centos 7 static ip address configuration

List All Services in Linux List All Services ReportĦ. If you want to get a list of all started services run the service command and for an exhaustive report use systemctl. If you use Arch Linux then it should be a piece of cake to switch to systemd – although all init commands now are linked and pass-through systemd filter. You can, also, use old init commands to stop or disable services but since Red Hat now implements systemd process and service management, you should better get used to systemctl commands and use it often. Stop Postfix Service Stop Avahi Daemon Service # systemctl stop avahi-daemonĤ. Stop Postfix Service # systemctl stop postfix If, for example, our system will not be used as a mail service you can stop Postfix master daemon which runs on localhost and, also stop and disable other unwanted services using the following commands – the only service I advise not to stop or disable for now is SSH if you need remote control over the server. The netstat command output is pretty self-explanatory and shows a list of sockets associated with their running program name. RequirementsĪlso, be aware that most of the configurations offered by editing system files should not be performed from a remote location using SSH service until you establish a continued and reliable network connection using a fixed IP address.ģ. Configure Static IP in LinuxĪlso will show you, how we can manage or disable unwanted system services, such as Network Manager, which is no longer needed in-case you use a manual static IP configured on network scripts, Avahi-Daemon which is, also, not needed on a server and represents a seriously security gap, unless you installed the server on your Laptop and you want to instantly browse your network for other services, and on the final will present you Network Manager Text User Interface – nmtui, a system utility that can ease the job of editing your system network settings with advanced Interface configurations like creating Bond, Bridge, Team and VLAN Interfaces. The scope of this tutorial is to explain how we can edit and make changes to Network Configurations on RHEL/CentOS 8/7 from the command line only, and, more specifically how we can set up a Static IP address on network interfaces using system network-scripts, which is a must be configured to serve Internet-facing network services, and how to configure or change RHEL/CentOS system hostname.
