| # SOME INFOS : fairly standard (debian) init script. | |
| # Note that node doesn't create a PID file (hence --make-pidfile) | |
| # has to be run in the background (hence --background) | |
| # and NOT as root (hence --chuid) | |
| # | |
| # MORE INFOS : INIT SCRIPT http://www.debian.org/doc/debian-policy/ch-opersys.html#s-sysvinit | |

| # | |
| # 1) Don't forget to also modify the COMMENTED fields in the "### BEGIN INIT INFO" | |
| # below (don't uncomment them) if you wish to install system-wide with update-rc.d | |
| # eg: provides, Short-Description, Description | |
| # | |
| # 2) replace APPNAME with the name of the app you are running | |
| # | |
| # 3) copy the renamed/modified script(s) to /etc/init.d | |
| # chmod 755, | |
| # | |
| # 4) if you wish the Daemon to be lauched at boot / stopped at shutdown : | |
| # INSTALL : update-rc.d scriptname defaults | |
| # (UNINSTALL : update-rc.d -f scriptname remove) | |
| # | |
| # 5) it is a god idea to run it with some auto restart manager | |
| # and multi-threader like | |
| # https://github.com/LearnBoost/cluster | |
| # | |
| # 6) based on : Debian /etc/init.d/skeleton | |
| # modified by : Peter Host (www.oghme.com) | |
| # modified for nave and many pids by : Shimon Doodkin (doodkin.com) | |

| # Short-Description: DEBIAN initscript for node.js servers/apps | |
| # Description: ex : proxy server is a node.js http server listening on | |
| # port 8080 (relayed from 80 by iptables). It balances | |
| # http requests between the main nodejs server | |
| # (nodejs.mydomain.com:8000), the static file-server | |
| # (static.mydomain.com) and the legacy apache server | |
| # (apache.mydomain.com) and possibly other servers | |
| # place this file in /etc/init.d. | |

| # or choose one of your own liking. | |
