We are working as a LINUX Server/System administrator but most of us don’t know about DNF command and its feature. In this article we are going to explain about DNF and its usage. DNF stands for Dandified yum. We can tell DNF, the next generation of yum package manager (Fork of Yum) using hawkey/libsolv library for backend. Aleš Kozumplík started working on DNF since Fedora 18 and its implemented/launched in Fedora 22 finally.
Now, we are going to play on our Fedora 22 box to explain and cover mostly used DNF commands with examples.

DNF Installation in RHEL/CentOS/Scentific linux
By default DNF was enabled in Fedora systems. For RHEL/CentOS/Scentific linux, use the below command to install DNF.# enable epel repository #
root@2daygeek [~]# yum install epel-release
or
root@2daygeek [~]# yum -y install epel-release
# install dnf #
root@2daygeek [~]# yum install dnf
1) Common syntax/file location for DNF
See below for common syntax/ file location of DNF.# Common syntax for DNF #
root@2daygeek [~]# dnf [options] [commands] [package name]
# most popular dnf commands #
root@2daygeek [~]# [autoremove check-update clean distro-sync downgrade group help history info install list makecache provides reinstall remove repolist repository-packages search updateinfo upgrade upgrade-to]
# dnf config file location #
root@2daygeek [~]# /etc/dnf/dnf.conf
# dnf cached file location #
root@2daygeek [~]# /var/cache/dnf
2) Install a Package or packages
Use the below command to install any package or packages on your system. In this case i’m going to install apache, MariaDB-server, MariaDB-client. Every time DNF ask your confirmation to install the corresponding package. if you want to avoid the confirmation you can do by this adding -y option with dnf.# Install a single package #
root@2daygeek [~]# dnf install httpd
or
root@2daygeek [~]# dnf -y install httpd
# Install more than one packages #
root@2daygeek [~]# dnf install MariaDB-server MariaDB-client
or
root@2daygeek [~]# dnf -y install MariaDB-server MariaDB-client
Output:
root@2daygeek [~]# dnf install httpd
