Steps to configure IP address in CentOS: View the current network configuration: ip addr Edit the network configuration file: sudo vi /etc/sysconfig/network-scripts/ifcfg-eth0 Change the IP address: Edit IPADDR= Line to change the subnet mask and gateway (optional): Edit NETMASK= and GATEWAY= Line to restart the network service: sudo systemctl restart network verification IP address: ip addr
How to configure IP address in CentOS
Step 1: Check the current network configuration
Run the following command to view the current network configuration:
<code>ip addr</code>
This command displays all network interfaces and their current configuration.
Step 2: Edit the network configuration file
Find the network interface to which you want to change the IP address. It is usually an Ethernet interface called eth0
. Edit the configuration file for this interface:
<code>sudo vi /etc/sysconfig/network-scripts/ifcfg-eth0</code>
Step 3: Change the IP address
Find and edit the following line in the configuration file:
<code>IPADDR=192.168.1.100</code>
Replace 192.168.1.100
with the required IP address.
Step 4: Change the subnet mask and gateway
You can also change the subnet mask and gateway as needed:
<code>NETMASK=255.255.255.0 GATEWAY=192.168.1.1</code>
Step 5: Restart the network service
After making changes to the network configuration, you need to restart the network service to make the changes take effect:
<code>sudo systemctl restart network</code>
Step 6: Verify IP Address
Verify the new IP address using the following command:
<code>ip addr</code>
This command should display the network interface with the new IP address.

1. The Origin of .NETCore When talking about .NETCore, we must not mention its predecessor .NET. Java was in the limelight at that time, and Microsoft also favored Java. The Java virtual machine on the Windows platform was developed by Microsoft based on JVM standards. It is said to be the best performance Java virtual machine at that time. However, Microsoft has its own little abacus, trying to bundle Java with the Windows platform and add some Windows-specific features. Sun's dissatisfaction with this led to a breakdown of the relationship between the two parties, and Microsoft then launched .NET. .NET has borrowed many features of Java since its inception and gradually surpassed Java in language features and form development. Java in version 1.6
