rapache configuration

Installing redis

This package requires the redis in-memory database to be installed. See http://redis.io for details on that. It should be listening on the standard port, 6379.

Installing rapache

See the rapache website for details there

Configuring rapache

We need to install gWidgetsWWW2.rapache first.

Then configure rapache along the lines of:

## only if not already configured for rapache
LoadModule R_module /usr/libexec/apache2/mod_R.so

## Simple configuration. Here we modify value. Could also move script and edit.
RSourceOnStartup 'system.file("rapache", "startup.R", package="gWidgetsWWW2.rapache")'
## override to look in more places than default
REvalOnStartup "options('gWidgetsWWW2.rapache::script_base'=c(system.file('examples', package='gWidgetsWWW2.rapache'), '/tmp/','/var/www/gw_scripts'))"

## LimitRequestBody puts cap on upload size. Set to 0 for unlimited
<Location /gw>
      LimitRequestBody 1024000
        SetHandler r-handler
        ## from system.file("rapache", "www2.R", package="gWidgetsWWW2.rapache")
    RFileHandler /Library/Frameworks/R.framework/Versions/2.15/Resources/library/gWidgetsWWW2.rapache/rapache/www2.R
</Location>

The module location and location of www2.R depend on the installation. These came from a Mac OS X Mountain Lion install.

The two files ("startup.R" and "www2.R") can (should?) be moved out of the package tree and edited, especially the "startup.R" file. When done, you can edit some variables that effect the operation.
