The system I'm using is Centeros 7, and the following red is the command
1.setup command
Log in to the system as root, type setup into the graphical interface, if prompted without the Setup command, type:yum install Setuptool installs the graphical tool, all the way yes.
2. After the transfer is complete, additional installation is required:
#可以发现执行setup后不全, then install one for system service management
Yum install Ntsysv #再安装个防火墙, along with Setup's firewall settings, network settings
Yum Install iptables #安装setup中配套的防火墙设置
Yum Install System-config-securitylevel-tui #继续安装setup中配套的网络设置的时候, prompted without this package, in fact CENTOS7 network settings using Nmtui can open yum install System-config-network-tui3. The command for the network settings is Nmtui
4. View the configuration file with the NIC name Ens33Vi/etc/sysconfig/network-scripts/ifcfg-ens33, this will enter the edit mode of the NIC configuration named Ens33.
