This is a unix wrapper around the erlang vm.
#!/bin/bash
# This is a unix wrapper around the erlang vm. It provides the following functionality:
#
# * Spawns in foreground
# * Handle SIGHUP and call RELOADFUNC
# * Handle SIGTERM SIGQUIT and SIGINT telling to the vm to quit
# * Dies if the vm dies (for example kernel killing because out of memory)
#
# Forks and improvements are welcome.

CouchDB 2.* on Ubuntu 16.04
# See also: http://docs.couchdb.org/en/latest/cluster/index.html
# Before you can add nodes to form a cluster, you have to have them listen on a public ip address
# and set up an admin user (use same admin:password for all nodes).
# Do this, once per node:
# If you have installed couchdb in /opt (else change the Path)
cd /opt/couchdb/etc
cp local.ini local.ini.orig
cp vm.args vm.args.orig
