Further, the step 2 includes:
Step 21: editor ifcfg-eth0, ifcfg-eth1 file；
Step 22: creation ifcfg-bond0 file, and ifcfg-bond0 is copied to
Under the path /etc/sysconfig/network-script/；
Step 23: editor modprobe.conf, and modprobe.conf copied to/path etc/ under.
Further, after the step 2 further include: close firewall.
Further, after the step 23 further include: by ordering the service network restart service of restarting.
Further, double network interfaces on the node to be measured use same MAC Address.
The prior art is compared, the beneficial effects of the invention are that: a kind of double network interfaces of integrated network card proposed by the present invention
Bonding test method, double network interfaces on two nodes to be measured are successfully configured to dynamic link mode by interchanger, herein
Under kind mode, when extracting single network interface cable of a node to be measured, second node to be measured can lead to this section still with ping
Point, SSH remote access will not disconnect.If thus can verify that out that one of network interface damages another on node to be measured
Network interface can directly substitute its function, it is not necessary to do extra configuration, improve the stability of server, be network transmission
Load balance and fault-tolerant ability are provided.
It can be seen that compared with prior art, the present invention implementing with substantive distinguishing features outstanding and significant progress
Beneficial effect be also obvious.
Detailed description of the invention
Attached drawing 1 is the method flow diagram of the embodiment of the present invention one.
Attached drawing 2 is the method flow diagram of the embodiment of the present invention two.
Specific embodiment
It explains with reference to the accompanying drawing to a specific embodiment of the invention.
Embodiment one:
A kind of bonding test method of the double network interfaces of integrated network card as shown in Figure 1, includes the following steps:
Step 1: two nodes to be measured are established into connection by interchanger；
Step 2: bonding setting being carried out to double network interfaces of each node to be measured respectively；
Step 3: successively four network interfaces on two nodes to be measured carry out network-in-dialing test；If can be logical with ping and can be with
SSH remote access, then go to step 4；
Step 4: the cable of any network interface being disconnected, if two nodes to be measured still are able to ping and lead to, and can be with SSH
Remote access, then be successfully tested.
Long-term important affiliate of the Baidu as tide, performance and stability requirement to tide server are the most
Strictly.Baidu Xueye Rack project, requires more to come higher to network stabilization, not only needs for single network port performance pressure
Power needs are up to standard, also very strict for double network interface bonding test requests, and Rack background server stablizes network interface
Property requires high, if there is problem, may cause data access interaction and goes wrong or even occur loss of data.Pass through this
Embodiment is able to verify that the server under double network interface configurations, if one of network interface damages another network interface and can directly replace
For its function, it is not necessary to extra configuration is done, and in two network interfaces simultaneously use process, if one of network interface
Loading is excessively high, another network interface can go to share pressure, if loading very little, can automatically switch to 2 network interface fortune
Row, improves the stability of server, rationally utilizes resource, provides load balance and fault-tolerant ability for network transmission.
Embodiment one:
A kind of bonding test method of the double network interfaces of integrated network card as shown in Figure 2, includes the following steps:
Step 1: two nodes to be measured being established into connection by interchanger, for the network card configuration connecting on interchanger with node to be measured
Dynamic link.
Configuration method is as follows:
Enable
Configure terminal
Interface range gigabitEthernet 0/1-2
Port-group 1 mode active
Exit
Interface aggregateport 1
Switchport mode trunk
Exit
Wr
Order cat/etc/net/bonding/bond0 is executed, if display " Dynamic ", dynamic link configuration successful.
Step 2: two network interfaces corresponding with double network interfaces of node to be measured on interchanger are set as a group.
Step 3: bonding setting being carried out to double network interfaces of each node to be measured respectively.
The configuration method and configuration file of this step are as follows:
1. ifcfg-eth0 is edited, ifcfg-eth1 file, by taking ifcfg-eth0 as an example:
DEVICE=xgbe0
BOOTPROTO=static
ONBOOT=yes
MASTER=bond0
SLAVE=yes
2. creating ifcfg-bond0 file:
DEVICE=bond0
ONBOOT=yes
BOOTPROTO=static
IPADDR=192.168.12.30
NETMASK=255.255.255.0
GATEWAY=192.168.12.254
Ifcfg-bond0 is copied to/path etc/sysconfig/network-script/ under；
3. it is as follows to edit modprobe.conf file:
alias bond0 bonding
options bond0 miimon=100 mode=4 xmit_hash_policy=layer3+4
Modprobe.conf is copied to/path etc/ under；
4. by ordering the service network restart service of restarting；
5. closing firewall iptables-F.
Step 4: successively four network interfaces on two nodes to be measured carry out network-in-dialing test；If can it is logical with ping and
It can be remotely accessed with SSH, then go to step 5.
By this step ensure two nodes 4 network interfaces can ping it is logical, and can be remotely accessed with SSH.
Step 5: the cable of any network interface being disconnected, if two nodes to be measured still are able to ping and lead to, and can
It is remotely accessed, is then successfully tested with SSH.
Specifically: first disconnecting the cable of first one of network interface of node to be measured, second node to be measured is still
So can ping it is logical, and can be remotely accessed with SSH, then disconnect the cable of second one of network interface of node to be measured,
It is logical that first node to be measured still is able to ping, and can be remotely accessed with SSH, then is successfully tested
In addition, in the present embodiment, double network interfaces on node to be measured use same MAC Address.Interchanger is handed over using the StarNet 10,000,000,000
It changes planes.
A kind of bonding test method of the double network interfaces of integrated network card that the present embodiment proposes, is effectively verified on two nodes
Double network interfaces by interchanger success under dynamic link mode can configuration successful, also demonstrate in this mode, when pulling out
Out when single network interface cable of a node, second node can lead to this node still with ping, and SSH remote access will not break
It opens.And node can distribute by several network interfaces automatically according to current network load size and execute task, if wherein one
A network interface loading is excessively high, another network interface can go to share pressure, if loading very little, can automatically switch to 2
Network interface operation, if one of network interface damages another network interface and can directly substitute its function, it is not necessary to which it is extra to do
Configuration, improves the stability of server, provides load balance and fault-tolerant ability for network transmission.
With reference to the drawings and specific embodiments, the invention will be further described.It should be understood that these embodiments are merely to illustrate
The present invention rather than limit the scope of the invention.In addition, it should also be understood that, after reading the content taught by the present invention, this field
Technical staff can make various changes or modifications the present invention, and such equivalent forms equally fall within range defined herein.
