Arvin's Howtos

After adding my new repository, yum update takes forever to finish: # yum update Loaded plugins: aliases, changelog, downloadonly, fastestmirror, filter-data, keys, kmod, list-data, protect-packages, protectbase, rhnplugin, security, tmprepo,               : verify, versionlock I noticed yum loading lots of plugins, so I disabled the yum plugins and issue resolved: # cat /etc/yum.conf |grep plugins plugins=0

I've recently installed CentOS 7 VM minimal and after installation finished and system rebooted I noticed there is no desktop installed. Here is the steps to install gnome via command line: 1. Install the Gnome desktop package group: # yum -y groups install "GNOME Desktop" 2. Switch to runlevel 5 for graphical environment # init 5 3. Set the graphical environment as default runlevel after rebooting system: # systemctl enable graphical.target --force rm '/etc/systemd/system/default.target' ln -s '/usr/lib/systemd/system/graphical.target' '/etc/systemd/system/default.target'
