Tutorial on adding a physical Nic to a Linux server

Due to business needs, three Linux servers in the foreign data center need to add one physical Nic each. Previously, no Nic operation was performed on the physical server, which is a supplement of experience. Linux system version: ScientificLinux6.5x86 _ 64 Server model: Fujitsu suprimergyrx200s8 New Nic model: IntelI350-T2

Due to business needs, three Linux servers in the foreign data center need to add one physical Nic each. Previously, no Nic operation was performed on the physical server, which is a supplement of experience.

 

Linux: Scientific Linux 6.5 x86_64

Server model: fujitsu primergy RX200 S8

New Nic model: Intel I350-T2

 

The installation process is as follows:

The procedure is as follows:

1. power off the system power of three servers

2. field engineers install the physical network card on three servers and connect the network cable to the switch.

3. enable server power

4. check whether the Nic exists. because the system already has the NIC driver, it eliminates the hassle of compiling the driver. ifconfig-a can view all the NICs of the system and see that eth2 already exists.

5. enter the system's "/etc/sysconfig/network-scripts" directory to configure the new Nic file ifcfg-eth2, you can copy the existing eth1 configuration file as eth2, delete the hardware address and UUID, change DEVICE to eth2 and static IP address

6. enable the new Nic after confirmation, ifup eth2

7. run the ifconfig command to check whether the new Nic is enabled successfully.

 

So far, the operation of adding a physical Nic to the Linux server has been completed, and everything is better than expected. let's take a look at the Linux operating system's support for drivers of mainstream hardware, it saves most of the administrator's energy and time, focuses more on core businesses, and improves work efficiency!
