Abstract

The invention provides a method for realizing automatic configuration of NFT under a system, which belongs to the field of network data transmission. The method has the advantages that the NFT function is automatically configured under Linux, so that the test time is saved, the tester is saved, and the test resources can be more reasonably distributed.

Description

A method for automatically configuring NFT under the system

technical field

The invention relates to network data transmission technology, in particular to a method for realizing automatic configuration of NFT under the system.

Background technique

Due to the rapid development of the network, it is very important to achieve stable network data transmission in high-end industries such as finance. Because the NFT function can realize that after the switch is down, another switch can replace the work and the data transmission will not be disconnected. However, the configuration of NFT functions is particularly important.

There are multiple network cards on the server. NFT realizes that one network card is in an active state and can transmit data streams. Another network card or network port can quickly take over the work of the network card in case of a problem with the network card, ensuring that the data stream will not be disconnected. , has important applications in finance, banking and other industries.

Contents of the invention

In order to solve the above problems, the present invention proposes a method based on the LINUX platform to automatically configure NFT under the system.

Technical scheme of the present invention is:

A method for automatically configuring NFT under the system,

After running the script, enter the corresponding configured network port and IP, and the required configuration files will be created automatically, and the relevant files existing in the system will be modified. All configurations will take effect after the system restarts.

Borrow the shell script to automatically create and configure related files under the linux system, manually input the network port and IP to be configured, and realize all configurations of the NFT system on the server to realize the NFT function of the server.

script content

Close the built-in service module of the system:

service iptables stop

chkconfig NetworkManager off

service NetworkManager stop

Display the network port and network card name information of the network card:

lspci | grep -i ether | cut -d " " -f4-9 >> 1

ifconfig | grep eth | cut -d " " -f 1 >> 2

paste 1 2 > 3

cat 3

Enter the network port and IP to be selected:

read -p "input the first eth" first

read -p "input the second eth" second

read -p “input the IP between 192.168.0.1-254” IP

Automatically create configuration files:

cd /etc/sysconfig/network-scripts/

rm -rf ifcfg -eth $first

touch ifcfg -eth $first

Automatically write relevant parameters to the configuration file

echo 'DEVICE=eth$first' >> ifcfg-eth$first

echo 'BOOTPROTO=none' >> ifcfg-eth$first

echo ' >> ifcfg-eth$first

echo 'MASTER=bond0' >> ifcfg-eth$first

echo 'SLAVE=yes' >> ifcfg-eth$first

echo 'USERCTL=no' >> ifcfg-eth$first

echo 'NM_CONTROLLED=no' >> ifcfg-eth$first

rm -rf ifcfg -eth $second

touch ifcfg-eth $second

echo 'DEVICE=eth$second' >> ifcfg-eth$second

echo 'BOOTPROTO=none' >> ifcfg-eth$second

echo ' >> ifcfg-eth$second

echo 'MASTER=bond0' >> ifcfg-eth$second

echo 'SLAVE=yes' >> ifcfg-eth$second

echo 'USERCTL=no' >> ifcfg-eth$second

echo 'NM_CONTROLLED=no' >> ifcfg-eth$second

touch ifcfg-bond0//Create a configuration file for bond0 and add setting parameters

echo 'DEVICE=bond0' >> ifcfg-bond0

echo 'BOOTPROTO=none' >> ifcfg-bond0

echo ' >> ifcfg-bond0

echo 'BROADCAST=192.168.0.255' >> ifcfg-bond0

echo 'IPADDR=$IP' >> ifcfg-bond0

echo 'NETMASK=255.255.255.0' >> ifcfg-bond0

echo 'NETWORK=192.168.0.0' >> ifcfg-bond0

echo 'USERCTL=no' >> ifcfg-bond0

echo ' BONDING_OPTS=”mode=1 miimon=100” ’ >> ifcfg-bond0//Set the parameter to NFT

Modify the existing configuration files of the system

echo 'alias bond0 bonding' >> /etc/modprobe.d/dist.conf

echo 'options bonding mode=1 miimon=100 primary=eth0'>> /etc/modprobe.d/dist.conf

Add bond parameter to system startup file

echo 'ifensalve bond0 eth$first eth$second' >> /etc/rc.local//

reboot // system restart

The beneficial effect of the present invention is

Complete the NFT automatic configuration under the Linux system without manual intervention; the automatic configuration of the NFT function under Linux saves testing time, saves testers, and can allocate testing resources more reasonably.
