Adaptive transmit load balancing（适配器传输负载均衡）
第七种模式：mod=6，即：(balance-alb)Adaptive load balancing（适配器适应性负载均衡）

3、将物理网卡绑定到bond0
# nmcli connection add type bond-slave ifname eno1 master bond0Connection 'bond-slave-eno50332216' (3f07e767-24ea-4e7e-a9f7-61efa9aa0664) successfully added.
# nmcli connection add type bond-slave ifname eno2 master bond0Connection 'bond-slave-eno33554992' (8149c24f-4926-4531-844f-36a526e1baec) successfully added. 4、启用绑定的物理网卡# nmcli connection up bond-slave-eno1Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/4) # nmcli connection up bond-slave-eno2Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/5)5、启用bond网卡
#nmcli connection up bond0Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/6)现在网卡已经绑好启用#sudo yum install net-tools
#sudo ifconfig -a
#sudo yum install iptables-services.*
6、地址之类的可以后加
nmcli con mod bond0 ipv4.addresses "10.0.59.4/24" ipv4.gateway "10.0.59.254" ipv4.dns "114.114.114.114"
nmcli con mod bond0 ipv4.method manual 也可以通过nmcli添加，大家查下手册即可Usage: nmcli connection { COMMAND | help }COMMAND := { show | up | down | add | modify | edit | delete | reload | load } show [--active] [[id | uuid | path | apath] <ID>] ... up [[id | uuid | path] <ID>] [ifname <ifname>] [ap <BSSID>] down [id | uuid | path | apath] <ID> add COMMON_OPTIONS TYPE_SPECIFIC_OPTIONS IP_OPTIONS modify [--temporary] [id | uuid | path] <ID> ([+|-]<setting>.<property> <value>)+ edit [id | uuid | path] <ID> edit [type <new_con_type>] [con-name <new_con_name>] delete [id | uuid | path] <ID> reload load <filename> [ <filename>... ]#nmcli connection show bond0
