CentOS 7.x CentOS 7.x and DNF package management vs YUM

Centmin Mod has future plans to support Fedora OSes as well using DNF package manager instead of YUM. But thanks to @Revenge's reminder that CentOS 7.x can also install and run DNF package manager besides YUM.

So who else has tried DNF instead or with YUM on CentOS 7 ?

Guess DNF history list only lists DNF installs packages so can't track already installed YUM packages.

Wow YUM provides at 7.79s and 287,220 KB versus DNF provides at 0.96s and 65,052 KB !

Amazing, DNF would speed up CentOS 7 based Centmin Mod installs greatly I would imagine. Seems from most YUM vs DNF commands, DNF is 6x times faster and using 1/2 the memory compared to YUM !

Would need to figure out DNF's equivalent for YUM priorities plugin as it's used to ensure all Centmin Mod installed 3rd party YUM repos don't conflict etc. From cheat sheet - yum priorities plugin is natively supported in DNF Yum to DNF Cheatsheet - FedoraProject !

Code:

yum-plugin-priorities    dnf    part of standard dnf; see priority option in man dnf.conf

 

Ah didn't realise that for dnf !

Code (Text):

dnf list dnf | tr -s ' '

Installed Packages
dnf.noarch 0.6.4-2.el7 @System

Started a separate 123.09beta01-dnf test branch to see

 

i'd hoping it's as simple as

Code (Text):

if [[ "$CENTOS_SEVEN" = '7' && "$DNF_ENABLE" = [yY] ]]; then
  yum -y install epel-release
  yum -y install dnf
  YUMDNFBIN='dnf'
else
  YUMDNFBIN='yum'
fi

then replace all referenced yum commands with $YUMDNFBIN so that when you set DNF_ENABLE='y', it uses dnf on CentOS 7 only otherwise falls back to yum command.

 

Yeah it will be optional for now if i do implement it - just how well it works if not with DNF that's all. It is for speed and memory usage reasons though and it's a total separate 123.09beta01-dnf branch testing so won't affect anyone using 123.09beta01 branch

And if CentOS in future does use DNF, at least I'd have a head start for testing

 

Yeah RHEL/CentOS have alot of legacy stuff in the name of 'stable'. Testing DNF on CentOS 7 has been quite revealing how much faster it is. Though DNF is very very slow compared to YUM when it comes to processing broken mirror links etc - YUM seems to handle that better. Or maybe it's old DNF 0.6.4 specific ?

 

seems DNF folks have a testing CentOS /RHEL 7 dnf 2.0 repo too Fresh DNF for RHEL 7 and CentOS 7 | DNF

might be on dnf 2.0.0 right now Index of /results/@rpm-software-management/dnf-centos/epel-7-x86_64/00506228-dnf/ will check it out too

FYI, so far with 123.09beta01-dnf branch testing of DNF for some select YUM routines, I've shaved off between 120-220 seconds of initial install time with DNF 0.6.4 via EPEL repo. Will check out DNF 2.0.0+ as well

Interesting anyway this is all just testing to see what's what

DNF 2.0 based 123.09beta01-dnf branch install time on local virtualbox CentOS 7.3 install

Code (Text):

---------------------------------------------------------------------------
Total Curl Installer YUM or DNF Time: 78.5393 seconds
Total YUM Time: 54.897235956 seconds
Total YUM or DNF + Source Download Time: 109.2106
Total Nginx First Time Install Time: 188.2923
Total PHP First Time Install Time: 392.6298
Download Zip From Github Time: 7.8265
Total Time Other eg. source compiles: 420.1615
Total Centmin Mod Install Time: 1110.2942
---------------------------------------------------------------------------
Total Install Time (curl yum + cm install + zip download): 1196.6600 seconds
---------------------------------------------------------------------------

About same as DNF 0.6.4 install times. The non-DNF usual install times are between 1,250-1,390 seconds on my local virtualbox instance - so up to 200 seconds faster

 

Moved 123.09beta01-dnf branch testing to my 2GB OpenVZ user and seems the CentOS 7 image has some 32bit i686 packages that conflict with dnf 2.0.0 dependencies !

Error Summary

seems DNF ignores /etc/yum.conf exclusions for 32bit packages so need to add an exclusion entry to /etc/dnf/dnf.conf

 

hmm more testing on 2GB OpenVZ VPS and seems it's a mixed bag as DNF is faster than YUM if all repo mirrors are working and fast but if repo mirrors are broken and need cycling through alternate mirrors or if mirror location is slow, then DNF seems alot slower than YUM is tackling the issues. Which means you could end up with slower overall Centmin Mod install times with DNF if such issues exist than YUM. Will try another test server to see if I can reproduce the issues.

 

If anyone else is curious and wants to test the DNF experimental branch, 123.09beta01-dnf on a test VPS/server with CentOS 7, you can install Centmin Mod 123.09beta01-dnf branch using command line

updated: March 31, 2017 123.09beta01-dnf changes have been merged into 123.09beta01 so to test

123.09beta01 branch with default disabled DNF_ENABLE='n'

Code (Text):

curl -sL https://github.com/centminmod/centminmod/raw/123.09beta01/installer.sh | bash

to test 123.09beta01 branch with DNF enabled, DNF_ENABLE='y', use the command but set persistent config file before running

Code (Text):

mkdir -p /etc/centminmod/
echo "DNF_ENABLE='y'" > /etc/centminmod/custom_config.inc
curl -sL https://github.com/centminmod/centminmod/raw/123.09beta01/installer.sh | bash

Could be different servers have different results for DNF enabled vs DNF disabled package installed Centmin Mod LEMP stacks Just remember only CentOS 7 supports using DNF

 

@Jimmy, if one of your OVH Gaming i7 servers is free, would be interested to see what install times DNF vs non-DNF get

 

ooh very much appreciated

what's your local machine specs ? that would be one fast machine

need all the speed I can get, FYI just testing DNF branch I have so far tested initial installs at least 40 times now @1000-1300 seconds/install
