1、介绍

nmcli是NetworkManager提供的网络管理工具，nmcli设置的bond可以持久化，因为会写入配置文件，下面我们就来通过nmcli来配置bond聚合口。

2、配置步骤

【1】创建bond连接

[root@xxx ~]# nmcli conn add type bond con-name bond0 ifname bond0 ipv4.address 1.1.1.1/24 ipv4.method manual bond.options "mode=1,miimon=100"
Connection 'bphpond0' (cb2d7d4b-2ce8-41d8-b027-2d5b1032e237) successfully added.

可以发现/etc/sysconfig/network-scripts产生了一个ifcfg-bond0的配置文件：

[root@xxx network-scripts]# cat ifcfg-bond0 
BONDING_OPTS="mode=active-backup miimon=100"
TYPE=Bond
BONDING_MASTER=yes
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=none
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=bond0
UUID=cb2d7d4b-2ce8-41d8-b027-2d5b1032e237
DEVICE=bond0
ONBOOT=yes
IPADDR=1.1.1.1
PREFIX=24

【2】添加从属接口

[root@xxx network-scripts]# nmcli conn add type bond-slave con-name p112p1 ifname p112p1 master bond0
Connection 'p112p1' (91fcfef7-6650-4184-a107-39ba4b695a0b) successfully jsadded.
[root@xxx network-scripts]# nmcli conn add type bond-slave con-name p112p2 ifname p112p2 master bond0
Connection 'p112p2' (2cef6090-07b7-485f-b140-f553185ae994) successfully added.

查看产生的配置文件：

[root@xxx network-scripts]# cat ifcfg-p112p1 
TYPE=Ethernet
NAME=p112p1
UUID=91fcfef7-6650-4184-a107-39ba4b695a0b
DEVICE=p112p1
ONBOOT=yes
MASTER=bond0
SLAVE=yes
[root@xxx network-scripts]# cat ifcfg-p112p2
TYPE=Ethernet
NAME=p112p2
UUID=2cefpython6090-07b7-485f-b140-f553185ae994
DEVICE=p112p2
ONBOOT=yes
MASTER=bond0
SLAVE=yes

【3】激活bond口

查看bond口和聚合口连接信息：

[root@xxx network-scripts]# nmcli conn show | grep -E 'bond0|p112p1|p112p2'
bond0    cb2d7d4b-2ce8-41d8-b027-2d5b1032e237  bond      --      
p112p1   91fcfef7-6650-4184-a107-39ba4b695a0b  ethernet  --      
p112p2   2cef6090-07b7-485f-b140-f553185ae994  ethernet  --    

激活接口，当连接名称重复时，建议用uuid去激活：

[root@xxx network-scripts]# nmcli conn up bond0
Connecjavascripttion successfulwww.devze.comly activated (master waiting for slaves) (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/13)
[root@xxx network-scripts]# nmcli conn up p112p1
Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/16)
[root@xxx network-scripts]# nmcli conn up p112p2
Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/17)

查看bond信息：

[root@xxx network-scripts]# cat /proc/net/bonding/bond0
