Linux Boot Process (RHEL 7 Latest)  From ServerGyan
 
17:43
Linux Boot Process (REHL 7) 1- The machine is powered on. The system firmware (BIOS --Basic Input/Output System or UEFI -- Unified Extensible Firmware Interface) runs POST, and starts to initialize some of the hardware. You can configure this using F2 on your system/ server. 2- The system firmware searches for a bootable device, either configured on BIOS or UEFI boot firmware or by searching master boot recored (MBR).This order is configured in BIOS. You can configure this using F2 screen for by pressing certain key combination. 3- The system firmware reads a boot loader from disk, then passes control of the system to boot loader. On REHL 7 this will be GRUB2 You can configure this using grub2-install 4- The boot loader loads configuration from disk and presents the user with possible configuration to boot. You can configure this using /boot/grub2/grub.cfg 5- Either user makes a choice or automatic timeout happens, the boot loader loads the configured KERNEL and INITRAMFS from disk and places then in memory. An INITRAMFS is a gzip-ed CPIO archive containing kernel modules for all hardware necessary at boot, init-scripts and more. ON RHEL 7, the INITRAMFS contains an entire usable system by itself. You can configure using: /etc/dracut.conf 6- The boot loader hands control of the system over to kernel, passing in any options specified on kernel command line in boot loader and the location of the INITRAMFS in memory. You can configure using: /etc/grub.d/ /etc/default/grub, and /boot/grub2/grub.cfg 7- Now the kernel initializes all hardware for which it can find a driver in the initramfs, then executes /sbin/init (as PID 1). On REHL 7 the initramfs contains a working copy of systemd as /sbin/init, as we all a udev daemon. Configure using init and command line parameters. 8- The systemd instance from the initramfs executes all unit of initrd.target target. This includes actual mounting on /sysroot configure using /etc/fstab 9- The kernel root file system is switched form initramfs root file system to system root file system that was previously mounted on /sysroot.systemd then re-executes itself using a copy of systemd installed on the system. 10- Systemd looks for a default target, either passed from the kernel command line or configured on the system, then starts (and stops) units to comply with the configuration for that target, solving dependencies between units automatically. In its essence, a systemd target is a set of units that should be activated to reach a desired system state. These targets will typically include at least a text-bases login or a graphical login screen with appear.

nmcli command-line tool for controlling NetworkManager - RHEL 7 - RHCSA
 
25:01
nmcli is a command-line tool for controlling NetworkManager and reporting network status. It can be utilized as a replacement for nm-applet or other graphical clients. nmcli is used to create, display, edit, delete, activate, and deactivate network connections, as well as control and display network device status. Scripts: Utilize NetworkManager via nmcli instead of managing network connections manually. nmcli supports a terse output format which is better suited for script processing. Note that NetworkManager can also execute scripts, called "dispatcher scripts", in response to network events. See NetworkManager(8) for details about these dispatcher scripts. Servers, headless machines, and terminals: nmcli can be used to control NetworkManager without a GUI, including creating, editing, starting and stopping network connections and viewing network status. #RHCSA #1_ON_TRENDING #LINUX_TUTORIAL NetworkManager stores all network configuration as "connections", which are collections of data (Layer2 details, IP addressing, etc.) that describe how to create or connect to a network. A connection is "active" when a device uses that connection's configuration to create or connect to a network. There may be multiple connections that apply to a device, but only one of them can be active on that device at any given time. The additional connections can be used to allow quick switching between different networks and configurations. Consider a machine which is usually connected to a DHCP-enabled network, but sometimes connected to a testing network which uses static IP addressing. Instead of manually reconfiguring eth0 each time the network is changed, the settings can be saved as two connections which both apply to eth0, one for DHCP (called default) and one with the static addressing details (called testing). When connected to the DHCP-enabled network the user would run nmcli con up default , and when connected to the static network the user would run nmcli con up testing. nmcli monitor nmcli connection {show | up | down | modify | add | edit | clone | delete | monitor | reload | load | import | export} [ARGUMENTS...] Youtube PlayLists Shell-Scripting: https://goo.gl/a1Hu3s Linux-Commands: https://goo.gl/QDoL7h RHCSA Certification: https://goo.gl/X2Ksqn Putty Software Tricks: https://goo.gl/MB1Do2 Linux OS: https://goo.gl/62p8s9 Follow Us on Social Media Telegram Group: https://goo.gl/KPvMda https://arkit.co.in/one-linux-tutorial/ Reddit: http://bit.ly/redditark https://goo.gl/mcUvef Mailing List: http://bit.ly/feedburnerark https://goo.gl/fb/WAU7JG Facebook: https://fb.com/linuxarkit https://goo.gl/2QN4sD LinkedIn: http://bit.ly/linkedark https://goo.gl/ZLcikC Twitter: https://twitter.com/aravikumar48 Google Plus: http://bit.ly/gplusark https://goo.gl/79zwX9

Red Hat Enterprise Linux 7 - Installation Walkthrough
 
07:45
In this demo, Mark Flitter provides a look into the RHEL 7 installer, including network configuration, setting package locations, and partitioning install disks. NOTE: This is a previously produced video which was published on the Red Hat Customer Portal around the time Red Hat Enterprise Linux 7 launched, and has been re-uploaded here on our official YouTube channel for the benefit of our viewers. While the installation process process is largely the same, "pre-release" or "testing" references in this video are the result of this walkthrough being filmed on the Release Candidate version of Red Hat Enterprise Linux 7 prior to it's launch.
