CentOS / RHEL

These are specific notes for installing PEcAn on RedHat/CentOS and will be referenced from the main installing PEcAn page. You will at least need to install the build environment and Postgres sections. If you want to access the database/PEcAn using a web browser you will need to install Apache. To access the database using the BETY interface, you will need to have Ruby installed.

This document also contains information on how to install the Rstudio server edition as well as any other packages that can be helpful.

Install build environment

cd $RUBY_APPLICATION_HOME
export $NETCDF_URL=http://www.gfd-dennou.org/arch/ruby/products/ruby-netcdf/release/ruby-netcdf-0.6.6.tar.gz
export $NETCDF_DIR=/usr/local/netcdf
gem install narray
export NARRAY_DIR="$(ls $GEM_HOME/gems | grep 'narray-')"
export NARRAY_PATH="$GEM_HOME/gems/$NARRAY_DIR"
cd $MY_RUBY_HOME/bin
wget $NETCDF_URL -O ruby-netcdf.tgz
tar zxf ruby-netcdf.tgz && cd ruby-netcdf-0.6.6/
ruby -rubygems extconf.rb --with-narray-include=$NARRAY_PATH --with-netcdf-dir=/usr/local/netcdf-4.3.0
sed -i 's|rb/$|rb|' Makefile
