# You should place this script in user's home bin dir like :
# /home/redmine/bin/server_puma.sh
#
# Normally the user's bin directory should be in the PATH.
# If not, add this in /home/redmine/.profile :
#
# ------------------>8
# #set PATH so it includes user's private bin if it exists
# if [ -d "$HOME/bin" ] ; then
#   PATH="$HOME/bin:$PATH"
# fi
# ------------------>8
#
#
# This script *must* be run by the Redmine user so
# switch user *before* running the script :
# root$ su - redmine
#
# Then :
# redmine$ server_puma.sh start
# redmine$ server_puma.sh stop
# redmine$ server_puma.sh restart
