for a research project I needed to install RApache on my Mac OS X 10.6.4 (Snow Leopard) machine.
It did take some time, a lot of beeping in the video documentary, a lot of recompiles…
Here is the way to do it:
1. Install Gnu Fortran on your Mac
You need to install Gnu Fortran on your Mac, because you have to build R on your Mac to run RApache.
Fortunately, there is a nicely Mac-style installer available at
Go ahead and install it.
2. Install libapreq on your Mac
libapreq2 is a library for your Apache 2 installation. Download libapreq2-2.12 (or newer) here and install it via Terminal:
tar xzvf libapreq2-2.12.tar.gz cd libapreq2-2.12 ./configure make sudo make install
3. Build R
Go to your favorite CRAN-mirror (Georg-August Universität Göttingen) and download the source for R, e.g. R-2.11.1.tar.gz (section source code for all platforms). Now build R. Watch out for the configure option –enable-R-shlib!
tar xzvf R-2.11.1.tar.gz cd R-2.11.1 ./configure --enable-R-shlib make sudo make install
4. Install RApache
Download RApache from http://biostat.mc.vanderbilt.edu/rapache/downloads.html
Install RApache with the special configure option with-apache2-apxs!
tar xzvf rapache-1.1.9.tar.gz cd rapache-1.1.9 ./configure --with-apache2-apxs=/usr/sbin/apxs sudo make sudo make install
5. Reconfigure your Apache
Go to your Apache configuration file:
cd /private/etc/apache2/ sudo pico httpd.conf
(if you have TextMate installed, just use sudo mate httpd.conf)
now add the line after the other LoadModule entries in the httpd.conf file
LoadModule R_module libexec/apache2/mod_R.so
Add the following line for debugging just below
as well as (put this somewhere at the end of the conf-file:
# Prints out a nice report about R running within Apache <Location /RApacheInfo> SetHandler r-info </Location>
Restart Apache (open up Systempreferences, select Sharing and uncheck and check Websharing).
Now you should be able to go to
(you find the name of your computer in System preferences -> Sharing if you click on websharing: if websharing is running, it shows you a link to your computer – use the second link)
to get a nice info about RApache running on your system.
After that you have to reinstall R from CRAN again, because your regular R install will be broken. Hmmmm, I hope this gives all you RApache-Macheads enough headstart to come up with a cleaner solution.
