mdid_init_d

mdid_init.sh

#!/bin/bash

### this is a script for a user (with sudo privs if launching mysql) to run. 
### it's a script I use for developing on a mac, so it will need tweaking to run
### on linux systems (i.e. it will need all of the init.d, service stuff addded)
###
### it requires an argument - start|stop|restart|procs|pids
### start|stop|restart are as expected, 
### procs invokes pgrep -fl for solr, rabbitmq, mysql and "python manage.py runworkers"
### pids invokes pgrep -f for solr, rabbitmq, mysql and "python manage.py runworkers"
