BASH - Sync DB | Prod -> Local
#!/bin/bash
# Big thanks to @sam_h for this! Works like a charm.
#
# This script assumes you have ssh access to a remote server
# Both databases are backed up to sql files in the same directory
# this script is executed from.
# Usage:
# 1. Make sure this file is executable with `chmod +x mysqlsync`
# 2. Set the credentials for the variables at the top
# (Remember, no spaces around the '=' sign)
# 3. Run it from a directory where you'd like the backup files to go:
# `./mysqlsync`
#
# You may also rename this file which makes it easier per project.
# SSH credentials
SSH_USER=user
SSH_SERVER=site.com
# Remote DB credentials
REMOTE_USER=user
REMOTE_PASS=pass
REMOTE_HOST=localhost
REMOTE_DB=database_name
# Local DB credential
LOCAL_USER=root
LOCAL_PASS=root
LOCAL_HOST=localhost
LOCAL_DB=database_name
