Activate the network interface using the ifup command of linux

Editor to share with you the use of linux's ifup command to activate the network interface, I hope you can learn a lot after reading this article, let's discuss it together!

The ifup command activates the specified network interface. The ifup command reads the configuration file of the relevant network interface in the / etc/sysconfig/network-scripts/ directory and activates the network interface according to the contents of the configuration file.

Note: the network interface name must be set in the / etc/sysconfig/network-scripts/ directory configuration file. If you change the network interface with the ifconfig command, the ifup command will not recognize it. Because the ifup command compares the parameters of the current network with the contents of the configuration file in / etc/sysconfig/network-scripts/.
