Here’s a simplified step-by-step guide to change the IP address in CentOS 7:
1. Identify the network interface you want to change the IP address for. You can use the `ip addr` command to see the available network interfaces.
2. Open the configuration file for the desired network interface using a text editor. The configuration files are typically located in the `/etc/sysconfig/network-scripts/` directory.
sudo nano /etc/sysconfig/network-scripts/ifcfg-eth0
3. In the configuration file, locate the `IPADDR` and `PREFIX` (or `NETMASK`) lines, and update them with the new IP address and subnet mask.
4. Save the changes and exit the text editor.
5. Restart the network service for the changes to take effect.
sudo systemctl restart network
6. Alternatively, you can bring down the network interface and then bring it back up to apply the changes.
sudo ifdown eth0
sudo ifup eth0
That’s it! This simple process should help you change the IP address on your CentOS 7 system.
