The question for the similar issue may have been asked for many times in stackoverflow. However after searching, I found no answer solve my problem. So I post it here to seek for your help.
My system is Ubuntu 14.04. After setup master and minion (named "minion1"), I test salt on master using the command
salt 'minion1' test.ping
I got the following error:
minion1:
Minion did not return. [Not connected]
Following others' advices, I have tested the following commands:
On minion, I firstly remove the previous master key by:
rm /etc/salt/pki/minion/minion_master.pub
and restart minion, but still failed. So we eliminate the case of unmatched master key.
On minion, I execute
salt-call test.ping
to get:
local:
True
so the communication between master and minion is good.
On minion, I firstly stop salt-minion using command:
service salt-minion stop
and run it in debug mode using command:
salt-minion -l debug
to get the following return:

This problem has being hanging there for some time, could anyone help me on that? Thanks in advance!
Edit:
I found a strange thing after the before post. When I run the command
service salt-minion status
Oddly enough it returned:
salt-minion stop/waiting
if I further check using: ps aux| grep salt-minion, I found no process of salt-minion is running. I wonder that's why salt minion1 test.ping cannot return correct value. However, no matter what I did (service salt-minion start), I could never make the return of service salt-minion status shows salt-minion is start/running. What should I do now?
