POSIX compatible Installer for OpenTox IST/ALU Services
=======================================================
A) It is assumed that your system is configured for sudo to gain root privileges.
B) It is assumed that your system is configured for using non-free packages.
This is a POSIX-compliant (not limited to a particular shell) Opentox installer. Please report bugs always via GitHub.
Here are some of my goals when writing the installer:
- Safe (existence of all the binaries will be checked before running, apart from GNU Core Utils)
- Idempotent (multiple execution does not change a thing)
- Atomic (return value of each non-elemtary action is asserted to be TRUE)
- Encapsulated (everything is installed in a sub-directory in $HOME)
- Logged (all non-elemtary actions are logged)
Even if we officially support only *one* distro (currently Debian 6.0.1), I tested the installer successfully on various Ubuntus. In the README at the top are the requirements of the installer. By default, everything is installed to $HOME/opentox-ruby (=OT_PREFIX). The configs go to OT_PREFIX/.sh_<Package>_ot.sh for each package.
After running the installer, configure the system by editing the startup file of your favorite shell (in my case, BASH with the file ~ /. bashrc) to include ~/.opentox-ui.sh (in my case with 'source ...'). This file is the only one that the installer creates outside OT_PREFIX. Thus, the system is fully configured: If you now open a new shell, all environment variables will be adjusted.
To start the system I run the following (but that is not part of the installer):
sudo nohup $HOME/opentox-ruby/redis-2.2.2/src/redis-server $HOME/opentox-ruby/redis-2.2.2/redis.conf &
sudo nohup $HOME/opentox-ruby/nginx/sbin/nginx -c $HOME/opentox-ruby/nginx/conf/nginx.conf &
To uninstall the system simply delete the link from the startup file: Done. To save disc space delete directory OT_PREFIX.
Anyone can run multiple Opentox versions on the same machine: Just install again, but to a different OT_PREFIX. The switch works manually: Include the sh_<Package>_ot.sh files from the desired OT_PREFIX in $HOME/opentox-ui.sh (only one installation may be activated at any time).
Some useful scripts to put in your ~/.bashrc in case you are using bash (assuming OT_PREFIX is '~/opentox-ruby'):
# Load server config
otconfig() {
source $HOME/.opentox-ui.sh
}
# Update the development version
otupdate() {
START_DIR=`pwd`
otconfig
cd $HOME/opentox-ruby/www/opentox
for d in `find -not -name "." -type d -maxdepth 1 2>/dev/null`; do echo $d ; cd $d ; git pull ; echo ; cd - ; done

if [ -h $LINK_DIR ]; then

fi
rake install
if ! [ -h $LINK_DIR ]; then
echo "Warning! Your lib $LINK_DIR is no symlink. Linking back for you..."
rm -rf "$LINK_DIR~"
mv "$LINK_DIR" "$LINK_DIR~"
ln -sf $HOME/opentox-ruby/www/opentox/opentox-ruby/lib `echo ${LINK_DIR::${#LINK_DIR}-4}`
fi
echo "Please execute 'otstart' to restart."
cd "$START_DIR"

otstart() {
