Can you provide instuctions on how to install ab on a fedora distro with or without installing the apache web server? With yum or compiling from source.


Install apr-util(need to run ab):

yum install apr-util

Install yum-utils:

yum install yum-utils

Download httpd an extract ab:

mkdir ~/httpd
cd ~/httpd
yumdownloader httpd
rpm2cpio httpd-2.2.3-43.el5.centos.3.i386.rpm | cpio -idmv
mv usr/bin/ab /usr/bin/ab
cd ~
rm -rf ~/httpd

Run ab:

ab http://google.ru/

    On ubuntu you could do sudo apt-get install apache2-utils – adrian7 Feb 27 '15 at 17:46
  • On Arch -- pacman -S apr-util – bobah Oct 27 '18 at 9:56

On my CentOS 6.2, this worked:

sudo yum install httpd-tools

This should help you. It depends upon on Apache Portable Runtime library and APR-util library


  • I actually tried that before I posted the answer, but hasn't been updated and it's not compatible with late versions of APR - No matter what, I couldn't get it to compile. – arnorhs Feb 28 '11 at 11:08

For those who came here looking for Apache Benchmark (ab) binary, you should know that ab can be slow sometimes (testing nginx for example). Also, it requires apr-util to be installed (with sudo), and there is no standalone binary to download.

Instead, I'd recommend an alternative - wrk - it is faster and requires no dependencies:
