MySQL Backup & Restore Tool

🇰🇷 (한국어) | 🇬🇧 (English)

A ruby script tool for backing up and restoring MySQL data.

Requirements

• Tested on linux, Mac OS X environments only
• ruby, mysql, mysqldump, gzip, zcat commands must be installed

Configuration

Create a config-.json file under the current directory according to the database environment.

{
  "dataTables": [],
  "ignoreTables": [],
  "dbInfo": {
    "host": "localhost",
    "port": 3306,
    "user": "root",
    "password": "",
    "database": [
      "test_db"
    ]
  }
}

• dataTables - allows you to set a column for putting a --where condition to backup only the latest(3 days) rows of a large table.
  • { "name": "table_name", "where": "column_name" }
• ignoreTables - allows you to set which tables should be excluded from backups as unused tables.

Install

gem install mysql_db_tool

Data backup

mysql_backup -e {env} -i {backup id} -r {run?} --gzip

you can get help by running mysql_backup -h

• env - default (local), key to find the configuration file. e.g.) config-local.json

• backup id - default (0), ID to use when restoring as a string

• run? - Default (false), you can check in advance which command will be executed, if true, it will be executed

• gzip? - default (true), whether to compress with gzip or not

• DUMP_OPTIONS - you can set common mysqldump command options by this Environment variable, if not set, it will use default options for mysqldump. (--single-transaction --skip-lock-tables)

After execution, a directory named "backup-{backup id}" will be created under the current directory.

restore backup data

mysql_restore -e {env} -i {backup id} -r {run?} --drop-all-tables

you can get help by running mysql_restore -h

• drop all tables? - Default (false), to keep existing tables, or true, which may cause integration check error if not set to true

Generate creating db and user sql

You can generate a sql script to create a db and user.

gen_create_db_user {user} {password} {db} {host}
