這篇文章主要介紹了Linux使用ip link命令設置bond方式,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

設置bond的方法有很多種，其中通過命令行ip link設置就是其中一種，只不過這種設置方式不會持久化，當重啟服務器或重啟網(wǎng)絡服務就會失效。

2、設置步驟

【1】創(chuàng)建bonding接口

ip link add bond0 type bond

查看創(chuàng)建的bond接口：

[root@xxx network-scripts]# ip link show bond0
19: bond0: <BROADCAST,MULTICAST,MASTER> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000
    link/ether 1e:ce:ba:1e:f5:d3 brd ff:ff:ff:ff:ff:ff

【2】設置bonding模式

ip link set bond0 type bond mode active-backup miimon 100 #設置冗余備份模式，miimon為檢測物理鏈路時間間隔，單位毫秒

查看bond信息：

[root@xxx network-scripts]# cat /proc/net/bonding/bond0 
Ethernet Channel Bonding Driver: v3.7.1 (April 27, 2011)

Bonding Mode: fault-tolerance (active-backup) #負載均衡模式
Primary Slave: None
Currently Active Slave: None #當前激活接口，無
MII Status: down
MII Polling Interval (ms): 100  #檢測物理鏈路時間間隔
Up Delay (ms): 0
Down Delay (ms): 0
Peer Notification Delay (ms): 0

【3】添加物理網(wǎng)口到bonding接口

ip link set p112p1 down
ip link set p112p1 master bond0
ip link set p112p2 down
ip link set p112p2 master bond0

查看聚合口信息：

[root@xxx network-scripts]# ip link show p112p1
4: p112p1: <NO-CARRIER,BROADCAST,MULTICAST,SLAVE,UP> mtu 1500 qdisc mq master bond0 state DOWN mode DEFAULT group default qlen 1000
    link/ether 00:0d:48:4e:9f:e5 brd ff:ff:ff:ff:ff:ff
[root@xxx network-scripts]# ip link show p112p2
5: p112p2: <NO-CARRIER,BROADCAST,MULTICAST,SLAVE,UP> mtu 1500 qdisc mq master bond0 state DOWN mode DEFAULT group default qlen 1000
    link/ether 00:0d:48:4e:9f:e5 brd ff:ff:ff:ff:ff:ff

【4】激活bonding接口

ip link set p112p1 up
ip link set p112p2 up
ip link set bond0 up

查看bond信息：

[root@xxx network-scripts]# cat /proc/net/bonding/bond0 
Ethernet Channel Bonding Driver: v3.7.1 (April 27, 2011)

Bonding Mode: fault-tolerance (active-backup)
Primary Slave: None
Currently Active Slave: p112p1  #當前使用接口
MII Status: up
MII Polling Interval (ms): 100
Up Delay (ms): 0
Down Delay (ms): 0
Peer Notification Delay (ms): 0

Slave Interface: p112p1
MII Status: up
Speed: 1000 Mbps
Duplex: full
Link Failure Count: 0
Permanent HW addr: 00:0d:48:4e:9f:e5
Slave queue ID: 0

Slave Interface: p112p2
MII Status: up
Speed: 1000 Mbps
Duplex: full
Link Failure Count: 0
Permanent HW addr: 00:0d:48:4e:9f:e6
Slave queue ID: 0

3、解除步驟

【1】關閉bond接口

ip link set bond0 down

查看bond0接口狀態(tài)：

[root@xxx ~]# ip link show bond0
11: bond0: <BROADCAST,MULTICAST,MASTER> mtu 1500 qdisc noqueue state DOWN mode DEFAULT group default qlen 1000
    link/ether 00:0d:48:4e:9f:e5 brd ff:ff:ff:ff:ff:ff

【2】接觸從屬接口

ip link set p112p1 nomaster
ip link set p112p2 nomaster

查看從接口狀態(tài)：

[root@xxx ~]# ip link show p112p1 
4: p112p1: <BROADCAST,MULTICAST> mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000
    link/ether 00:0d:48:4e:9f:e5 brd ff:ff:ff:ff:ff:ff
[root@xxx ~]# ip link show p112p2
5: p112p2: <BROADCAST,MULTICAST> mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000
    link/ether 00:0d:48:4e:9f:e6 brd ff:ff:ff:ff:ff:ff

查看bond信息：

[root@xxx ~]# cat /proc/net/bonding/bond0 
Ethernet Channel Bonding Driver: v3.7.1 (April 27, 2011)

Bonding Mode: fault-tolerance (active-backup)
Primary Slave: None
Currently Active Slave: None
MII Status: down
MII Polling Interval (ms): 100
Up Delay (ms): 0
Down Delay (ms): 0
Peer Notification Delay (ms): 0

【3】刪除bond接口

ip link del bond0 type bond

查看bond信息，不存在：

[root@xxx ~]# cat /proc/net/bonding/bond0
cat: /proc/net/bonding/bond0: No such file or directory
