Running ArchivesSpace against MySQL

Out of the box, the ArchivesSpace distribution runs against an embedded database, but this is only suitable for demonstration purposes. When you are ready to starting using ArchivesSpace with real users and data, you should switch to using MySQL. MySQL offers significantly better performance when multiple people are using the system, and will ensure that your data is kept safe.

Download MySQL Connector

ArchivesSpace requires the MySQL Connector for Java, which must be downloaded separately because of its licensing agreement. Download the Connector and place it in a location where ArchivesSpace can find it on its classpath:

     $ cd lib
     $ curl -Oq http://central.maven.org/maven2/mysql/mysql-connector-java/5.1.39/mysql-connector-java-5.1.39.jar

Note that the version of the MySQL connector may be different by the time you read this.

Set up your MySQL database

Next, create an empty database in MySQL and grant access to a dedicated ArchivesSpace user. The following example uses username as and password as123.

NOTE: WHEN CREATING THE DATABASE, YOU MUST SET THE DEFAULT CHARACTER ENCODING FOR THE DATABASE TO BE utf8. This is particularly important if you use a MySQL client to create the database (e.g. Navicat, MySQL Workbench, phpMyAdmin, etc.).

NOTE: If using AWS RDS MySQL databases, binary logging is not enabled by default and updates will fail. To enable binary logging, you must create a custom db parameter group for the database and set the log_bin_trust_function_creators = 1. See Working with DB Parameter Groups for information about RDS parameter groups.

     $ mysql -uroot -p

     mysql> create database archivesspace default character set utf8;
     Query OK, 1 row affected (0.08 sec)

     mysql> grant all on archivesspace.* to 'as'@'localhost' identified by 'as123';
     Query OK, 0 rows affected (0.21 sec)

Then, modify your config/config.rb file to refer to your MySQL database. When you modify your configuration file, MAKE SURE THAT YOU SPECIFY THAT THE CHARACTER ENCODING FOR THE DATABASE TO BE UTF-8 as shown below:

 AppConfig[:db_url] = "jdbc:mysql://localhost:3306/archivesspace?user=as&password=as123&useUnicode=true&characterEncoding=UTF-8"

There is a database setup script that will create all the tables that ArchivesSpace requires. Run this with:

scripts/setup-database.sh  # or setup-database.bat under Windows

You can now follow the instructions in the “Getting Started” section to start your ArchivesSpace application.

**NOTE: For MySQL 8. MySQL 8 uses a new method (caching_sha2_password) as the default authentication plugin instead of the old mysql_native_password that MySQL 5.7 and older used. This may require starting a MySQL 8 server with the --default-authentication-plugin=mysql_native_password option. You may also be able to change the auth mechanism on a per user basis by logging into mysql and running ALTER USER 'archivesspace' IDENTIFIED WITH mysql_native_password BY '123456';. Also be sure to have the LATEST MySQL Connector for Java from MySQL in your /lib/ directory for ArchivesSpace.
