這篇文章主要介紹了Linux nmcli設(shè)置bond的過程,具有很好的參考價值,希望對大家有所幫助,如有錯誤或未考慮完全的地方,望不吝賜教

1、介紹

nmcli是NetworkManager提供的網(wǎng)絡(luò)管理工具，nmcli設(shè)置的bond可以持久化，因為會寫入配置文件，下面我們就來通過nmcli來配置bond聚合口。

2、配置步驟

【1】創(chuàng)建bond連接

[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 'bond0' (cb2d7d4b-2ce8-41d8-b027-2d5b1032e237) successfully added.

可以發(fā)現(xiàn)/etc/sysconfig/network-scripts產(chǎn)生了一個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】添加從屬接口

[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 added.
[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.

查看產(chǎn)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=2cef6090-07b7-485f-b140-f553185ae994
DEVICE=p112p2
ONBOOT=yes
MASTER=bond0
SLAVE=yes

【3】激活bond口

查看bond口和聚合口連接信息：

[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，當(dāng)連接名稱重復(fù)時，建議用uuid去激活：

[root@xxx network-scripts]# nmcli conn up bond0
Connection successfully 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
