IP configuration in CentOS7

CentOS 7.0 is a very new version. Many friends do not know how to install and configure CentOS 7.0, because CentOS has greatly improved with previous versions.

Note: up to now, the latest version of CentOS 7.x is CentOS 7.0. The following describes the specific installation and configuration process of CentOS 7.0.

After the installation is completed today, I realized that centos does not have a visual interface.

Enter the logon page

Enter the root account and press Enter.

Enter the root password set above and press Enter.

Note: After CentOS 7.0 is installed by default, network connections are not automatically enabled!
