Starting in version 0.16.1, Memos has added support for using MySQL as the database driver.

Enabling MySQL

By default, Memos uses SQLite as the database driver. To switch to MySQL, you need to specify two additional arguments when starting Memos:

• --driver mysql : Specifies that Memos should use mysql instead of the default sqlite.

• --dsn dbuser:dbpass@tcp(dbhost)/dbname: Provides the connection details for your MySQL server.

Then you can start Memos with docker like this:

docker run -d --name memos -p 5230:5230 -v ~/.memos/:/var/opt/memos ghcr.io/usememos/memos:latest --driver mysql --dsn 'root:password@tcp(localhost)/memos_prod'

And you can also set these via environment variables:

MEMOS_DRIVER=mysql
MEMOS_DSN=root:password@tcp(localhost)/memos_prod

Migrating data from SQLite to MySQL

If you are already using Memos with SQLite, you can migrate your data to MySQL with the following command copydb:

/usr/local/memos/memos --driver mysql --dsn 'dbuser:dbpass@tcp(dbhost)/dbname' copydb --from sqlite://path_to_your_memos_prod.db

This will copy all data from the SQLite database specified by --from into the MySQL server. If your Memos instance is running in Docker, you can execute this command inside the container.
