As we know, there are some boring tasks while deploy Django project, like create db, do migrations and so on, here I wrote a shell script to auto do these things

#!/bin/bash

# The shell is used to do some prepare tasks for deploying TMS, including:

# (1) create new user to run TMS;

# (2) create database and add privileges;

# (3) extract software to the new user's home directionay;

# (4) modify the system database related configuration;

# (5) create necessary tables for TMS;

# (6) add administartor for TMS;

# (7) run MQ as a daemon;

# (8) deploy TMS with nginx.

# Note: please exec this sh as root.
