System Setting: a solution that cannot be set when the IP address is set using setup

How to Set an IP address that cannot be set when you set an IP address through setup in Linux? There are multiple methods for setting an IP Address: 1. You can directly edit the configuration file, generally, you can use the ifconfig command (for temporary use) in/etc/sysconfig/network-scripts/ifcfg-ethx (permanently saved) 2) 3. You can also use the setup menu tool (permanently saved) to have higher requirements on the first two, that is, to be familiar with Linux, but using the setup tool is relatively simple, it is a menu-based tool that can also adapt to a large number of beginners. But sometimes, if you run setup without the Network Setting option, you cannot set the IP address. This is because no module commands for network settings are installed, if you cannot use a machine that can connect to the Internet, you can use it in the yum environment. The yum install-y system-config-network-tui installation is complete, you can use and set it. If the command cannot be found even when you run setup, it is because the setup Toolkit is not installed. For some minimum installation, in this case, you only need yum install-y setup setuptool.
