So, you want to run some website benchmarks from your Mac, do you? Well, good news and bad news. The good news is that your Mac already has it installed, but the bad news is that it is broken. If you've run the command now, you'll probably seen the following error message:
$ ab -n 1 http://www.google.com/ This is ApacheBench, Version 2.3 <$Revision: 655654 $> Copyright 1996 Adam Twiss, Zeus Technology Ltd, http://www.zeustech.net/ Licensed to The Apache Software Foundation, http://www.apache.org/ Benchmarking www.google.com (be patient)...apr_socket_recv: Connection reset by peer (54)</pre> To fix this, you'll want to run the following commands. In my example, the latest version of Apache is 2.4.3, but by the time you read this it may be a newer version, so just in case, <a href="http://apache.mirrors.pair.com/httpd/" target="_blank">download the latest Apache</a> from their website. <pre><code class="bash">ruby <(curl -fsSkL raw.github.com/mxcl/homebrew/go) # install homebrew brew install pcre # install PCRE, required by Apache wget http://apache.mirrors.pair.com/httpd/httpd-2.4.3.tar.bz2 # download Apache tar -xzvf httpd-2.4.3.tar.bz2 # extract Apache cd httpd-2.4.3 # enter Apache directory ./configure && make # configure and compile Apache sudo mv /usr/sbin/ab /usr/sbin/ab.bak # backup old ApacheBench sudo cp support/ab /usr/sbin/ # install new ApacheBench ab -n 1 http://www.google.com/ # test new ApacheBench
There ya go! This fixes ApacheBench in OS X Lion. I'm not sure if this also affects Mountain Lion.
