Hi all

I was trying to isntall RApache last week but ran into strnge problems that no one else seems to be experiencing. At least I couldn't find anything after extensive googling.

First off, the machine I'm installing on looks like this:

Dell Optiplex 745
32 bit
2GB RAM
Fedora 15
httpd -v
Server version: Apache/2.2.21 (Unix)
Server built:   Sep 13 2011 13:46:23
R:
R-2.14.0-3.fc15.i686
perl
                perl-5.12.4-164.fc15.i686

What I did was the following:


·         Downloaded the package, rapache-1.1.15.tar.gz

·         Ran configure --with-apache2-apxs=/usr/sbin/apxs, make, make install.

·         Added this to my httpd.conf:

o       LoadModule R_module /usr/lib/httpd/modules/mod_R.so

o

o       # Output R errors and warnings to the browser

o       ROutputErrors

o

o       # Displays information about rapache and R

o       <Location /RApacheInfo>

o          SetHandler r-info

o       </Location>
Also added the Directory directives but commented them when I was trying to get this to work. I figured if I couldn't see the r-info, nothing would work.

Then I navigated to  /RApacheInfo on the machine and got an internal server error. The log says this:

[Thu Jan 19 14:37:33 2012] [error] [client 10.101.77.150] rApache Notice!
No RApache Directive specified for 'SetHandler r-info'

I figured that had to be coming from the R module. I tried searching for this error message but it seemed like no one has been experiencing it.

After this I decided to revisit the configure script. I ran it again, this time I added the -with-R switch:

./configure --with-apache2-apxs=/usr/sbin/apxs --with-R=/usr/bin/R

I examined the output and saw that there seemed to be an error but still the script ended with apparent success.

I don't know if this error is critical but I couldn't get rid of it.

I'm not an R user myself. Not yet at least. Just the IT guy in my company. But the R people can't seem to contain themselves over RApache and really want to see it working.

Hope you can point me in the right direction.

Take care,
  Gisli
