#!/bin/bash

# USAGE: 
# 
#   sh import-mysql-db.sh
#   bash import-mysql-db.sh
#   
#   OR
#   
#   chmod +x import-mysql-db.sh
#   ./import-mysql-db.sh


# Set database parameters
DB_USER="your_username"
DB_HOST="localhost"
DB_NAME="your_database_name"
DB_FILE="your_db_file_path"
DB_PASSWORD="your_password"  # Optional: hardcode your password here

DB_SOCKET=""  # Set default socket or empty if not using
# DB_SOCKET="/tmp/mysql_3306.sock"  # Set default socket or empty if not using

# Check if the SQL file exists
if [ ! -f "$DB_FILE" ]; then
  echo "Error: SQL file does not exist."
  exit 1
fi

# Check if a socket file is used
if [ -n "$DB_SOCKET" ] && [ -S "$DB_SOCKET" ]; then
  SOCKET_OPTION="-S $DB_SOCKET"
else
  SOCKET_OPTION=""
fi

# Check if DB_PASSWORD is set
if [ -z "$DB_PASSWORD" ]; then
  # Prompt for the MySQL password if not set
  echo -n "Enter MySQL password for user $DB_USER: "
  read -s DB_PASSWORD
  echo
fi

# Run the MySQL import command
if [ -n "$SOCKET_OPTION" ]; then
  mysql $SOCKET_OPTION -u "$DB_USER" -p"$DB_PASSWORD" "$DB_NAME" < "$DB_FILE"
else
  mysql -h "$DB_HOST" -u "$DB_USER" -p"$DB_PASSWORD" "$DB_NAME" < "$DB_FILE"
fi

if [ $? -eq 0 ]; then
    echo "Database import successful."
else
    echo "Database import failed."
fi

This is a Bash script to import a MySQL database using either standard TCP/IP connections or Unix sockets. Designed to support both manual password entry and automated deployments with hardcoded passwords.

It checks for the presence of the specified SQL file before proceeding with the import to prevent errors, and it provides clear success or failure messages based on the import results.

This utility is ideal for developers and system administrators who frequently manage database migrations and updates.

Usage Instructions

If you are using a socket you can provide that in the script (DB_SOCKET) or leave it empty.

sh import-mysql-db.sh

OR

chmod +x import-mysql-db.sh ./import-mysql-db.sh
