A shell script for creating a new emqx node for an existing one.
It simply copies the existing emqx directory to new one and then changes the port configs in it.
Usage:
➜ cd _rel
➜ ls
emqx one_more_emqx.sh
➜ ./one_more_emqx.sh emqx2

.EMQX 5.0 uses HOCON formatted configs and supports changing the configs using envioronment variables. So this script is not needed any more.
- Duplicate the emqx directory to
emqx2.
cp emqx emqx2
- Start the emqx2:
cd emqx2
