Linux使用ip link命令设置bond方式
作者：在成都搬砖的鸭鸭
这篇文章主要介绍了Linux使用ip link命令设置bond方式,具有很好的参考价值,希望对大家有所帮助,如有错误或未考虑完全的地方,望不吝赐教
1、介绍
设置bond的方法有很多种，其中通过命令行ip link设置就是其中一种，只不过这种设置方式不会持久化，当重启服务器或重启网络服务就会失效。
2、设置步骤
【1】创建bonding接口
ip link add bond0 type bond
查看创建的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】设置bonding模式
ip link set bond0 type bond mode active-backup miimon 100 #设置冗余备份模式，miimon为检测物理链路时间间隔，单位毫秒
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) #负载均衡模式 Primary Slave: None Currently Active Slave: None #当前激活接口，无 MII Status: down MII Polling Interval (ms): 100 #检测物理链路时间间隔 Up Delay (ms): 0 Down Delay (ms): 0 Peer Notification Delay (ms): 0
【3】添加物理网口到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 #当前使用接口 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、解除步骤
【1】关闭bond接口
ip link set bond0 down
查看bond0接口状态：
[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】接触从属接口
ip link set p112p1 nomaster ip link set p112p2 nomaster
查看从接口状态：
[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】删除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
