![]() ![]() If our default target is multi-user.target, it means that the GUI will not be loaded. We can check this by running: $ systemctl get-default There were ~1000 packages installed on a minimal CentOS 7 installation.Īlthough we installed the GNOME Desktop package group, the GUI will not be loaded by default on reboot. $ sudo yum groupinstall "GNOME DESKTOP" -y To do this, we’ll just have to install the GNOME Desktop package group, which will install all the packages required for the GUI installation. To uninstall MATE from your CentOS 7 machine, run the following commands: $ sudo yum groupremove -y "MATE Desktop" Xclients file in the directory of the user you’re connecting with: $ echo "mate-session" > ~/.Xclients $ sudo yum groupinstall -y "MATE Desktop" To install MATE, run the following commands: $ sudo yum install -y epel-release To uninstall XFCE from your CentOS 7 machine, run the following commands: $ sudo yum groupremove -y "Xfce" Now you can connect to the server using Remote Desktop Connection. Xclients file in the directory of the user you’re connecting with: $ echo "xfce4-session" > ~/.Xclients To install XFCE, run the following commands: $ sudo yum install -y epel-release Additionally, it has a very active community, so there are many customization options available. It’s fast, low on system resources, while still visually appealing. XFCE is one of the most lightweight desktop environments. NOTE: If you can’t connect via Remote Desktop Connection after you’ve installed the desktop environment, then open port 3389/tcp using the firewall-cmd command mentioned above. If you’re looking for a lightweight and resource friendly solution, install XFCE. In this guide we’ll try out XFCE, MATE, and GNOME. Now we can install the desktop environment we’ll be using. $ sudo firewall-cmd -reload Step 2 – Install Your Preferred Desktop Environment If you’re using FirewallD, then open port 3389/tcp for RDP: $ sudo firewall-cmd -add-port=3389/tcp -permanent Installing xRDP on CentOS 8: For an updated version of this tutorial for CentOS 8, along with installing additional desktop environments and configuring the remote desktop connection for speed, we recommend this article How to Connect to a CentOS 8 Server via Remote Desktop Connection using xRDP Step 1 – Install xRDP on CentOS 7įirst, update your package index: sudo yum -y update $ sudo yum install -y epel-release A machine running CentOS 7 with a minimum of 2GB RAM.Although not absolutely required, we recommend acting as a non-root sudo user when proceeding to make any major changes to your system.The name originates from the German word kupfernickel, which means "false copper" from the illusory copper color of the ore.

It is one of four elements that are ferromagnetic and is used in the production of various type of magnets for commercial use. Nickel is a hard and ductile transition metal that is considered corrosion-resistant because of its slow rate of oxidation. ![]() In its elemental form, nickel has a lustrous metallic silver appearance. The nickel atom has a radius of 124 pm and a Van der Waals radius of 184 pm. Nickel was first discovered by Alex Constedt in 1751. The number of electrons in each of nickel's shells is and its electron configuration is 3d 8 4s 2. Nickel (atomic symbol: Ni, atomic number: 28) is a Block D, Group 4, Period 4 element with an atomic weight of 58.6934.
