The setting
I have downloaded rabbitMQ and used it on an EC2 14.04 machine for a few days.
The setting was simple - I downloaded the Binary .tar.gz, opened it, and typed:
sbin/rabbitmq-server
RabbitMQ started and everything worked fine.
The problem
When I opened the machine this morning and tried to start rabbitMQ the same way, I got:
ubuntu rabbitmq-server: erl: not found
What have I tried
First, I was looking for erl:
$ locate erl | grep "erl$" | grep -v perl
/usr/bin/erl
/usr/bin/run_erl
/usr/bin/to_erl
/usr/share/doc/erlang-xmerl
But:
$ ls /usr/bin/erl
ls: cannot access /usr/bin/erl: No such file or directory
This means that erlang was there a few hours ago, before the last update of locate, but was somehow deleted!
I have re-installed erlang using apt-get and everything works well.
The question
Why was erlang deleted from my machine? How can I prevent this from happening in the future?
