How to Configure Network Static IP Address and Manage Services on RHELCent. OS 7. 0. This scope of this tutorial is to explain how we can edit and make changes to Network Configurations on RHELCent. OS 7. 0 from command line only, and, more specific how we can set up a Static IP addresses 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 RHELCent. OS 7. 0 system hostname. Configure Static IP in Linux. Also 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. Requirements. RHEL 7. Minimal System Installation. Active RHEL 7. 0 Subscriptions and Functional Repositories. Cent. OS 7. 0 Minimal System Installation. Also be aware that most of configurations offered by editing system files should not be performed from a remote location using SSH service until you establish an continue and reliable network connection using a fixed IP address. Step 1 Disable Unwanted System Services.

Install wget in Linux. Download Game Pop Superstar Jared. Install net tools in Linux. Install lsof in Linux. After the tools have installed run ifconfig to get your Network Interfaces settings and status, and, then run netstat or lsof command to check what services are running by default on our server. Command. 3. The netstat command output is pretty self explanatory and shows a list of sockets associated with their running program name. 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 server.

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 command and use it often. If you used 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. If you want to get a list of all started services run service command and for an exhaustive report use systemctl. List All Services in Linux. List All Services Report. To manage services run systemctlcommand using the most important switches start, stop, restart, reload, disable, enable, show, list dependencies, is enabled etc. Search the worlds information, including webpages, images, videos and more. Google has many special features to help you find exactly what youre looking for. Also, another important feature that systemctl command can also run on remote server through SSH service on aspecified host using H option and perform the same actions as locally. For example, see the command and screenshot below. H remotehost start remoteservice. Run systemctl on Remote Server. Step 2 Configuring Static IP and Set Hostname. Before starting editing Network Interface Card system files make sure that from now on and until you set static IP, you have physical or any other type of access to your server, because this step requires bringing down your network interface and connections. Although it can be done smoothly without disrupting your connectivity and activate connection after reboot.

For beginning start by stopping and disabling Network. Manager service. Dont run this command if you still want to maintain connection. Network. Manager. Network. Manager. Now move to etcsysconfignetwork scripts path, open and choose your Network Interface you want to assign static IP for editing to get all NICs names use ifconfig a or ip a commands. Use the next template to edit file and make sure that ONBOOT statement is set on YES, BOOTPROTO is set to static or none and dont change HWADDR and UUID values provided by default. HWADDR0. 0 0. C 2.

To test if your hostname is correctly set use hostname command. For short name. For FQDN mame. Step 3 Use Network Manager Text User Interface. Network. Manager Text User Interface TUI tool, nmtui, is a RHEL intuitive tool which provides a text interface to configure networking by controlling Network Manager, which helps editing advanced network settings such as assign static IP addresses to Network Interfaces, activate or disable a connection, edit WI FI connections, set your system hostname or create advanced Network interfaces like Infini. Band, bond, bridge, team or VLAN. Network. Manager tui is installed by default in RHELCent. OS 7. 0, but if for some reasons its missing issue the following command to install it. Network. Manager tui. To start Network Manager Text User Interface run nmtui command and use TAB or arrow keys to navigate through and press Enter to select an option. If you want to directly edit or connect a specific interface run the following options. Network. Manager Text User Interface. Select Network Connection.
