Setup CentOS 7 / Fedora
Useful quick reference for getting a viable Fedora or CentOS 7 setup.
In all cases these steps should be run as root:
sudo -s
Starting with FC23 Yum has upgraded to Dandified Yum aka DNF. Since this guide is for either CentOS 7 or FC23... if you just run:
alias yum=dnf
It when running in Fedora, it should remove the constant warnings.
add yourself to the wheel (so you can sudo -s)
usermod -a -G wheel youruser
change sudo rules to no password required, if you want, on wheel
- run visudo
- search for %wheel
- comment current rule
- uncomment the one with NOPASSWD
EPEL (CentOS ONLY)
yum -y install epel-release
rpm -i http://mirrors.rit.edu/fedora/epel/7/x86_64/e/epel-release-7-5.noarch.rpm
Disable GUI (optional)
systemctl set-default multi-user.target
Enable GUI (once you want it back)
systemctl set-default graphical.target
